REAR COVER SEAL 11

SPEEDOMETER DRIVEN GEAR 12

THREE-SPEED GEAR SHIFT LINKAGE 13

FOUR-SPEED GEAR SHIFT LINKAGE 17

TRANSMISSION 18

The three-speed transmission incorporates synchromesh engagement on all forward speeds. Gear selection is by a lever mounted on the steering column and connected by linkage to the transmission striking lever shaft.

The rear of the main drive pinion is supported by a ball bearing in the front cover and a spigot at the front end engages a bush in the crankshaft.

The mainshaft is supported at the front by needle rollers in the main drive pinion, and by a ball bearing in the rear cover. The mainshaft gears operate direct on copper plated journals.

The synchromesh mechanism incorporates two clutch assemblies splined to the mainshaft. The first speed clutch incorporates the reverse gear.

The layshaft gear is supported at each end by needle rollers on a stationary shaft.

The reverse pinion incorporates two bushes and rotates on a stationary shaft.

Two striking forks are secured to rods located longitudinally in the transmission casing. Mounted transversely below the rods is the striking lever shaft. A striking lever secured to each end of the shaft engages a slot in each striking fork rod.

When the gear shift lever is operated, movement is conveyed to the striking lever shaft. The shaft is moved transversely and a striking lever engages the slot in the appropriate striking fork rod. When the striking lever shaft is rotated the rod and fork then moves the clutch towards the selected gear.

Page 13: &Rear Axle - vauxhallfdregister.co.ukvauxhallfdregister.co.uk/wp-content/uploads/2017/03/Synchromesh... · FOREWORD Contents. The main subjects dealt with are listed on page 2. An

The four-speed transmission is similar in basic design to the three-speed unit_ Gear selection is by a central lever mounted on the rear cover and connected by linkage to the transmission striking lever shaft.

The mainshaft first and second gear is bushed and operates on a sleeve pressed on the main­shaft. The reverse pinion is a sliding gear incorporating a groove in the hub of the gear to take the reverse striking fork mounted in the transmission bottom cover.

The striking lever shaft is longer and extends through the left-hand side of the transmission casing into a reverse stop housing, incorporating a locking ball and spring, bolted to the side of the casing.

When reverse is selected, the shaft is moved transversely beyond the first and second speed position, overcoming the locking ball spring pressure, until the lower end of the third and fourth striking lever engages the reverse shift fork in the bottom cover. Rotary movement of the striking lever then moves the reverse pinion into engagement with the gear on the first and second clutch, and the layshaft gear.

REAR COVER SEAL

Oil leakage from the transmission rear cover is

prevented by a spring-loaded seal. Seal can be

renewed with transmission in car, and can be

driven off with a chisel applied alternately each

side of seal outer casing.

The speedometer driven gear and shaft is carried

in a housing attached by two screws to the rear

cover. Oil leakage from the shaft is prevented by

a spr'ng-loaded seal.

T e number of teeth on the driven gear is de­

pendant on axle ratio and tyre size.

SP727 c SP729

To ensure a driven gear with the appropriate number of teeth meshes correctly with the driving gear on the mainshaft, the bore of the driven gear housing is offset. The position of the eccentric is identified by a flat on the housing.

For 15 tooth gears flat must be positioned as at 'A', 17 and 18 tooth as at 'B' and 19 as at 'C'.

Housing screws are locked by staking.

THREE-SPEED GEAR SHIFT LINKAGE

II

2

Gear selection on the three-speed transmiss ion is by a lever mounted on the steering column, in a housing (2) which is free to move rad ial ly. The inner end of the gear shift lever engages a control tube ( 1) which is keyed to the lever housing, but free to move independently of the housing in an endwise direction. Attached to the lower end of the control tube is a change speed lever ( 1 0).

A selector lever (11) pivots on a bracket at the lower end of the steering column. The upper end of the lever is forked, to engage the boss of the change speed lever.

Mounted between the transmission and the underbody sidemember is a cross-shaft (7), carried in a bushed bracket and coupled to the transmission striking lever shaft (8). A bell­crank lever (3) is mounted on the cross-shaft support bracket, and incorporates a pin (5) which engages in a grooved collar ( 4) on the cross-shaft.

An adjustable rod (9) connects the selector lever on the steering column to the bellcrank lever, and a control rod (6), also adjustable, couples the control tube change speed lever to a lever on the cross-shaft.

14

THREE-SPEED GEAR SHIFT LINKAGE (contd)

Up and down movement of the gear shift lever causes endwise movement of the control tube, which in turn operates the bellcrank lever through the selector lever and rod. The bellcrank lever moves the cross-shaft and transmission striking lever shaft in an endwise direction, so that one of the striking levers engages the appropriate striking fork rod.

Radial movement of the gear shift lever causes the cross-shaft and transmission striking lever shaft to rotate, so moving the striking fork into the engaged position.

THREE-SPEED GEAR SHIFT LINKAGE - Adjustment

With gear shift lever in second and third speed

plane, height 'A' of lever should be 3.30 in.

0 1005

To correct gear shift lever height, adjust selector

rod at adjuster 'B'. Lengthening rod will lower

gear shift lever.

When in neutral , rad·a position 'A' of gear shift

lever shou d be 5= above horizontal.

Gear selection on the four-speed transmission is by a central lever located on top of an inver­ted U-shaped carrier ( 1) by a bolt (2). The carrier pivots on bushes pressed into the carrier and bracket (3) bolted to the top of the transmission rear cover. The outer leg of the carrier extends downwards and is connected by a control rod (5) to the transmission striking lever shaft coupling (6). The spherical end of the gear shift lever engages the carrier bracket pivot shaft (4) and is loaded by a spring and pad through the centre of the shaft. A selector bar (7), pivots on a fulcrum bracket (8) integral with the transmission casing, and connects the carrier bracket shaft to the transmission striking lever shaft coupling.

Sideways movement of the gear shift lever causes the selector bar to pivot on its fulcrum bracket, so that the transmission striking lever shaft moves transversely, bringing one of the striking levers into engagement with the appropriate striking fork rod.

Forward or rearward movement of the gear shift lever causes the transmission striking lever shaft to rotate, so moving the striking fork into the engaged position.

FOUR-SPEED GEAR SHIFT LINKAGE (contd)

Gear shift lever carrier bolts ( 1) are accessible

from inside car. After removing bolts and dis­

connecting selector bar and control rod from

carrier, gear shift lever together with carrier,

can be removed. Note spacer (2) between

carrier and transmission rear cover.

To ensure full engagement of a selected gear,

dimension 'A' on control rod must be 1.35 in.,

and 'B' 8.90 in. between hole centres.

Lubricate all moving surfaces with recommended grease when reassembling linkage.

TRANSMISSION

The transmission assembly is secured to the clutch housing by four bolts, the two lower of which are inside the clutch housing.

The rear of the transmission is supported by a rubber mounting on a detachable crossmember.

TRANSMISSION-· Removal

Where overdrive is fitted, before commencing removal operations, drive the car in third or top gear, engage overdrive then disengage the overdrive with the clutch pedal depressed and leave in this condition ready for removal.

If, prior to removal, the overdrive was disengaged during acceleration the splines in the planet carrier and in the uni-directional clutch may remain torsionally loaded on the transmission mainshaft. This condition will prevent the overdrive being withdrawn from the transmission mainshaft when separating the two units.

These contours engage with a similar contour formed in the engagement teeth of the corres­ponding mainshaft gears and main drive pinion.

The keystone contour provides anti-jump-out characteristics and must not be mistaken for localized wear.

On three-speed transmission, external splines on

first speed clutch and reverse gear hub are stepped

on reverse drive side. Extent of stepped part is

Good synchromesh operation will depend largely

on condition of synchronizing ring. Mis-shapen

teeth will create baulking trouble. Rocking of

ring on gear cone indicates ovality in either ring

or cone, or both, resulting in insufficient grip.

Wear on rings or gear cones can be assessed by

comparing frictional grip and relative location of

ring on cone with new components.

REAR AXLE - Reassembly (contd)

In production built axles, lateral location of the differential, and bearing pre-load, are controlled by spacers installed behind the bearings. The spacers range in thickness from 0.200 to 0.243 in.

For service, spacers 0.100 and 0.101 in. thick, and shims 0.003 in. thick are available. With a combination of two service spacers and a varying number of shims, the entire range of production spacers can be covered in steps of 0.001 in.

Spacers and shims must be selected, and bearing pre-load checked, before installing pinion. To make a preliminary assessment of spacer and shim thickness required, proceed as follows:

(a) Assemble differential and bearings to axle housing and place two service spacers between each bearing and housing.

(b) Insert an equal number of shims between each pair of spacers to eliminate and float in bearings.

(c) Remove differential and add a shim to one of the spacer and shim packs.

To facilitate assembly prior to checking bearing

pre-load, place selected spacers and shims in axle

housing before installing differential and bearings.

Before checking bearing pre-load, tighten bearing cap bolts to specified torque, and at the same time lightly tap bearing caps and rotate differential to settle bearings.

To check side bearing pre-load, use a spring

balance in conjunction with a length of twine

wound around differential case flange. Specified

pre-load must be obtained by adding or remou-

ing shims, or changing spacer thickness.

Specified torque must be applied to bearing cap

bolts before each pre-load check is carried out.

Run-out of hypoid gear should be checked afte

correct bearing pre-load has been obtainec.

run-out is in excess of specified figure, gear must

be removed from differential and a chec

for foreign matter on mating faces, or a cnec

made for run-out of differential case f'ange.

After removing differential on complet ion of run-out check, selected spacers and shims must be retained in a safe place for final assembly.

Always renew compressible spacer (1 ), pinion

bearing nut (2), oil seal (3), dust shield (4) and

flange nut (5) when reassembling pinion.

REAR AXLE -Reassembly (contd)

871

Correct endwise location of the pinion, relative

to the hypoid gear, is obtained by shims inter­

posed between the pinion rear bearing and the

bearing abutment face in the axle housing.

Shims must be calculated to compensate for the

manufacturing tolerances of the pinion bearing,

pinion and axle housing. Shims are serviced in

three thicknesses.

The three controlling factors which together determine total thickness of shims required are as follows:

Item 1 - - Actual thickness of pinion rear bearing~

To measure bearing, mount on Jig Z8391 and

settle bearing by pressing down on outer race

while rotating it in each direction. Measure bear­

ing and jig plate at two opposite points, and

subtract jig plate thickness to obtain actual bear­

ing thickness. To obtain shim correction for

bearing, subtract actual bearing thickness from

theoretical thickness which is 1.1643 in. on

Ventora and Victor '3300' or 0.9626 in . on

Victor and Victor '2000'.

Where bearing thickness is same as theoretical

thickness no shim correction is necessary.

Item 2- Depth of pin ion rear bearing abutment

When assembling pinion in axle housing, place

a new compressible spacer over pinion shaft and

while supporting pinion, tap front bearing inner

race into position on shaft, using Installer VR2034

for Ventora and Victor '3300' and VR2053 for

Victor and Victor '2000'.

Before installing pinion bearing nut, smear threads of nut and pinion shaft with oil.

S98 S4288

Pinion bearing nut must be tightened progres­sively to compress spacer while making frequent checks with Gauge 598, until specified bearing pre-load is obtained. If pre-load limit is exceeded due to overtightening, compressible spacer must be renewed as it will have become over-compres­sed for use at correct pre-load.

Do not stake nut at this stage, or install pinion shaft seal and dust shield, as it may be necessary to remove pinion later, to adjust bearing shim thickness.

ensure magnetic plate is secured to oad retainer

in position shown.

When assembling previously selected sic ::: oearmg .....

spacers and shims in axle housing, numbe

shims between spacers on right-hand sice r.1 .....

initial clearance between pinion and hypo-

gear teeth.

Backlash between hypoid gear and pinion must

be checked at heel of tooth. To obtain spec ified

backlash, shims must be interchanged side for

side. Preliminary backlash checks can be made

without installing bearing caps, but a final check

must be made with caps installed and bolts tight­

ened to specified torque.

REAR AXLE- Reassembly (contd)

Having obtained correct backlash, a gear marking

check must be carried out to ensure hypoid gear

and pinion are correctly meshed. Use Handle

Z8304 to rotate pinion while applying a load on

hypoid gear.

Correct hypoid gear meshing should produce marking 'A'. Marking 'B' indicates that pinion is too far out of engagement with gear, necessitating increased pinion rear bearing shim thickness. If marking is as 'C', pinion must be relocated by decreasing shim thickness.

Where it is necessary to increase total thickness of shims, compressible spacer must be renewed, as it will have become over-compressed for correct pre-load.

Spacer renewal is not necessary when reducing shim thickness as spacer must be compressed further to obtain correct pre-load.

Having obtained correct gear meshing, lock pinion

bearing nut by staking lip of nut into slot in

pinion shaft with Lever VR2067. Do not use a

punch as this may upset bearing pre-load.

To ensure adequate staking, vee-block of lever

should be adjusted so that lower end of lever is

approximately parallel with pinion shaft before

'" applying pressure to nut.

Before installing pinion shaft seal, smear lip of

seal and mating face of shaft with oi . Seal must

be located in housing, open side first, so that

dimension 'A' is 0.19 in. on Victor and Victor

'2000' and 0.29 in. on Ventora and V ictor

'3300'.

Use Installer VR2053 on Victor and

'2000' and Installer VR2034 on Ventora o.

Victor '3300' to install pinion shaft seal.

Dust shield must be driven on pinion until

sion 'A' is 0.36 in. on Victor and Victo~ ' 2

and 0.62 in. on Ventora and Victor '3300'.

Coupling flange nut must be tightened to specified

torque. Before staking nut, support flange on bock

of wood.

FOUR-SPEED GEAR SHIFT LINKAGE

On later models a revised gear shift linkage is used.

The linkage consists of a gear shift upper lever ( 11) pinned to a finger (2) which pivots in an intermediate lever ( 1 ). The intermediate lever pivots on a bush (8) pressed into a carrier bracket (7), which is bolted to the transmission rear cover. The outer leg of the intermed­iate lever is extended down­wards and is connected to the quadrant-shaped striking lever shaft coupling (6) by a cont_rol rod (5). The spherical end of the finger engages in the intermediate lever pivot shaft (10) which runs in the carrier bracket bush, and is loaded by a spring and pad (9) in the centre of the shaft. A selector bar ( 4) engages a grooved adjuster (3) in the lever pivot shaft and connects the pivot shaft to the striking lever shaft coupling. The selector bar pivots on a shouldered bolt attached to a lug on the

Accidental selection of reverse gear is prevent­ed by a stepped abutment (3) in a housing (2) at the lower end of the upper lever contacting a corresponding step (4) on the intermediate lever. To select reverse the abutment is lifted by a cable ( 1) passing through the centre of the gear shift lever and connected to a lift collar at the top of the lever.

Cable renewal necessitates removal of the gear

shift lever assembly.

To withdraw gear shift lever assembly, remove gear shift finger pivot pin (retained by an E­clip). Access to pivot pin is gained by raising gear shift boot. Console is retained by screws, the front two of which are accessible after removal of ash tray on Victor models.

Cable can be disconnected from lift collar by loosening clamp screw (arrowed) after pulling off lever grip.

On overdrive models, lever grip includes overdrive switch and grip is threaded to lever shroud. Grip may be unscrewed after prising off top of grip and disconnecting wires from switch.

To withdraw cable from lower end of lever, remove gear shift finger and stepped abutment, both of which are pinned to lever.

The intermediate lever pivot shaft bush is an interference fit in the carrier bracket and is retained by a circlip. If bush requires renewal, it must be pressed out of carrier bracket from selector bar side.

FOUR-SPEED GEAR SHIFT LINKAGE (Contd)

Bush must be installed with cut-away section uppermost and flats parallel to the base of carrier bracket.

On reassembly, smear all working parts with recommended lubricant.

Remove any excessive side clearance in the selector bar pivot by adding special washers between bar and I ug. I nsta II washers with convex side towards lug.

When installing cable, insert the compression spring into lower end of lever before threading cable and connector up the lever.

After assembling gear shift upper lever to intermediate lever, adjust cable length so that clearance 'A' between the underside of abut­ment and top of intermediate lever is 0.02/0.04 in.

Check that selector bar is fully engaged in groove of adjuster. A set can be introduced in the bar to provide full engagement.

Select first or second gear and set adjuster bolt in lever pivot shaft so that clearance 'B' is 0.012/0.020 in.

TRANSMISSION/OVERDRIVE UNIT- VX4/90 On VX4/90 a four-speed synchromesh transmission with Laycock Type J overdrive is standard equipment. Service information is the same as given for four-cylinder Victor models.

TRANSMISSION MAINSHAFT LUBRICATION

As the copper plating is deleted from later mainshafts, it is important that an unplated shaft is smeared with recommended lubricant (not oil), before assembling the gears to the shaft.

FOUR-SPEED TRANSMISSION On later transmissions the r~werse stop mechanism is incorporated in the gear shift lever, and the end of the striking lever shaft is sealed by a cover in the casing except when a reverse lamp switch is fitted. When installing switch, assemble an 0-ring to groove in switch body.

Assemble coupling to striking lever shaft so that hole in coupling is towards top of trans­mission casing.

TRANSMISSION/OVERDRIVE UNIT OIL LEVEL

After installing a transmission/overdrive unit it is important that the transmission oil level is checked after operating the overdrive to ensure the oil passages and cylinders are filled. It is not sufficient to run the engine with the transmission in neutral since in this condition the overdrive pump is inoperative.

PROPELLER SHAFT

55882

On some cars the universal joint trunnion bearing races are retained in the yoke by staking, instead of by snap rings.

Where renewal of a universal joint is indicated, a replacement propeller shaft complete with univP.rsal joints must be installed.

REAR AXLE - VX4/90

Service information for the VX4/ 90 rear axle is the same as given for four-cylinder Victor models.

REAR AXLE - Four-cylinder Models

On later four-cylinder models a revised rear axle is used. The axle is similar to earlier units

except that the pinion shaft is shorter and the propeller shaft coupling flange seats directly

against the pinion front bearing inner race . The pinion shaft seal contacts the outside of the

flange sleeve.

AXLE SHAFT BEARING REMOVAL PLATE AND ADAPTOR

Removal Plate VR2077 and Adaptor VR2079 supersede Z8461 and Z8475 for removal of the axle shaft bearing on four-cylinder saloons.

On six-cylinder models and estate cars use Removal Plate VR2077 and Adaptor VR2078.

AXLE SHAFT WHEEL BOLT RENEWAL

On later models the wheel bolts are not peened into the axle shaft flange, which obviates remov­al of the axle shaft when renewing a wheel bolt.

To renew bolt, drive out existing bolt and draw in new bolt using a distance tube and wheel retaining nut.

When installing a replacement axle shaft, wheel bolts must be pressed into flange before install­

ing shaft.

14

HYPOID PINION SHAFT SEAL­Four-cylinder Models (Extended Pinion Shaft)

On later four-cylinder models with an extended

hypoid pinion shaft a revised pinion shaft

seal is used. When installing, smear periphery of seal casing with jointing compound and locate seal in axle housing so that dimension 'A' is 0.26 in., to avoid the possibility of a foul with the threads on the pinion shaft. The dust shield must be located so that dimension '8' is 0.42 in.

HYPOID PINION SHAFT SEAL­Four-cylinder Models (Short Pinion Shaft)

On later axles a short pinion shaft is used and the seal contacts the outside of the flange sleeve.

If pinion shaft seal is to be renewed without completely disassembling rear axle, coupling flange nut must be retained for re-use. This will enable correct pinion bearing pre-load to be restored on reassembly.

Before installing seal, grind a slot away from and similar to existing slot in pinion shaft, to pro­vide a new location for staking nut.

Install seal, open side first, with Installer V R 2053 so that it either contacts shoulder in axle housing or seal case is flush with end of housing, whichever occurs first.

Before installing coupling flange, smear lip of seal and coupling land with recommended lub­ricant.

Coupling flange nut must be tightened so that original nut staking and pinion shaft slot are aligned. Do not overtighten nut. This align­ment is essential to restore correct pinion bearing pre-load.

Support flange when staking nut into new slot ground in pinion shaft.

Dl FFERENTIAL PINION SHAFT LUBRICATION

As the copper plating is deleted from later differential pinion shafts, it is important that an unplated shaft is smeared with recommended lubricant (not oil), before installation.

AXLE HOUSING SHIM CORRECTION FIGURES

The shim correction necessary to compensate for any deviation from the designed depth of the pinion rear bearing abutment in the axle housing is marked in thousandths of an inch on the axle housing rear face. Any figures adjacent to the bearing lands should be ignored.

HYPOID PINION BEARING SPACER

On later axles a washer is used between the compressible spacer and the pinion front bearing inner race. To compensate for the washer thickness a shorter spacer, of length 0.577/0.585 in. on four-cylinder models and 0.478/0.486 in. on six-cylinder models, is used. On early axles the length of the spacer is 0.657/0.665 in. (four-cylinder models) and 0.558/0.566 in. (six-cylinder models).
