IMPORTANT : When replacing a part on one of bevel drive shafts, you MUST check bearing preloadand clearance between teeth to ensure optimum bevel drive operation and also limitoperating noise as much as possible.
NOTA : Refer to machine repair manual when removing and refitting bevel drive and components.

2 -INPUT AND OUTPUT PINION IDENTIFICATION AND POSITION
- 28 -
- Bevel gears are manufactured in pairs andmust not be replaced separately.
- Pairs are marked by an identical identificationnumber.
- 29 -
- A channel machined into input gear ensureseasy identification.
- 30 -
IMPORTANT :
- Tooth marked with an "X" on input gear.
- 31 -
- Must be positioned between teeth marked with"X" on output gear.
- Paint teeth marked with "X" on both gears, tolocate them more easily during assembly.

- Using suitable tool, remove seal from outputshaft housing as preload must be checkedwithout this seal.
- 51 -
- Refit calibrated spacer.NOTE : If your bevel drive has a spacer + set ofshims, you must replace them with a calibratedspacer** of same thickness.**: Bevel drive change 2.
- 52 -
- Clean and degrease shaft splines and flangewith cleaning product. Avoid letting it run ontobearings.
- Refit bearing on output shaft.
- 53 -
- Refit output flange without new compressionwasher 1.
NOTE: New compression washer 1 will be fittedafter adjusting preload.

Resistant torque check - Method 1
Resistant torque check - Method 2
- 54 -- Using a strain gauge, measure resistant torque
which must be between 1.1 and 2.2 Nm.- If necessary, change calibrated spacer to obtain
correct torque.
• Resistant torque decreases if calibrated spa-cer thickness is increased.
• Resistant torque increases if calibrated spacerthickness is decreased.
- Secure output shaft housing in vice.- Position bolt A in end plate B.- Secure rope to bolt and wrap around end
plate B two or three times.- Secure end of rope to 0 - 10 daN max spring
balance C.- Measure resistant torque which must be bet-
ween 1.8 and 3.6 daN.- If necessary, change calibrated spacer to obtain
correct torque.
• Resistant torque decreases if calibrated spa-cer thickness is increased.
• Resistant torque increases if calibrated spacerthickness is decreased.
NOTE : Before assembling output shaft definiti-vely, measure dimension C page 13 for inter-tooth adjustment.
- When resistant torque is adjusted, fit new seal 5in housing D.
- Place adhesive product 2 or 3 in the shaft splineand on bearing D1 bearing surfaces.
**** : Bevel drive change 4.- Apply thread lock 4 to shaft threads.- Fit new O ring 6.- Fit new compression washer 1 and tighten
NOTE : Fixing product 648 Item 3 has minimumsetting time of 12 hours.

- Refit calibrated spacer.NOTE : If your bevel drive has a spacer + set ofshims, you must replace them with a calibratedspacer** of same thickness.**: Bevel drive change 2.
- 39 -
- Clean and degrease shaft splines and flangewith cleaning product. Avoid letting it run ontobearings.
7 - BEVEL DRIVE / ENGINE ALIGNMENT ADJUSTMENT AND CHECK
- Refit bevel drive on machine.- Secure tool 14 to engine in place
of universal joint A.
NOTE: You can choose betweentwo sockets: moving socket withflange or moving socket with point.
- Push moving part towards beveldrive and check alignment withengine.
• If using moving socket with flan-ge, check that flange and bevelgear mounting holes line up.
• If using moving socket withpoint, check that point arrives incentre of bevel drive bolt head.
- If necessary, add washers 16between rubber mountings Band engine supports C (flywheelside).
NOTE: If you have to f i t twowashers 16 on each rubber moun-ting on flywheel side, you must fitone on each rubber mounting onopposite side. (In this case, checkposition of fan in radiator outlet).When assembling using twowashers 16, use new fixing screws17 (HM 16 - 60 ref. 58 590).- Tighten rubber mounting nuts as
shown.
- When alignment is adjusted, remove tool 14 and refit universal joint A.• Universal joint mounting bolt tightening torque A: 61-73 N.m (bolts are fitted with thread lock
