Note: When press-fitting the small end bush to the connecting rod, align the oil aperture of the small end bush with that of the connecting rod.
3. Connecting rod large end play
Fig. 88
Measure the connecting rod large end play with a special tool (No. N026 STANDARD FEELER GAUGE)' and it is good if the measured value is in the range of 0.004 - 0.008 in. (0.110 - 0.214 mm).
4. Connecting rod deflection
Fig. 89
Check the connecting rod deflection with a conrod aligner, and if the measured value is not satisfactory, correct the connecting rod with a press or replace it.
Connecting rod less than 0.002 in. per 3.94 in. deflection (less than 0.04 mm per 100 mm)
Distance between 4.84 ± 0.002 in. the large end (123±0.05 mm) and small end
Note: On the side of the connecting rod cap is inscribed one of the weight marks (8, C, D, E, F, ( G and H).
5. Connecting rod bearing metal
Fig. 90
Check the connecting rod bearing metal for scrape and damage, and if it is defective, replace it.
Note: Connecting rod bearing metals are available in three kinds of the undersize metal, 0.01 in., 0.02 in. and 0.03 in. (0.25 mm, 0.50 mm and 0.75 mm). \
This hydraulic mechanism is developed by SATOH, and equipped with a height control (position control), flow control and lift control. The hydraulic pump is of the gear type (Kayaba-Dowty, G P1 ), and driven directly by the engine crankshaft main pulley. Accordingly, while the engine runs, the oil

Fig. 1 Hydraulic System
The oil lock valve is of the in-I ine check valve design. When the oil enters the cylinder, it pushes the lock valve to open. Once the oil enters the cylinder, it forces the lock valve against the seat by means of the pressure generated by the weight of the implement and spring pressure. Accordingly, the heavier the weight of the implement, the greater the pressure against the lock valve.
is constantly delivered. The oil pressure is regulated by the control lever. When the control lever is moved, the spool valve operates, and then the spool valve causes the unload valve to move, thereby moving the ram piston located in the ram cylinder.

While in farming operations, the lock valve opening can be freely adjusted by the lever. This makes it possible to regulate the implement lowering speed ranging from "slow down" (while seeding) to "quick down" (while plowing).
