Disassembly
To remove the pinions (5) (6), it is necessary to
remove:
- the lift cover (see section 6)
- top cover at the rear PTO drive shaft, the driving
pinion and the layshaft (see section 7).
30. For access to the sensor, remove the left-hand ram
by removing the lower attachment and by discon-
necting the feed pipe. Remove the PTO sensor.
31. Remove the rear bearing and repeat operations 8
to 11.
32. Remove the pinions (5) (6).
33. Extract the roller bearing (1) and the deflector (2).
Reassembly
34. Check and clean all components. Replace any
defective parts.
35. Smear the deflector (2) with Loctite 648 on the
mating surface with the housing and put it with its
bore. Turn the opening upwards (Fig. 8).
36. Fit the roller bearing (1) in the housing, in abutment
with the deflector (2).
37. Lubricate the rings (3) (4).
38. Refit the pinions (5) (6) and screw two guide studs
in abutment on the pinion (6). The purpose of this
operation is to maintain the pinions (Fig. 4) in line
while refitting the rear bearing.

“Form A gasket 2” (sensor sealing or equivalent).
Adjust the sensor:
- Tighten the sensor home, without forcing, until it
comes in contact with the pinion (6).
- Unscrew the sensor by 3/4 turn.
- Tighten the nut (18) moderately and connect the
harness.
41. Refit the left-hand ram, install the lower attach-
ment and reconnect the feed pipe.
