Installation

CAUTION
Always use appropriate tools to align fixing
holes. NEVER USE FINGERS OR HANDS.
1. Apply the torque settings listed on page 12.
2. Insert the three hooks of the chain in the eyelets
on the engine and, using the hoist, lift the assem-
bly off the platform support.
3. Position the engine on the front axle, trying to
avoid incorrect operations with the hoist so as not
to let the engine fan damage the fins of the radia-
tor, then join the two assemblies together with the
four retaining bolts.
4. Reposition the movable tool for dismantling trac-
tors 380000569 under the engine and place a
wooden block in between the point of contact be-
tween the tool and engine.
5. With the aid of the hoist, place the engine on the
tool 380000569 and remove the lifting eyelet pre-
viously fitted on the front of the engine.
6. Remove the fixed stand previously positioned
under the support of the groove of the drive of the
front axle and the wooden plug.
7. Refit the pipe joining the coolant pump to the bot-
tom of the radiator and the associated retaining
clamp.
8. Refit the oil vapor suction pipe, filter/intake man-
ifold connecting pipe and the pipe connecting the
radiator at the top to the thermostat valve, re--
installing the associated retaining clamps.
9. Fit the left--right hand side guard of the engine fan
and the three retaining bolts.
10. Remove the fixed U--bolt fitted beforehand under
the ballast support and the two wooden wedges
locking the front wheels.
11. Remove the old sealing compound from both
surfaces of the spacer between the engine and
the overdrive clutch housing, and do the same
also on the contact surface of the overdrive
clutch housing and on that of the engine.
12. Apply LOCTITE sealing compound on the en-
gine/spacer contact surfaces and fit the spacer
on the stud bolts screwed into the engine.
13. Also apply LOCTITE sealing compound on the
clutch overdrive casing surfaces.
14. Position wooden blocks under the rear wheels,
make sure that the hand brake is fully applied and
that all fixed and mobile stands are safely posi-
tioned.
SECTION 10 - - ENGINE - - CHAPTER 1
15. The installation phase described here requires
the presence of two or three workers to use the
movable tool for dismantling tractors 380000569
to move the engine/front axle assembly close to
the overdrive clutch casing.
16. In the phase of installing the engine/front axle as-
sembly to the overdrive clutch casing, it is neces-
sary to push on the front wheels, taking great
care in the end phase of coupling over both the
pipes and the cables/electrical connections to
prevent crushing between the two bodies. During
this phase, it is moreover necessary to turn the
crankshaft with the aid of the radiator cooling fan
to help the coupling between the sleeve and the
drive shaft.
17. Secure both assemblies by tightening all the
bolts locking the engine to the overdrive clutch
casing.
18. Remove the U--bolt previously fitted under the
clutch casing and recover the movable tool for
dismantling tractors 380000569.
19. Fit the electric cable connected to the fuse--hold-
er box and the retaining nut.
20. Working from the side of the starter motor, fit the
protective cable housing and the retaining nut.
21. Fit the electrical connections installed on the
brake pump and on the brake fluid reservoir.
22. Refit the power steering piping on the engine and
reconnect the electrical connections to the pres-
sure switch.
23. Refit the power steering return pipe with its
bracket and retaining bolt.
24. Refit the brake piping support and the two retain-
ing bolts.
25. Refit the condenser, air cooler and radiator
pipes.
26. Refit the dryer filter together with its support and
piping, tightening the two retaining bolts.
27. Refit the hood support, tightening the retaining
bolts.
28. Refit the support with the fuse--holder box on the
hood support, tightening the two retaining bolts.
29. Refit the support together with the relays protect-
ing the system on the hood support, fitting the two
retaining bolts.
30. Refit the brake fluid reservoir onto the support
and the two retaining clips.
