Reassembly
23. Clean the mating faces of the engine and the
gearbox spacer.
24. Check:
- the presence of locating pins (1) on the engine
(Fig. 9),
- the tightness of the upper nut (M12) on the
engine adapter plate (Loctite 270),
- the tightness of the lower studs (M22) on the
gearbox spacer (Loctite 270).
25. Lightly lubricate the splines of main shaft (1)
(Fig. 10) with grease (type GN + Molykote) or
equivalent.
26. If necessary screw two supplementary diametri-
cally opposed guide studs into the gearbox.
27. Assemble the engine onto the gearbox spacer.
Reminder
If necessary, remove the starter and turn the flywheel
ring gear using a suitable tool. This will ease the
engagement of the vibration damper splines with
those of the main shaft. If there is resistance, do not
force it and find the cause of the problem.
28. When the elements are joined, remove the guide
studs (if fitted). Lightly grease the thread of the
screws and nuts with Loctite 270 or equivalent and
refit according to the marks made at disassembly.
