Reassembly
Advice for use
Use guide studs to assist reassembly of the engine
and gearbox.
53. Clean the mating face of the engine adapter plate
and gearbox spacer.
54. Check for the presence of dowels (1) on the
engine adapter plate (Fig. 24).
55. Coat the input shaft splines of the gearbox lightly
with AS767 grease or equivalent.
56. Screw two diametrically opposed guide studs to
the engine adapter plate or to the gearbox spacer.
57. Connect the engine to the gearbox spacer.
Reminder
If necessary, remove the starter and slowly turn
the flywheel ring gear using a suitable tool.
This will ease engaging the vibration damper
splines with those of the gearbox main shaft.
If there is resistance, do not force it and find the
cause of the problem.
58. When the two assemblies are joined, remove the
guide studs (if fitted).
Lightly smear the thread of each of the screws (1)
and (2) with Loctite 270 or equivalent. Position
them according to the marks made during
disassembly.
Tighten (Fig. 25):
- screws (1) to a torque of 120 Nm
- screws (2) to a torque of 735 Nm
