gearbox spacer (Loctite 270).
26. Coat the input shaft splines of the gearbox lightly

OTE: If necessary, remove the starter and turn the
flywheel ring gear using a suitable tool. This will ease
engaging 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.
29. When the elements are joined, remove the guide
studs (if fitted). Lightly smear the thread of the
screws and nuts with Loctite 270 or equivalent and
refit according to the marks made during
disassembly. Tighten to the required torques
