Carefully examine the engine crankcase halves.
Check that the surfaces of the crankcase halves are perfectly flat using a reference surface.
Check that the bearings (1) and (18), and the bushings (2) and (17) are in optimum conditions. Note that the main bearings must always be changed in pairs (refer to the procedure below in "main bearings").
Note
When overhauling an engine it is good practice to renew all the crankcase half bearings.
After having renewed the gearbox shaft bearings (28) and (9), secure them in the crankcase half with the spacers (21) and the retaining plate (10).
At each overhaul it is recommended to renew also the seal (8) on the outside of bearing (9).
Renew the bearings (7) and (23) on the ends of the gearbox shafts and timing belt driveshaft bearings (4) and (15).
Take care not to lose the shim (6) interposed between the bearing (7) on the end of the gearbox primary shaft and the chain side crankcase half
The seal (14) on the external side of the roller bearing (15) must be renewed at each engine overhaul.
Check that the oilways are free of restrictions or clogging. Check the condition of locating bushes (22). If apparently distorted or loose in their seats, change them using proper tools. When the locating bushes (22) are hard to remove from casing, use a left-hand tap to force bushes out.
Important
The bushes (22) must always be renewed when they have been removed using the above procedure.
Remove the bearing (23), the circlip (5) and the roller bearing (4).
Overhaul of the flywheel-alternator assembly
Examine the inner part of alternator rotor (24) for signs of damage. Check
that the starter clutch is working properly and
that the needle races do not show signs of wear or damage of any kind. If there
is any malfunction, remove the whole
assembly.

On the diavel, the +15v (key on power) voltage does not come from a
conventional ignition key, but from pin 30 of the
hands free relay. This relay is switched to closed state by the hands free unit
when the latter enables power on for the
ignition and engine. The hands free relay receives +30v ...
