Engine
- Remove the two retainers indicated in the figure and the starter motor.
Before opening the engine crankcase, it is advis-
able to check axial clearance of the crankshaft. To
do this, use a plate and a support with appropriate
tool dial gauge.
Higher clearances are signs of wear on the sup-
porting surfaces of the crankshaft casing.
Standard clearance: 0.15 ÷ 0.40 mm
Remove the 11 crankcase coupling screws.
- Split the crankcases while keeping the driving
shaft inserted on one of the 2 half-crankcases.
Remove the driving shaft.
N.B.
The crankshaft of the 200 cm³ version has two steel shim
washers. Take note of their fitting position.
CAUTION
KEEP THE CRANKSHAFT IN ONE OF THE TWO HALVES
OF THE CRANKCASE WHEN SEPARATING IT. IF YOU FAIL
TO DO THIS, THE CRANKSHAFT MIGHT ACCIDENTALLY
FALL.
- Remove the coupling gasket of the crankcase
halves.
- Remove the two screws and the internal cover
shown in the diagram.
CAUTION
WHILE OPENING THE CRANKCASES AND REMOVING
THE DRIVING SHAFT, CHECK THAT THE THREADED
SHAFT ENDS DO NOT INTERFERE WITH THE MAIN BUSH-
INGS. FAILURE TO OBSERVE THIS PRECAUTION CAN
DAMAGE THE MAIN BUSHINGS.
- Remove the oil guard on the flywheel side.
