Check
• Measure crankshaft axial clearance (G) using a dial gauge.
• Read axial clearance moving shaft up and down.
Warning
To get correct values, exert a greater force.
Technical specications
Crankshaft axial
clearance
0.30...0.50 mm
Result: Read value outside tolerance values.
Action:
Crankshaft axial clearance adjustment (with engine removed)
Crankshaft axial clearance check
Crankshaft, countershaft, and relevant bearings
Preliminary operations
Engine oil drainage
Head disassembly
Gear lever disassembly
Engine left crankcase cover disassembly
Securing crankshaft at TDC
Starter motor idle gear disengagement
Flywheel disassembly
Crankcase left half disassembly
• Remove screws (1, 2, 3).
• Disassemble crankcase left half (4).
Warning
Due to sealant high adhesion, some engine parts could prove hard to disas-
