Crankshaft; Starter Clutch - Suzuki LT-Z90 Manual

Push the big end of the conrod to one side and measure the
side clearance using a thickness gauge. If the clearance
exceeds the service limit, replace the crankshaft assembly with
a new one or bring the deflection and the side clearance within
the service limit by replacing the worn parts (conrod, big end
bearing, crank pin, etc.) with new ones.

STARTER CLUTCH

INSPECTION
Install the starter driven gear onto the starter clutch and turn the
starter driven gear by hand to inspect the starter clutch for a
smooth movement. The gear turns one direction only. If a large
resistance is felt to rotation, inspect the starter clutch for dam-
age or inspect the starter clutch contacting surface of the starter
driven gear for wear or damage.
If they are found to be damaged, replace them with new ones.
DISASSEMBLY
• Hold the rotor using the special tool and remove the bolts.
