CAUTION
Always install new mono-hook circlips. If circlip
installation fails at the first attempt, always retry with a
new one because, on a second attempt, the circlip will
lose its normal retaining capabilities.
▼
CAUTION
Circlips must not move freely after installation; if so,
replace them. Clean cylinders and crankcase mating
surfaces with Loctite Chisel (P/N 413708500). Coat
crankcase mating surface with Loctite 518 (P/N
293800038). Choose the right gasket thickness according
to combustion chamber volume. Refer to LEAK TEST
AND ENGINE DIMENSION MEASUREMENT. Install it on
the crankcase. Coat gasket with Loctite 518.

CAUTION
Always install a gasket of the proper thickness. Failure to
do so may cause detonation and severe engine damage.
Before inserting piston in cylinder, lubricate the cylinder
