REPLACEMENT PARTS
1. Use only YAMAHA genuine parts for
replacement. Use oils/greases reco-
mmended by YAMAHA for mounting and
adjusting. Other brands may seem similar
in terms of function and appearance, but
have lower quality.
1. All gaskets, retainers and O-rings must be
replaced when overhauling the engine. All
gasket surfaces, retainer lips and O-rings
must be clean.
2. Apply oil on all points and roller bearings
when mounting. Apply grease on the
retainers’ lips.
Do not use compressed air for drying the
roller bearings. This will cause damages to
the roller bearing surfaces.
CAUTION:
1. Install the roller bearings 1 and retainers
2 ‚ with the manufacturer’s marks facing
out. (In other words, the stamped letters
must be exposed for facilitating the identi-
fication). When installing the retainers,
apply a thin lithium-based grease layer on
the retainer’s lips. Apply oil when installing
the roller bearing.
1. All lockwashers/cotter pins 1 must be
replaced when removed. The cotter pin
legs must be folded around the bolts or
nuts after applying the specific torque.
