ALL REPLACEMENT PARTS
We recommend the use of genuine Yamaha parts for all replace-
ments. Use oil and/or grease, recommended by Yamaha, for
assembly and adjustment.
GASKETS, OIL SEALS, AND O-RINGS
1. All gaskets, seals, and O-rings should be replaced when an
engine is overhauled. All gaskets surfaces, oil seal lips, and
O-rings must be cleaned.
2. Properly oil all mating parts and bearings during reassembly.
Apply grease to the oil seal lips.
BEARINGS AND OIL SEALS
Install the bearing(s) 1 and oil seal(s) 2 with their manufacture’s
marks or numbers facing outward. (In other words, the stamped
letters must be on the side exposed to view.) When installing oil
seal(s), apply a light coating of lightweight lithium base grease to
the seal lip(s). Oil the bearings liberally when installing.
NOTICE
Do not use compressed air to spin the bearings dry. This
causes damage to the bearing surfaces.
