IMPORTANT INFORMATION
GASKETS, OIL SEALS, AND O-RINGS
1. All gaskets, seals, and O-rings should be replaced when an engine is
overhauled. All gasket 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.
LOCK WASHERS/PLATES AND COTTER PINS
All lock washers/plates
1
and cotter pins must be replaced if they are
removed. Lock tab(s) should be bent along the bolt or nut flat(s) after the bolt
or nut has been properly tightened.
BEARINGS AND OIL SEALS
Install the bearings
1
and oil seals
2
with their manufacturer’s marks or
numbers facing outwards. (In other words, the stamped letters must be on
the side exposed to view.) When installing oil seals, apply a light coating of
lightweight lithium base grease to the seal lips. Oil the bearings liberally when
installing.
CAUTION:
Do not use compressed air to spin the bearings dry. This causes
damage to the surface of the bearings.
CIRCLIPS
All circlips should be inspected carefully before reassembly. Always replace
piston pin clips after one use. Replace misshapen circlips. When installing
a circlip
1
, make sure that the sharp edged corner
2
is positioned opposite
to the thrust
3
it receives. See the sectional view.

LOCTITE
®
After installing fasteners that have LOCTITE

applied, wait 24 hours before
using the machine. This will give the LOCTITE
®
time to dry properly.
