LOCK WASHERS/PLATES AND COTTER
PINS
1. All lock washers/plates "1" and cotter pins
must be replaced when they are removed.
Lock tab(s) should be bent along the bolt or
nut flat(s) after the bolt or nut has been prop-
erly tightened.
BEARINGS AND OIL SEALS
1. Install the bearing(s) "1" and oil seal(s) "2"
with their manufacturer's marks or numbers
facing outward. (In other words, the
stamped letters must be on the side ex-
posed to view.) When installing oil seal(s),
apply a light coating of lightweight lithium
base grease to the seal lip(s). Oil the bear-
ings liberally when installing.
Do not use compressed air to spin the bear-
ings dry. This causes damage to the bearing
surfaces.
IMPORTANT INFORMATION
CIRCLIPS
1. All circlips should be inspected carefully be-
fore reassembly. Always replace piston pin
clips after one use. Replace distorted cir-
clips. 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.
