6.3 Bearings
1. When installing a rolling bearing, be sure to push
the inner or outer race by which the bearing is
fitted. Be sure to use a bearing driver like the one
shown.
2. Whenever possible, use a press to minimize shock
to the bearing and to assure proper installation.
6.4 Lock Plates
Bend lock plates against the flats of the nuts or bolt
heads as shown.
6.5 Split Pins and Spring Pins
Generally, split pins are to be replaced once disturbed.
Insert the pin fully and spread it properly. Drive each
spring pin into position to hold it in place after later
installation of parts has been completed.
