Oil seals
When installing oil seals, observe the following.Installation of Oil Seals to Housings
(a) Check the seal lip for scratches and damage, and be sure to position the lip correctly.(b) Apply a small amount of grease to the periphery (housing contact surface) of the oil seal before installation.(c) Use an oil seal driver that guides the seal lip and presses the seal periphery, as shown in the diagram on the right. Striking the oil seal directly with a hammer causes seal damage and results in oil leaks.

Use an O-ring guide similar to the one shown in the diagram when installing an O-ring over the stepped portion, splines, threads or key grooves. Be sure to apply a small amount of grease to the O-ring before installation.

Bearing Driver(1) When installing a bearing, be sure to push the inner or outer race that fits into the installation position. (When the inner race fits into the installation position, push the inner race into position. When the outer race fits into the installation position, push the outer race into position.) Be sure to use a bearing driver similar to the one shown in the diagram.(2) Use of a press minimizes the impact on the bearing and ensures proper installation.
Using press for bearing installationLock Plates
Be sure to bend lock plates. The diagram on the right shows the methods of bending representative lock plates.

Generally, new split pins should be installed whenever split pins are removed. Be sure to bend split pins. Be sure to check spring pins for secure installation.Engine Inspection Record Sheet
