TSB : Pinion Flange & Oil Seal: Installation

Details

Install seal using installer (T79P-4676-A). Align marks on flange and pinion. Install flange and new integral nut and washer. Hold companion flange and gradually tighten nut. Rotate pinion occasionally and check pinion bearing preload often, until original preload is obtained. NOTE: Pinion nut should not be backed off to lessen preload. If this is done, a new pinion bearing collapsible spacer must be installed and new pinion nut tightened until proper preload is obtained.
