Pinion Flange & Oil Seal: Installation

Install seal with seal installer (T79P-4676-A). Align companion flange-to-pinion shaft marks and install flange. Install new pinion nut. Hold companion flange, then tighten nut, taking frequent preload readings until preload is at original setting. Install propeller shaft, brake drums and wheels.

CAUTION: Under no circumstances should pinion nut be backed off to lessen preload. If this is done, a new pinion bearing spacer must be installed and nut retightened until proper preload is obtained. In addition, companion flange must not be hammered on or installed with power tools.
