LUBRICATION section for details).
4. Install new Compression Springs (Items 17) and
Spring Stiffener Pins (Item 16) into the Drive Ring
(Item 10).
NOTE
The back of the Rotary Seal must be installed
facing the Drive Flange Assembly end of Torque
Limiter.
5. Install the new Rotary Seal (Item 15).
6. Lubricate the Hub spline with NEVER-SEEZ ® .
NOTE
Care must be exercised when pressing Cylinder/
Piston Assembly onto Hub and into Drive Flange
Assembly to avoid damage to the Rotary Seal.
