7. Fill seal with grease and install it on pivot arm

pin.

8. Install washer and start new nut on pivot arm

pin.

9. Use a torque wrench and continue to tighten nut.

Note torque reading while advancing lower cone

to its seated position.

You will notice an

increase in the torque when the lower cone

starts to seat. Continue to tighten nut until

torque is 15-25 lb-ft greater than previously

noted before lower cone started to seat.

10. Check rotational bearing torque. Rotate pivot

arm back and forth several times and take rolling

torque reading. It should require 15-25 lb-ft

torque to rotate pivot arm in either direction.

NOTE

Tie rods must not be connected to

pivot am whenever rolling torque is

checked.

11. If rolling torque is less than 15 lb-in, tighten nut

an additional 5 lb-ft torque and repeat Step 10.

12. If rolling torque exceeds 25 lb-in, back nut off

one full turn. Strike end of pivot arm pin with a

softheaded mallet to unseat bearings and repeat
