STEERING / SUSPENSION

16. Slowly cycle the IFP up and down. 20. Add oil to the body tube until the surface of the oil is
at the top of the shock body threads.
• Be sure to bottom out piston in the reservoir body.
• Allow time for the bubbles to dissipate.
• Repeat the process until all air has been removed.

17. Pull IFP up until its top is approximately 1" (2.54 cm)
from top of reservoir and remove the IFP Tool. Using
a 3/32" Allen wrench, install the IFP bleed screw.

NOTICE
During installation, some shock oil will over flow. Wrap
a shop cloth around the shock body to catch any oil
overflow.

21. Pull the damping piston up until it is just below the
surface of the oil.

surface of the oil during this process.
• While holding the shock rod, apply 2 - 3 sharp blows to
the rod eyelet with a rubber mallet driving the piston
down into the shock body. This opens the valves on
the damping piston. You will see the released air
bubbles come to the surface of the oil.
