13. Using a 3/32" Allen wrench, remove IFP bleed screw.
14. Apply a thin film of oil to IFP O-ring and wear band.
Insert IFP into reservoir until completely submerged.
Allow air to escape as you install the piston.
15. Screw IFP Tool (PS-45908) onto the floating piston.

16. Slowly cycle the IFP up and down.
• 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.
NOTE
When the IFP Tool is removed, the IFP must remain
submerged in shock oil to prevent air from getting under
the floating piston.
18. Fill the shock body with oil approximately 1/4" below
the threads.
19. Apply a thin film of oil to the wear band on the
damping piston. Slowly insert the shock rod
assembly into the body until the damping piston
assembly is approximately 1" below the oil surface.
• Move rod up and down slowly over a range of about 1"
until no air bubbles rise from damping piston. Be
careful to keep damping piston at least 1/4" below the
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.
