19. Joe used a non-metallic hammer handle to push upward on the IFP to move it up in the reservoir body. Then the reservoir end cap with Schrader valve was reinstalled with the snap ring. The reservoir was pressurized to about 10 psi. (Not all shocks have the IFP “topped out.” IFP depths vary depending on the shock. These depths can be downloaded from the FOX website.) Fresh fluid was added to the shock body and Joe worked the shaft assembly back into the body. The FOX manual details a few steps that allow complete filling of the shock oil and proper bleeding for both piggyback and non-piggyback shock types.
