Shocks 11After few minutes, slowly and carefully pump the shock body up and down to force the oil through the valves stacks and piston orificesContinue until air bubbles no longer rise to the surface of the oil12After removing all of the air from the shock oil, collapse the shock rod into the shock body13Remove the bleed screw from the IFPInstall new o-ring and wearband onto the IFPLubricate the assembly with shock oil14Set the depth of the IFP locator tool, PN 2871351, with Vernier CaliperThe IFP depth specifications are noted for all rebuildable shocks in this chapter15Slowly push the IFP down into the shock body until the IFP locator tool bottoms-out on the tubeTap on the shock body to remove any air trapped under the IFPNOTE: The IFP must be completely submerged in shock oil to ensure air does not become trapped under the IFP16With the IFP correctly set inside the tube, install the IFP bleed screwMake sure not to move the shock rod after installing the screw as doing so will move the IFP17Remove the shock from the bench vise and pour out the remaining shock oil into suitable container18Install the body cap onto the shock bodyTighten securely19Reinstall the fill portCharge the shock with nitrogen to the specified pressure using the gas fill tool, PN PS45259The shock rod should be pushed outwards as the IFP compresses the shock oil20Remove the fill tool from the fill port and reinstall the bleed screw21Test shock by pushing down on the shock rodThe rod should extend slowly after pushing it into the tube with no sound of trapped air inside the oilIf the sound of air is present or the rate of shock rod compression or extension dramatically changes, the shock should be disassembled and the oil replaced
