SECTION 03CHASSIS PREPARATION
Fill the shock with Bombardier HPG shock oil (PN 413 711 806) to approximately 10 mm (.393 in), from the base of seal carrier threads

1Fill to 10 mm (.393 in)
NOTE: Although we do not measure the exact amount of oil added to the damper, approximately 106 mL (3.58 oz U.S will be usedCarefully insert damper rod into the damper bodyInstall damper rod assembly into the damper bodyLightly oil damper piston seal ring with shock oil to ease installation
CAUTION: Use care when passing piston into damper body at damper body threadsSlight oscillation of damper rod may be required to allow piston to enter damper body boreSlowly push piston into damper bodySlight up and down movement may be required to allow all air to pass through piston assemblyThe gentle tapping of small wrench, on the shock eye, may help dislodge air trapped in the submersed pistonBe careful not to drive the shaft any deeper into the oil than is necessary to just cover the shim stackNOTE: Fast installation of the damper rod may displace the floating piston from its original positionThis must not occur if the damper is expected to perform as designedWith damper rod piston into-oil, TOP OFF damper oil volumeOil level should be to damper body thread baseSeal carrier assembly can now be threaded into damper bodyThis should be done slowly to allow weapage of oil and to minimize IFP displacementAfter the seal carrier is fully in place avoid pushing the shaft into the body until the nitrogen charge is added
