Section 07 REAR SUSPENSION Subsection 03 (SC-10 III SUSPENSION)
Slowly push piston into damper bodySlight up and down movement may be required on short stroke 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 displacementTorque seal carrier to 90 to 100 Nm (66 to 74 lbfft)After the seal carrier is fully in place avoid pushing the shaft into the body until the nitrogen charge is added
Adding Gas Pressure Nitrogen (N2) can now be added to damper body1
