Pinion Bearing Preload

  1. Clean exterior of steering gear thoroughly and mount gear in a soft-jawed vise or suitable holding fixture.
  2. Loosen yoke cover bolts to relieve spring pressure on rack. Remove pinion cover and clean cover flange area thoroughly, then remove cover gasket, spacer and shims.
  3. Install new gasket on pinion cover flange, fit shims between upper bearing and spacer until shim pack is flush with top surface of gasket (check with light pressure on straightedge placed on gasket face), then add one 0.005" shim to preload bearings.
    NOTE: Spacer must be assembled next to housing cover.
