Drive Pinion Gear

  1. Install front and rear bearing races in housing. Press rear bearing onto drive pinion. Note any deviations ("+" or "-") stamped on drive pinion. This amount must be added (if "+") or subtracted (if "-") from measurement "C". See Fig 1.
  2. If original ring and pinion gear set is being installed, install drive pinion gear using original shim and new collapsible spacer. If new ring and pinion gear set is being installed, install new shim that is same thickness as original shim.
