  • Re Gear Speedometer Calibration Remove Bearing Races
    A long aluminum punch was used to drive out the old pinion bearing races.
  • Re Gear Speedometer Calibration Step Plates
    Bill pulled out a set of step plates and found the matching size to drive in the new pinion bearing races.

  • Re Gear Speedometer Calibration Pinion Lube
    The new pinion was given a coat of Break Away lube before the race was pressed on.
  • Re Gear Speedometer Calibration Remove Bearings
    A special bearing puller was used to remove the bearings from the carrier.
  • Re Gear Speedometer Calibration New Ring Gear
    A 10-bolt rearend has-you guessed it-10 bolts holding the ring gear to the carrier. Bill removed them and swapped in the Sierra Gear and Axle ring gear, then bolted it back after coating the bolts with Loctite.

  • Re Gear Speedometer Calibration Install Carrier Bearings
    Back at the press, we installed the carrier bearings.
  • Re Gear Speedometer Calibration Install Pinion Yoke
    Bill bolted in the pinion gear and driveshaft yoke to begin the installation.
  • Re Gear Speedometer Calibration Trial Fitting
    The carrier went back in with the original shims, but it was too tight, so Bill removed one of the .001-inch shims and began the trial fitting.

  • Re Gear Speedometer Calibration Check Backlash
    With the bearing caps reinstalled, the first check was backlash. The .010 inch of backlash measured fell within the specs for a 10-bolt.

  • Re Gear Speedometer Calibration Pinion Contact
    Marking paint was applied to the ring gear to check the contact patch with the pinion.
  • Re Gear Speedometer Calibration Swap Shims
    The first try showed that the contact patch was too shallow, so Bill swapped shims to move the ring gear .005 inches to the pinion side of the axle.
