Drive Pinion Bearing Depth

Install NEW drive pinion inner bearing onto appropriate aligning adapter and gauge disc. See PINION DEPTH GAUGE TOOLS table. See Figure. Install pinion outer bearing (new or used) into outer race in housing. Place gauge assembly into housing, with Screw (205-160) extending through outer bearing.

⁽¹⁾	Complete tool set is Pinion Depth Gauge Set (205-S156).

Finger tighten appropriate handle onto screw. Using 3/8" torque wrench in square drive on handle, tighten handle until preload on bearings is 20-40 INCH lbs. (2.26-4.52 N.m). Center appropriate gauge tube in side bearing bore. Install side bearing caps and tighten bolts to specification. See TORQUE SPECIFICATIONS .
Place Gauge Block (205-159) on top of drive pinion face underneath gauge tube. Using feeler gauge, determine clearance between gauge block and gauge tube. Correct feeler gauge will give slight drag feeling as gauge strip passes between tube and block.

NOTE: New pinion bearings used during depth measurement procedure must be used during final assembly in order for drive pinion depth to be correct. New oil slinger and/or baffle (if used) is measured as part of shim pack.

Thickness of feeler gauge is thickness of shim pack to be installed under inner bearing race, when drive pinion has no number marked on face. If drive pinion has a plus (+) number marked on face, subtract that number from thickness dimension. If drive pinion has a minus (-) number marked on face, add that number to thickness dimension.
Remove drive pinion inner bearing outer race from axle housing bore. Install shim pack with baffle (if used) into housing bearing bore. Reinstall inner bearing outer race into axle housing.
Using Axle Bearing/Seal Plate (205-092), arbor press and appropriate axle bearing/seal replacer, press drive pinion inner bearing and oil slinger (if used) onto the drive pinion.
