NOTE: Pinion depth measurement is taken with the pinion head and tail bearing cups pressed into the axle housing without the shim.






NOTE: Do not attempt to install the inner and outer pinion bearing cups at the same time.

1. If necessary, install the pinion head bearing cup into housing with Pinion Bearing Cup Installer (1).

7. Zero Dial Indicator (1) on L-block (2).





8. Slide indicator probe (1) off of height block and onto Arbor Bar (2). As indicator contacts Arbor Bar (2), indicator needle will rotate clockwise. Continue moving indicator probe to the crest of Arbor Bar and record the highest reading.
