Pinion Depth Procedure

1. Install master pinion block. Special tool 5032, or equivalent.





2. Install arbor (D-115-3) and arbor discs (D-2364-ICA-2), or equivalents.





3. Install pinion height block. Special tool D-115-1, or equivalent.





4. Install scooter gauge. Zero the gauge on the pinion height block.
5. Slide scooter gauge over the top of the arbor. Slide scooter until highest reading is obtained. Record the number obtained. This reading indicates the thickness of the shim stack that is required to install a pinion that is etched with a zero (0) at a zero (0) position. If the pinion being installed has a plus (+) or a minus (-) etching, then an adjustment of this shim stack is required.
6. For example: If a pinion is etched +3, then this pinion would require 0.003" (0.08 mm) less shims than a pinion etched zero (0). If a pinion is etched -3, then add 0.003" (0.08 mm) more shims to the shim stack then would be required if the pinion were etched zero (0).
7. Install shim and cone onto pinion using special tool MD998805, or equivalent. Place inner pinion bearing cone on the pinion. Place the bearing installer over pinion shaft. Drive bearing onto shaft until completely seated against thrust face of pinion. Failure to use the correct special tool may cause bearing damage during installation.
