REAR AXLE 28 III PINION POSITION SHIM SELECTION 1. Pinion position shim selection can also be done using a special tool, in the absence of removed ring/pinion gear. 2. Install pinion height set master block which is part of tool (Part no. 289458903504) over pinion inner bearing cup seat. 3. Set the dial gauge to 0 (zero) , on surface plate. Install dial gauge on pinion height gauge which is again a part of tool (Part no. 289458903503) 4. Install pinion height set gauge with dial gauge on side bearing seats. Ensure that plunger of dial gauge touches top face of pinion height set master. 5. Rock the depth gauge. Record the maximum reading on gauge needle. Let it be X' 6. To calculate shim thickness procedure as follows: Shim thickness required = X– etched value on pinion (when etched POSITIVE) Shim thickness required = X + etched value on pinion (when etched NEGATIVE) ASSEMBLY 1. Drive inner bearing cup into carrier using tools given below:  Installer dolly inner pinion bearing cup (Part No. 289458903508).  Handle (Part No. 289458903501) In such a way that orientation of the baffle towards the pinion oil gallery. 2. Assemble outer pinion bearing cup and baffle into carrier using tools given below:  Dolly, outer pinion bearing cup (Part No. 289458903507)  Handle (Part No. 289458903501)
