Differential Gear Installation 1. If the ring gear was removed, use medium strength thread locking compound and tighten the mounting screws from 22 to 25 ft-lb (30 to 34 N -m). 1 2 3 2. Apply molybdenum disulfide grease to the splines and bearing surfaces of the differential pinion gears, pinion washers and side gears. 3. Install the side gear shims and side gears in their original location in the differential case. 4. Place the differential pinion gears and pinion washers in their original location in the differential case. Temporarily install the differential pinion shaft. 5. Secure the differential case in a vise. Position a dial indicator at the tooths center and measure the differential pinion gear to side gear backlash (Fig. 39). PINION GEAR TO SIDE GEAR BACKLASH: 0.004 to 0.016 in. (0.10 to 0.40 mm) 1. Vise 2. Differential gear case More than 35% total tooth contact Figure 39 3. Dial indicator 6. Adjust backlash by increasing or reducing side gear shim thickness. NOTE: Side gear shims are available in 0.043 in. (1.1 mm), 0.047 in. (1.2 mm) and 0.051 in. (1.3 mm) thickness. 7. Apply gear marking compound, such as DyKemR Steel Blue lightly over several gear teeth. 8. While applying a light load to either side gear, rotate either pinion gear until the side gears have made one complete revolution. 9. Ideal tooth contact should cover more than 35% of each tooth surface. The contact area should be in the center of each tooth and extend 1/3 to 1/2 way across each tooth from the toe (small) end (Fig. 40). 10.Adjust side gear shims if necessary to correct tooth contact. Recheck differential pinion gear to side gear backlash if any changes are made. 11.After backlash and tooth contact have been adjusted, align the hole in the differential pinion shaft with the hole in the differential case and install a new spring pin. 1/3 to 1/2 of entire width from small end of tooth Figure 40 12.Install differential gear assembly in right side axle support half. 13.Coat a new O-ring with grease and install left side axle support half. Tighten axle support case screws from 35 to 41 ft-lb (47 to 56 N -m). 14.Install input shaft/pinion gear assembly (see Input shaft/Pinion in this section of this manual). 15.Coat new O-rings with grease, align differential shaft splines with differential gear assembly and slide differential shaft assemblies onto axle support. 16.Install bevel gear case/axle case assemblies (see Bevel Gear Case/Axle Case Assembly in this section of this manual).

Pinion Gear to Ring Gear Engagement The final position of the pinion gear is verified by using the gear contact pattern method as described in the following procedure. GEAR TOOTH DEFINITIONS (Fig. 41): TOP LAND PROFILE Toe -- the portion of the tooth surface at the end towards the center. Heel -- the portion of the gear tooth at the outer end. Top Land -- top surface of tooth. TOE HEEL LENGTHWISE BEARING ARC 1. Paint the teeth of the ring gear, both drive and coast side, with a gear marking compound, such as DyKemR Steel Blue. 2. Install the input shaft/pinion gear assembly into axle case. 3. While applying a light load to the ring gear, rotate the pinion gear in the direction of forward travel until the ring gear has made one complete revolution. Ideal tooth contact observed on the ring gear should cover more than 35% of each tooth surface. The contact area should be in the center of each tooth and extend 1/3 to 1/2 way across each tooth from the toe end (Fig. 42). ROOT Figure 41 More than 35% total tooth contact 1/3 to 1/2 of entire width from small end of tooth Adjustments to the gear contact position are made by moving the input shaft/pinion gear (bearing case shims) or by moving the differential gear case (differential bearing shims) (Fig. 43). NOTE: Bearing case shims are available in 0.004 in. (0.10 mm) and 0.008 in. (0.20 mm) thickness. NOTE: Differential bearing shims are available in 0.004 in. (0.10 mm), 0.008 in. (0.20 mm) and 0.016 in. (0.40 mm) thickness. 4 3 Figure 42 Axles, Planetaries and Brakes Study the different contact patterns (Figs. 44 and 45) and correct gear engagement as necessary. NOTE: When making changes, note that two variables are involved (see Gear Pattern Movement Summary in this section of this manual). 2 1 Example: If the pinion gear to ring gear backlash is set correctly to specifications and the bearing case shim is changed to adjust tooth contact, it may be necessary to readjust backlash to the correct specification before checking the contact pattern. 1.
