8. Apply lubricant to the differential pinion shaft,thrust washers, differential pinions and sidegears. To obtain this lubricant, see the ServiceNotes page on the front inside cover ofthis manual.9. Install the thrust washer and side gear intothe differential case. Figure 4.12.10. Slide the differential pinions and thrust washersonto the differential pinion shaft. . Figure4.13.11. Position the differential pinion shaft in thedifferential case on top of the side gear. Figure4.14.12. Install the side gear and thrust washer overthe differential pinions. Figure 4.15.13. Position the case half over the side gear.Figure 4.161 - CROSS HEADAssembly and InstallationFigure 4.141 - SIDE GEAR2 - THRUST WASHERFigure 4.151 - SIDE GEAR2 - THRUST WASHERFigure 4,12Figure 4.161 - DIFFERENTIAL PINION2 - THRUST WASHER3 - DIFFERENTIAL PINION SHAFTFigure 4.13MAINTENANCE MANUAL25
Assembly and Installation14. Install the capscrews through both differentialcase halves and into the ring gear.Use a CRISSCROSS pattern to tighten thecapscrews shown below:1. For screws M12, apply toque angle of 37 +7/-0 Lb. (50 + 10 /-0 N.m + 60º + 10º / -0º)2. For screws M14, apply toque angle of 63 +4/-0 Lb. (85 + 5 /-0 N.m + 60º + 5º / -0º)15. Inspect the differential gears rotating resistance.Use the following procedure2. Place the differential and ring gear assemblyin a vise. Install soft metal covers over thevise jaws to protect the ring gear.3. Install the tool into the differential until thespines on the tool are engaged with one sidegear.4. Place a torque wrench onto the nut onto thetool and rotate the differential gears. Readthe value indicated on the torque wrench.• If the torque value is greater than 50 lb-ft (68N.m): Disassemble the differential case andinspect parts for wear or damage. Repair orreplace parts as necessary. Reassemble thedifferential case and repeat Steps 2 through4.InstallationPinion Cage onto the Differential1 - CAPSCREWSFigure 4.17Differential Gears Rotating Resistance1. Make an inspection tool using an axle shaftthat matches the spline size of the differentialside gear. Cut the shaft to approximately12-inches (304.8 mm). Weld a nut onto theend of the shaft. Figure 4.18.1. Place the pinion cage onto the differential.Use your hands to screw the pinion cage intothe differential to verify that the cage is correctlyinstalled.2. Install the Fork locknut onto the drive pinionshaft. Do not install the Fork at this time.3. Use appropriate tools to screw the pinioncage into the differential while rotating the pinionto seat the bearings.4. Tighten the pinion cage to adjust the drive pinionbearing preload. Check the preload byrotating the pinion by the Fork locknut withatorque wrench. Figure 4.19. The correct torqueis 5-20 lb.-in (5.8-23 N.m).5. Position the pinion cage lock plate. Figure4.20.• If the lock plate does not match one of thefour possible positions: Tighten the pinioncage while checking the preload to keep it withinspecification.6. Install the capscrews and tighten them to 10-13 lb-ft (14-18 N•m). Remove the Fork locknut.1 - APROXIMATELY 12” (305 mm)2 - SIDE VIEW3 - WELD NUT TO END OF SHAFT4 - END VIEWFigure 4.1826 MAINTENANCE MANUAL
