Dana Model S130 Conventional Wheel Differential Assembly, Disassembled View: Disassembly

All axles 

1. Using the Transmission Holding Fixture, mount the carrier housing.

2. NOTE: If reusing the differential ring gear and pinion, measure and record the backlash before disassembly. Assembling the differential ring gear and pinion to the recorded backlash will match the established wear patterns. Hand-rolled patterns will cover less area than the established patterns.

   Using the Dial Indicator Gauge with Holding Fixture, measure and record the differential ring gear and pinion backlash.

   • Check the backlash in 4 equally spaced positions around the differential ring gear.
   • The tooth contact pattern can move only by adjusting backlash. The tooth contact pattern can move only in the direction of heel-to-toe and toe-to-heel. Depth of the tooth contact pattern is not adjustable. Contact Spicer Service at 1-800-826-4357 for assistance if unable to establish an acceptable tooth contact pattern within the limits of backlash.

12. Place the differential assembly in a suitable press supported on the ring gear.
13. NOTE: The differential case will fall after separation. Support the case so it will not result in damage to the component or equipment.
    NOTE: It should not require more than 3 tons of press load to separate the ring gear from the differential case.
    NOTE: It may be necessary to press in more than one position to free the ring gear from the case.

    The press arbor will push on the differential ring gear bolt to separate the ring gear half of the differential from the cross shaft half of the assembly.

14. NOTE: Discard the anti-lock speed sensor ring if separating it from the ring gear side case half.

    If necessary, remove the anti-lock speed sensor ring.

15. NOTE: Alkaline cleaning solutions will damage machine surfaces. Use only emulsion cleaners or petroleum-based cleaning solvents.
    NOTE: Use soft, clean, lintless towels to dry the components.
    NOTE: After drying, lightly coat the parts with rust inhibitor or clean lubricant to prevent damage from corrosion. Wrap all parts that are going to be in storage for a prolonged period in wax paper.
    NOTE: For Truetrac® differentials, submerge the entire differential assembly in a suitable solvent to wash away contaminants from within the housing.

    Clean and dry the components.

16. The Truetrac® differential assembly is non-repairable. Discard the entire assembly if it is worn or damaged.
