286 Differential

NOTES:
- The 286 RBI Trac-Lok differential has a one-piece cross shaft and uses 6 disc and 5 plates for each clutch pack. Only one disc in each clutch pack is dished.

- Pay close attention to the clutch pack arrangement during this procedure. Note the direction of the concave and convex side of the plates and discs.





DISASSEMBLY
1. Mark the ring gear half and cover half for installation reference.





2. Remove the case attaching bolts and remove the button cover half.





3. Remove top clutch pack.
4. Remove top side gear clutch ring.
5. Remove top side gear.
6. Remove pinion mate gears and cross shaft.
7. Remove the same parts listed above from the ring gear flange half of the case. Keep these parts with the flange cover half for correct installation in their original positions.

NOTE: The clutch discs are replaceable as complete sets only. If one clutch disc pack is damaged, both packs must be replaced. Lubricate each component with gear lube before assembly and installation.





ASSEMBLY
1. Saturate the clutch plates with MOPAR Hypoid Gear Lubricant or Additive. Assemble clutch packs into the side gear plate in exactly the same position as removed.





2. Line up the plate ears and install the assembled pack into the flange half. Make sure the clutch plate lugs enter the slots in the case. Also make sure the clutch pack bottoms out on the case.





3. Install pinion mate shafts and pinion mate gears. Make sure shafts are correctly installed according to the alignment marks.
4. Lubricate and install the other side gear and clutch pack.
5. Correctly align and assemble button half to flange half. Install case body screws finger tight.





6. Tighten body screws alternately and evenly. Tighten screws to 89 - 94 Nm (65 - 70 ft. lbs.) torque. If bolt heads have 7 radial lines or the number 180 stamped on the head, tighten these bolts to 122 - 136 Nm (90 - 100 ft. lbs.) torque.
