Before starting the assembly procedure, perform the following steps to adjust dimensional differences (clutch plate friction force) in the axial direction of the components inside the differential case and axial clearance of the differential side gear.
Scheme 86
Scheme 87
- Place friction discs (two each) and friction plates (three each) one on top of another as illustrated and, using a micrometer, measure the thickness of each of the right and left assemblies. Select different discs and plates so that the difference between the right and left assemblies falls within the specified range. Standard value: 0 - 0.05 mm (0 - 0.002 inch) NOTE: If a new part is used, note that the friction disc comes in two thickness: 1.6 mm (0.063 inch) and 1.7 mm (0.067 inch).
- Measure the thickness of each of the right and left spring plates.
- Assemble the pressure ring internal parts (pinion shaft and pressure ring), friction plates, and friction discs and, using a micrometer, measure the overall width. NOTE: When taking measurements, press the assembly from both sides so that the pinion shaft makes a positive contact with the groove in the pressure ring.
- Find value (A) which is the thickness measured in step (3) added to the thickness of two spring plates.
- Find dimension (B) between the spring plate facing surfaces when differential case A and B are assembled together. B = C + D - E
- If the clearance between the spring plate and differential case (B - A) is outside the specified range, change the friction discs and make adjustments. Standard value: 0.06 - 0.25 mm (0.002 - 0.010 inch)
- Coat each part with the specified gear oil and mount it in the specified direction and order into differential case B. Hypoid gear oil MITSUBISHI Genuine Gear Oil Part No. 8149630 EX, or equivalent NOTE: Apply a careful coat of gear oil to the contacting and sliding surfaces.
Scheme 88
Scheme 89
- Align the alignment mark on differential case A with that on differential case B.
- Tighten the screws connecting differential case A and B a uniform amount little by little in the diagonal order. NOTE: If tightening the screws does not bring the two cases properly together, spring plates are not probably assembled properly. Reassemble from the start.
Scheme 90
Scheme 91
- Use special tools MB990989 and MB990990 to check for differential torque. Standard value: NOTE: Before measuring the differential torque, first turn the gears so they snug each other, then take measurements during rotation.
- If the measurement falls outside the specified range, disassemble the differential case assembly and repair or replace defective parts.
Scheme 92
- Clean the disassembled parts with cleaning oil and dry them with compressed air.
- Check each plate, disc, and pressure ring for the following: A: Friction and sliding surfaces of friction discs, friction plates, and spring plates. Replace a defective part with heat discoloration and excessive wear with a new one, as it degrades locking performance. NOTE: If the inner periphery of the friction face shows traces of harsh contact, it is because of the spring tension of each plate, disc and other part. Do not confuse this with abnormal wear. B: Inner periphery and outer periphery protrusions of friction discs, friction plates, and spring plates. Replace a cracked or damaged part with a new one. C: Friction and sliding surfaces between pressure rings and friction discs. Grind a dented or scratched part with oil stone and then lap and correct with a compound on a surface plate. NOTE: If the inner periphery of the friction face shows traces of harsh contact, it is because of the spring tension of each plate, disc and other part. Do not confuse this with abnormal wear.
- Check the following parts for contact and siding surfaces (D to M) and correct burrs and dents with oil stone. D: Sliding surfaces of side gear and case E: Contacting surfaces of differential case and spring plate F: Contacting surfaces of pressure ring and differential case inner face G: Sliding surfaces of pressure ring hole and side gear H: Protrusions on outer periphery of pressure ring I: Pressure ring inner surface and differential pinion gear spherical surface J: Pressure ring V-groove and pinion shaft V K: Sliding surfaces of pinion shaft and differential pinion gear hole L: Side gear grooves on outer periphery M: Slits in inner periphery of differential
