9. Disassemble case. Keep the stack of plates and discs in exactly the same order in which they were removed. Inspect plates, discs, clutch rings, side gears, pinion mate gears, and pinion mate shafts for damage, scoring or wear. If any one of the plates or discs on either stack shows wear or scoring the complete stack is to be replaced on both sides. Clutch rings which show wear or scoring are also to be replaced in sets. The side gears and pinion mate gears that show damage or wear are also to be replaced in sets. If wear is indicated on the cams of the pinion mate shafts, these are also to be replaced in sets. 10. Above is a typical example of scoring and, as mentioned, all plates and discs of the Powr-Lok are to be replaced. 11. The pinion mate shafts are unlike the shaft of a conventional differential and, therefore, are not locked to the differential case.12. Notice also that at the end of each shaft, they are formed into a "V", and each case half has "V" shaped surfaces. The "V" formation of the case is known as a ramp. If wear is evident on either case half, then both halves must be replaced. 13. Some semi-float axles require a spacer block to maintain proper end play and transmit thrust forces from one axle shaft to the opposite axle shaft and its wheel bearing. There is one type spacer block and it is known as the roll pin design. Axle shafts which do not require end play have no spacer block in the cross pins. Powr-Lok Reassembly
1. Replace plates, discs, side gear and cluth ring in exactly the same position as they were removed, (unless rearrangement was required). Apply specified lubricant on each individual part. Refer to Vehicle Service Manual for the specified lubricant. 2. With the plates and discs now assembled to the side gear and cluth ring, line up the ears of the plate with the grooves in case so they will easily enter into the ring gear case half. 3. Install pinion mate shafts and pinion mate gears. Make sure the shafts correspond with the chalk as marked at time of disassembly. Refer to page 29, item 7. Install the other side gear, clutch ring, plates, and disc exactly as they were removed (unless rearrangement was required). Prelube each part. Line up ears of plates with grooves of the case. 4. Assemble button half of case, making sure chalk marks are lined up. Assemble case body screws finger tight. 5. Place case onto axle shaft as shown. Tighten body screw alternately and evenly. Torque screws to 88-95 N m (65-70 lbs. ft.). 6. Mount spreader onto housing. Locate dial indicator with a magnetic base and extensions as shown. Locate tip of indicator on housing as shown. Make sure the indicator has a minimum travel of .76 mm (.030") for this operation.Set dial indicator at zero (0). Turn forcing screw until
