IMPORTANT
If your dierenal case or thrust washers are excessively worn, your new
LOCK-RIGHT Locker may not be able to operate as it was designed. Therefore, two easy
measurements must be made before nal assembly to assure that your new locker will
funcon properly. To make these measurements, proceed as follows:
1. Remove the exisng spider gears, side gears and thrust washers from the
dierenal case, and thoroughly clean it.
2. Install the LOCK-RIGHT couplers with the exisng thrust washers in each end
of the case.
3. Place the spacers onto the centers of the couplers (wide side toward the axle splines if not symmetrical), and hold them
there.
4. Install the pinion sha; carefully guide it past the spacers as it is being inserted through the holes in the case.
5. Measure the gap between each spacer and the pinion sha with a feeler gauge. This gap should be between .005-inch
and .020-inch, with not more than an .008-inch dierence between the two.
If your numbers are within the limits specied, remove the parts and begin your installaon. If your numbers are not within
these limits, check the thrust washers and the dierenal case. If they are excessively worn or are damaged, they may need to be
replaced before installing your new Lock-Right Locker.
