IMPORTANT
If your differential 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 final assembly to assure that your new locker will
function properly. To make these measurements, proceed as follows:
1. Remove the existing spider gears, side gears and thrust washers from the
differential case, and thoroughly clean it.
2. Install the LOCK-RIGHT couplers with the existing 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 shaft; 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 shaft with a feeler gauge. This gap should be between .005-inch
and .020-inch, with not more than an .008-inch difference between the two.
If your numbers are within the limits specified, remove the parts and begin your installation. If your numbers are not within
these limits, check the thrust washers and the differential case. If they are excessively worn or are damaged, they may need to be
replaced before installing your new Lock-Right Locker.
