User Manual

1. Thoroughly clean the dierenal case and wash re-

maining parts with solvent, then dry them.

2. Inspect the pinion sha. Any noceable grooves or

galling may weaken it and can also adversely aect the operaon

of your new LOCK-RIGHT. If it is not in excellent condion, obtain

a new one.

3. Inspect the side gear thrust washers. They are im-

portant to the correct posioning of the LOCK-RIGHT parts. If

they are excessively worn or are cracked, obtain new ones. If

several thicknesses are oered, try to obtain the same size as the

old ones. NOTE: There should be TWO thrust washers of about

equal thickness, one under each side gear.

4. Inspect the thrust block (if used). Be sure that the

ends are smooth and not galled.

5. Inspect the case for any chips, cracks or similar

damage. Also inspect the bearings, if the case is out of the

vehicle. If the case or bearings look bad, replace them. However,

if you do, remember that the shims no longer will be correct; the

ring and pinion backlash and bearings pre-load will need to be

reset with a dial indicator as described in the shop manual.

Preparing the Parts for Assembly

1. Coat the teeth of the couplers and drivers, the large

center holes of the drivers, and both sides of the thrust washers

with medium grease. Also place a lile grease in each of the two

window holes in each driver. The grease will help hold things in

place and assist with funconing unl the gear oil circulates.

2. Place a shear pin into each window hole. It should

be about ush (Figure 2).
