Fig. 63:

6. Set up dial indicator as shown in (Fig. 63).
7. Zero the dial indicator and then push up on the input shaft. Record the end play reading obtained. If there is no end play recorded, a thinner shim must be installed behind the bearing cone in the front adapter. Install 0.010 inch thinner shims until an end play reading can be read.
8. Once an end play reading is obtained, add 0.002 inch to the reading recorded in Step 7.
9. Add the number obtained in Step 8 to the thickness of the shim that was in the transmission when the end play readings were taken. Record this number.
10. Install a shim(s) behind the bearing cone in the front adapter equal to the number recorded in Step 9.
