When making adjustments, ensure there is no gear interference from other components.
1.
Using tool L-4656 and handle C-4171, press input shaft front bearing cup slightly forward in case. Using tool L-4655 and handle C-4171, press
bearing back into case from the front to properly seat bearing cup.
2.
Select a suitable gauging shim that will give 0.001-0.010 inch endplay. If original shim is available, measure it, then select a shim 0.010 inch
less than measurement.
3.
Install gauging shim on bearing cup, then install shaft seal retainer. Alternately tighten input shaft seal retainer attaching bolts until snug, then
torque to 21 ft. lbs.
4.
Lubricate input shaft bearings with SAE 5W-30 motor oil, then install input shaft in case. Install bearing retainer plate with input shaft rear bearing
cup pressed in and bearing support plate installed. Torque attaching bolts to 21 ft. lbs.
5.
Position suitable dial indicator inside case in such a way as to measure input shaft endplay. Apply moderate load by hand to input shaft splines.
Push input shaft towards rear while rotating back and forth several times to seat bearings. Zero dial indicator, then pull input shaft forward as far as
possible while rotating several times to seat bearings. Measure and record input shaft endplay.
6.
To determine proper shim, add gauging shim thickness to endplay measurement, then subtract standard endplay measurement of 0.002 inch. After
determining proper thickness, refer to the chart for shim selection. Shims can be combined as necessary to be within 0.0016 inch of required
dimension.
7.
Remove input shaft seal retainer and gauging shim. Install shim(s) selected in step 6 above and input shaft seal retainer. Put a 1/16 inch bead of
RTV around seal retainer.
8.
Alternately torque input shaft retainer attaching bolts to 21 ft. lbs.
9.
Using a suitable inch lb. torque wrench, measure input shaft turning torque. Turning torque should be 1-5 inch lbs. for new bearings or at least 1
inch lb. for used bearings. If turning torque is too high, install a 0.0016 inch thinner shim. If turning torque is too low, install a 0.0016 inch thicker
