REAR AXLE 11 - 25<br />
18. If the micrometer reading shows that the pinion setting<br />
is incorrect (more than .002" plus or minus from the<br />
figures given) shims equaling the difference must either<br />
be added to or taken from the shim pack between the<br />
rear bearing cup and housing. Shims are available in<br />
.003", .005" and .010" thicknesses. When changing<br />
shim pack, measure each shim separately , replace pinion<br />
and pinion depth gauge and recheck before proceeding<br />
further.<br />
19. After correct pinion setting has been obtained, and with<br />
drive pinion in position, place original shims or new<br />
ones of equal thickness on shaft, measuring each shim<br />
separately.<br />
20. Install drive pinion front bearing cone and rolls and<br />
pinion using tool J-1570.<br />
27. Place bearing caps in their proper positions according to<br />
markings, and tighten bolts finger tight.<br />
28. Insert two screwdrivers between the bearing cup and the<br />
housing on the side opposite the drive gear, and move the<br />
differential and drive gear away from the pinion until the<br />
opposite bearing cu. firmly seated against housing. Mosii<br />
screwdrivers t o drive gear side, force differential and gear<br />
over until drive gear teeth contact pinion.<br />
29. From shim requirements shown by indicator reading<br />
(paragraph 8), place shims between bearing cups and<br />
housing, forcin g the m in on both sides so as to use total<br />
amount and have gear rotate with no backlash, Figure 51.<br />
21. Install companion flange, washer and nut on front end<br />
of pinion shaft and holding flange with J-2637 holding<br />
tool, tighten pinion nut to 180-220 foot pounds.<br />
22. Use scale on J-2637 holding tool and check torque<br />
required to turn pinion. Disregarding starting torque,<br />
turning torque should be from 10 to 20 inch pounds. If<br />
more or less than this, shims will have to be added to or<br />
taken from front shim pack. Shims in thicknesses of<br />
.003", .005", .010" and .030" are available.<br />
23. When proper torque is obtained, remove pinion nut and<br />
washer and take off companion flange.<br />
24. Place oil slinger and wick on pinion and Install new<br />
gasket in counter-bore at front of housing. Place new oil<br />
seal in housing and Install with rear face seated against<br />
gasket.<br />
25. ReInstall companion flange, washer an d nut, torquing<br />
nut to 180-220 foot pounds.<br />
26. Inspect differential bearing cone and rolls and cups as<br />
well as the bearing bores in the housing and be sure they<br />
are clean; place cups on rollers and lubricate ; Install<br />
differential assembly in housing<br />
FIGURE 51<br />
30. Take out differential assembly and drive gear, keeping<br />
shims for each side in a separate pack. With bearing<br />
puller, remove bearing cones from differential case and<br />
Install shim packs on their respective hubs, placing additional<br />
shims totaling .015" on the right hub to compensate<br />
for housing spread and gear tooth backlash. Install<br />
differential bearing cone and rolls on hubs, using tool<br />
J-2646 making sure hubs, bearings and shims are clean.<br />
Lubricate bearings with axle lubricant.
