INSTALLATION - Continued
NOTE
Ensure correct shim packs are with trunnion and bearing assemblies.
10.
Install lower shim packs (Figure 6, Item 5).
CAUTION
DO NOT tighten bolts at this time. Damage to axle could result.
11.
Install tie rod lever (Figure 6, Item 4) and four bolts (Figure 6, Item 1) to pivot and spindle assembly
(Figure 6, Item 3).
NOTE
If axle housing, pivot and spindle assembly, or trunnion assemblies have been replaced,
shimming must be checked and a preload check must be made. If not, go to Step 13.
12.
Perform the following procedures to determine the required upper shimming:
a.
Install all shims (Figure 6, Item 5) supplied in shim kit.
b.
Install pivot cap (Figure 6, Item 2) and bolts (Figure 6, Item 1). Tighten bolts in diagonal pattern to
30 ft-lb (41 Nm), then retighten them in the same pattern, increasing the torque in 2 ft-lb (2.7 Nm)
increments until all have been tightened to 35 ft-lb (47 Nm).
c.
Move pivot cup (Figure 6, Item 2) through 5 to 10 complete turns to seat bearing.
d.
Using the procedure from Step b, re-tighten bolts (Figure 6, Item 1) to 35 ft-lb (47 Nm).
e.
Using a feeler gage, measure the gap between pivot and spindle assembly (Figure 6, Item 3) and
pivot cap (Figure 6, Item 2) on all four sides.
f.
The average of the gaps is the amount to be subtracted from shim kit to obtain upper shim
pack (Figure 6, Item 5).
g.
Remove bolts (Figure 6, Item 1), pivot cap (Figure 6, Item 2), and shim (Figure 6, Item 5).
13.
Install shim pack (Figure 6, Item 5) onto upper trunnion/bearing assembly.
14.
Apply grease to bore of pivot cap (Figure 6, Item 2) and snug pivot cap to pivot and spindle assembly
(Figure 6, Item 3) with bolts (Figure 6, Item 1).
15.
Tighten all bolts (Figure 6, Item 1) to 542 ft-lb (735 Nm).
16.
Install pivot and spindle assembly (Figure 6, Item 3).
