OVERHAUL
11. Position front output housing as shown.
12. Up to serial no. 288709E: Position a new
gasket, dry, on front output housing.
13. Position depth block, tool LRT-41-014/2 and
cross-bar, tool LRT-41-014/1 on front output
housing.
14. Position DTI LRT-99-006 on cross-bar
LRT-41-014/1 .
15. Zero DTI on depth block LRT-41-014/2.
16. Position DTI to cross-bar LRT-41-014/1, record
reading obtained.
17. Remove tools.
18. Up to serial no. 288709E: Remove and retain
gasket.
19. Using the formula:
3.05 mm (0.120 in) + B - A = D where:
B = Height difference recorded between depth
block and cross bar
A = Average of readings to differential front
bearing outer track
D = Thickness of shim required to give
differential bearing pre-load of 0.05 mm (0.002
in)
20. From resultant figure obtained, select
appropriate thickness shim from the range
available.
NOTE: Shims are available from 2.00 to
3.25 mm (0.08 to 0.13 in) thickness rising
in increments of 0.05 mm (0.002 in).
21. Retain selected shim and differential front
bearing outer track with front output housing.
22. Up to serial no. 288709E: Retain gasket with
front output housing.
23. Carry out assembly of front output housing -
