OVERHAUL
6. Remove wire from around intermediate gears.
7. Rotate intermediate shaft until retaining plate
can be located on flat on shaft.
8. Apply Loctite 290 to threads of retaining plate
bolt.
9. Fit bolt and tighten to 25 Nm (18 lbf.ft).
10. Fit a new intermediate shaft nut.
11. Tighten intermediate shaft nut in small stages
until all end-float is just removed from
intermediate gears.
CAUTION: Check end-float of intermediate
gears between each stage, do not
continue tightening nut after end-float is
removed. Do not stake nut at this stage.
12. Set intermediate gear bearing pre-load
- See
Intermediate gear bearing pre-load.
Intermediate gear bearing pre-load
1. Select neutral.
2. Screw a suitable bolt into tapped hole in end of
tool LRT-41-005.
3. Insert tool LRT-41-005 in end of mainshaft.
4. Using a suitable torque meter on tool
LRT-41-005, check and record torque to turn
mainshaft input gears.
5. Tighten the intermediate shaft nut in small
stages checking the torque to turn the gears
until the mainshaft input gear torque to turn
figure recorded in operation 4 has increased by
1.25 Nm (10 lbf.in ).
CAUTION: Take great care not to
overtighten nut as this will cause
excessive bearing pre-load. If torque to
turn figure is inadvertently exceeded, a new
collapsible spacer must be fitted.
