Without the gearbox cover spacers may be required to
ensure the casing is fully clamped in position
NOTE:

4.1.2 ROllING TORQUE /
PRE-lOad
Use a torque meter to check the rolling torque see section 6.2
for torque settings.
If the rolling torque is under / over the required amount add /
remove shims to adjust the pre-load to suit (See section 6.2
Fasteners & Torque Settings).
NOTE:
Rolling torque can only be set on new bearings, with no
sealing devices installed i.e. lip-seals or O-rings.
When checking the rolling torque is it important to make sure
the shaft is rotating freely, completely rotate the shaft 10 times
before checking the rolling torque.
The pre-load is set by adding or removing shims in position A
(See Figure 25).
Install 0.25 mm (0.009”) of shims (5.13) , pre-load spacer
(5.05), gear (5.06) and locknut (5.09)
NOTE:
Do not install the gear key or tab washer at this time
When setting the pre-load on the shafts note the pre-load has to
be set on individual shafts, so only install one gear at a time.
