- Install spacers (5.17), tab washers (5.20) and lock nuts
(5.14) to shafts (5.01 and 5.02) tightening to correct torque,
refer to section 8.2. Secure tab washers.
- Install bearing (6.02) inner races to shafts (5.01 and 5.02)
positioning against shoulder on shaft.
- Install bearing (6.02) outer races and retaining rings (6.01) to
gearbox (4.01).
- Install two bearing cups (5.05) to gearbox (4.01).
- Support gearbox (4.01) in a vertical position and install shafts
(5.01 and 5.02) to gearbox (4.01).
- Install remaining bearing cups (5.05), shims (5.04) to nominal
value of 0.6mm (0.024”), O-rings (5.21), retainers (5.06) and
secure with screws (5.07) tightening to correct torque, refer
to section 8.2.
- Using a torque wrench, check rolling torque of each shaft
assembly, refer to section 8.2, if necessary adjust amount of
shim (5.04) either by adding shim (5.04) to increase rolling
torque or removing shim (5.04) to decrease rolling torque until
correct rolling torque has been achieved. If shim is adjusted
ensure screws (5.07) are tightened to correct torque before
final check of rolling torque.
- Install rotors (2.01) onto shafts (5.01 and 5.02) with rotor
retainers (2.02).
Note: The socket tool (not shown) should
always be used to remove the retainer. The
use of other tools may damage the retainer.
- Using a depth micrometer or similar device measure any
difference (X) in rotor front face alignment, see Figure 35. If
a difference is found move shims (5.04) of thickness equal
to the difference (X) from beneath the lower rotors bearing
retainer (5.06) and reposition under the front bearing
(5.05) cup.
- Remove lock nut (5.12) and tab washer (5.11).
- Remove timing gears (5.0-
