wear or damage, and replace the parts as necessary.
Installing the Rotor Shaft
Refer to Figure 42 for this procedure.
1. Install the inner retaining rings into the rotor shaft grooves if they were
removed.
2. Install the bearings onto the rotor shaft by pressing on the inner race of the
bearing. Ensure that the bearings are seated against the inner retaining rings.
3. Install the outer retaining rings into the rotor shaft grooves.
4. Install a new O-ring into the rear bearing cap. Apply a thin film of oil to the
O-ring.
5. Apply medium strength thread locking compound to 4 of the flange-head
screws (item 1) and secure the center plate and rear bearing cap to the inner
housing. Tighten the screws from
10.2 to 11.3 N∙m (90 to 100 in-lb) .
6. Position the end cap (item 4) between the bearings of the rotor shaft
assembly.
7. Align the tab on the end cap with the slot in the inner housing and install the
rotor shaft assembly. Ensure that the bearings are seated in the bearing caps
and the front bearing cap is seated in the inner housing.
8. Apply medium strength thread locking compound to 4 of the flange-head
screws (item 1) and secure the end cap and front bearing cap to the inner
housing. Tighten the screws from
10.2 to 11.3 N∙m (90 to 100 in-lb) .
9. Ensure that the rotor shaft rotates freely, and correct any issues before
proceeding.
10. Install the nozzle and the nozzle clamp. Position the nozzle clamp fasteners
at the seam inside the nozzle and tighten from 4.5 to 5.5 N·m (40 to 50 in-lb) .
