Removing the Rotor Assembly (continued)
Note: The rotor assembly components are not available separately. If rotor
damage occurs, replace the complete rotor assembly.
Installing the Rotor Assembly
Refer to Figure 40 for the for this procedure.
Note: Washers (item 10) are used to prevent the rotor from contacting the
rotor housing assembly. Typically, 2 washers are necessary.
1. Install the same number of washers previously removed from the rotor shaft.
2. Position the woodruff key in the slot in the rotor shaft. Slide the rotor assembly
and spacer onto the rotor shaft. Ensure that the rotor does not contact the
inner rotor housing. If necessary, add an additional washer to gain clearance.
3. Slide a new inner tab washer (larger outer diameter) and then the outer tab
washer onto the rotor shaft.
IMPORTANT
The nut used to secure the rotor assembly to the rotor shaft has
left-hand threads. Tighten the nut by rotating it counterclockwise.
4. Use the 1-1/4 inch flats provided to hold the rotor shaft and install the hex nut
(item 4). Use an offset wrench to tighten the hex nut from 258 to 284 N∙m
(190 to 210 ft-lb) ; refer to Offset Wrench (page 2–13) .
5. Lock the hex nut in position by bending the inner tab washer over the outer
tab washer and one of the hex nut flats.
