NOTE: The rotor shaft and bearings can be serviced
without removing inner housing from machine.
NOTE: Several changes were made to the rotor shaft
assembly above machine serial number 310000000.
Figure 6 shows both the earlier and later illustration for
the inner housing assembly used on machines with seri-
al number below 313000000.
NOTE: If inner housing has been replaced by a later
housing version, use appropriate illustration and service
procedures. Rotor shaft for machines with serial number
above 313000000 is described later in this section.
Removal (Fig. 6)
1. Position machine on a firm, level surface. Make sure
engine is stopped and remove key from the ignition
switch. Chock wheels to prevent machine from moving.
2. To prevent unexpected machine operation, discon-
nect the negative battery cable from the battery terminal
(see Battery Service in the Service and Repairs section
of Chapter 4 -- Electrical System). Position discon-
nected negative cable away from the negative battery
terminal.
3. Remove nozzle and nozzle pulley from rear of outer
housing (see Nozzle Assembly Removal in this section).
