nect the negative battery cable from the battery termi-
nal. Position disconnected negative cable away from
the negative battery terminal.

(Fig. 3).
4. Remove cap screws, flat washers and lock nuts that
secure drive shaft assembly to hubs on engine shaft and
blower shaft.
5. Lift drive shaft assembly from machine.
6. Disassemble drive couplings from drive shaft using
Figures 1 and 2 as guides. Note differences in coupling
spacer flange thickness for assembly purposes.
7. Inspect drive couplings for damage and replace if
necessary.
8. If necessary, remove hubs from engine shaft and
blower shaft:
A. Remove cap screw and flat washer that secure
hub to shaft.
NOTE: Hub has a tapered ID and will require a puller
to remove it from shaft.
B. Use appropriate puller to remove hub from shaft.
C. Remove woodruff key from shaft slot.
Installation (Fig. 1)
1. If hub was removed from engine shaft or blower
shaft, thoroughly clean tapers of shaft(s) and hub(s). Fit
