7. Loosen cap screws and flange nuts that secure belt
guard (item 13), route v--belt from behind guard and
carefully remove belt from machine.
8. If necessary, remove nozzle guides, pulley bearings
and nozzle pulley from outer housing using Figures 9
and 12 as guides.
Installation (Fig. 9)
1. If removed, install nozzle pulley, pulley bearings and
nozzle guides using Figures 9 and 12 as guides.
2. Place v--belt in nozzle pulley, route behind belt guard
(item 13) and install belt on motor pulley.
3. With a 3/8 in. drive torque wrench, pivot the motor
bracket from 200 to 230 in--lb (23 to 25 N--m) to set v--
belt tension (Fig. 10). Do not over tension belt. Hold
bracket with the torque wrench and tighten two (2)
flange head screws and flange nuts to secure belt ad-
justment and nozzle motor bracket.
4. Center belt guard around v--belt. Tighten cap screws
and flange nuts to secure belt guard to machine.
5. If bearing was removed from leaf spring (Fig. 11),
position bearing to leaf spring and secure with shoulder
bolt and lock nut.
NOTE: When installing the leaf spring assembly, the
leaf spring bearing mounting loops should be orientated
up.
6. Position leaf spring assembly and flat washers (item
5) to bracket. Make sure that five (5) washers are placed
between spring and bracket at each mounting hole. The
bearing on the leaf spring should be centered on the out-
side of the v--belt. Secure leaf spring to motor bracket
with two (2) cap screws (item 21) and flange nuts (item
22).
7. Fit nozzle and nozzle clamp to pulley. Tighten socket
head screw and lock nut to secure nozzle to pulley.
Torque fasteners from 45 to 50 in--lb (5.1 to 5.6 N--m).
8. Connect negative battery cable to negative battery
terminal. Tighten nut that secures battery cable from 10
to 15 ft--lb (14 to 20 N--m). Make sure that battery cover
is secured.
