Main Broom Taper Adjustment
NOTE: It is not usually necessary to perform this
adjustment. However, if the
main
broom adjustment test shows a pattern
that is tapered in length (one end is wider
than the other), perform the procedures
which follow.
1. Locate the adjusting screws directly beneath
the hydraulic pump.
2. Loosen the jam juts on the adjusting screws,
and loosen the retaining bolt on the inside of
the mounting bracket.
3. Use the adjusting screws to raise or lower
the left end of the main broom. (The right end
of the broom remains fixed. All adjustments
affect the left end of the broom.)
4. After adjustment, tighten the retainer bolt and
adjusting screws.
5. Repeat the main broom adjustment test to see
that the broom is properly adjusted.
Main Broom Replacement
NOTE: Broom should be replaced if bristles
worn to a length of 1 inch; 2.54 cm or
less.
1. Turn the engine off and lock the parking
brake.
2. Push the main broom control lever to the
LOWER position
3. Open the left broom chamber door (the door
opposite the driver’s seat).
4. Using a ¾” wrench, remove the hex bolt on
the main broom idler mount.
5. Pull the main broom idler mount straight out
to remove.
6. Grasp the main broom by the plastic drive
hub, pull the main broom straight out and
clear of the broom chamber.
7. Depending on broom condition, you can
either rotate the old broom end-to-end and
re-install it or you can install a new broom.
Slide the main broom into the broom chamber
and align the broom with the metal drive hub
located at the far side of the broom chamber.
If a worn broom is being replaced, install the
new broom by first adjusting the broom arms
up, to better match the position of the drive
hub with the hub on the new broom.
8. Once the broom is started onto the drive
hubs, rotate the broom counter-clockwise
while pushing lightly against the broom.
9. Once the broom is fully engaged, replace the
idler hub while aligning the seats in the idler
hub with the broom’s drive hub ears.
10. Install the retaining bolt into position and
tighten with the wrench.
11. Close and latch the left broom door.
12. Perform a main broom adjustment test and
adjust as needed.
