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 broom switch to the off position.
3. Open the left broom chamber door (the door
opposite the driver’s seat).
4. Remove the knob 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 counterclockwise 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 knob and tighten into position.
11. Perform a main broom adjustment test and adjust
as needed.
