10. Open the right brush door.
11. Remove the main brush.
12. Looking through the right brush door opening,
check to make sure approximately
three---fourths of the top seal is making contact
with the machine frame. If three---fourths of the
seal is not making contact, raise the hopper,
engage the hopper support bar, loosen the
shell cam jam nut, and turn the adjustment bolt
counterclockwise to increase the amount of
contact or clockwise to decrease the amount of
contact.
NOTE: If too much of the top hopper seal contacts
the machine frame, the hopper may not be able to
seat in the “operating” position, causing poor debris
pickup.
Tighten the jam nut, raise the hopper, disengage the
hopper support bar, lower the hopper and recheck
the seal contact. Repeat the procedure as
necessary.
HOPPER DOOR HINGE SEAL
The hopper door hinge seal seals the area between
the hopper door and the hopper. Check the seal for
wear or damage after every 100 hours of operation.
TO REPLACE HOPPER DOOR HINGE SEAL
1. Empty the hopper.
2. Stop the machine on a level surface and
engage the parking brake.
3. Raise the hopper, engage the hopper support
bar, and lower the hopper onto the hopper
support bar.
WARNING: Always engage the hopper
support bar before working under a raised
hopper. Do not rely on the machine hydraulic
system to keep the hopper in the “raised”
position. The hydraulic system may leak
internally, allowing the hopper to lower, crushing
anything under it.
4. Stop the engine.
WARNING: Always stop the machine on a
level surface, stop the engine, and engage
the parking brake before working on the machine
to keep it from rolling.
5. Remove the two seal retainers and the old
hinge seal.
