HINGED TOP HOPPER SEAL
The hinged top hopper seal is located on the top of
the rear hopper opening. It keeps debris in the
hopper while the hopper is being raised to the
“dump” position before the hopper dump door is
opened. The seal should be inspected for wear or
damage after every 100 hours of operation.
TO REPLACE AND ADJUST HINGED TOP HOPPER
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 stationary hinge bracket bolts to
remove the hinged top seal assembly.
