Paddle
•
Accessing paddle – raise the
hopper and install safety locks on
both lift cylinders. Remove the front
two pins on the chute assembly and
release the two spring pins located on
the paddle shield. Then flip these two
components towards the rear to gain
access to the paddle rotor.
•
Inspecting paddle blades – inspect
all four paddle blades for significant
damage, such as being bent or
cracked. Check to make sure that the
paddles are not rubbing on the deck
housing by looking for excessive wear
on the deck housing. Replace paddles
as needed. The replacement paddle
part number is 317180. See the parts
manual for an exploded view.
•
Inspect paddle bearings – inspect the
paddle bearings, located on each end
of the paddle rotor, for damaged seals
or excessive movement of the shaft
contained by the bearing.
NOTE: The deck liner is easier to inspect
and replace with the paddle shield and
chute assembly folded backwards.
•
Re-install all shields and parts re
moved before operating machine.
Brush
•
The brush is approximately 12” in (30
cm) diameter when it is new. As it
wears, the overall diameter will be
reduced. Replace the brush when
the overall diameter is less than 10” or
the sweeping performance is reduced.
Replacing brush
•
Remove the shield located on the LH
side of the deck to access the chain
drive. Remove the rear two bolts and
loosen the front two bolts.
•
Loosen the chain by removing the two
nuts that secure the idler spring. Then
remove the chain from the sprockets.
•
Remove bolt that secures the brush
sprocket and then remove sprocket.
•
Remove side skirts and retainers on
