General Service Continued
Pulley Removal Continued:
6)
Insert bushing into hub. Match the hole pattern,
not threaded holes (each complete hole will be
threaded on one side only).
7)
Apply a thread-locking compound to set screws
and thread into the two opposing holes.
8)
Position assembly on shaft and alternately
torque set screws to 35 ft. lbs.
9)
To increase gripping force, hammer face of
bushing using drift or sleeve. (Do not hit
bushing directly with hammer).
10) Re-torque screws after hammering.
11)
Recheck screw torque after initial run-in, and
periodically thereafter, repeat steps 4, 5 & 6 if
loose.
12) Check alignment of the pulleys. Repeat pulley
removal and assembly procedures if necessary.
CAUTION: Excessive screw torque may
cause damage to the bushing or sheave.
Rotor Removal
(Mower in Operating Position):
The belt and pulley should be removed with the
mower in operating position, but the procedures
for rotor removal and installation are greatly
simplified if the machine is turned upside down.
CAUTION:
If procedure is initiated with mower in
operating position, proper lifting devices
must be used to lift and move rotor.
A mower rotor weighs approximately 100
lbs./ft - i.e., a 73 inch mower rotor weighs
approximately 608 lbs.
Rotor Removal (Mower in Upside Down
Position):
This service section is written as if the mower is
upside down. If procedure is done with machine in
operating position, movable jacks will be needed to
support and move the rotor.
1) Refer to page 4-8 in Section 4 for an
illustrated parts listing.
2)
Attach a lifting device to both ends of
rotor, and apply a light tension.
3)
Remove the bearing guard by removing
the (2) 5/8” bolts and lock washers on
the right side of the shredder.
4)
Loosen the set screws on the bearings.
5) Remove the (4) 1/2” bolts and lock
washers holding the bearing to the side
plate and anti-wrap plate (located on the
inside of the side plate) on the left hand
side of the mower. Remove the bearing.
