34 30' Draper Windrower Shredder OM
Preliminary Draft 08.05.13
Pulley Assembly
Clean shaft, bore of bushing, outside of bushing and hub
bore of all oil, paint and dirt. File away any burrs
Insert bushing in hub. Match the hole pattern, not
threaded holes (each complete hole will be threaded on
one side only).
Apply a thread-locking compound to setscrews and
thread into the two opposing holes.
Position assembly on shaft and alternately torque set
screws to 35 ft. lbs.
To increase gripping force, hammer face of bushing using
drift or sleeve.
IMPOrTANT: Never hit bushing directly with hammer.
Re-torque screws after hammering.
Recheck screw torque after initial run-in, and periodically
thereafter. If loose, hammer face of bushing and re-torque
screws again and recheck screw torque.
Check alignment of the pulleys. Repeat pulley removal
and assembly procedures if necessary.
Install belt. See “Belt Replacement” on page 33 for
reference.
rotor removal
This service section is written as if the draper windrower
is upside down. If procedure is done with machine in
operating position, movable jacks will be needed to
support and move the rotors. The first rotor removed must
be the last rotor installed. The center bearing with the
bolts started through it, must be on the last rotor removed
(first rotor installed).
NOTE: Refer to “Rotors” on page 48 for parts breakdown
and assembly of rotor components.
Turn off all power to the draper windrower.
DANGEr: Failure to turn off power to the
draper windrower before removing the rotors
could result in serious injury or death.
1. Apply an appropriate supporting mechanism to both
rotors. (Chains and hoist)
2. Loosen the set screws on bearing lock collars.
3. Loosen and remove the outer bearing from the shaft
of the first rotor to be removed.
4. Remove the four nuts from the bolts holding the two
center bearings to the center plate. (The rotor on the
side of the removed nuts is the first to be removed
from the machine).
5. Slide the rotor outward away from center plate. (This
step might require the removal of the stripper bolts
located on the outside balancing ring. Make note of
which hole the stripper bolts are removed from and
replace in the same holes to insure proper balance.
6. Slide the four inner bearing bolts outward until the
center bearing on the first rotor is free. Be careful not
to slide them too far out or the second rotor might fall
free prematurely.
7. Remove rotor from the machine by lifting inner end of
rotor first to clear center plate and then sliding outer
shaft in through end plate.
8. To remove inner rotor bearing, loosen and remove flat
head cap screw, star washer and retaining washer.
Slide bearing off shaft. Remove collar.
Repeat steps 3 through 8 for the opposite rotor.
rotor Assembly
1. Slide bearing spacer on shorter shaft of the rotor.
(Shaft with 1/2 in. [1.27 cm] tapped hole in center).
2. Install roll pin into end of shaft.
3. Insert the four bolts through the bearing housing and
then slide it completely on the shaft.
4. Apply thread-locking compound to flat head screw.
Slide through washers and install into threaded hole
in shaft. Torque to 75 ft lbs.
NOTE: To determine left and right rotor, install so that
the bolt head on the knife U-clamp faces the
front of the machine.
5. Insert four outer bearing bolts into end plate with the
heads of the bolts inside the rotor cavity (nuts will be
inside belt housing).
6. Install rotor by inserting the outer end (long shaft) into
the bearing hole of the end plate.
