ASSEMBLY
4.5 RIGHT HAND DRIVE KIT (25-35 FT. HEADERS)
Place all controls in neutral or off, stop combine engine,
set parking brake, remove ignition key, wait for all mov-
ing parts to stop, then properly block machine before
servicing, adjusting, repairing, or unplugging.
WARNING
1. Install a bushing to each side of the gearbox (Figure 11).
Make sure the bolts are inserted in the non-threaded
bushing holes. The threaded set of holes is used to
remove the bushing. Do not tighten the bolts yet.
2. Slide the provided drive shaft through the gearbox bush-
ings. When doing so, install a 5/16” key in each bushing.
3. Adjust the drive shaft so that approximately 1-1/2” of
shaft extends past the right gearbox bushing. Then,
torque all gearbox bushing bolts to 17 ft-lbs. each.
4. Attach a shield weldment to the right hand side of the
gearbox with two 1/2” x 1” bolts and washers. Torque
to 75 ft-lbs.
5. Slide the drive shaft shield over the left end of the drive
shaft.
6. Attach the shield mount assembly, bearing and two
flangettes to the lipped side of the bearing mount plate.
Use three 3/8” x 1” hex bolts, washers and nuts. Torque
to 30 ft.-lbs.
7. With the flat side of the bearing mount plate facing the
gearbox, slide the bearing onto the left end of the drive
shaft. Slide the bearing over the shaft until the bearing
mount plate rests against the left side of the vertical
header angle. Cut the drive shaft shield as needed to
allow room for the bearing.
8. Install the bearing mount plate to the vertical header
angle. Feed two 3/8” x 1” carriage bolts through the
existing square holes in the angle and secure the bolts
with washers and serrated flange nuts.

9. Ensure the drive shaft is aligned properly from the
gearbox to the bearing. Adjust the gearbox position as
necessary for correct alignment. Then, torque all 1/2”
gearbox mounting bolts to 75 ft-lbs. Torque 3/8” bearing
mount plate hardware to 30 ft-lbs.
10. Tighten the lock collar on the bearing. To do so, insert
a punch in the lock collar dimple. Using a hammer, tap
the punch in the direction of normal shaft rotation until
the collar is tight. Then, tighten the lock collar set screw.
11. Using a 5/16” key, attach the slip clutch end of the pro-
vided driveline to the left end of the drive shaft.
12. Slide the slip clutch shield over the opposite end of
the driveline and attach the slip clutch shield to the
shield mount assembly. Use three 5/16” x 3/4” bolts
and washers.
13. Determine an appropriate location to mount the driveline
support bracket (see Figure 10 for reference). You may
mount the bracket to existing holes in the header if
available. Otherwise, mark and drill two 13/32” holes
through the header for the bracket. Install it with two
3/8” x 1” hex bolts, washers and serrated flange nuts.
