tighten at this time.
Slide the gearbox shaft through the gearbox from
the left side. Insert the 5/16” x 1-1/2” keys into the
keyways of the round shaft and position the RH end
of the gearbox drive shaft within 1-1/2” of the LH end
of the clutch shaft.
Tighten the three bolts on the bushings on each side of
the gearbox to 15 Ft-lbs. or 180 In-lbs.
Tighten the set
screws on the bushings on each side of the gearbox
to secure the 5/16” x 1-1/2” keys into the keyways of

Reinstall RH header shield and secure with lynch pins
or quick lock pins.
Slide the bushing shield weldment over the gearbox
drive shaft and secure to LH side of gearbox using two
1/2” bolts and 1/2” washers.
Install bearings and flangettes to bearing mount plate,
slide onto LH end of gearbox drive shaft and secure
temporarily to vertical upright on back of header.
Measure between bearing and gearbox bushing for
correct length, and cut drive shaft shield to measured
dimension.
Remove bearing mount plate, slide drive shaft shield
onto gearbox drive shaft and reinstall bearing and
mount plate.
Check for shaft alignment up & down and front & back.
Tighten the bolts securing the gearbox mounting plate
to the gearbox and the bolts securing the gearbox
mounting plate to the mount plate support.
Tighten the lock collar on the bearing. Insert a punch
in the collar dimple. Tap the collar in the direction of
shaft rotation to lock. Then, tighten the lock collar set
screw.
For 25’ and 30’ headers, bolt shield mount plate to
bearing mount plate. For all other header sizes bolt
shield mount plate directly to LH side of gearbox.
Insert a 5/16” x 1-1/2” key into keyway at the left end of
gearbox shaft. Slide the clutch end of the PTO driveline
onto the gearbox shaft and tighten set screws.
Slide the slip clutch shield over the PTO driveline and
fasten to the shield mount plate using the 5/16” x 3/4”
bolts.
Install the driveline bracket support to vertical upright
closest to feeder house using 3/8” x 3/4” carriage bolts.
Combine end of driveline will cradle in this bracket.
Depending upon the combine model it may be neces-
sary to grind a notch or groove in the feederhouse
shaft to accommodate the quick connect button of the
PTO driveline. If a notch is necessary grind the notch
1-3/4” from the end of the shaft, 7/16” wide, and 1/8”
deep. This modification is typically needed on JD Ten
Series and prior combines.
