ADJUST DRIVELINE LENGTH
Check Driveline Movement
1.
Remove auger from gearbox.
2.
Attach driveline to the tractor PTO shaft.
3.
Remove or place tractor drawbar in storage
position.
4.
Slowly raise and lower boom with the tractor
3-point arms. Check the driveline to see if it
separates, binds, or bottoms out.
NOTE:
Gearbox should lower to the ground. If not,
change hole location between A-frame and boom
or see if driveline is bottoming out. If driveline is
bottoming out it will need to be shortened.
Shorten Driveline (If Required)
1.
Remove driveline from gearbox shaft and tractor
PTO.
2.
Lower digger (with auger removed) until the input
shaft of gearbox is in line with the PTO shaft of the
tractor. This is the shortest distance required for
the driveline.
3.
Pull driveline apart. Connect driveline halves back
to the gearbox and tractor PTO shaft.
4.
Hold the two halves parallel to one another to
determine how much the driveline must be
shortened. Mark each end.
Figure 5
. Example of Overlap
5.
Raise the digger to the transport position using the
tractor 3-point arms.
6.
Hold the two halves parallel to one another and
check for a minimum of 6-inch (15 cm) overlap.
NOTE:
If driveline has less than 6 inches of over
-
lap, do not use this driveline. Contact your place of
purchase for a longer driveline.
NOTE:
If driveline has more than 6 inches of over
lap, the driveline will need to be shortened.
Cut Driveline
1.
Place driveline half in a padded vise and cut shield
off at the determined length.
Figure 6
. Cut Shield (Example)
2.
Place the cutoff portion of the shield against the
end of the shaft and use it as a guide. Mark and cut
the shaft.
Figure 7
. Cut Shaft to Length
3.
Repeat steps for other drive half.
4.
File and clean cut ends of the both drive halves.
5.
Apply a multi-purpose grease to the outside of the
male drive half. Slide the two drive halves together.
6.
Connect driveline to gearbox and tractor PTO.
Make sure spring-activated locking pin or collar
slides freely and is seated firmly in tractor PTO
spline groove.
7.
Make sure roll pin is installed in driveline yoke to
secure driveline to gearbox input shaft.
8.
Carefully raise and lower the digger to check that
the driveline does not pull apart or bind through its
range of motion.
9.
Use stabilizer bars, adjustable sway chains, or
sway blocks on your tractor lift arms to keep the
post hole digger from swaying side to side. Adjust
as tightly as practical for best performance.
