Driveline Adjustments - Priefert FMX Operator's Manual

Section 1: Set-Up Requirements
IMPORTANT: Never operate equipment with driveline extended
beyond measurement C. Never operate equipment with driveline
collapsed to less than measurement D. Before you begin the
driveline adjustments; Priefert strongly recommends that you
request your dealer to fit your driveline to your equipment.
Driveline Adjustment
Refer to Figures 1-2 for Minimum and Maximum Lengths.
IMPORTANT: Adjusting the PTO Driveline requires that all cuts be
made equally to the inner/outer guards and the inner/outer shafts.
1. Remove the PTO driveline from the tractor's splined output shaft
and the implement's splined gearbox.
2. Pull the inner and outer shafts apart.
3. Remove the PTO shields (guarding).
4. Attach the implement's inner cylinder to the implement's
gearbox shaft.
5. Pull on the implement's PTO driveline to ensure that it is
securely attached.
6. Attach the tractor's output shaft to the tractor's PTO gearbox
shaft.
7. Pull on the tractor's PTO driveline to ensure that it is securely
attached.
8. Raise and lower implement to find the shortest operating
distance between the gearbox input shaft and tractor's output
shaft.
9. Hold both halves parallel to each other in the shortest operating
distance and mark them.
10. Measure the marks made in Step 9 and record them to shorten
the outer and inner guards equally.
11. Raise and lower implement to find the maximum operating
distance between the gearbox input shaft and tractor's
output shaft.
12. Hold both halves parallel to each other in the maximum
operating distance and mark them.
13. Check that the driveline has a minimum of 6" (152.4mm) overlap
or 1/3 the total length of the driveline.
14. Measure the marks made in Step 13 and record them.
12
15. Disconnect the implement inner cylinder from the implement's
gearbox shaft.
16. Disconnect the tractor's output shaft from the tractor's PTO
gearbox shaft.
17. Securely clamp the implement driveline guard shield section in a
bench vise and cut off the guard at mark. File off any burrs. Repeat
this step for the tractor driveline guard shield. Use one of these
sections to create a cutting guide for the shaft and cylinder.
18. Use a padded bench vise to securely clamp the implement
cylinder before cutting. Do not over tighten as this may damage
the cylinders.
19. Using the guard as a guide, mark the cylinder and cut. File any
burrs and clean off filings. Do not round the ends of the cylinder
when filing.
20. Repeat steps 12 and 13 to shorten the tractor driveline shaft.
21. Apply grease to the inner shaft.
22. Reassemble the driveshaft, and securely attach the driveline
guard.
23. Reattach the PTO driveline to the tractor and implement. Make
sure that these are securely attached before attempting to
engage the PTO driveline.
24. The driveline should now be moved back and forth to insure that
both ends are secured to the tractor and implement. Reattach
any end that is loose.
25. Hook driveline safety chain in the hole in the inner driveline
guard. Attach the other end to the implement's main frame.
26. Hook driveline safety chain in the hole in the outer driveline
guard and attach the other end to the tractor main frame.
27. Start tractor and raise implement just enough to remove blocks
used to support the implement frame.
28. Slowly engage tractor's hydraulic 3-point to lower the
implement. Check for sufficient drawbar clearance.
drawbar ahead, aside or remove if required to eliminate binding.
29. Check to make certain that the driveline overall length does not
extend beyond the maximum recorded length as in Step 14.
