Driveline Shortening
Figure 1-11
7. If dimension “A” is less than 1", shorten driveline as
follows:
Refer to Figure 1-11:
a. Measure 1" (
“B1”
dimension) back from outer
driveline shield and make a mark at this location
on the inner driveline shield.
b. Measure 1" (
“B2”
dimension) back from the inner
driveline shield and make a mark at this location
on the outer driveline shield.
8. Remove outer driveline from the tractor power take-
off shaft and inner driveline from the tiller gearbox
shaft.
9. Cut off non-yoke end of inner driveline as follows:
a. Measure from end of inner shield to scribed mark
(
“X”
dimension) and record.
b. Cut off inner shield at the mark. Cut same amount
off the inner shaft (
“X1”
dimension).
10. Cut off non-yoke end of outer driveline as follows:
a. Measure from end of outer shield to scribed mark
(
“Y”
dimension) and record.
b. Cut off outer shield at the mark. Cut same amount
off the outer shaft (
“Y1”
dimension).
11. Remove all burrs and cuttings.
12. Continue with

Driveline Maximum Length
Figure 1-12
Check Driveline Maximum Length
Refer to Figure 1-12:
Driveline maximum length must, when fully extended,
have 1/3 overlap of the profile tubes with both inner and
outer profile tubes being of equal length as shown in
Figure 1-12. Check driveline maximum allowable length
as follows:
1. Make sure
“Check Driveline Collapsible Length”
on page 16 has been completed before continuing
with instructions below.
2. Unhook driveline profiles from the tractor and
implement.
3. If profiles are assembled together, pull outer and
inner drivelines profiles apart.
4. Measure and record “Free Length” of inner and outer
profiles as shown in Figure 1-12.
5. Lubricate driveline u-joints, bearings, and profiles.
6. Assemble driveline halves together until profile tubes
have exactly 1/3 profile overlap as shown.
7. Measure driveline “Maximum Allowable Length” and
record that length here ______.
8. Start tractor, raise implement slightly, and drive
forward enough to clear support blocks.
9. Lower implement to ground and shut tractor down
before dismounting. Refer to
24513
Outer Shielding has been removed for clarity.
IMPORTANT:
The driveline must be lubricated
before putting it into service.
