Driveline Shortening
Figure 1-15
Shorten Driveline
Be sure to check driveline collapsed length first.
1.
Unhook driveline from tractor power take-off shaft.
Pull outer and inner drivelines apart.
2. Reattach outer driveline to tractor power take-off
shaft. Pull on inner and outer driveline yokes to be
sure universal joints are properly secured.
3. Hold inner and outer drivelines parallel to each other:
a. Measure 1" (
“B”
dimension) back from outer
driveline universal joint shield and make a mark at
this location on the inner driveline shield.
b. Measure 1" (
“B”
dimension) back from the inner
driveline universal joint shield and make a mark at
this location on the outer driveline shield.
4. Remove driveline from tractor power take-off shaft
and gearbox shaft.
5. Measure from end of inner shield to scribed mark
(
“X”
dimension). Cut off inner shield at the mark. Cut
same amount off the inner shaft (
“X1”
dimension).
6. Measure from end of outer shield to scribed mark
(
“Y”
dimension). Cut off outer shield at the mark. Cut
same amount off the outer shaft (
“Y1”
dimension).
7.
Remove all burrs and cuttings.
8. Continue with
“Check Driveline Maximum Length”
Check Driveline Maximum Length
The driveline maximum allowable length must, when fully
extended, have a minimum overlap of profile tubes by not
less than 1/2 the free length with both inner and outer
profile tubes being of equal length.
1.
Apply multi-purpose grease to the inside of the outer
shaft and reassemble the driveline.
2. Assemble the two driveline profiles together with just
1/2 overlapping of the profile tubes as shown. Once
assembled, measure and record maximum allowable
length here. ________
3. Continue with
“Check Driveline Interference”

WARNING
To avoid serious injury or death:
A rotating driveline must not exceed an angle of 25 degrees up
or down, and never engage a driveline while at an angle
exceeding 25 degrees up or down. The driveline can break and
1.
Make certain driveline yokes are properly attached.
2. Start tractor and raise Rotary Cutter just enough to
remove support blocks from under the cutter.
3. Slowly engage tractor hydraulic 3-point control lever
to lower cutter while checking for sufficient drawbar
clearance. Move drawbar ahead, aside, or remove if
required.
4. With power take-off removed, raise implement fully
up to make the following checks below. If driveline
exceeds any of the limits listed, set tractor 3-point lift
limiter at a height that will keep the driveline within its
lift limits and to avoid premature driveline breakdown.
•
Driveline does not exceed 25
o
up.
•
Driveline does not exceed maximum allowable
length recorded in step 2 under
