Adjusting the PTO shaft to the correct length
IMPORTANT:
When checking driveline PTO shaft minimum length, it is necessary to
align and level the tractor‟s PTO shaft with the gearbox shaft of the mower.
1.
Measure the shortest distance possible between the tractor PTO shaft and the gearbox
shaft of the mower. The lower links on the 3 point hitch must be hanging downward to
obtain the shortest length (see diagram 1).
2.
Shorten the driveline PTO shaft as follows:
a.
Make sure the tractor PTO shaft and the mower PTO shaft are level with each
other.
b.
Separate the two driveline shaft halves and connect one half to the tractor PTO
shaft and the other half to the mower gearbox shaft.
c.
Hold driveline shaft halves side by side to determine if they are too long. The
shields on each half should end approximately 3” from the universal joint shield.
Measure 3” back from the universal joint shield (dimension X on Diagram 2) and
mark that location on the inner and outer shields.
d.
Cut off the outer shield at dimension „A‟. Measure dimension „A‟ from the end of
the outer shaft and cut the same amount off of the outer shaft. Cut off the inner
shield at dimension „B‟. Measure dimension „B‟ from the end of the inner shaft
and cut the same amount off of the inner shaft.
e.
Remove all burrs from shafts. Keep shaft ends square not rounded off. Clean all
filings from drive shield tubes.
f.
Once driveline has been reassembled, check to make sure the driveline does
not
bottom out in the shortest position
