Shortening a PTO Driveline
1. With the implement attached to the tractor's three point hitch, and the PTO driveline not installed, sepa-
rate the PTO driveline. Attach the implement end to the implement and the other end to the tractor PTO
input shaft.
2. Raise the implement by using the tractor's hydraulic 3-point hitch to it's maximum lift height.
3. Hold the half shafts next to each other and mark them so
each end is approximately ½" from hitting the end of the tele-
scopic profiles.
4.
Shorten the inner and out guard tubes equally.
5. Shorten the inner and outer profiles by the same length as the
guard tubes. Using a rat tail file, round off all sharp edges and
burrs. Grease the telescopic profile generously before reas-
sembling.
Do not shorten too much, the proper overlap is a minimum of 1/3 the length of each
Caution: Slip Clutches may become hot. Do Not Touch. Keep the slip clutch area clear of a material that
may catch fire. Slip clutches have adjustable torque settings. The torque setting varies with the different
compression of each spring. All the springs should have an equal amount of compression.
Important: Do not over-tighten the compression nuts as this may impair performance or cause prema-
ture wearing of the slip clutch.
Slip clutch adjustments
Slip clutch must be adjusted before first use or after a storage period.
1. Using a marker, scribe a line across the exposed edges of the clutch plate and friction discs.
2. Back off compression nuts to free friction discs by turning each nut exactly 2 revolutions.
3. Start the tractor and run the driveline at a low idle to slip the friction discs. This will remove the dirt, corro-
sion and surface floss from the clutch plate faces.
4. Disengage PTO, shut down tractor and wait for all components to come to a complete stop.
5. Inspect the clutch and ensure that the scribed markings on the disc and plates have changed position. If any
two marks are still aligned, this is an indication that these discs have not slipped. It may be necessary to
completely disassemble the clutch to free them up.
6. After ensuring all discs are free, tighten the compression nuts, uniformly, exactly 2 revolutions to reset the
clutch original pressure.
