Setting the safety clutch
There is a safety clutch on the machine side of the coupling shaft. This
safety clutch protects the machine against overloading.
First check the setting of the pressure springs in the safety clutch.
The spring length must be 1 1/16”.
A static calibration test can be performed with a torque wrench.
Set the torque wrench to 220 ft.lbs.
Friction should occur as soon as it is turned.

It is possible that the coupling should be “broken out” at a higher
torque for the first time.
Attach the loose machine component of the coupling shaft to the
drive axle.
At the side of the machine the coupling shaft is secured with a
bolt.
Shift the coupling shaft onto the drive axle of the machine.
Take care that the large hole in the coupling shaft hub is above the
chamber in the hole of the drive axle.
Push the bolt through the coupling shaft and drive axle.
Don’t tighten the nut yet, you still have to adjust the length of the
coupling shaft and put back the protection sleeves.
See paragraph »Checking the coupling shaft length« on page 64.
Manually align the two coupling shaft halves.
Check the length and set it as described in paragraph »Shortening
the coupling shaft« on page 65.
After shortening and assembling the coupling shaft, tighten the nut
at 52 ft.lbs.
Shortening the coupling
shaft
The profiled tubes must overlap as far as possible, with a 6” minimum.
At the outer edges, the profiled tubes must have at least 1” free
clearance, when the tractor PTO shaft and the machine drive axle are
level.
Cut off the two profiled tubes to achieve the 1” clearance.
Deburr both ends.
Clean the coupling shaft.
Shorten the protection sleeves by the same length.
Slide the coupling shaft halves into each other.
Connect the coupling shaft of the machine and the tractor.
Lift the machine with the power lift in the highest operating position.
