On turning the control knob A onto 1, the air reaching the fitting I passes through the control valve B and from the fitting 2 supplies
the clutch of the power take-off C, thereby making it possible for the drive to pass from the gears of the timing system to the P.T.O.
The control knob A is in this phase locked on position 1.
When turning off the power take-off, turning in the opposite direction, the knob locks and automatically returns onto 0.
Disconnect the fitting (1) of the oil delivery pipe and the air
fitting (2) of the clutch engagement control.
Unscrew the eight fixing screws (3) and take off the power
take-off (4).
Refitting
Perform these steps in reverse order, tightening the
fixing screws to the required torque.

To refit the PTO, both when replacing it and when reusing
the previous one, it is necessary to replace the gasket.
Until the power take-offs are provided with plates stating the
necessary dimension to calculate the correct thickness of the
gasket, it is necessary to fit the gaskets of 1+0.5 mm provided
in kit form and overlap them.
This is to make the gears engage correctly.
In the future the power take-offs will have a plate stating a
dimension that, when added to the one punched on the
flywheel cover and using a specific table, will make it possible
to calculate the type of gasket to fit exactly.
