The original subject was "Re: TO35 Dual Stage Clutch Adjustment".
I
have a similar problem with my 1959 Fergy 35, dual clutch.
The gear change works acceptably. The PTO however, can only be engaged either with the engine off, or, by moving the PTO lever whilst the engine is stopping, teasing it in as the shaft rotation slows. Any attempt to engage the PTO with the engine running just results in a very noisy grinding of gears.
I have adjusted the pedal free travel as per the manual; 9.5mm. I have adjusted the 3 pressure plate adjusting screws so that the clearance between the screw heads and the rear pressure plate is around 2mm.
If I get my missus to press the clutch pedal down while I?m observing the clutch operation through the access door, I can see that the second phase of operation is not working as required; only one of the three adjusting screws can be seen pressing against the rear pressure plate, with the result that there is, at that point on the circumference of the driven plate, a visible gap. At the other two adjusting screws, the rear pressure plate does not seem to move, with the result that there is no visible separation between the rear pressure plate and the driven plate at those points
I conclude that, whoever fitted the clutch did not adjust the three fingers properly before joining the two parts of the tractor.
I further conclude that it is not possible to adjust three fingers once the tractor is joined once more.
