CLUTCH

As a tractor clutch is used, wear takes place naturally on the friction surfaces. This will affect the setting of the clutch pedal free-play which must periodically be corrected.

The clutch pedal on a Massey Ferguson 35 is adjusted correctly when there is 3/8 inch (double clutch) soft movement between the clutch pedal in rest position (up) and when the pedal begins to feel firmer when pressed. [3/4 inch for single clutch models]

Clutch Adjustment MF 35

Adjustment is accomplished by slackening the clutch pedal clamp bolt and turning the clutch release shaft in relation to the pedal. Re-tighten the bolt and then check the soft free-play. Re-adjust if necessary.

PTO CLUTCH

Once the clutch has been adjusted then the PTO clutch release studs can be checked/reset. Remove the access panel on the underside of the tractor clutch housing. Using feeler guages measure the gap between the adjusting stud head and the PTO clutch release mechanism. This measurement should be between 0.089 - 0.091 inches. To adjust the setting, slacken the lock nut, move adjusting stud, re-tighten lock nut and re-measure the gap. The photograph below clearly shows this - this tractor has been split.

Adjusting MF35 PTO Clutch

There are three adjusting bolts spaced equally around the clutch to measure and adjust. The clutch can be turned using a lever through the access panel. Applying a dab of paint to each stud after adjustment is a good way to be sure that you have done each one.
