Massey Ferguson 65

From what I can see, understand, and remember, the first stage press the springs, and the second stage press the belleville spring.

This means if you have too many springs on your clutch you shall feel the first stage is getting harder, or easier to press if too few springs.

If I understand you correct it is the second stage you feel is very hard, and that leads me to think there is something binding / blocking somewhere.... like a transport lock or something.

Just a thought.

MY MF manual, 819 121 M1 says 12 springs on a MF 65 with the A4-192 diesel engine.
This may not be correct if you get a clutch from an after marked supplier.

But the number of springs have nothing to do with your problem, that is adjustment and wear.
The number of springs only makes the pedal harder or easier to press down. And, of course, too few springs may cause the clutch to slip during heavy loads.

Hm... I am still thinking. My cousins MF 165 is exptremely hard on the pedal, prolly too many springs there. But, everything still works normally.
Now I come to think that I have seen clutch assemblies come with some sort of transport locks. May this be the problem, that there is a transport lock in there you never saw or knew about that blocks the secondary stage ?

Just a thought...

The MF 65 has a 4 clyinder 50 HP gas engine and the clutch was new with a new clutch plate and release brg.

See other reply on locks.

this is on their Clutch page fo Massey.
quote from BARECO.com -- parts supplier they have nice pictures of all the parts , but no pricing. ray-s

this problem was addressed ayear or so ago. Go to search bar up top and type in "hard clutch" you should get to a list of threads. Go to #143 clutch problem with 135. about page 5 or6. There is talk there of too many springs and how to take some out. ray-s

Having to apply anything more than comfortable pressure is not acceptable. Observe the operation of the clutch from underneath with a torch while someone presses the pedal. Is there any sign of the spring coils touching? If so the main plate is probably being released but there is not enough travel left to accommodate the release of the PTO plate. How many coil springs are fitted.
They should be red and you should have a total of 9. If you have 12 you have a unit built for a larger tractor.
If the coils are binding you will either need to decrease the PTO plate clearance slightly or fit a set (or two) of shims between the clutch unit and flywheel. One set was fitted as standard to most 11" clutch units. We have had to fit additional set to obtain correct movement in the past. The last part number that I have is 828 039M1 Spacer (set of 3) You have not mentioned these spacers (shims) so were they fitted originally, have you left them out?
First of all observe the operation then please come back if I can help you any more.

I don't have the tractor where I can check things right now----but I believe the clutch has 12 springs. There were no shims just the air ring between the clutch and the flywheel. The clutch had been rebuilt before and the original casting was brassed in several places when it had broken so I got a complete unit.

Will get back on the Number of springs there is.
