Massey 3095 clutch

[Chaffe.2008]

Hi, I have a Massey 3095 with a slipping clutch. I sent it away for repair and it has had a new clutch fitted and the flywheel skimmed. It has been returned but the clutch appears to be slipping still. When it was dismantled the mechanic said either the clutch or the flywheel had washers behind them to push them out. So after great expense I still have the same issue. Please could someone advise

There shouldn't be any washers. Clutch should bolt directly to flywheel. Was the flywheel skimmed correctly? ie the same amount removed from the clutch mounting flange as from the working face.

I hane no idea. I was told that perhaps this could be the issue but I didn’t take apart. I was told a new flywheel would cost me £2k hence the skim

Skiming is fine as long as the measurements are kept correct and it hasn't been skimmed to many times

A new flywheel would be near 2k

You don’t know anywhere I might get one a little cheaper?!

Make sure that's your problem first. With a new clutch and plate and a correctly machined flywheel the fingers of the diaphragm should be straight or even dished in a bit, if they are close or toucing the cover then something is wrong. You can see this thro the bottom plate.

As long as every time it's skimmed both faces are done the same it shouldn't slip, your man now may have done it right this time but who knows what's been done in the past.
Then there are two types of clutch plate with different thicknesses. MF kept the old original plate available in case you only needed to change just the plate (like that was ever going to happen) the new type came in a kit of plate and pressure plate. The thinner plate required a different depth from the face to the pressure plate mounting face.
There is a minimum mesurment, 34mm rings a bell and I think it's from the face down to where the fixing bolts are.
More machining past the minimum means 1. The face material is softer and 2. The slave cylinder can't push the pressure plate fingers enough to fully disengage the clutch. It won't cause clutch slip.

Is the tractor speedshift or dynashift? And are you sure it's clutch slip and not those that are slipping.

Hi. The guy came to have a look. Removed bottom plate and told me it’s still slipping himself. It’s a dynashift. It’s a 1994 so I’m told it’s an older machine so I’m guessing a more expensive flywheel. So I’m guessing from the replies I’ve had that the best way forward is to split it again

Does it have speedshift?

 

[Chaffe.2008]

Yes I think so. A lever by the steering wheel that goes A - D?

It would be strange to replace the clutch and still have exactly the same symptoms. Was the old clutch actually worn? Is the mechanic sure it's actually the clutch slipping and not something else?

If it’s dynashift it wouldn’t slip in all four powershifts I wouldn’t think so. IIRC they revert to D if there’s electrical or hydraulic problems therefore I assume D pack is spring operated.
If it’s slipping now with new clutch it would be fairly obvious if you can see through the inspection hole. Pressure plate would be showing signs of blueness id it’s really been slipping. Even if you started it from stone cold, high gear with foot on brake and let clutch out most of way for 15-20 seconds of its slipping it would generate heat that you could obviously feel in the pressure plate when you get back underneath (with engine off and key in pocket obviously)

He’s an experienced mechanic on JD and says he’s not worked on one of these for years so I’m sure he knows what he’s doing. I hope so anyway

Clutch slave cylinder not releasing pressure fully??

Cluth plate wrong way round?? Possible on some MF tractors, not sure about 3095

This is worth a shot I think. The clutch biting point is quite low on the pedal so it could be that

The manual says if you resurface the flywheel,both the flywheel surface and the flange where the cover bolts needs to be ground down. If you don't do the flange the clutch will slip. Secondly you have to change the release bearing for the 45mm version so you can fully depress the clutch after grinding.

I suspect someone has ground the flywheel before and not replaced the bearing and used washers as an alternative rogue method

Make sure the hydraulic slave cylinder has been bled properly?
