Has anyone ever upgraded a red belly 7000 to hyd clutch like the black belly 7000?

No, the dry one works just fine. Ask someone who has both versions which they prefer.

Running a round hay baler puts a lot of use on the throwout brg when you stop every minute or 2 and hold the clutch in for 30 sec. while you net wrap and dump the bale. I have a clutch job to do now because throwout brg locked up and wore off ends of fingers.

I don't think it would be too difficult to drill/tap/grind a channel into the throwout brg sleeve to be able to pump a shot of grease in it once a year.

Sam, I am sorry I can't find the info , but the solution to this is a diaphram clutch and a combine flat flywheel . The diphram goes 'overcenter' and relieves the stress on the bearing. New clutch technology gives holding ability and lower spring pressures .

Someone has even posted this on some forum before with a pressure plate that uses the 6 bolts of the dampner - which may have been drilled and tapped to one size larger? Maybe a search would turn it up. As to change over, wouldn't tackle it unless had one junked to switch. Black belly's were notorius for hard shifting unless trans brake adjustment was right on - and that is after oil is hot.

One thing I should've thought of in my message to you Sam, the black belly 7000 has the thicker discs and separator plates in the 1st range that are of a different pattern (different "channels" in the wear discs). My 7000 had heat damage to these discs (warped front plate, discs, and separator plates in the first couple closest to the front), so heat dissipation may be a problem on the maroon belly with only 4 of the thinner plates. Just something I thought of. And, to top it all off, AGCO no longer makes the wear discs, just the separator plates.

I use mine for round baling too... maroon belly with dry clutch. I typically make 1000-1500 bales/year. If you watch your technique of how you operate the clutch, you can still get 2500 (or more) hours on a clutch before rebuild. For the cost of the tractor and its age, that's pretty good to me. The techniques are: start out with low RPM's, never ride the clutch, never hold the clutch down while the twine is wrapping, let it out quickly and smoothly as possible in low range on the powershift, and when the clutch is out then bring it up to speed. You may find though, that the clutch fork could be due for a rebuild due to all that usage. And check to see if the fork shaft is straight - they sometimes can be bent. Clean and re-grease the bushings and it will feel like new. These are as easy of a tractor to due a clutch as any. My only concern with mine is the hydraulic valve stack, powershift, and line leaks. I've got multiple spots on the ground where it drips... how is yours for leaks?

The reason the valve stack leaks on a 7000 is the dumb engineer put the valve stack on with plungers up where dirt collects around them causing them to wear out

and pit. MACK
