Have been looking for a PTO clutch assy. E0NNN751AB. This clutch calls for 7 discs per the New Holland parts site, fits 2810 thru 4610 and 335. When I google the part number there are a lot of listings for E0NNN751BA which is a 5 disc clutch for the 5000 and higher series tractors. Anybody know where I can look?

Pressure should be 220-230 so it's down a little, I'd try to get the pressure set before tearing it apart.

Could have a valve not sealing, line fitting leaking or clutch piston seal leaking.

The regulating valve controls the pressure coming from the pump, if you can't shim the valve to get the proper pressure ether the pto section of the hydraulic pump is bad or the line suppling oil from the pump to the regulating valve is leaking.

If you've slipped the clutches very much them may need replacing but make sure to have the correct pressure before using it again or you could burn up a new set of clutches.

So you've checked the regulating valve pressure and had the lift top off to check the control valve pressure.

The pto clutches can fail but it rarely happens on these tractors, more times it's low pressure that allows the clutches to slip.

Yes, had the lift cover off and on a couple times,and checked pressures at regulating valve and control valve. Don't have my notes in front of me but IIRC pressure at regulating valve was running around 160 PSI and about the same at the control valve.
I thought about adding a shim to the regulating valve to up the pressure to see if it helps. The manual states that if the PTO slips under load to overhaul the clutch assy. Mine slips to the point of not turning at all when bush hogging heavy fescue.
What do you think? Any chance shimming the regulating valve would help? May give it a shot, sure easier than splitting the tractor.

The assembly is no longer available new, salvage yard would be the best place to look..

Is there a reason you need the complete assembly?

I knew that CNH no longer had them but I figured there would be an aftermarket available. Oh well. I wanted to have a complete clutch assy. on hand when I tear it down to save time. Guess I'm going to have the opportunity to rebuild one if I can come up with all the parts. I have performed all the diagnostic steps for a slipping PTO in the IT manual and everything points to the clutch pack.

Today's Featured Article - It's Alright Where It Is! - by Anthony West. I have a tale of a different kind to tell. Whilst rooting in the hedge bottoms this week I had cause to visit Chapel lane Farm, the home of an eccentric gentleman by the name of Austin Kendall. I had heard rumours that an old Case Model C was languishing away in the back of one of the outbuildings there. So off I went in search of what would turn out to be a very rare and unusual tractor. Mr Kendall is an excitable chap to say the least. He is amongst the last of a dying breed of farmer who ... [Read Article]
