Split yet again!

My Massey-Ferguson Super 90 is in two halves again. Last week, I reported how the clutch was locked up. Today at 5 AM, I pulled it into the garage and went to work.

This time, I took pictures:

Left side. Just pulled in.Left the front loader outside.

Right front. Small drip under the middle - motor oil? I did put a new rear main seal in.

Right side.

Concrete blocks, plywood, and a 1/8" steel sheet for the floor jack to roll on. 6 AM.

Bottle jack on blocks under the transmission.

Batteries. Heavy!

Front loader braces and supports undone. Hood and fenders off. Wiring and piping disconnected

Instrument panel opened, to get to the roll pin in the steering shaft.

Draining the coolant. If you don't, when you take the temperature sender out of the head, it leaks.
2 x 4 blocks between the axle and front casting to keep the engine from pivoting on the axle

There's another 2 x 4 between the gas tank and the valve cover, to support the tank, which normally rests on top of the battery box.

Split. 6:40 AM.Notice the two fuel lines that need to be disconnected so the power steering pipes can stay with the back of the tractor.

You can see the throttle and fuel shutoff linkages above the starter. Small pipe drains oil from the power steering unit back to the transmission.

 Ready to pull the clutch. I can see the problem - one of the fingers on the pressure plate is stuck depressed.

Blurry close-up of the pressure plate - the finger on the right is stuck depressed. Smells like hot clutch.

My original thought was that one of the flywheel bolts came loose and jammed the clutch. Happened to me on a '66 Chevy C30 panel truck a long time ago. Not this time - all looks good here.

Clutch disk. No problems here.

Pressure plate LOOKS OK, but getting stuck like that indicates internal wear -so I ordered a new one. AGCO no longer stocks these - ordered from Tractor Joe's in St. Louis. Should ship next Tuesday.

So, the garage is occupied at least until next weekend.
