Clutch/pressure plate removal

Morris Krodle · Jun 10, 2012

Anyone have any words of wisdom on how to separate the pressure plate from the flywheel on a B Farmall. I moved the three bolts in and followed directons from the book. BUT, it doesn"t buldge any. The other three bolts are removed. I"ve tapped it, used penetrating oil, and anything else I can thnk of. HELP!! Oh! I haven"t used the cutting torch yet, the last alternative.

An M/H clutch has 6 bolts that you have to take out to remove the pressure plate. The three bolts that you put in take up the pressure from the pressure plate so it is easier to reinstall and put the tractor back together.

Sorry no B specific advice, but hopefully you can use some of the info.

Edit - Yeah, there are 6 bolts to take out to take the pressure plate off a B. Everything looks pretty similar to the big tractors. You have to take these out. Look at the parts diagram and you can see what is going on pretty well.

Mine seems to be stuck all the way around the fly wheel, I've pried from behind the clutch thru the three holes on the outside of the fly wheel and also thru the two holes on the back side of the fly wheel. The new pressure plates don't fit all the way around like this one does. Will heat around the flywheel/starter ring help or is that a bad idea?

Are you sure the pressure plate isn't stuck to the clutch disc and the disc to the flywheel? Tap it with a big hammer. Post a picture of that clutch setup. Hal

I"ll try to upload a couple of pictures.

tapping solidly on the area around the holes with a ball Peen hammer (ball end) will distort the metal well enough to get it loose. Using heat in moderation will also work. I would go with the hammer first. It is toast anyway, so distorting it will not hurt it. Jim

Some times hitting the arm that the throw out bearing run on will flex the pressure plate enough to free them up.

Heat won't wreck a core but a hammer will if you bend it up.

How about removing those cap screws at one, four,eight and 10 o'clock? Three are on the fingers. That whole pressure plate assembly should come off with the 6 springs. Hal

If you've got a decent size slide hammer, flatten a piece of round stock, then bend the last 1/2 inch 90 degrees, insert in through the clutch center and bang in a few times. The disk is stuck to the flywheel, and the pressure plate is stuck to it.

The few that I've done came out easily. The one that didn't I used the bigger hammer theory. Between that and using a pry bar I got it out with no damage.

Two hammers, one on the pressure plate and used the other to hit the first hammer, loosened the pressure plate. And no the clutch was not stuck, I drove the tractor into the shop Friday for the overhaul. Was lucky, there is no damage to the pressure plate but will replace it and the clutgch since it"s apart. Thanks to everyone for the help.

You need to remove 6 bolts then it will come rite off. They are three "ears" with two bolts each. I dont see where you get the three you say you removed and it wont come off the flywheel.

mkirsch · Jun 14, 2012

gene, look at the picture.

It's an older style pressure plate which is clearly a full disk with 6 bolts evenly spaced around the outside.

Clearly all 6 bolts have been removed.

NEW pressure plates are the "3-ear" style.

Since you are sure the lining isn't stuck (as clutch functioned coming into the shop), the pressure plate must be stuck at the edge. I think the very edge is the only hard contact between the pressure plate and flywheel (may be remembering that wrong).

Loosen the 3 bolts you moved in to the inner holes. Leave them with a couple turns worth of slack between the heads and the face of the pressure plate. this will leave the pressure plate springs all pushing out on the pressure plate but keep things under control when it breaks loose. Then rap the edge of the pressure plate with a hammer. Don't go crazy with the hammer. If that doesn't free it, apply some heat along the edge of the plate and let it cool. try the hammer again. Prying on it while hammering can't hurt anything either.
