1600 PTO Clutch update and additional questions

Got the parts from AGCO, ordered the two disc and new throw out bearing. and was able to get the three little springs. I ordered the aftermarket disc. took apart the clutch, no real problems there. I don't believe it has ever been apart before and is the original clutch. Got it apart and the splines on my shaft looked pretty good, the old disc were pretty worn, one disc seemed to have more wear as it had a small part of the disc gone. Seems to me the snout were the throw out bearing moves has a lot of wear as you can see where the bearing rides. I took some emory cloth/sand paper and cleaned the metal disc off. There also seems to be a wear on the front cover where the levers on the pressure plate have grooved the inside of the front cover, is this normal? I decided I would put it back together. put all the shims back as when it came apart but now the clutch is two tight when you snug the front cover down, there doesn't seem to be any room for the throw out bearing to travel to engage the clutch. when I back the bolts off the front cover I can then get the bearing to move and to engage but it would seem that I would almost need double or triple amount of shims and longer bolts to get this to work is this normal? There are about 20 shims to each side of the plate. I believe I would need add about 60 shims to each side to get it to work right. I tried to mark everything to make sure it went back together the way it came apart. I believe I have everything in the correct order, I really believe I need to go back and order a new pressure plate because of the wear on the snout where the throw out bearing rides and wear on the levers on the inside cover. I think I will also the new plates for the front cover because of the way they are grooved from the levers riding against it. Also order or make some more shims. Has anyone else come up with these same problems? or is there something I am doing wrong or missing here?

I guess I should ask this question first, Are you sure that the 2 clutch disks are in the right way? Bandit

I have to admit that was my first thought too.
But I have them put together as in the pictures from the first post. In fact I don't see how there is only one way for them to go because if you have the disc turned around there is no way they can make contact with the metal center plate. The nose on the hub of the disc will not allow them to make contact.

It took several times reading this but I think I got the answer. If you are trying to engage the clutch with the throw out bearing by hand and not the lever (on the cover) you will never get it to engage this way. I would put it back together with the new disks in it and the shims you had in it, Tighten it up with the throw out bearing fully released and bolt the cover back on and hook the lever back up and try it and see how hard it takes for it to brake over center (about 40 lbs of pull). If its too hard you need to add shims till you get that nice snap in the brake over. It is all trial and error. The can be a pain in the butt taking it on and off to get them right but its the only way to do it. Bandit

That's probably true we did bolt the cover on and try to engage the lever and it seemed like it was to tight and then I did loosen it up and engage it by hand with the cover off, So I see what you mean. I believe it needs more shims to make up the difference for the new plates. I am going to order some more shims and replace those other plates. I was glad to see my hubs were not chewed up like the ones you had in your pictures and splines on my shaft were not as wore as yours.
Thanks for your help. Do you have yours repaired yet?

Got the parts to fix it but I haven't had time to get to it yet, For the last week it seams that all I have done is fix brake lines on our cars and trucks as well as mom and dads. One goes they all go, It never ends it seams. I will get to it sometime soon unless something else brakes down. Today I got to fix a 550 Oliver for dads next door neighbor because she left the key on. I never seam to run out of work to do. Bandit

Well hope things get better for you, I priced those other parts today, Ouch! AGCO wanted $300 some odd dollars for the pressure plate, I decided I would pass and use what I have. also the shim kit was $100, I think I have some shims left over from a New Holland haybine I had that I will try to trim up and use, If not I can go to Lowes and buy all the brass shim stock I would need for a few bucks. Never ceases to amaze me what these implement dealers want to charge for parts!

Check on Ebay for the shims, Seams like I saw a set of shims for $50 new I think. Its worth a look to see and save some money. Bandit
