While we are having mild weather and no winter yet, I decided to pull the motor on my PK and check the clutch, throw out bearing etc. to see if I could remedy a gear grinding problem I have been living with because I thought that it was the nature of the beast. Much to my surprise I found one of the clutch throw out arms completely gone and the bracket bent. Everything else looks real good and I found a used pressure plate on Ebay. The clutch would never fully disengage when putting into gear from neutral. It would just push on one side and the other side would drag. I will clean and grease everything while in there and I'm in hopes I can get it to shift quietly like a few PK's we've seen here.:praying:

Hmmmm, wonder where it went? Could it have just fallen off in the field? I would hace expected it to be chewed up into tiny parts in there.

The clutch on this tractor never felt right to me and it always grinded gears. I believe at some time prior to my ownership the broken arm got removed and never replaced after it broke off. I don't think it could have fallen out as it is a closed space and no scratch marks anywheres.

So--in other words--somewhere down the line--someone pulled it apart--looked at it--BUT didn;t fix it--just stuck it back together?:banghead3:banghead3

Only explanation I can see..just plain foolish,,,

Unless it broke up in little pieces and fell in the field, that's all I can think of.

Some more food for thought. I Decided to check the pilot bushing and seal while waiting for a pressure plate and found another surprise. I was able to pull the flywheel and hogshead without much trouble. I pulled out the seal and bushing and snap ring. I found the seal was not seated properly against the bushing and it was crushed somewhat. This also created drag on the input shaft contributing to my gear grinding issues. I replaced the snap ring, bushing was fine, replaced the seal, cleaned and painted everything and I think it will run like new soon.

Hi,

Can I ask what seal you are talking about?
I don't think I've found anything in the pilot bushing area that I would consider a seal. But that doesn't mean there shouldn't be!

Also, I would think that if a pressure plate finger came off during operation that there is enough open area in the "hoghead" to allow its escape.

Good luck in putting it back together and enjoy its improved operation.

Yeah there is a seal (CR n1346) that goes in right after the bushing up against it. Snap ring/bushing/seal in that order. It seems those openings on the hogshead do not expose the clutch area. The throwout bearing and arms are not really exposed and I'm thinking it would have had to break up to fall through.:dunno: I can't wait to put it back together and try it.

Dave,

I can't wait either! LOL! You are going to like the way it glides instead of grinds.

Steve
Yeah, have you had grinding problems before too? Thanks for your instructions on the bushing and seal, it worked perfect.

When I got mine, the engine was off and in pieces so I just needed to know how to get it back together and there were no real manuals that told you how to do it. So, when I started to gather info from the guys here and on the yahoo PK group, I printed everything down and took pictures of the steps and put together that little quick reference guide so anyone could take it and use it. If you noticed that I missed anything, let me know and I can update it.

One of the trannys was ok except for the fluid and the other was stock in gear so I took it apart and got it unjammed and it has been fine since. It will grind a bit, every once in awhile but only because I'm rushing around and don't give it a chance to release.

Just got it all rebuilt and reassembled. I can't believe how well it shifts now and absolutely no more gear grinding. Thanks for all of everyones help and suggestions here on the forum. Hopefully this thread will help others with the same problem as I know alot of us had the same issues with these PK's. I always thought the grinding was normal for these.:thThumbsU

glad you got it worked out. since i read your post on the other thread about bad shifting i thought about how long i wait when i shift. i found out that at any rpm i can up shift by just pushing the clutch like i would in a standard vehicle, down shifting i have to wait to come to a stop then i can shift without grinding.

See your pic of the plow. I have one but haven't figured out how to install. Could you either let me know or send pics. Thanks
If your tractor is around a 73 or later I think it has the mounting blocks required already on the frame. If it's older than that like mine a 69, then you have to install the mounting blocks which are no longer available but they can be fabricated by a welding shop. Here are a few pics and let me know what detail you need to mount yours and I'll be glad to help.

My tractor is a '71. Attached are pictures of my plow. BMXKID313 said I am missing some parts. My grandfather had this plow attached at one time, but I never saw how it was done.
Thanks for your help.
I see, you have the older plow and BMX is right you have parts missing. Here is the diagram that shows what you need. It looks pretty easy to hook up to your tractor. I think you can make those missing brackets. Take a look at the diagram and the item labeled #41 are two little ears that hook up to those two hooks under your front axle. The two rear brackets simply bolt up to the original holes already in your frame.
