The hydraulic reservoir rebuild kit arrived today and the xeroxed info sheet that came with it leaves a lot to be desired.

I need to ask these questions:

The head is off and the pistons are exposed. On the top of each piston, centered, there is a large nut. I need to know how the pistons come out and what has to be removed to get them out of the bores. There are more O rings in this kit than I imagined, so I assume there are lots of goodies inside that need to be yanked out. The info sheet said there are two versions..my tractor is a '53 model and I have no idea what version it is or how to differentiate betwen the two. Sure, the kit said one used 8 'O' rings and the other 10, but is there anything else that points to what version I have? I want this to be a happy and productive experience(!), so if there is anything I need to be aware of..spill your guts! Thanks.

The diagram in the parts manual is better. The pistons pull out, perhaps with some difficulty. What I think you are calling the "head" is actually the top cover, not all units have that, the one on my C that I have had apart doesn't. The head is actually the thick piece at the rear of the reservoir, that is the way the thing comes apart. You can tell which o-rings by comparing them with the existing ones. I have not seen the nuts on the pistons, but, again my unit does not have the top cover that exposes the pistons -- I may be misinterpreting your description though. I haven't had mine apart for 4 years.

Oh, it is amazing what you discover when you get brave enough! I am referring to the head...sure enough. This reservoir has a top and bottom cover...removed, neither expose the pistons, just the internals of the reservoir itself...not much to see.

Annnywayyy, I took the digital camera with me to the shop...for instant memory (he-he!). if anything in my 48+ years, I have learned..it's that I ain't getting any smarter as time goes by. That camera doesn't forget anything! I shoved the pistons out and the rest of the innards, cleaned everything up and started removing and replacing O rings. When a piece was finished, it went back in it's respective hole. The spool valves...taught me they also have a tiny piston inside that takes a matching tiny O ring. Then, the control valves.....the info sheet said if they only had one O ring, not to install the extras...eventhough they have obvious places for them. Mine only used one, so only one went back on. I also learned that these control valves will only go in their original hole/bore. I had to stop for the evening, but am on a roll now. My only question now is: why did the kit have two (2) head gaskets? One is thicker than the other...I used the thin one. I also have no idea what to torque the head bolts too. If I was supposed to used the thick head gasket, some body speak up, now is the time to change it! The rest is a piece of cake. I just hope the son of a female dog works when I am done!

Use the gasket that resembles the one you took off -- I still have the extra one that came with the kit, the instruction sheet may say, I don't remember. The head bolts are tightened to 45 ft lbs. Be sure to dip the o-rings in hydraulic fluid before installation. I did not use any gasket sealer on that gasket for fear it would get somewhere it was not supposed to be. It does not leak. Clean the mating surfaces on the head and block throughly. I always tell people to get operators, parts, and service manuals as soon an they purchase a tractor -- not to be arrogant or not willing to give help, but because there is information in them that you will not know about until you study them, also info that those answering questions are likely to forget, we can't remember everything.

CNKS,
I ordered a book, got tired of waiting on it...no it didn't come from here or Binder. I have more in manuals already than some of the machines I bought the books for. I wish there was manual library/archive somehwere online, but too many are in business to sell the information rather than give it away. I think it's rather foolish for there to a thousand spectators out here and everyone of us have a copy of the same manual. I'd gladly xerox the info (if I had it) to share with somebody in need. I have a 3 ring binder that I keep all the printed info in. It accumulates pretty quick.

I thank you for the help you have given, it is greatly appreciated. This job should be finished up today.

Mark, You may find that the archives has a lot of info you could use. I just recently started useing it and I think it is great. Go to the begining of the discussion board and it is the second column printed in blue ink above the last posted item.
