how to disassemble nf hydraulic lift cylinder

[rogerr]

Hi guys,
wondering if anybody knows how the cylinder from a nf hydraulic lift comes apart? Bought one for my dads tractor and he wants to get it apart for a rebuild. thanks

I have a WP file on the cylinder that is included in rebuilding the Hydraulic pump that was posted on the IH Registry. Email me and I will send you the files.

Just take the hoses off and only the "O" rings hold the ends on. I went to a hydraulic shop to get my "O" rings to be sure the oil won't harm them. They are standard "O" rings.

Geezer,
Can you send me that instruction manual also. I have to do a hydaulic pump also. The pistons I've done before.
Thanks

You got mail

Be careful with the large "O" ring for the canister and the cork washer on the canister rod. I found a centering spring and clevis at a dealer in ME. I don't think the spring I got is correct? It's to long and the bends are different. It might be able to be re-bent? I didn't need it.

Thanks geezer, when you get a chance if you would send that rebuild file to me @ julitron@aol.com.
Thanks

Thanks for the info geezer. It worked perfectly. Dad has the cylinder apart and contemplating making up a new cylinder rod. The old one was pretty bad. We'll see how the rest looks over the next couple of days. The guide you sent would also be a good addition to the registry library. Thanks again

I had to have a new rod made for mine. You should use chromed steel but I just used .500 steel rod. I think they must use under-sized rod as mine was tight going through the hole with the "o" ring. I had to file and sand it down(all I had to turn it was my drill press). The piston will screw off but they are on tight and the guy drilled mine to get it off. I put lock-tite on when I put it back together. No leaks and it stays up with the M&W mower raised.

I can't convert the repair files to Adobe(PDF). If someone can convert them to PDF I would like a copy. Thanks.

Geezer,

If you will email that file(s) to me, I'll give a go at converting to PDF.
