Rebuild or Replace?

[Indygunworks]

This cylinder is probably over 30 years old. Who knows if it has ever been serviced or not. Its the only cylinder that's leaking, but it leaks ALOT. I could probably fill a shot glass in less than 8 minutes w/ how much it leaks. whats my cheapest and or best option here? rebuild repack or replace?

Depends on your use. The pits & nicks on the rod will work on the seals. If low usage, it might last years. Work it 8 hours a day, expect a couple of months. 3 Point backhoe not likely to get a lot of use... Polish the shaft & Repack it.

Will be a very low use item... high use for a few months while I build, and after that it will become a toy.

Any links to where I can teach myself how to repack? where do you recommend I buy the parts? Is this something I should attempt?

I was better served taking the cylinder off and taking it to a hydraulic shop. They had the proper tools needed to open it without damage... and the kits to repack it. You would be too.

Edit to add ... They will be able to help you decide to repack or replace.

Take the cylinder off and check and see what you can buy for a replacement. Some cylinders are surprisingly cheap and can be less in cost than repairs. Your call of course, but if it were me I would remove cylinder and visit a hydraulic shop or two and see what they have to say.

price a good new one ... a cheap new replacement (tie rod style) ... and bring it down to a shop and get a quote on rebuilding ..

even the cheapies should last a long time ...

then consider how much fluid you may go through doing the heavy work and weigh the pro's and con's ... dollar wise and other ...

Depends on if you can find the parts to rebuild it. I have a guy here in Tyler that rebuilds hydraulic cylinders for all the dealers and anybody who walks in the door. He has a very good source for everything he needs, but has said that there are some out there that you just can't find the parts for anymore. My dealer wants a couple hundred dollars for the rebuild kit if I have the newer, updated piston. That's another couple hundred bucks depending on the size of the piston I need. The specialty guy will sell me just what I need from $20 to $50 or do the rebuild for me once I bring the cylinder into his shop for $100 plus parts.

Well I decided to at least try to tackle rebuilding... so far so good. Any idea what I need to measure to order new seals? what type of seals? I am using travelers universal hydraulic fluid if it matters. Here are a few photos... the bore is 2.5 and the rod is 1.5 I have no idea how to piece together a rebuild kit for this cylinder. Any advice you can give as to how to measure, what type of seal ect ect would be greatly helpful.











and the bore looked pretty good also

If you go to some of the seals websites, they tell you how and what to measure.

You will need a good set of calipers, or take it to a hyd shop and let them measure.

You need to know cyl diameter, piston diameter, groove width, and depth, for each o-ring,etc.
