Colt Case Ingersoll Garden Tractors

The last few days I’ve been “digging air” with the 648 to get a better feel for it. The advice you guys gave me was on the money! You really have to have a light touch on the main boom and swing controls. Just practicing when I can I’ve already gotten smoother with the controls, so I’m getting there.

I’m a previous post I mentioned I had a leak on the power steering cylinder, well its more that that now. I leaks like a sieve! So the question is where do you guys get seal kits for theses? Do you go to your local hydraulic shop or do you have a place online you trust? Thank you for the help!

Many of the case cylinders are quite simple in design. Will have to take a look in the parts manual. A hydraulic shop should have O-rings and seals.
@myerslawnandgarden Bob is our resident dealer here and may chime in. His online store is casegardentractorparts.com

There is also Brian from Salem power equipment and Bill from Barneveld implement.

Thanks for the information. I’ll start checking around.

@JSinMO I believe @Harry replaced the seals on one of his backhoe cylinders and he was in your position recently. Can you find the embossed model number on the end of the cylinder? Once you find that, finding a kit might be much easier.

I tried looking for the cylinder break down in the parts manual but it appears to have pages missing. So I couldn't see what is all in the cylinder. I would think the power steering cylinder would be pretty basic.

From my limited experience, recently rebuilding five cylinders. I would say find a local shop, take your cylinder apart and take it to the local shop and have them match up the O-rings and seals. Kits are fine but sometimes they give you more than what you need, so the cost is probably more than if you purchased just what you need. I purchased O-rings and seals from a local shop for three identical cylinders and the cost was twenty dollars more than the coast of a kit for one cylinder.

Agreed , when I wanted to replace the seals in the 2 post lift before setting it up I took the head and pistons into my local Hydra shop and told them what it was for Pressure,heat and service rating needed . $55 later for all and I will never revisit it in my life time .

This one is how the power steering system works.

Thanks guys! I check our local shops. I’ll update this when I have some new info. It might be a bit, springtime always leaves me with a lot of irons in the fire!

If the 648 steer cylinder is like the 6018 then when you rebuild it, replace the nut on the end of the rod that holds the piston assy together in the cylinder. There have been many of use with that nut coming loose and causing possible cylinder damage. This had happened to mine. Nut loosened up and cup seals ripped apart.

Thanks for the information. I haven’t looked at the parts book yet to how it’s made. But I will pay attention to that.

Thank you.

I found the parts breakdown. Looks like the nut you are talking about isn’t listed but you can see it on the end of the shaft.

Yes. Use a locking nut. I had a nylock nut available and it's been working great now for the last 2 years.

You are correct the parts breakdown for the PS cylinder is NOT in the manuals. They use the same basic design as the loader cylinder.

My Notes and the nightmare I had rebuilding a PS cylinder on a 6020..

Welded nut!
