Hydraulic Boots - Why does the outer part of the piston no longer need to be protected?

Postby lyle11 » Sat Nov 21, 2020 9:34 pm

I just finished a Hydraulic Block rebuild. My next step is to install the piston and control valve boots. I have looked at the past discussions on this topic and realize that originally the boots were leather and later they were made out of rubber. I’m all up to speed on that.

What I am wondering is, the original leather boot covered the entire outside of the piston as well as the control rod. The newer rubber boot fits over the control rod and tucks inside the piston but leaves the outer surface of the piston exposed.

Does anyone have any idea why IH would determine that it’s no longer necessary to cover the outside of the piston? I know it’s fairly well protected under the hood. But if it was determined that it originally needed a protective cover, it just seems odd to me that the newer hydraulic block casting no longer has the flange for the leather boot securing wire. So, even if you wanted to install a leather boot you couldn’t secure it without modifications. It seems like they didn’t want you to cover the external piston or use the leather boot.

Thanks

Maybe they thought their chrome was good enough to not need covering and the wiper was adequate at keeping out dirt. Most hydraulic cylinders have their piston rod exposed when expanded .

the piston is cleaned off by the orings when it retracts, the boot over the control rod is to keep the pivot from rusting up

Thanks. You guys answered my question. I have a perfectly good leather boots that I removed from my old block, but I’m going to go with the rubber boot for the piston/control rod. TM doesn’t carry it but Steiner does.

I have used steiners, found the rubber is easy to rip, they are a 1/3 of the price than IH the IH one is more "rubbery" and does not rip

Tim, I would prefer to order from TM and I don’t mind paying triple the price for a USA made higher quality boot.

But, as far as I can tell, TM only offers the rubber boot for the control valve. They offer only leather for piston/control rod.

Unless you are saying the rubber boot they offer for the control valve will also work on the piston/control rod. If that is the case I’ll order 2 rubber boots from TM.

Thanks

steiners boots the rubber material I found just tears and rips when trying to stretch the boot on, I was happy as they were less than $10 but not saving anything as I was throwing them away, gave them a chance, after the 3rd one I had enough, I buy the IH ones, just because TM does not show it does not mean its not available, bought a few like 2 weeks ago at the dealer

Thanks Tim.
I’ll probably just call the nearest Case IH dealer (40 miles away) to get them for me since I need more Touch Control fluid.

BTW, I had ordered the rubber boots from Steiner, and at first didn't realize the larger boot went on the control rod, over the raised block rim, and the smaller one went INSIDE the larger piston...a bit counterintuitive! I think I ended up just cleaning and reusing my old leather boots.

Just to show what I am referring to with the hydraulic block castings here is a photo of the area where the leather boot needs to be secured with a wire or tie wrap. The photo isn’t the greatest but the rusty area is where there is a little flange that prevents the wire from slipping off.

In the newly painted one there is no flange. Unless you cut a groove, as was suggested in another thread, the leather style boot isn’t going to stay in place. It’ll slip off once the piston moves out.

My old leather piston boot was in good shape but oil soaked. I put it in a plastic baggie with baking soda for a couple days and massaged the bag a few times. I read that cornstarch is supposed to soak up the oil but I didn’t have any. It came out looking good after rubbing and vacuuming the baking soda off it. I put a little of my wife’s lemon essential oil on it to soften it up. Then I decided to replace the block due to some cylinder wear. My leather boot looks great but it won’t stay on and I don’t want to try to cut a groove in the casting.

This is how Steiner's boot for the Piston fits. Somehow it just doesn't seem right, though! :?
