Re: IH 1050A loader leaking down

I would suspect the control valves myself. I had an old IH loader on a 2504 that did the same thing. This thing was totally worn out. I needed the loader at the time, so I rigged a cross brand 2-way valve in place of the IH valve. Problem solved.---This could be your problem also.---If yours is that worn, it could need cylinder and valve work.
Check in your area for hydraulic cylinder builders. They can help.--We have one 20 miles away from here that makes new, or repairs old ones.--- Had them make a new rod for my Case 580 loader. thanks; sonny

These things are super easy to pull apart... about 5 mins to get off and apart! I used the piston as a slide hammer to pull out the gland as it is just in place with a snap ring, not threaded.

Looks like it is a 2" bore, O-ring piston seal with 2 PTFE backing rings.

This cub has had a pretty hard life, and these loaders are as rare as hens teeth.
I am hoping that once I pull this thing apart it is a relatively standard bore, etc so that I can scrounge up the parts to repair.
Baum Hydraulics is a good place to go for parts and help. Once you have the lift pistons apart, call them and describe what you need and they will be of lots of help.
If you are not part of the solution,
you are part of the problem!!!

Thanks for the tip! I'll give them a go if nothing pops up locally.

It looks like the way to go with be to retrofit with a t-style piston seal (Edit: If I do this I need a wide gland t-seal since my o-ring already has 2 backup rings, looks like special order and $$). Looks to be about 6 bucks each, not bad at all. I've got a local Parker dealer and I'll see if they can order it all for me. While I am at it I will replace some of the hoses .. most have been replaced and are pretty good, but two are original and the braiding is showing.

Edit: Do you think it makes sense to replace the backup rings? If not, all the seals are o-rings in standard sizes.. I could buy enough on McMaster to rebuild all the cylinders for about 15$.

Took one of the lift cylinders apart: It looks to be exactly the same as far as seals and backing rings. The only difference appears to be the overall travel length of the cylinder. I should be able to rebuild all 4 with the same components.

I also found a damaged o-ring and backing ring on this lift cylinder, see below. This could't be helping the situation.


I'll take the seals to my local o-ring supply company and spec the all out. My measurements indicate that they are all standard dash sized o-rings. One i've confirmed fitment and tried them I will post a parts list.

My current thinking is that there is no need to upgrade to a t-seal when the current o-ring and backing rings have worked fine for 30 years. Tell me I am wrong if you disagree ;)

sounds like the valves need rebuilding. New o rings. I’d put new o rings in everything.
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.

O-Rings are not expensive and have worked for many years. I see no reason to use another technology when this design may outlive me.

Agreed.

There is a local hydraulic place that I will be visiting on Thursday to buy the o-rings and backing rings. I've got all the orings already sized out and will let you know how it turns out.

I would like to here more about how you did the power steering.

I really need to start a thread on this. I've got pictures and can likely make a quick summary. I's a highly recommended mod. I can steer with one finger !

I would love to see a thread on this, I'm getting ready to do the same conversion this winter on one of mine, would love to see in detail how you did yours.

Quick update:

All is back together. I did end up upgrading to piston-style seals on pistons. All parts were about 20 USD/cylinder.


It seems to hold fine now (but I haven't tested under higher load as my ground is too soggy to drive on right now).

O-ring list:
326: Main piston o-ring: Needs 2 backing rings.
224: Gland to cylinder seal: Need one backing ring
215: Gland to rod seal: Needs one backing ring.
211: Rod to piston seal: No backing rings.

Confirmed that all cylinders use the same parts.

Time to rebuild all the valves, clean and inspect the spools and install new o rings. And cylinders.

Do you have a 3pt hitch with a selector valve?
