 Topic: 190XT Power Steering Cylinder Leaking... Repair?
Posted: 28 Feb 2021 at 5:45pm |
Hey everyone! My 190XT seems to be leaking from what appears to be the power steering cylinder. I noticed some fluid on the ground after I had it running while parked for some time today, it appeared to be hydraulic fluid, and this seems to be holding true. My power steering cylinder appears to be leaking, although I cannot tell from precisely where. You can see a slight dribble-down where the ram comes out of the cylinder, but then I'm not positive that's the spot. Are there any common issues with this? I would assume a seal has become faulty inside the cylinder, but I also know there's a wealth of knowledge here that others may be up to sharing. If it is a seal, while researching parts I think I saw something about a seal kit.. But I couldn't actually find one. Does it exist? If so, is this something an ordinary competent mechanic could do or not?
Thanks in advance!
EDIT: Also, is this something I can put off repairing for a while (unless it gets worse) or will cause harm? Obviously I'd have to stay on top of fluid, but it's a minor leak.

It's over 50 years old, at that age it can be common for a cylinder to leak. Some of the oil might also be running down the engine and hydraulic pump.

Check the line at the bottom of the hydraulic pump, they tend to leak and run down on the A frame near the cylinder also. The ram can be rebuilt by a good hydraulic shop if in fact it’s leaking.

Thank you both! I didn't get around to looking more into it today, but I'll definitely check more into it at a later date.
On a bright note, heaven forbid I need it, I found a seal kit for it. 70255712 - runs about $100. I'll put it off for now.. Might get bored one day and want to mess with it, who knows.
Thanks again!

Thanks for posting the part number for that seal kit. I have some leaks that I have to get cleaned up so that is helpful.

When all of you get your seal kits, beware of the fact you can easily ruin the white Teflon seal that goes around the piston. It has to be stretched almost to the point of breaking to get it on the piston and then into the groove. So, best to soak it in very hot water before installation to help it stretch easier and then once on the piston and in the groove, place a simple worm gear hose clamp over it to squeeze it back into the proper diameter. Leave the clamp in place for a few minutes and then with plenty of grease and oil slide in into the barrel without shearing it off. I also like to have a thin piece of cardboard or a post card to put between the hose clamp and the Teflon seal to protect the seal from any damage from the hose clamp squeezing it.

That is good advice. I've done that very thing in skidloader cylinders I have repaired

i have found on some cylinders that use an internal snap ring to hold the piston in place will create a ridge, so, I use a cylinder hone to smooth it up,, sure makes re-assembly go a lot smoother...

If you have a good vise it is not that big a deal to reseal a cylinder. The steering cylinder is not that big.

@DSeries4 Yes Sir, that's where I commonly go. I just couldn't find a seal kit on there previously. Likely, I wasn't looking in the right spot even with searching.. But I'm sure if I had troubles then others will occasionally as well.
