I have a Koyker KB60 backhoe that has the swing cylinder leaking. I'm thinking of replacing the seals myself. Can anyone advise me on the degree of difficulty in doing this. I have a pretty complete workshop with all the typical types of tools, but I was wondering if any special tooling is required. All advice would be greatly appreciated.

they are not that bad to do make sure that the ram is not bent if it is a hydro shop is next. I would measure seals first and make sure they match the replacement seal sizes, unless you are sure the replacements are right before ordering.

Thanks David. Guess I'll give it a try.

Seems like I read on this forum one time, that you should heat the seals before trying to install them. If I remember correctly, you can warm them in oil to make them a little more pliable.

Guess it won't hurt to warm them up first. I'll do that, thanks.

I replaced the seals on my Koyker loader last summer, it wasn't hard at all. I heated the seals following instructions I had read on the internet. I know I did it on the kitchen stove, it was either a pan full of water or a double boiler with hydraulic fluid in the top, I can't remember.
The hardest part was getting the gland nut off, it's a lot easier if you crack it with the cylinder still installed so you have something to turn against.

Good point, I'll remove the nut before removing from the tractor.
Thanks.

HELP
Well I removed the hydraulic cylinder from the backhoe (KB60).
I have it on my workbench and have removed the flange nut and loosened the threaded insert, but for some reason I cannot pull the ram out of the cylinder. It seams as if the piston is hitting something inside. Anyone have any suggestions?

Well, I looked it over a little closer and discovered that there is some sort of split spring clip, partly visible from the end of the cylinder. As far as I can determine there is nothing to grab hold of to remove it. Any ideas anyone?

A sharp, angled pick or two will get that out.
