I have a New Holland L190 skid loader that I think one of the wheel motors is leaking badly. Is it possible to repair one of these motors at home?

Depends on the style of motor and what is leaking.

Shaft seal may be a do at home.

Worn motor leaking internally may or may not be repaired at home. Some styles of motors require precise bearing preload which if very difficult for average person to do.

Thanks oldnslo, I was afraid of that. They want real money for one of those motors:censored:

Find out if there is a kit? Talk to hydraulic shops about it, not just the dealer. In fact, that would be the last place I would personally go, except to get information.

Often there is wear beyond just a seal and it's best just to bite the bullet and buy new. Pumps and motors are a major expense! Often, no way around that.

I snapped a shaft on a parker motor. After pricing the shaft,seals & 0 rings it was basically just as cheap to buy a new one. Since I did not know if anything else was bad and what caused the shaft to break.

I’ve had the motor on my zero turn apart. There’s a seal in the shaft end and a few other o rings in that motor. I don’t know how yours is constructed. If you’r motor is the same as mine was make sure you scribe a line down the case with a square before you take it apart because there’s a bunch of alignment critical plates. What’s your experience wrench turning? If your an oil changer and that’s about it than don’t do it. If you could tear down a engine and put it back together you’ll probably be fine.

I would say that I fall somewhere in between an oil changer and an engine rebuilder. However, I will say that I have successfully torn down a number of engines.

I suspect I will be looking for a reputable rebuilder for this project.
