Hydro relief valve
 

I am waiting on a rebuild for the relief valve on my 1250s hydro unit. Is it possible to use the manual one from my 127 until I get the rebuilt one back?
I understand that I would have to depress it to move the machine if not running. Or would I have to borrow both?

Yep no problem.

Can I change the valves in my 129 hydro and then not have depress them to move it?

Sure can.:beerchug:

Wish someone had told me that before I put it all back together:bash2:

LOL.... you didn't ask! :biggrin2:

Jon's right! Read your signature again, Tim! Lol

If you are going from manual to automatic relief valves, then keep a heads up on parking it so it doesn't roll away!!

Thanks for the info guys. I was wondering what makes these valves tic. Are they more likely to go out under more demand from the pump/heavy use?
For instance i am trying to figure if it went out because i am plowing snow with the tractor now. This seems to put a lot more strain on the machine naturally. Opposed to cutting grass slowly on mostly flat terrain. Or is it a don't worry I will break eventually and you will replace me part?

The typical failures are:

Mechanical Type: Plunger that moves up & down rusts up. Some oil leakage.

Automatic Type: Leaking fluid out the top vent hole.

NEVER heard of a valve failure due to heavy use nor the internals breaking.
