Hello and thanks for letting me check in.
I have a used ExMark Lazer Z HP....don't know the year. 48" cut commercial deck.
I have a hydraulic leak on the left pump. Think it's leaking out of the side of the "dump valve".
Nothing in my book about this.
Anyone know if I can remove the dump valve and replace O rings to stop this leak ? I tightened up the main nut on the valve and it really slowed down a lot, but still weeping some.
Thanks, Pete

Hi, Pete

If the tightening of that nut slowed down the leak, I'm sure you're on the right track for a permanent repair. It is highly likely "O" rings (or fiber/Teflon packing washers) is the culprit.

Like Brad though, I'm not real familiar with your brand specific hydraulics, and my opinion is from experiences with hydraulics in general.
