After replacing a leaking hydraulic hose on my Simplicity ZeroTurn #1694454, I found the Release Valve on the LH pump will not tighten/close when turning clockwise. It appears stripped, not stopping either direction. RH valve closed as should. Before starting I added a significant amount of 20W-50 oil to bring it up to proper level. I am able to manually push the mower as it is now. I’ve searched extensively with no luck finding if the release valve is replaceable. Anyone able to offer some help/advice? Thanks, in advance. Larry
