Solinoid valve

[1963jarhead]

Has anyone ever changed a solinoid valve on there hydronic leveler pump,it's a kwikee leveler on a 2003 Winnebago. The r/r leveler won't go up the last 1/4" and gradually drifts down 2 or 3 inches??????

Thanks John

The Kwikee Level Best jacks are dual acting - the pump puts them down and forces them up - there are no springs involved.

Here's a page with links to troubleshooting and maintenance information.

Could you ram be bent? That's about the only thing I can think of that would prevent it from going full stroke.

If your jacks have external springs, they have probably weakened and no longer pull the rams up all the way.

Not likely a solenoid on the hydraulic pump.

I doubt that a SOLENOID or a HYDRAULIC pump is your problem. It is possibly a check valve, but IMHO more likely a bad cylinder seal.
