HWH Solenoid

[Zonkpdie]

Where would I find a tool to remove a slide solinoid from a HWH pump on a 2006 Winnebago Tour?

What kind of tool do they use to remove it?

Thank you,

Thank you,

See if this site gives you some needed help: HWH Service Manuals

You could use a large pair of channel lock pliers. They simply unscrew from the manifold

if its like what i have you can do it by hand .. and most say to do it bye hand

I took mine off with channel locks because the dealer had replaced O-rings and over tightened the slide solenoid thus crushing the O-rings. On mine it was 5 O-rings. I called the factory and they said to only hand tighten. Replaced O-rings as advised and no more leaks.

I had to replace all 4 jack solenoid valves on my HWH 325 system. The bodies easily screw out using channel lock pliers. The problem I had was removing the valve seats from the manifold once the solenoid body was removed. They were stuck big time on the o-rings lands. This valve seat must be removed and is part of the total valve assembly that must be replaced.

After struggling with the seat removal and the fear of damage the manifold I made the tool pictured below. It is one of the valve bodies than I ground the OD threads off. I could then screw the ID threads on the valve seat and work it out of the manifold.

Your seat may come out with the total solenoid assembly, but if you remove the body and see the needle stem sticking out, you haven't got it all.

Hope this helps.

Contact "Engineer Mike" in the ALPINE COACH FORUM. He made a very useful tool, like a spanner wrench, that fits into the 2 holes in the front of the solenoid. It works like charm and any one with the HWH hydraulic system should not be without it. --Tom
