HWH Leveler Replacement Parts

I need to replace two hwh hydraulic solenoid valves for my levelers. I was able to find only 2 sources to get them, one was HWH factory and the other was the authorized distributor in Elkhart, IN. Of course, the pricing is exactly the same from either source and the factory would need 2 weeks to build them, whereas the other has them in stock. I was shocked at the price they put on these solenoids, $188 for the small one and $222 for the large can, plus tax (7%) and shipping ($10 - $15). I don't believe this is fair pricing, but given there are no other choices, not much to do about it but pay.

    If you're handy you can rewind your bad ones. The cover just unscrews to expose the copper wire winding.

    Thanks for the reply, that number is for one of the 2 sources.

    The problem with the one of the solenoids is with the needle valve assembly (I suspect) Jack is slow going down and up and sometimes will not retract without a little help. Checked the coil resistance and the voltage to the coil, both are okay.

    1. HWH will rebuild for about 1/2 the cost, but you must get Auth before you send it and you must send in your solenoid for rebuilding.
    2. I have NEVER had a needle valve slow the extension and retraction process. The odds are you have a defective seal inside the cylinder. open the manual release T handle and see what happens. If it still EXTENDS slow, then rebuild it. IF it extends normal speed but retracts slow, replace the cylinder. Doug

    I had a similar problem with my jack solenoid valve and it was simply a little debris that lodged in the needle valve. The shop removed and cleaned...all was well after that.

    I don't have the HWH but the principle is the same.

    doug is right.
    open the solenoid to one jack at a time, and see if the jack extends and retracts ok.
    it will go down, and right back up. if it does not. its the cylinder.sometimes there is a groaning sound with the process.
    the solenoids are normally full open or full closed. if it had debris in it, the jack will leak down. that should not affect extend.

    You can remove the solenoid, then unscrew the needle valve. Soak the assembly in a solvent, blow everything out and reassemble.

    HWH sent me rebuilt ones. I then send my old ones back for credit.

    Download the service info from hwhcorp.com Great info in the manuals.

    DO NOT do this unless you have replacement O rings for the solenoid. Removing the solenoids usually destroys the O rings. If not destroyed it cause hairline tears in the old seals. As I stated, HWH only rebuilds YOUR solenoids as they do not have rebuilds in stock anymore. Doug
