HWH Leveler re-seal Help

Our internet is quite a bit wonky this past week, so I can't really do much searching here...

We have the HWH system for slide-outs and levelers. One ram is weeping and needs to be re-sealed. We made an appointment in January to bring the rig in April (largest Freightliner service in Norcal), and they ordered a "new" leveler.

I'll leave all the drama out of how we think they put our ordered unit on other "more important" rigs, to get them on the road - we finally went and just got the coach back after it sitting for 10 weeks, waiting for this part...

PLEASE don't respond about Supply Chain stuff...

I know there is someone on this forum that is an EE of HWH, could you please put me in touch with this person?

I need to know if these rams on the HWH levelers have some unique seal, or if I can get the unit off, I can take it to any competent hydraulic shop and get it resealed...?

Thanks - hope my internet gets fixed...

The Kwikee cylinders on our rig are welded and hard to rebuild. But from what I have read on here, most all other jacks out there use common seals and can be rebuilt.

Pull the cylinder and take it to a hydraulic shop to have the seals replaced. Even a welded cylinder can be opened and the seals replaced. I've had two Big Foot jacks reworked to repair the piston seals. Two hour shop time plus material costs.

How it's done - welded cylinder rebuild

Those are good videos. I took a front HWH leveling jack to every shop around here, no one wanted to touch it. I saw someone on here had success at P&H in Jacksonville FL so I took it there. He had it 3 days and I think it was about $150. The issue with HWH is the wire clip that holds the seals in. P&H had designed a jig to get these out. He had a few others there ahead of mine and he said it takes him about a day to do one.

Here is a photo of that little wire clip.

Thanks folks! Great news is my internet is mostly back so I found Paul's contact info - the picture of the clip really helps as well...

Just so it's captured in this thread also (quoted from another thread):

"Paul that works for HWH on this site he is very helpful and got me what I needed 602-549-3638"
