Are HWH slide solenoids rebuildable?

Lots of places work on hydraulic solenoid. Check with your local NAPA auto parts store for a recommendation. Yellow pages (shows how old I am), etc

This is the first time I've heard of them being possibly rebuilt. What, may I ask, might be the difference between rebuilding one (if it's possible) and, just purchasing a new one?

For $100 difference I’m buying new every time. Rebuilding is a false economy here.

A Traveler, I wasn't asking your opinion if to buy new or have a unit rebuilt but rather HWH was still rebuilding these units...[ moderator edit]

I got all 4 of my solenoids (for the jacks) rebuilt by HWH - it cost me what one new one would have cost. Quick turn around too. They work fine now. If HWH can't rebuild it to their specs, they'll replace with new. They give you options of painting the ones you send in also. I don't see why they couldn't rebuild ones for a slide - I would guess they are the same.
I wouldn't hesitate to have them rebuilt - especially by the manufacturer.
To answer your question I would think they still rebuild them - just have to be diligent in getting ahold of them. I called, left a message and they called me back promptly. Call Paul and talk to him and who to call - He works for HWH and has helped many many people here. http://www.irv2.com/forums/f258/hwh-...ml#post3763251

Is this slide solenoid for a hydraulic slide motor? What wears out that needs rebuilding? the O'rings (looking at the picture)? Is that a common repair?
My slides are electric so I don't think this applies to mine, but interested.

Yes the o-rings and shaft seals but also the electrical windings inside. If you have a jack that doesn't retract (for example) and you keep hitting store, the solenoids will get hot (winding) and eventually the repeated heat will burn them up. You hear on this site of how "it takes an hour for their jack to finally retract" - those solenoids are going to fail early. It should only take a couple minutes max to retract.
I am not sure how the hydraulic slides work (I have a general idea) but the solenoids control the fluid going to/from them.
When I got my bill it was apparent that my windings were ok because they didn't need to replace any of the solenoids.

You may not have been asking opinions as to the new vs rebuilt, but you should ask HWH what the failure rate is of new vs, rebuilt units. For many years I was in the auto and truck repair business. I found quickly that there was a significant difference if failure rate between new and rebuilt components.
New components had a failure rate of less than 1% during the first year of service. Rebuilt components had a failure rate of closer to 20%. In my experience a rebuilder will not pay labor to have a defective part replaced. If it fails under the warranty they give you another rebuilt part period. Given these units are spares in all likelihood any warranty will long expire before you use them.
You should take into account the failure rate when considering whether or not to have them rebuilt. If HWH tells you their failure rate is 1% or less rebuilding is probably the route to go. If they have a 20% failure rate you have to consider whether your time is worth the difference in price.

WOW!! I had never heard of this type of failure rate in rebuilt parts
And, I will rebuild anything I can.
Plus, have NOT had a similar experience with any retail mechanical or electrical Refurb or ReMan parts.
I would submit that if there was a documented 1 in 5 failure in the first year (possibly under the warranty), time to find A NEW REBUILD CONTRACTOR

Unfortunately I didn't have control over who rebuilt the parts. They were purchased through auto and truck parts houses. At any given time each of the parts houses did business with at least half a dozen contractors. They wouldn't give the names of the rebuilders freely. If you had trouble you had to specify No Rebuilt Parts From XXX.
After about a year of fighting with the different suppliers I specified New Parts Only unless the customer specifically requested rebuilt. If a customer did request rebuilt they were informed before the job began that if the part failed the part would be replaced by another rebuilt, and they would have to pay the labor. They signed an agreement to avoid any misunderstandings.
Knowing the potential failure rate, the difference in cost between new and rebuilt, and the fact that replacement labor was their responsibility 95+% of the customers opted for new parts. There were always those that couldn't afford new, so if they choose rebuilt, and there was a problem that was taken into consideration.

hikerdog, thats the reason hwh does not sell pieces to rebuild their assemeblies. they have no control on the expertise of the repair shop. not saying the shops cant do the job, just that if hwh has to warranty it, they insist on doing the reman themselves.
hwh does rebuild solenoids. touch pads, control boxes, and jack cylinders. the rebuilt parts get the same warranty as new, one year, if rebuilt by hwh.
email to Welcome to HWH Corporation. supply the name. address,make model, year, and vin number of your coach. request a rga number to return the part for repair. and a description of the problem.
when hwh does a repair, they only charge for the pieces replaced, and a labor charge the only price they can reliably quote is the cost of a reman part. because they dont know whats wrong with your part..
that total cost is often much less than even a reman part from hwh.
there are cheaper parts available on ebay and amazon, but they dont carry the hwh warranty.

If you're going across Iowa on US80, stop by HWH in Moscow, IA and have them rebuild all your solenoids. I did this and had to pay for 2 hours labor and parts. They do this all the time.
