Hi all. I am trying to help my dad with his RV and I have a question about how you would go about replacing a stuck jack. The jack system is a HWH hydraulic system on a 99 Allegro Bus RV and the rv has been sitting for a while. I have ran threw HWH emergency instructions on getting the jack back up and nothing worked so I believe the back itself it complete toast as I also removed the loosened the hydraulic hose as well. I got a floor jack under the jack and tried to get it back up but all it does is lift the motorhome and does not go back up.

If were to take this to a shop do they just cut the springs to remove it? I am leaning toward that option but it seems kind of dangerous to cut a tensioned spring.

If you had the supply hose off and the floor jack wouldn't move the HWH jack then the shaft is probably bent .

You could try driving multiple wooden wedges into the spring coils to lengthen them to the point where they can be removed .
Putting wedges in the springs works for installing new ones.

Then pull the jack mount bolts to get it out for replacement.

Hi Eddie! Welcome to IRV2! We're sure glad you joined the gang!

I can't advise you on the jack problem since I have air leveling only!

Just noticed you are kinda new and wanted to say hello!

Good luck, happy trails, and God bless!

eddie, please call me. i can help 1 602 549 3638.
i work for hwh full time, and live in paulden arizona, near Prescott.
the jack probably is bent, and will need to be replaced.
if you can get the AP model number off it or the one on the other side, will be the same number.
i can get you a repair part number for a remanufactured cylinder and springs.

Paul, all of my jacks have different AP numbers. I do have one that does not go up all of the time. Also, one leaked a little when it was extended almost to the max. Where could I get the leaking one repaired and the approximate cost. My system is a HWH 625.
Thanks
Kirby

send a email to service@hwh.com
include name, address, phone number, vin of coach, brand of coach, year and model. this is to register the one year warranty on the repaired part.
also a. brief description of your problem.
they will. respond with a RGA number to send the part under. tracking
the two front jacks are the same, even with different numbers. the two rears will also be the same on either side.. it takes two to three weeks to get the part back. the only price they will quote is for a reman part, since they dont know what is wrong with yours.

Thanks everyone for the replies. Right now I am just trying to get the thing off being the springs are expanded and I will call about replacements. The wood idea is interesting, think I might try that tomorrow and see if I can get them off, I believe I have a bunch of wood shims I can use to try. I am pretty sure its toast so a replacement will be needed but getting it off so the RV can be driven is what I am trying get to now.

cut the springs with a grinder. remove the entire jack assembly if you cant get the cylinder far enough off the ground to remove it.

The nice thing about HWH is that they quote you a rebuilt jack but if they only find a seal or something easy, they only charge labor and parts. I sent 4 solenoids in for rebuild and paid less that what they quoted me for 1 rebuilt solenoid.
I'm going to plan a trip through Iowa and stop to get all 4 of my jacks rebuilt. My buddy got all 4 rebuilt (he sent them in) for 450ish including freight (from HWH).
