SMC Leveling Jack Rebuilding/Replacement
« on: March 12, 2026, 09:16:32 PM »
Three of the four jacks are weeping/leaking.  I hoping to remove the jacks and have them rebuilt at a reputable hydraulic rebuilder.  Does anyone have experience with this approach?  Should I expect the shop to be able to identify and supply seals.  Is anyone aware of possible sources of new old stock jacks?  Just trying to put together a plan.

Thanks in advance...

No new jacks available. The ones you have are welded together, need a special shop that would be willing to cut yours open, replace seals, then weld back together. Several years back, there were a few shops that would do this, but do not know if anyone is still repairing these. Best bet is to Google SMC leveling jack repair and see what you can find. Good luck!

General Hydraulics in St. Louis, Missouri rebuilt my two front jacks on my previous 2002 Beaver Patriot thunder. They took them apart and put new seals in. Did an outstanding job. You can drive your coach there or you may be able to ship your jacks to them for rebuild.

Thank you so much for the referral. I’ll most likely get them done with your guys since they have the experience.

I ended up buying 4 rebuilt jacks from Beaver Coach Sales over 3 years.  The local hydraulics shop would not rebuild them. one  leaked then another then... should have bought all 4 at once.  Very pricey, high core charges, system still isn't working but i should have it fixed this summer.
