Resivor tank leaking on the slide out pump?

[bsldallas]

Called Lippert about 2 years ago. the o ring on the tank is leaking my hydro fluid out (atf). It is a plastic tank that goes to the pump (pump steel). Lippert doesn't sell parts/make this unit anymore. Just brain storming on rvt that I might could use if I can't find the proper o ring. It's a Keystone so I'm sure there are a lot of them out there. Any info would be helpful. B/c I'm going to repair it after Labor Day (got 2 go 2 the lake).

I've had several of these, but never heard of your problem. If it's just the O-ring, you should have no problem sourcing the correct size. I have one now (on a 2005 Keystone), so I could have a look if needed. Sight unseen (if the tank is damaged), I think you could, at least temporarily, use another tank and plumb it in. It only needs a positive supply of fluid to the pump. You might try finding one in a wrecking yard.

The slides are 100% hydraulic. Even the back-up requires the hydraulics to work. The back-up only helps if you have no DC power to run the motor, or if the motor quits. It works with a cordless drill/socket (had to do this on an older unit with a bad motor). The only fluid leak I've had was a loose coupler on a hose.

Lippert redesigned the pumps, and discontinued the old style pumps and reservoirs. Lippert's official answer is either replace the pump assembly (nearly a thousand bucks), or remove the reservoir, clean it really well, and then reassemble the tank onto the pump using a high-quality RTV silicone. Let it sit at least 24 hours before adding any fluid into the tank.

I work at a Keystone dealer, and have run into this problem before. The silicone trick usually works pretty well. It's not an o-ring issue, I think it's the tank distorting its shape over time.

Thanks Casey.

Do you know when they updated the design? What year model did they start?

[bsldallas]

Thanks Dmax and Casey. What type of silicone do you use? This was about the same thing Lippert told me. They said do away with the o ring. My dealer is like well we sell an upgraded one. I don't need a new one just don't need mine to leak out. It done it 2 years ago and now 3 times this season.
Thanks Brad...

I can't recall for sure when they changed...it's been pretty recently. Around 2007 I would guess.

Just use good high-temp automotive gasket style silicone, and let it cure overnight before adding oil. I'd leave the o-ring in place myself.

Thanks. Guess that's one more thing to add to my list of things to keep an eye on.

[bsldallas]

Thanks I'll do and post a follow up. I'll give it 24-36 hr to cure.

Ok did the above instructions (twice). Did the first time with small bead, second time with a glob of RVT. It has not leaked yet. I promised an update it just takes time to see if it will leak or not. Thanks for all the info. :D

Thanks for the update!
