Dieselguy I think the OP was referring to a system that sees little use or long storage.
Think about how many times you have seen a dump cylinder ruined because the operator left the dump bed partly up to keep it from holding rain water during the off season.
Like I said in my first post I believe my good luck with the slide system is because we use the trailer a lot and the slides never sit more than 2 weeks without being used.
I think my bad luck with the landing gear is because we use the trailer a lot and just wear out the screw jack.
It would be interesting to disassemble one of the cylinders to see what they are using for seals.
By the way Skydrol is used for high temperature application because of its flash point. I don’t necessarily like the stuff but it sure will tolerate temperatures that the 10 wt hydraulic oil will not.

Jay,
BigFoot warranty is 2 years on parts and labor. The hydraulic cylinders are warranted for life.
Keystone manuals say to cycle slides in and out once a week if you are staying in one place for long time. So they are expecting you to cycle in and out a lot.
Unless you see fluid leaking, I wouldn't think it would be the cylinder. You might try turning the value for the bedroom slide to see if the problem is at the pump or the cylinder. With value in turned it should lock out that slide from the rest of the circuits.

Hi
The cylinder can leak at the seal on the piston. This allows the fluid to leak between the two fluid chambers. This results in the cylinder allowing the load to move. At the same time these seals can hold under full operating pressure and leak under low or no pressure. A leak in this location isn’t visible.

Perhaps you can "call a time out" and re-evaluate the problem. My BS METER went off when THEY want to replace 2 cylinders. I know you never replaced both ramp actuators when one leaked, right!

This past week they had to replace two cylinders in the belly for my living room slide outs for creep also.

Just saying, when troubleshooting skills are lacking, changing everything increases your odds. That's what I suspect happens often at dealers.

If my 3800re hadn't had the level-up system already installed, then I would have gone with the Bigfoot system. There is a reason that New Horizons, among a few others, use this system. But I have what I have until it fails... john

I'm on my 3rd mechanic for this issue and the problem has yet to be resolved. My patience and pocketbook are exhausted. If the current mechanic can't fix it, I will cease throwing money down the black hole and look at other options. This problem has really deflated the joy balloon that was my Montana.

Jay,
Because we love Betty, if it's not fixed when you come to Vallecito this summer, I'll fix it for you.

I spoke to our current tech today and he (in concert & consultation with Lippert after testing) have concluded the fix is a new pump to the tune of $1300 just for the pump. That will bring us over $2300 spent on this issue since 2012. It had darn well better fix it. If it doesn't, I'm hiring a shaman with a rubber chicken and juju beads.

They replaced two of mine a couple weeks ago, and NO more creeps.

You may have had 2 cylinders leaking and maybe not. The important thing is your creep is fixed.

I was told they were leaking internally. Now sure how that works. Maybe a bit of overkill replacing them both. Luckily I had an extended warrantee and it only cost me the replacement of the hydraulic fluid. $60.

I had 2 cylinders replaced at the Goshen rally. Lippert did it under warranty. They just said it is usually the 2 big slide ones and just replaced them. You would think if it was easy to replace the seals, they would have done that. They even drove 2 hours to pick up the cylinders at a warehouse.

Twindman: I work for a large manufacturer in maintenance. The days of automatically rebuilding components are being phased out. Production rate, onsite parts inventory, and downtime are constantly at odds with one another. New components are ordered in and we are directed to just swap it out and hope for the best. If you look at the cost of say a 32" stroke cylinder from Lippert at @$225.00 ... $100.00/hr shop labor ... $45.00 for the seals (if they can be had for these cheap cylinders)... larger repair facilities rationalize to just go new. Look at it from this scenerio ... you buy a seal kit and remove and disassemble the cylinder just to find the barrel scored. The kit will do you no good, so you get to reassemble the cylinder and stuff it back in the fiver just to do it all over again when a new cylinder comes in.

I'm really looking forward to putting this issue behind us. Camping season is fast approaching and I retire in April.
