Needless to say I am not pleased with Keystone at this point. Now to try and get this into the dealer.

It has taken them them over a month and a half to get the membrane and gearbox delivered. I'm trying to get an appointment set up to take the trailer in sometime next week. I plan on marking the gearbox before I take it in to see if they actually replace it or not.


I'll post the outcome here.

Hmmm, as I understand it the gearboxes just leak some times. If you get a new one, how do you know it won't leak as well? I think the only solution is to install the drip pan under it - at least until the manufacturer of the gearbox makes a change.

I showed the service advisor a picture of my roof and he told me he never heard of slide motors leaking. He sent picture to keystone, awaiting reply.
I called norco (the supplier of the motors) and they are aware of problem. She told me problem is caused by grease heating up in summer. She also told me drip pans are now standard equipment.

The leak is not the only problem with the junk gear box. They use cheap casting which causes the gears to strip, then the slide is stuck. I’m on gear box #3. And I have friends that are having the same issue

My 2018 Montana HC fifth wheel had this issue on ALL 5 slides for me. It was explained to me that the comany that makes the motors and gearbox changed something in the seal where the shaft exits the gearbox. I was also told that they overfilled the boxes with grease and it spills out of the box until the grease/oil level is below where the shaft exits, then it stops leaking.

When I pointed this out on taking possession, apparently I was the first one to notice it. But it bubbled up the roof fabric. They cleaned the fabric, but it then had the consistency of soft rubber, so I was not happy, I made them patch every place where the roof membrane was messed up with patches so that in the future when it rubs in and out it won't tear the now fragile rubber. They did it and I am OK with it now. Oh, and of course, they put the pans on.

I think this is a poor "fix" for the problem. The original gearboxes didn't have this issue. I would think the responsible thing to do would be to have a recall.

New motor and drip pans. Keystone has a repair procedure for the roof membrane. Clean the oil off with alcohol, use a heat gun to heat up the membrane and press it back down, and cover it with eternabond.
They put a 6" strip of eternabond the width of the slide. I can still see the bubble under the eternabond.


The new gearbox has 2 drip pans under it, unfortunately the "technician" who did the work didn't notice that the lower drip pan hits the edge of the slide when it is open all the way. The cables that close the slide are way too loose, you can see the chain drooping in the third photo. Yet they claimed to have opened and closed the slide several times to verify that everything was OK.

Still waiting for a reply from Keystone. I know some people are installing these drip pans themself but on my 269rls bullet it appears the whole facia has to be removed to gain access. I dont see any fasteners,I guess it is glued on.

My fascia has 6 "buttons" across the front edge. You pry them off (by hand) and they expose screws behind them.

An FYI on the issue of loose cables/chains. On our Laredo, the cables and chains on one of the large slides were very loose (sagging). The slide seemed to extend and retract without issue and top to bottom seal contact seemed to be o.k. so I didn't mess with it. One day while retracting the slide it hesitated then there was a very loud metallic popping sound. Turned out the two adjusting blocks on one side of the slide came in contact with one another instead passing by each other. The loose chains had allowed the blocks to rotate to a 45 degrees from vertical. This resulted in a bent adjustment screw and the need to replace the cable. If your cables are looser than the 1/2" deflection recommended (1 inch total) I would adjust them.

I have a 2018 Montana H C ( bought in 2017 ). Has anyone done the repair yourself ? If so how did you do it? Has anyone cut out the bad part and used Dicor? Would that be a viable option. Thanks so much

I just did the install and repair following the Keystone Service Bulletin (KSB) instructions. Mine was in the date range of the acknowledged defective gearboxes, so I was able to procure the necessary parts and did the work myself, and you do NOT use Dicor as part of the process.

I am late posting the outcome of my slide roof problem. Dealer replaced the slide roof and installed drip pan.
While it was there I showed them a soft spot in the floor. Trailer was sent to factory for repairs. Keystone has a plant dedicated to replacing floors on lightweight trailers. They turn out five or six a day. Mine was away four months.

Does anyone know when they made the change on the seal? Were the 2017 models affected?

Seems like the problem has been solved since you don't hear much about it anymore. Our 2018 had the problem but was fixed under warranty. I thought that I had heard that it was in 2018 that they solved the issue so likely in 2019 and newer models you won't find leaking gear boxes. Don't hold me to it...

I wont hold you to it; but our 2019 had the problem. One motor had a drip pan the other didn't.

Prior to "repairing" my slide roof due to the leaking gear boxes, I spoke with BAL Industries. At no charge, they sent me two drip pans. The rep I spoke with also told me that the gear boxes were "overfilled" from the supplier. After the lubricant falls below a certain level, the seals will not leak. She also told me that the thermoplastic polyolefin membrane reacts to the gear oil and other membrane compositions like EPDM do not. Unfortunately, for us with RVs and and TPO rubber roofs, we may never know how long that will be.

So, their only solution was for dealers to hang drip pans underneath the gear assembly. As far as the repair on the slide roofs, that's up to the dealer and Keystone. i didn't want to pursue a long, season ending dealer fix so I decided to do the drip pan installs myself and provide reinforcement covering to the bubbled area (by way of Eternabond tape).

Mine is a 2017 and have never looked to see if it was leaking. I will do so this weekend. I was just wondering what model year they changed the seal type that caused the leaking.

The KSB says: Keystone, Dutchmen, and CrossRoads units with Norco slides produced in 1/1/2017 through 3/31/2018 and 8/1/2018 through 9/30/2018. This is what the “leak” looks like, more of a seep than a leak but it only takes a drop or two.
