Gearbox replacement
 
2016 FR3 32DS. Had a gearbox go bad 1 yr ago on the main slide. Now the bedroom slide gearbox has gone bad. I'm thinking about trying to replace it myself this time and I have a couple of questions for those of you who have done this yourself.

I watched this video on YouTube which seems to be the only one I can find that's focused on the gearbox replacement. He did a couple of things I am wondering about.

1. He mentioned you need to have the slide 1/2 out when replacing the gearbox and you have to stabilize the slide with jacks and 2x4s outside. I don't have any jacks, if the slide is 1/2 out and weight is distributed, is the stabilizing needed? The mobile repair person that replaced the 1st gearbox didn't do that.
2. He mentions he loosens all of the cables when taking the chain off. Why do you need to loosen all of the cables? Why not just loosen the chain and leave the cables as is?
3. Do you agree with the slide being 1/2 out as being the ideal location for the replacement?

Thank you in advance for your assistance

Gearbox replacement
 
I am having my gearbox replaced today. Having a mobile RV repair guy coming to your CG site. I have a new gearbox that my dealer back in NC shipped here. We have been traveling without being able to open the slide for several days. It is the bedroom slide.

FYI: We have a Wildcat 5th wheel and are currently at a KOA in KY.

Apparently these gearboxes go all of the time. Also the replacement box should have a serial # that starts with a 17 or higher. There were improvements to the boxes manufactured in 2017 and later. Both my bad ones had 15 on them (manufactured in 2015). Tom, can you ask those questions I mentioned to your mobile repair person that comes today?

5er_tom 07-24-2018 08:53 AM

The new gearbox is a 17. The bad one is a 14.
I will ask him your questions.

5er_tom 07-24-2018 08:54 AM

When I called to order the gearbox my dealer thought I needed the motor also. He said they are almost unavailable, as could not locate one.

5er_tom 07-24-2018 09:10 AM

I asked. He did not really know. Lots of talk about size of slide, etc.

mjessie 07-24-2018 09:11 AM

The questions will be to your mobile repair person as he's doing the work. Thanks

I have a 2015 DS30 and replaced my main slide & bedroom slide boxes in the same week. It was so frustrating, but I'm glad they happened so close to each other.

The bedroom went out first so that was good practice for the main slide. I didn't use any supports for the bedroom and didn't have it in the out position. My mechanical minded friend did the grunt work of loosing and tightening the cables so I can't comment too much on that.

When we replaced the main slide, we did have it out all the way and we supported it using scrap boards and car Jack's. We used a level to make sure it was plum. I thought it helped when we lowered the leveling Jack's first and then leveled the slide.

I now have two failed slide out boxes. Can they be refurbished or are they scrap now?

mjessie 07-24-2018 02:19 PM

Matthew thanks for the info. I doubt they can be refurbished. I found some video online that showed what precisely was failing within the gearbox and there's an internal part that's actually broken. I think they would have to create a new housing and since the boxes only cost about $90 it's probably not worth it.
Just my 2 cents.

If you still have this old gearbox, would you want to get rid of it ?
I think I can look at it and recommend a very inexpensive change for the manufacturer and a possible easy addition to a brand new gearbox to make it last much longer.
let me know if you want to part with it.

Do you have a part number or where I can pick up a spare...are they two different gearboxes one for the main and a bigger one for the living room slide...I have a 30 ds fr3

Kentucky Bob 07-25-2018 07:12 PM

Hello Gomatthew,
I would love to have a broken gearbox to try to do my fix to it. Let me know if you want to part with one or both of the gearboxes,

Itís this one. You can buy either the gearbox by itself, the motor by itself or both together. There is no difference in the parts on the various slides (bedroom vs main slide)

The gearbox is readily available. It is what fails most often. The motor is not. My dealer could not find one.

I haven't personally had any issues with the cables themselves but I went ahead and ordered 1 just in case. The only other issues I've had was the anti vibration foam that goes on the end of the cables. (BAL Adnik Slide Out Anti Vibration Foam - 854266)
I had 1 of them break apart and then over time the cable started to slowly work its way out and get loose. I bought some of those from Dyers and replaced it and tightened the cable back up and so far so good.
I've also had the grommets disintegrate on the outside of the RV so I ordered some of them as well. (Bal/Adnik Slide Out Rubber Cable Grommet)
