Thanks for the information I have a 2004 Endeavor and need the 21 tooth spur gear Lippert # 368967 replaced by Power Gear DN13747 now obsolete and called Adobe who said they could make another for same price. Since this is near impossible to find I ordered. Hopefully this will do the trick for me as well.

I haven't heard of Adobe. However, if they successfully make the 21 tooth gear- and in your opinion it is a successful replacement alternative- please post all details necessary so others can order as well.

I stand by Adobe’s product. What they built me was a perfect fit made of hardened steel. Getting it back on the shaft while keeping the wood key thing in place was a little tricky as there was absolutely no play as it should be. It was perfectly milled to OEM specs. Anyone looking for this part should give them a call.

Can you provide contact info for Adobe? Was there any specific person or contact you used? I have been unable to locate them.
Did they assign a part number to this gear? What was the cost of the part?

Sorry for the late reply.
From my previous post:

Adobe Precision Gear Inc. in Carlsbad NM. They custom made us a new gear out of hardened steel that is a direct match. We sent him the specs and what was left of the old gear. We provided them with the DN13747 part number in case they wanted to make extra and sell them. Cost to us for the first one Rikki made was $284.93. Repeat customers may get a better price as he did quote me a lower number per gear if I ordered 10 but I didnt pull the trigger on that option. Good luck everyone. There number is 575-885-8322.

They make gears for the oil industry and have a great reputation. Turn around was 4 weeks.

- my replacement gear has been in for over 6 months now with no problems. Gear made was a perfect match.

Hi all

Sorry took so long to get back but weather in the Northeast put a damper on fixing the slide out until two weeks ago. The gear from Adobe worked great. We removed the motor and once out we pulled the old gear from the shaft and installed the new one. We had to heat the gear a little in the oven at 200 degrees for about 20 minutes and then knocked it on with a little lube and a little bit of force. Slide the key in place and then reassembled. My wife and I did it together took about 4 hours with a run to harbor freight to buy the gear puller (mine wasn’t the right size) and lunch on the way back of course! The slide out works great in fact we are camping this weekend. Thanks KnjObrien for your original post and I too stand by Adobe’s work they were great to deal with and could be nicer!

Heck, don't stay home. Just leave the slide IN and climb in bed. I have to roll my honey over onto her side but at least we are out n about. LOL My slide is very VERY slow & even stops on the IN mode so until I figure out how to fix it I just leave it in all the time.

Just found this thread in my search for a 21 tooth spur gear replacement. I have a 2004 HR Imperial which has a Power Gear bedroom slide which has a broken gear, which is no longer available. It seems to be more common than I thought.
Described were having a Boston ND 21 B machined to fit or having a new one custom machined. Im curious about the outcome of either approach.
My slide gear failed in 2013, and it failed again this summer. in both cases, teeth broke off. Lippert techs suggested that I have an alignment problem.
Thanks for any inputs,

Dick Lucas. ‘04 HR Imperial

You found your way to the correct post. The one I had made was out of soft steel. The concern with that is it might wear more quickly than the ones made of hardened steel. However, soft steel is much more likely to be able to tolerate shock impacts. The one from Adobe is made of hardened steel according to the other guys. I guess you should just make your best guess as to which suits you best. Mine is working fine for me and it sounds like the ones from Adobe are working fine as well.

The gear we had made by Adobe works great. We installed it last March and used it all season. Actually the slide out seems to work better than it ever has and rides in and out more smoothly. During install we needed to heat it just a bit to expand it in order to slide it on and it was a perfect fit. Good luck!

I’m leaning towards using yhe Boston gear approach. I have a couple of thoughts to run by you. Looking at the drive shaft, the drive gear is centered between the sintered bearings with a couple of steel bushings. If you use the Boston gear as is, you can make new bushings to center the gear rather than machining the hub down to the old gear width. Also, the tooth width could be reduced to the new width by chamfering the edge to the 0.500,width with a 45 degree cut. This would leave more tooth meat and make the individual more resistance to fracturing. The key way would still have to be cut. There appears to be enough space for the gear with beveled edges to make good contact with the rack.

Sounds like your goal is to reengineer to better suit your need. My goal was to duplicate the original engineering.
I recommend that you get the gear in hand, and then evaluate your proposed engineering. I would also locate a machine shop that is willing to do this work beforehand. It took me quite a bit to find someone who had this skill and I am in a large metropolitan area. It's just that this type of machining does not seem to be common at least in my area.

Tindalsj · 10-21-2023, 05:01 PM

Also, regarding the hub. I believe in my situation the hub had other interference so removing it seemed like the best option as opposed to messing with the bushing.

Is the Boston gear “hardened” steel? If not you will be replacing/fixing again later. My wife dove into this project and found Adobe Precision who made the hardened steel gear to OEM specs. It has worked flawless. As someone else stated.. seems even better than old one. Runs smooth, teeth matched up perfect with the track. I didn’t see any way to do an “alignment” on the track and gear assembly other than re-installing the bushings correctly. Good luck on you’re fix. I’m so glad many are finding the gear from Adobe Precision to be helpful. Saved us from taking our old fleetwood to junk yard. Sold it to a neighbor when we upgraded to our Dutch Star but slide is still working great on the Fleetwood.
