M-Tec/Lippert slide spur gears-help!

Good afternoon,
I have a 2011 Blue Ridge 3025RL which we bought used about a year ago. We have 2-3 teeth broken on one of the spur gears so that the two sides are not coming in evenly and we periodically hear loud pops. We can push it out while someone starts and stops it with the switch, but it never makes full contact.

We had our mobile RV repairman out and both he and us thought it would be a relatively simple matter of ordering a gear pack and replacing that side. We found out that we would need to buy an extra set of spur gears since they have changed from 2” to 2.5” and we would need to switch them out to fit our system but that was no big deal because they are cheap. Now, however, it has turned into a much bigger deal.

Apparently our system was originally manufactured by M-Tec which Lippert bought out afterwards. They are now telling our repairman that they no longer manufacture or sell the original M-Tec spur gear that is “obsolete.” He has made multiple calls to Lippert who insist the only solution is to replace the entire hardware system under that slide which is extremely expensive and labor intensive. No matter what search parameters any of us use to find M-Tec spur gears we are automatically directed to Lippert and eventually to their directions on converting to 2.5” systems.

I was wondering if anyone else has had to deal with this or has any information on the compatibility of Lippert and M-Tec spur gears. We are frustrated beyond belief as the difference in the two repair scenarios is literally a couple thousand dollars. How can they just buy a company and shut down the production of parts that their own customers need? Any assistance, information or suggestions are appreciated.

I can't find much about the M-Tec system, but RVupgradestore.com has several different gear packs of different sizes.

Is there any way you could post a few pictures of the system and the affected gear?

He just sent me a picture of the gear removed. The inside is not hexagonal like Lippert’s stock gears so we can’t just interchange them, unfortunately.

Does that gear have a hub on the opposite side?

Can you give me the OD of the gear and hub (if it has one) and the ID of the bore?

You could also try calling RV Salvage and see if they have any of them.

There is no hub on the other side. He said the OD is about 1 5/8” and the inside is about 5/8”

I'll do some searching for one, but you should call RV Salvage and see if they have one in the mean time. You may get lucky and they have a few in stock.

Yeah, after you suggested that I printed out a list of them. Is there a specific one you suggest?

One other possibility would be to find a quality machine shop and see if they could repair the gear. It would require welding - if the gear material allows that - and then re-cutting the teeth. Wouldn't be cheap but a lot cheaper than the replacement Lippert said you'd need.

That’s something I hadn’t thought of. I know our repairman has had parts machined in the past. I’ll mention it to him. Thanks.
