From reading your other posts, and now knowing the year, I believe you have a model 2001 T267SR.
I cannot confirm for sure without pictures of the slide drive system under the camper, but in the 2001 model era Sunline switched from Barker Mfg, slide drive to Dewald. An early build 2001 model, made in mid to late year 2000 could have either.
I'm going on the assumption you have the Dewald posi-lock system. It would look like this under the slide. Take special note the way it is built.
Here is a diagram from another forum member Woodfam
Here are some pics from member Maint1 Dewald system. Take note of the gear teeth on the slide arms and the motor location.
On the Dewald system, they have a motor torque control box that is part of the slide motor system. It is under a small wooden box cover most likely in the front bedroom on your T267SR under the bed. Taking the wood cover off it should look like this, Pic is from Maint1. The black box unit is the torque control.
How do you know it is the motor that is bad? It may be the torque control unit or the motor too? Or a blown fuse or bad auto reset circuit breaker associated with torque control unit that is in the wooden box? Check that out if you have not.
Here is the service manual we have on the Dewald system that was bought out by Power Gear. https://www.sunlineclub.com/forums/d...o=file&id=5632
On page 67 of that manual, is what I believe you have, again if it is the Dewald slide motor drive system and not the Barker Mfg.
Page 81 has phone numbers for Power Gear. Its the place to start. They will most likely not have any idea what a Sunline T267SR is and what it ever had on it. They just sell them to the camper manufactures and they integrate them. If you tell them you have a 2001 vintage Dewald rack and pinion slide drive system, they may be able to help back into the model and parts numbers you need. Be prepared to send them pics of the slide drive system so they can confirm.
If your slide drive does not look like the pics I linked, then please post pics of yours and we can start over on the Barker Mfg system.
Hope this helps.
PS. Please let us know how you make out. It will help others in the future on how to get parts for the Dewald system.
