Newmar uses about a half dozen or more slide systems in the way they operate and mount. As an example, my FWS uses chains and a hydraulic pump to push/pull the slide in and out and then raise and lower it.
My bedroom slide uses a single motor with a driveshaft that uses the transtorque bushing to make the two cog wheel drives push the slide in and out.
Lastly, my kitchen slide, uses two motors to drive two short driveshafts with a large cog wheel on the end of each. My bedroom and kitchen both use the same motor that people have had issues with the motor coming loose.
With that said, my kitchen motors are mounted to a small box frame, a little larger than the motor. I had to replace one of the kitchen motors and found it both easier and faster to drop the entire motor frame (kind of cage) that also uses four bolts and nuts, versus dropping the motor and then trying to reinstall in the screws later that have to be perfectly aligned with the driveshaft.
When I reinstalled, I installed the motor in the frame, leaving the four motor bolts just loose enough to move the motor around. I then reinstalled the assembly. Once the motor lined up with the driveshaft, I tightened all eight bolts, which made alignment of the motor easier.
