Got the new step motor installed today. The step on my 283TS GTS is a single
step Lippert Series 23.
The only video I found on the inter-web that gives you a clue as to how to get the job done can be found here:
A few notes should someone else on the Lexington forum need to perform a motor swap:
1) The step motor I received from Amazon,
https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1 while supposedly from Lippert, had mounting holes that were a smaller diameter than the 10 mm bolts mounting bolts that came out of the step/old motor. Apparently, Lippert knows that quite a few of these were shipped from their supplier. I needed to drill these out to fit the bolts. If you have to drill the holes out, make sure you drill at least 1 to 2 drill step sizes larger than the diameter of the bolts
2) The video doesn't explain that getting the bolts threaded into the mounting holes in the step is a struggle. The reason to drill the holes out a couple of drill step sizes larger than the bolts is so you'll have a small amount of "wiggle" room in the step motor body in order to allow the bolts to grab the nuts on the other side of the step. The position of the mounting holes was extremely tight and there wasn't much room to get the bolts started.
3) As mentioned in the video, you'll need to snug up the bolts in small amounts as the clearances are tight enough to cause the motor to slightly tilt and jam if only one bolt is tightened at a time.
4) I pulled the fuse for the step motor located in the battery control center box located next to the house batteries before I started. There's no mention of it in the video and as soon as the steps get 12v power they will extend out to the deployed position. I figured I didn't want to be anywhere close to the step when it moved. BTW -- as mentioned by one of the posters in the Youtube comments section, the steps don't need to be set in any particular position when you start mounting the motor and engaging the gears.
The center control switch in the photo I attached in the original post is the step power control toggle. Once I got the step motor installed and operational I found out the screen door is controlling the step deployment. I figured it would be the main door.
Figure about 2 to 2.5 hours from start to finish.
