1999 Dutch Star 3865 slide motor replacement

Trying to replace the Klauber motor gearbox in 1999 3865 Dutch Star. I have the compression nut loose but there are no bolts going through drive shafts. There are set screws on each end of shafts. Will loosening sets screws allow shafts and motor removal???
Any help appreciated.

Welcome to iRV2 , and vintage Newmar ownership

So you have the transtorque bushings loose , and need to slide the shafts to drop the motor/gear box assembly .

I haven't had to do that ; but I believe your on the right track , with loosening the set screws .
I'm working on the coach this afternoon and will look things over and re-post.

You have to loosen the torque nuts. This can be a difficult repair. You will need a large 1.5Ē wrench and a pipe wrench. You will have to loosen the collars on the end of the cog wheels and possibly the set screws in the cog wheels.

Well , I went under the slide today for a look .
What did I learn .
First , make sure your propane door gas strut is in good condition before you go under the cargo door .

Second as Bobby mentioned , the set screws will have to be loosened, and if your shafts are rusty as mine they will need to be cleaned before they'll move through the cog wheel .

Also in case you didn't happen across this members pdf on the Transtorque bushing removal , here's a copy .

Make sure the manual slide locks are on if the slide is in , it may move unexpectedly is it's in and the shafts are removed.

In 2006 Newmar started using motors that have a built-in brake. I don't think you can order the old model from them, at least. My slide would creep out about 3/4-1". I had them replaced at the factory and the slide stays nice and tight against the side of the coach.
