I just bought a Roundhouse Climex kit. Unfortunately the plastic gear on the end of the metal shaft is loose and just spins. For this reason no power reaches the wheels, both trucks have the same issue. What glue / adhesive should be used to attache these gears firmly to the metal (steel) shafts?

I don't know if it would harm the plastic or not, but JB Weld comes to mind.

Because it is made of Delrin, a very slippery plastic, no glue will work. What I do is gnaw ribs into the shaft with a pair of pliers, then push the gear onto the shaft. You'll get a feel for how hard. I've done it to turntable motors that take a lot of load and they've held up forever.

Hey shay, thanks for the tip, man. :thumbsup:

I also have a Roundhouse Climax made from a powered boxcab track cleaner chassis and a Climax shell, and it works fine...

...but I have two other boxcabs and one has a similar issue except it's a slipping motor pinion, so I'm gonna rough up the shaft.

I tried the groves in the shafts with no luck. The loco moved an inch or so before they started spinning. Anything else that I can try?

Sorry to hear that...it's failed me only once and that was because there was a crack in the gear I couldn't see. I used it just recently on my 2-6-6-2 combined with some JB Weld and it worked just fine...
