I have a Williams locomotive with a drive shaft that is slipping inside the flywheel to the point that sometimes the motor just spins but the locomotive will not move. There is no binding in the locomotive, as when it does run, it runs very smooth and quiet. I also inspected the gear box to ensure there was no binding.
How do you tighten the fit between the drive shaft and the flywheel on a Williams Locomotive. Is some slip at a high torque OK. I.e. protects the gears/locomotive/motor?

Slip is never good. See if the flywheel has a set screw. If so just tighten it. If not then a CA glue of any epoxy will work.
1/2 drop of water-thin(original - not gel) CA should do it.
It looks like the set screw just holds the flywheel to the motor shaft on the flat key. I will give the CA glue a try. should the drop go in the flywheel well/hole, on the shaft or does it not matter?
Isn't the flywheel on top of the motor??? A flywheel slipping is not good but would not keep the motor from turning the gears in the truck. Maybe your loco is different than the WbB I own.

At the convergence/insertion point. Capillary action should draw the CA into the flywheel... a very tiny bit is all that is needed. CA has a weak shear strength, so if this does have to come apart at some point, it will.

Got it.
I assume that Williams glued them in originally.
Thank you for the help.

I think the older Williams locomotives are different. They have the flywheel on the drive shaft end of the motor between the motor and drive shaft. The drive shaft slips into the flywheel. I have several modern lionel locomotives with the flywheel as you described.

No, it's an interference fit(pressed).

Thanks...I thought I had every version Williams made in early days.....including Lionel powered.....
Careful with that CA!!! Use a needle cut with a Dremel to apply one DROP. Otherwise.... (you can guess what might happen??)
Repair made using many of the suggestions you guys made. Used a sharp X-acto blade to apply a small amount of liquid CA glue and allowed it to draw into the voids via capillary action so as not to apply to much and then gently scraped any excess glue off of the flywheel (there wasn't much). I'll let it sit a while and then will put the locomotive back together to see how it runs.
Thank you everyone for your suggestions and information.
What it your locomotive?
