I have an original Williams (not WbB) from 2004. The spur gear inside the rear truck that mates with the worm gear that comes down into the truck from motor is mounted on a splined axle shaft. That same axle shaft has another gear mounted on it which delivers power to the wheels of that truck.
My problem is that the spur gear seems to be slipping occasionally on the the splined axle, which means the gear is spinning on the axle without turning it, which means the wheels aren't getting an power.
Everything is lubed up fine and there is no binding anywhere - I know the grease in these trucks can harden up and that is not the problem.
1.) Does anyone have an idea about how to keep the spur gear from slipping on the splined axle? Maybe clean out all the grease and superglue it?
2.) If I need to replace the truck, does anyone have a source of original Williams F3 powered rear trucks?
3.) Will a Williams by Bachmann F3 rear power truck fit an original Williams F3 worm gear, truck frames, coupler attachment, etc.?
4.) If yes to #3, does anyone know where I can get one? The Bachmann parts website says they are out of stock (and it looks like since 2015, so I'm not expecting them to restock.)
Thanks,
Matt
