Williams B-6 need help

If you can hear the motor running, it could be that the set screw in the flywheel has loosened up.  To remove the boiler, do this:

1) Turn the loco on its back and remove the 2 tiny Phillips head screws holding the front coupler bracket on.  You'll want a set of jewelers' screw drivers to do this.

2) With the bracket and coupler removed, remove the single large Phillips head screw that was under it.  This long screw threads into the bottom of the smokebox.

3) Place the loco right side up (on its wheels) and remove 2 small Phillips head screws on the back of the loco (located low down underneath the cab opening).

4) You can now lift off the boiler.  There is a wire harness for the headlight and smoke unit that you can unplug to free the boiler.

The flywheel is held on with a small metric Allen screw if that is the problem.

Thanks Bob! 

All went well with opening it. I connected the chassis to the tender. The motor and flywheel spin fine and run as they should. The black plastIc transmission is loose where it enters the flywheel. I rotate the transmission by hand in both directions and the drive wheels turn fine with no binding. 

There is a screw head in the flywheel that is tightened, but is not gripping the black plastic part that goes inside the flywheel. 

Is there a way to separate the drive from the flywheel to see if something is broken there, or is it time to put a small amount of super glue in the connection between the black plastic and the brass flywheel?

i appreciate the help.

The flywheel set screw holds the flywheel to the motor shaft.  The plastic insert was glued into the brass flywheel at the factory.  A careful touch with super glue should fix it.

By the way, all Williams, Weaver and 3rd Rail brass steam locomotives come apart the same way: a big screw into the smokebox from underneath and two small screws in the rear of the cab.  They are generally very easy to work on.

You'll be up and running soon! 

It worked! Thanks Bob.

this has been a dry winter. I've seen a number of rewiring jobs, where the insulation had just had enough, but this was a new one for me. You were right, it was easy to work on. Thanks for your guidance.
