Cracked WBB drive gear - UPDATED

I would send them an email anyway.  The person i communicated with was able to provide a replacement part for me.  It seems they have the equivalent of our under the table left over bits.

Replacement is best. No idea who has Williams parts now as I believe both who had acquired them from Williams have now passed and as you have found out Bachman doesn't really support Williams.

If it was mine I would try and solder it together assuming is pure bronze and not oilite.  Then reinstall it with a retaining compound. If you don’t try and close the crack it will bind at that spot as tooth spacing is now different.

If you can get the replacement gear then do that. It’s obviously an interference fit on the shaft. May just be too tight. Measure the bore and find a drill bit that is a few thousandths larger and open up the bore. Use a retaining compound along with the new bore.

Thanks Guys!

I just discovered Northwest Shortline has the correct size brass replacement gear for WBB O scale engines. I may go that route.

Loctite (it has flavors) is good stuff, widely used in the automobile world (and others), so it's pretty effective for our little machines.

I would most definitely go that route!  A new replacement will be far superior to any repair on the existing gear!

I figured I’d better hedge my bets and place my order before providing a link - just in case they only had one left. 😉

The NWSL part number is 2932-6.

They make gears. If they run out they just make more. If you have a special need and can’t find a gear they will make it for you if you have an example or accurate description.

Thanks Pete! That is good information!

@juniata guy thanks for the link.  When you receive the NWSL part and install it, please grace this thread with an update to let us know that it actually worked!

A few may recall some dozen years ago or so the plastic gears on the TMCC Niagaras were failing. Before Mike Reagan stepped up to the plate and had brass replacements made a forum member had NWSL make a set for his engine. New management now but AFAIK their services remain the same.
