Looking for Williams by Bachmann E7 part

Try looking for a Williams parts person as they may have your part. Parts from Williams also fit Williams by Bachmann.

Or you can try a Lionel or MTH replacement coupler for your Williams engine.

I had problems with some of my Williams engines and use a nylon strap to keep the coupler closed on the engine, mainly GP-9's and early F-7's had that problem.

I don't really need a replacement coupler, the coupler is just missing a spring.  Is there a Lionel or MTH spring that would be a good replacement?

The spring that goes underneath the couple T-bar ?

Thanks SPSF, that Lionel spring might work.

I need to replace a spring that keeps a non-operating coupler centered (there's no t-bar, the coupler is kept centered by the pressure of the spring).

MTH is the same.  Try one of the sellers on the forum.  They will have it.
