Hi
 does anyone know where i can obtain #322-05-02 sideframe.
Thanks

Hi I have an Early Williams reversing unit. Anybody have an non working board or a Schematic on these or know where to find them. A little research has produced that these board are based on a design by Kenneth and David Ott. A sort of simple schematic was published in a 1994 patent. I am looking for the values of the components  connecting up to the HFC4017 Counter chip, see Included Picture components with a ? are the values I am after.
Any Help  is very much appreciated

Thanks

Topic says it all. This model has twin DC can motors with a single diode for DC operation.

Is this how they came from Williams?

Any info on years of production or any Chassis pictures would be appreciated.

If you own one or a similar model please share your opinion.

Thanks

Len, thanks for the reply . This may shed some light on the subject. This is a early William SD-45 here is a picture of two more like mind note the bottom picture.

SD-45 Truck Picture

Hi,
I am trying to restore a Williams SD-45 early (I think) and have lots of questions.
Here are the first.
1. What is the size of the truck Screw?.. 6-32?
2. What is the size of the roller pick up mount screw?
3. When the motor mount is screwed in the chassis with the Truck mount screw is there suppose to be a lot of slop or a little?
4. Where can I get or what can I use for a roller pickup? (Bachmann is sold out)

Many more questions to follow as I progress and learn.

Thanks in advance.
