Lionel 616 Flaying Yankee motor - gear plate screws size | O Gauge Railroading On Line Forum

Hi
I'm trying to restore Lionel 616 Flaying Yankee motor. It's missing some screws on the gear plate and e-unit,
They seem to be the same size (just differ by length) . Can you tell me please what screws size it is ?

( see picture below).

I read some comments about unusual sizes used by Lionel, like 4-36 and 3-48,
but how to identify what i have to order ?

I appreciate your help.

I believe they are 4-36x~3/16 Round Head Slotted screws. Wouldn't hurt to get an assortment of screws to make shipping worth while.

The e-unit should be mounted with a 4x1/4 Round Head Self Tapping screw, but that would be on the other side of the unit, not the one shown. That hole remains blank.

Len Carparelli took over Nyerges fastener business which specializes in these things: http://www.llmodeltrain.com/NyergesBaSList.pdf

Dr. Tinker also has a nice offering of assortments and whatnot:

4-36 x 3/16”, are typical Prewar screws on most motors. The thickness of the side plates, let you use either 4-36 or 4-40, with no ill effects.

Early yes but they went to 4-40 and side plates used larger 6-32
