Dynamo Fitting Screws Model 7 Dominator

Forums

Hi 

Can anyone tell me the spec of the screws that go through the timing side, through the triangular plate and into the Dynamo body?  There seem to be 2 screws and the other is maybe a rod with a nut inside the Dynamo? 

Seems to fall into a gap between the Main-Smith service notes and the Lucas service notes

Its a 1952 Model 7 with a Lucas E3l 

Thanks Doug

There are 3 studs and 3 long cheese headed threaded round nuts.  I will advise dimensions later but I was just going to order a set from Norvil for my Model 7 as they are listed on their website.

Doug, 

If you have the Model 7 parts book they are shown  on plate TA at the front of the book as parts 104 & 105 (slightly hidden at the front of the timing side crankcase).

Norvil use the same part  numbers D12/966 & D12/967.

Stud dimensions are 3/16 inch diameter & 1.885" long, threaded 32tpi (BSF,  BSCy or UNF) with 0.35" of thread each end. 

Cheese headed nut is 3/8"diameter & 0.56" long.

Hope this helps.

I believe the mounting studs are 2BA.  Remember, it's electrical equipment, so BA is likely to be lurking around
