Missing screws
« on: 04 May, 2024, 18:49:52 »
1936 B2

Hello,
My bike has lost a couple of screws from the right hand side casings as you sit on the bike. I've attached some pictures of the missing screws in the hope that somebody can please tell me what thread size I will require.

Also, does anyone know a good source for the screws? I'm not to bothered if they're not an exact match, although it would be nice.

Many thanks

Here is the other picture. You can see the holes where screws once were.

I think you will find that Hitchcock's Motorcycles sell a set of 10 Timing Cover screws with the correct fillister head and thread. The Part No. is 90209.
You will have to cut them to length. They're rather expensive, but they do look the part.

Many thanks.

Are the threads for my cases 1/4 BSW?

Surprisingly, they are 1/4" BSCY and the outer ones are 1 1/8" long.
