Amazon thread size enquiry

red122 · Aug 22nd, 2020, 12:31

Just a couple of queries if anyone knows the answers that would be great thank you .

On the late amazon dual circuit callipers what is the thread size where the brake pipes locate in the calipers?

On a regular B18 engine on the side of the block where the dynamo sits in the cradle with 3 bolts what is the thread size for said bolts please ?

Thanks in advance !

R122;

3/8X24 UNF ...but triple-check to verify! See also: https://www.sw-em.com/brake_notes.htm

Three bolts which secure dymano bracket to engine are 5/16-18 (UNC) X 1" ...when using "soft-mounts"...without "soft-mounts" 3/4" will do...

Cheers
