Girling Master Cylinders

[Lin]

Hi folks,
I have a couple of old girling master cylinders in my parts collection that I cleaned up nicely before I put them away, but I did not mark their shaft size. The number on the casting of each is 310360 D2, Can anyone tell me what size the cylinders are?

Thanks!

Lin - You mean bore size? Surprised they're not marked "75" or "625" or some such cast-in marking.

Hi Steve,
yes. I mean bore size. I have a few others that are marked ( 3/4” and a 5/8”), but these two don’t have any obvious bore size markings. Both are clearly marked as Girling.

Thanks, Rick.
how did you find them? I cannot tell from their web site - do they sell these products that are listed in their catalog?
When I didn’t get a quick response I did measure the bores and they were 5/8” just as your research confirmed. Thanks so much!

I just Googled the part # and came up with that site. Think it's just a catalog.
