Master cylinder I.D.
Okay, I'm ground up rebuilding my '73. Just rebuilt the calipers and was weighing my options with the master cylinder, rebuild it or buy a new 19mm one. The one that came with the car when I bought it (basket case) was a little dirty, but didn't show any signs of leakage. I "ASS-UMED" it was a stock 17mm one, and opted to go ahead and buy a new 19mm (Pelican Parts) one, instead of rebuilding the old one. Now comes my question: Is there any way of Identifing a 17mm master cylinder from a 19mm? If it's what I think it is (a big 19 cast into the bottom of the M/C body), then it appears that I now have 2 19mm master cylinders. After a little wirebrush clean-up on the old one it looks exactly like the new one I just bought. If this is the case, my next question is: Does anyone want to buy a slightly dirt, none leaking, used 19mm M/C? because I appear to have a spare now.

You can measure the bore of the m/c to see what it is: 17mm = .66 inch (called 5/8), 19mm = .74 inch (called 3/4) and the big one 23mm = .90 inch (called 7/8). Good luck.

So, I guess there's no way to know what size it is just by looking at it.

The spare M/C from my '70 parts car has a clear "17" stamped on the bottom of the body, just forward of the mounting flange.
I don't know "for sure" it's a 17mm, but it seems reasonable to assume so. In which case you probably have two 19mm -- lucky you  .Tim |
