Clutch master cylinder bore diameter? - SRT Forums

Anyone know what the stock Clutch master cylinder bore diameter is?

If not, does anyone have a spare master cylinder that they can dissect, and measure? Or, if you don't want to spend the time figuring it out, could you send it to me? I'll pay for shipping!

I know this isn't an SRT clutch master cylinder, but this pic should give you an idea of what I need measured.

Just measure the inner diameter of the cylinder bore. I am looking for a fairly precise number. So you'll need a dial bore gauge, or at least a caliper.

I'm looking for a number along the lines of either: .625", .700", .750", .875", or 1.000".

It may not be any one of those sizes, as those are simply some of the common sizes found in the aftermarket.

I'd greatly appreciate it! Thanks!

I have a spare one laying around with a broken push rod. I have a set of bore gauges on order now. Hopefully will be in tomorrow or Wednesday.

Sounds great! I really appreciate it.

I didn't forget about you Chuck, but of course the gauges didn't come in. Maybe next week, if you don't have the information you need by then.

Sounds good! Nor I or anyone else around me has a spare lying around anywhere, so I'll patiently await your results. Thanks for the update!

It measures right around 18mm (.709").

Excellent, thanks! That's about what I was hoping it would be!

Turbo666, if you still want to measure the one you have lying around, please feel free, and we can confirm this!

Not that I don't trust your measurement, ACTman. In fact, I'm sure it's right. Just never hurts to double and triple check things!

I see how it is! Don't trust me then...

Just kidding. It's that "measure twice, cut once" wisdom.

No, really. I mean it. I'm sure your measurement is correct, and who better to know it than The ACTman!
