[6pack] TR6 Clutch Master cylinder (.70 vs .75)

[Sally or Dick Taylor]

Bob---It is true that the early six had a larger bore in the clutch MC, thus giving a longer stroke to the slave cylinder. If you trade your early MC for the later one, it should make the clutch pedal easier to depress. Know that the linkage in your pedal box must be without much play, or otherwise it's possible that you won't get complete clutch disengagement. (Also, the tube fitting out of the early CMC may be different than the later one)

If your clutch pedal seems especially hard to depress, like at the last half inch of travel,  there could be another reason for this, such as a broken fork pin. If it is necessary for you to now push your pedal clear to the floor, you may have to fix a couple of things before going to the smaller bored CMC.

Hello List,
I have read (somewhere?) that the earlier master cylinders (,75) vs. later
(.70) provide greater throw or ease of operation.
Is this true and a viable reason to use a .75 in a 1970? I'd like to give my
left knee all the consideration possible. :~)
Thank you.
Regards,
Bob
