Oct 3, 2012 update to the Triumph TR3 project car

Testing Yet Again

It was all-hands-on-deck as we prepared our TR-3 for its next outing.
We built a simple jig to accurately measure our pressure plate's spacing.

So instead we tested the clutch in our driveway, loaded the car and headed to Lime Rock.

On this test date, our engine ran so well (and made so much power) that our clutch began to slip. Errr! Racing a 55-year-old Triumph TR-3 can be exasperating. Still determined to make the Lime Rock Labor Day weekend event, we pulled the transmission and found the problem: We had a mismatch between the clutch disc and the pressure plate. The clutch disc was too thick to work with the ACT pressure plate we were using. Shimming the pressure plate slightly corrected its geometry, enabling more clamping force to be applied to our clutch. Luckily, our problem was solved after this simple fix.

We put everything back together with just minutes to spare, and had no time to go back to The FIRM (our local test track). So instead we tested the clutch in our driveway, loaded the car and headed to Lime Rock.
