[TR] TR6 Cam Degreeing Problems

[tom note]

Jonas, I haven't done this in a while, but I believe that the specs mean that the cam should just begin to open @ 58 deg. and closed @ 18deg. Both measurements taken at 0.050" open. I'm sure others will chime in and correct me if I'm rusty on this.

Subject: [TR] TR6 Cam Degreeing Problems



I’m having some issues degreeing the camshaft on my TR6 rebuild project.
 
It’s a stock replacement cam, Exhaust is supposed to be open at 58 degrees BBDC and closed at 18 Degrees ATDC.
 
So, I’ve got it fully open (maximum lift) at 58 degrees, but the valve closes (0 lift) at 55 degrees BTDC. 
 
Same issue with the Intake measurements.
 
Am I missing something about where/how to measure when the valve is closed?
