Subject: [TR] TR4A Pulley Dimensions

Listers,

Does anyone know the dimensions of the two-part crankshaft pulley for the TR4A?
Mine is attached, and my calipers won’t open enough to measure the diameter.

I am looking to determine the circumference, in order to make timing marks for when I start putting everything back together after the head gasket work.

Cheers,

Guy;

If it's the same diameter as the pulley on the TR3A then
the diameter is 5.5 inches. Ten degrees BTDC can be
marked at 1/2" from the pulley TDC timing mark.
