Hello Gentlemen,

Just to calrify, the crank sprocket remained securely keyed to the crankshaft and thus kept on rotating and driving the cambelt as intended, while the crank pulley was halted by the resistance of the driven accesories.

Depending on your frame of reference the situation can be described as the crank sprocket spinning relative to the crank pulley or the other way around (Was it Einstein that said everything is relative?). The important thing is that nothing spun relative to the crankshaft.

pcc, I am very relieved that the crank sprocket key held up. The car was only driven a very short distance after the failure occurred.

Thanks for all the contributions.

Regards

Gerrit

P.S. Correct crank center bolt part number for 3.5 DOHC, anyone?
