I mounted the flywheel and the pulley on the 2.7 this morning. The "Z1" mark on the flywheel and the pulley don't line up on the case seam? The marks are off by about 5 degrees.
What's up? - The engine is a '77 USA 2.7 formerly with CIS (now with 40IDA 3C carbs). - Flywheel is an early style with integral starter ring and factory stamped timing marks. - Pulley came off the '75 USA 2.7 that droppped an exhaust valve The dowel pin on the pulley is correctly aligned. The flywheel can only be mounted one way - is that correct? Thanks Eddie |

I found out about this the hard way. I sold a new 914-6 flywheel to a guy doing a conversion. I got a call "the flywheel is marked wrong, I'm sending it back". OK, sorry, here's your money back. After discussing this with some other Porsche guys I found out about the later crankshaft indexing.
