--------- I was at the airport this afternoon and measured mine as best I could. It is mounted on the engine which is on the Zenith. I measured inside the nut and read 14 mm. It is a Mitsubishi Electric Corp. My 13B is a 1986.

Yvon.

I'll measure mine and let you know.

I just got confirmation that the ND shaft is 15mm.   From the RX-7 forum archives, it seems like the FB, and FC alternator shafts are the same size, and the FD is larger.  Unfortunately, no one posted the shaft size of the earlier alternators, so I'll be real interested to hear what the measurement of your pulley is. 

 

Thanks,
