Hey All,
Looking for a NON-CRACKED crank pulley for a 1750 SPICA injected motor. I’m rebuilding a 1750 motor and keeping the SPICA injection on it and my crank pulley is cracked.
I’m not sure, but will 2L crank pulleys work?
Thanks in advance!

OK, that’s the pulley I’m looking for! The crack on mine was where the key slot was. I’ll take it if there is no crack there.
Is you water pump new or used?
Thanks!

Remember the 1969 pulleys are marked different from the 1971 pulleys. Alfa change the pump timing mark.

Oh geez, this is getting complicated. I think I’ll be happy if I can just get one with no cracks. I’m building a 69 motor for a 69 GTV.

Let classicalfas do that. The 69's were suppose to be retimed to the newer timing that came in on the 71 models. All the marks are the same except for the pump timing mark.

Fred, thank you for the pulley!

Jim G - Are you saying Fred’s pulley is from a 71 motor? Is there a document that tells us how many degrees the marks should be on the pulley?

I could not tell you with out comparing it to a later model pulley. From 71 on the pump timing marks are the same.

I'm sure Fred knows what to look for.

69 was a one year only pulley.

Wow, awesome! Thank you!

My 1969 parts manual had this pic and serial number for the pulley. The pulley I got from Fred is 105.51 but the last numbers are different. If Fred’s pulley is from a later 1750, will it have the mark in the new location or will it also have to be remarked?

Pete, can you please post the serial number from the pulley? Also, can you measure where the “I” is from the “M?”
Thanks
