Currently running the part #10 from the picture above (part number 11211263516). It has a cracked and chipped on it right beside the key slot. I don't fully trust it, and wouldn't want my woodruff key to fall on my timing chain!

 

Do any of you know about a replacement part that could work? OEM or not, I don't have A/C or anything. 

 

Thanks!

Not quite sure- is this a WTB post?

Lots of us have lots of these kicking around- they're not a commodity.

 

There are 2 basic types- the big heavy cast pulleys, used in cars that

had accessories, (there are about 8 different varieties)

and the stamped steel ones from the ones that did not.  Might 

just be the earlier cars that got those.

The E21 pulley is a 3- sheave assembly, but is stamped, and quite a bit lighter.

Also, if I recall, smaller in diameter, so it runs your accessories slower

IF you use 2002 pulleys on the water pump and alternator.

 

I have sawn off the front 1 or 2 sheaves sometimes for extra clearance.

I'm sure that voids the warranty...

I believe the stamped steel (vs cast iron) pulley is still available for about $94.00 if that's a direction you choose to go. Used ones should be plentiful and super inexpensive though. I installed one of these on my last modified car to save a little weight and for aesthetic / simplicity reasons.

Wonder which model ran the two piece pulley (parts 6-9)?

 

That one would be handy for such things as toothed ignition pick ups.

The two-piece pulley is tii stuff. The keyed portion includes the gear for driving the injection pump belt. Note: tiis with AC had a second groove for the Ac compressor belt.

I installed the lighter weight steel pulley on my 69.  Got it used from a local 2002 owner and had it powder coated.
