The pulley fits onto the shaft with a tapered sleeve.  If the sleeve is missing, the fit on the shaft will be very loose - the hole in the pulley itself is tapered and at the large end is about a half inch larger than the shaft.  If the sleeve isn't there, that would look like a totally toasted pulley when in fact it may not be that bad.  I think the pulley is cast iron,  I don't think it will weld very well.

If Sante Fe Springs is a bust John Leslie gave a recommendation, "Vance Butler.  Mechanics mechanic!   Acres of engines and transmissions.  619-672-7009"  in a suburb of San Diego.

I don't know anything other than what he posted in the quotes above.

Hi Bevans... The sleeve info is well received, It now makes a little more sense that the fit could possibly be that far off. Again, your correct, the pully is cast Iron. I am heading over to the parts guy and if successfull, will drop the kids off at the Santa Fe pool for a few hours.

by the way, the people in Santa Fe are super friendly - the employees at Starbucks, the security guards and curious random people - it has been a fun place to hang out.

Bob is the foreman at Ironman. Great little shop, clean, organized and busy. Anyway I was able to get the assembly and the gasket but no pully. I am going to talk to Vance and hopefully the pully is close at hand.

PS. Bob must have travelled with a bus full of kids as he gave the part no charge Smiley I am telling you, I love Santa Fe Springs!!!

      Here's hoping that you get "final fix" soon, easy and (reasonably) cheap!

The pully is a little more difficult to get than I thought. I have Vance and Don looking for it but no luck at this point Sad

I wouldn't be surprised if it isn't a MCI specific part, you could try calling MCI to see if they have one.  When I had the problem with my alternator pulley, they had one - they just didn't have the inner splined hub, which was what I needed.

The MCI part numbers are 7F-3-50 for the engine pulley and 7B-3-263 for the tapered sleeve.  What I would do, actually, since I have a machine shop handy, is see if I could fix the pulley you have.  I'm thinking clean up the bore and make a new tapered sleeve or similar.

  So I take it the alternator drive pulley is kind of a maintenance item, something you should put a wrench on occasionally?

There are 37 different pulleys for that drive get the numbers off the pulley if it starts with 51 it will be a DD pulley and a DD dealer can get one last one I bought from WW Williams was a 175 bucks 

good luck

I could not quite make out the number on the pully but it is obvious now that it is the same number as what Bevans had mentioned. It is also MCI specific as that is why the engines in Bob's yard did not fit.

I will call Luke today.

Mr. Fairchild good to see you around. And your absolutely right id it's MCI specific it's most likely that Sam would have it if anyone would.

BTW I've tried calling you several times. Your a hard man to get a hold of.
