Is there a puller for the serpentine pulley on a Delco 35si alternator. I want one that goes around the ribbed portion of the pulley itself. A split or multi-jaw puller damages the fan so I want to be to pull against the pulley itself.

Bust nut loose.
Run nut down. smack with hammer while holding pully

If it aint poppin loose order a new one.
Use never seize so the next guy can get it off.
I won't waste time trying to remove those.

A customer can buy 3 pully's in the time it takes to remove one.

Seems like most of the time the nut siezes solid and removes most of the threads. If I can get the nut off without destroying something then I use a big three jaw puller if the pulley still has enough meat left because it's easiest, if not then a bearing splitter and a press does the job. All in all I have about a 50% success rate and about half of those the alternators puke within 10-15k. Needless to say I try my damndest to sell a new alternator rather than waste that much time.
