Hi,

I am trying to find a larger pulley (4.25 inch)for a 60 amp alternator (part

#14185). The pulley part number per my paperwork is 14087007TAY, a GM part

number for a 70's Camaro pulley that goes on the air pump.



Thanks,

Dale

Hi Dale,



The large pulley  - small pulley pro and con discussion has past by here 

more than once.



I have a 3 1/2" pulley on my 60 amp alternator. This was not my choice, it 

came to me that way. It grazes the cowling on my RV6A and I'm sure that in 

short order there will be a need for some glass repair and paint.

I would change it back if that could be done. In this particular case that 

is not an easy option.

My past experiences during the sport racing phase of my past life tells me 

that there is little or no cause for worry about high rev damage to this 

type of alternator. We ran many of these units at well over 16,000 rpm 

without ever playing the change pulley game. The potential HP saving was not 

sufficiently there to recapture and component failure was never an issue.



I for one definitely would not have had the larger diameter pulley by 

choice.



 This opinion was not requsted, just offered.



Jim in Kelowna - waiting for the new governor to arrive.

Dale,

There is a local automotive repair shop that would be able to help you and 

they are very resonable.

Call Jon's Garage and ask for Don Myers at 814-643-4890.

hope this helps

A while back I learned coincidental that the local auto zone had a whole

box of misc alt pulleys from over the years just collecting dust in the

back room.  If you can still carry your alt in, you might get what you need

as a trade.
