The object of this project is to reduce the amount of spacer required on the crank hub.The new blower hub & timing ring purchased is 1.5 inches,the hub that came off is 3 inches.That would be a total of 3 inches of spacer needed to align the crank drive/blower pulley.I not diggin' that much,puts too much stress on the crank snout.Soooooo,I have the w/p pulley as far back as possible and can reduce the spacer on crank,just need to get a shorter blower snout.Might still return this hub & ring.
