This Pioneer Harmonic Balance Repair Sleeve is designed to fit Pioneer brand harmonic balancers. It is a performance/custom fitment type and does not include mounting hardware. The manufacturer part number is HB2124. This item is suitable for use in car and truck engines and is categorized under eBay Motors, Parts & Accessories, Car & Truck Parts & Accessories, Engines & Engine Parts, and Other Engine Parts.
This is a good part for the repair of a worn balancer shaft. I would like to see it a little thicker so as to last longer.
I would advise to replace the balancer at a later date as when this sleeve wears through it will wreak the seal.
