K. O. LEE R503 Valve Reseater Kit Hardened Valve Seat Insert Cutter R55V Grinder
This is a vintage K. Lee valve reseater set. The model number is R503 as shown. This came from Andy’s Auto Supply in Santa Cruz, CA which had been in business since 1949. Andy’s was an auto parts store and machine shop that recently closed it’s doors. I don’t know much about this tool kit. As I said above, I believe it is for cutting hardened seats into cylinder heads. I do not know if it is complete or not. The electric grinder/drive is model R55V as shown. I tested the R55V and it powers up and seems to operate smoothly. I hope someone out there is able to put this kit to good use. This is your chance to own the K. O Lee R503 tool kit you have been dreaming about. At a GREAT PRICE! Don’t miss out. The item “K. O. LEE R503 Valve Reseater Kit Hardened Valve Seat Insert Cutter R55V Grinder” is in sale since Sunday, August 9, 2020. This item is in the category “eBay Motors\Automotive Tools & Supplies\Shop Equipment & Supplies\Other Shop Equipment”. The seller is “super-novass” and is located in Santa Cruz, California.
