About This Product
Colony head bolt washer set for side-valve motors with aluminium heads. These fit 1940 to 1948 74 inch and 80 inch Flatheads and 1940 to 1957 45 inch Flathead models. They replace OEM 16822-39. Aluminium heads damage easily if the clamping load concentrates on one spot. These zinc-plated washers spread the load properly and help seal the head gasket. Use the correct hardware when torquing aluminium. Sold as a set.
Manufacturer part number: 7710-18-Z.
