About This Product
MCS 70-tooth black rear wheel pulley for 1-1/2 inch belt. It replaces OEM 40217-79A and fits 1984 to 1999 Evolution Big Twins and 1999 Twin Cam models. The finish is hard-anodised to resist belt wear. This is a direct replacement for the factory pulley. Check your belt tension and rear wheel alignment after fitting. Time the replacement with a rear tyre swap to save labour.
Manufacturer part number: 520124.
