Timing Gears Generator Models for Harley-Davidson supply the precision-machined gears that synchronise the camshaft and crankshaft on classic generator-equipped Big Twin engines from 1936 to 1969. Stocked by Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, these gears fit Knucklehead, Panhead and early Shovelhead powerplants. S&S dominates the range with high-quality replacements and performance timing gear sets, complemented by options from MCS and Samwel. Correct timing gear mesh is essential for accurate valve events and reliable engine performance, making these components a critical part of any vintage Big Twin rebuild or restoration project.
