980036 Spacer, for drive gear and idler gear

These MCS spacers are designed for use between the drive gear, idler gear, and the outer cam cover on 1936 to 1969 overhead valve Big Twins. Sold as a pair, these spacers are essential for maintaining the correct alignment and spacing within the timing chest of Knucklehead, Panhead, and early Shovelhead generator models. They are an OEM-style replacement for part number 25800-36. During a cam chest rebuild or timing gear service, ensuring these spacers are in good condition is vital for preventing gear noise and premature wear. These precision-made spacers provide the exact clearance required by the factory specifications to keep your vintage Big Twin's timing system operating smoothly.
