990725 Drive gear shaft, oil pump

This oil pump drive gear shaft is a vital component for maintaining the health of your 1990s Sportster engine. Designed by MCS to meet original equipment standards, it replaces OEM 26488-91. This shaft is specifically for 1991 to 1997 Sportster models, covering the early five-speed Evolution era. When you are servicing the oiling system, it is important to inspect the drive gear and shaft for any signs of wear or damage that could lead to a loss of oil pressure. This precision-machined part ensures that your oil pump continues to circulate lubricant effectively through the motor, protecting your investment and keeping your Sporty running strong for years to come.
