About This Product
This check valve spring is a small but critical part of the oil pump assembly on vintage Harleys. It is designed to maintain the correct tension on the check valve, ensuring proper oil flow and preventing wet-sumping when the bike is parked. This spring fits 1956 to 1965 Big Twin models and 1937 to 1973 45" Flathead (SV) models. It is a direct replacement for OEM 26363-56. Since only one is used per bike, this pack of 10 ensures you have plenty of replacements for multiple projects or long-term shop use. Keeping your oil pump in top shape is key to engine longevity.
Manufacturer part number: 526363.
