About This Product
This 1/4-inch steel ball from James Gaskets is a precision component used in the oil filter pressure valve of vintage Harleys. Specifically designed for 1955 to 1964 Big Twins, this small but essential part ensures the oiling system maintains the correct pressure for engine lubrication. Sold in a pack of 10, these balls are a direct replacement for OEM 8858. Over time, these can become pitted or worn, leading to inconsistent oil pressure. Replacing them during a rebuild or oil system service is a simple way to ensure your Panhead or early Shovelhead continues to receive the steady oil flow it needs for long-term reliability.
Manufacturer part number: 8858.
