908132 Pinion shaft bushing. std. size

For those working on vintage iron, this bronze pinion shaft bushing is a high-quality replacement for the cam cover on classic Flatheads. It is an OEM-style part that replaces reference 25591-37 and comes in a standard size to maintain factory clearances. This bushing is specifically designed to fit 1937 through 1948 74-inch and 80-inch Flathead models. To ensure a perfect press-fit without damaging the bronze material, we recommend using a specialized tool like the JIMS 978282. Keeping these old engines running smooth requires attention to detail, and this MCS bushing provides the durability and fitment needed for a proper restoration.
