About This Product
MCS crankcase breather screen. It sits just below the breather valve on 1936 to 1947 Knuckleheads, 1948 to 1965 Panheads and 1966 to 1969 early Shovelheads. It filters debris and manages oil mist. Replaces OEM 25275-36. Sold as a set of five. Fit a fresh one whenever you split the cases or pull the timing cover. A blocked screen causes wet sumping and crank pressure.
Manufacturer part number: 909640.
