About This Product
Cometic primary cover filler cap O-ring. This fits 1971 to early-1978 XL Sportster four-speed models. It seals the filler cap and stops primary fluid from seeping out. The old O-ring often goes hard and weeps. A dry primary chain wears fast. Check the cap threads for damage while it is off. Replaces Harley-Davidson 37762-52. Replace it whenever you disturb the cap.
Manufacturer part number: R027B.
Fitment
