Hero Genuine Right Crankcase Cover Gasket – HDH11393ACJ000S / 11393ACJ000S | Hero Mavrick 440 | Harley-Davidson X440 / 440X

Anytime the right-side crankcase/engine cover is opened (for inspection, clutch-side work, or internal access), the gasket should be replaced to avoid oil seepage and repeat labor. This is the Hero Genuine “GASKET CRANKCASE COVER RIGHT”, part number 11393ACJ000S, also seen in trade listings as HDH11393ACJ000S. 

A fresh OEM gasket helps maintain a proper seal between the mating surfaces, reducing the risk of leaks, messy oil stains, and uneven sealing that can happen when old gaskets are reused or when generic sheet gaskets are cut locally. If you’re servicing a Hero Mavrick 440, this gasket is explicitly listed for the Mavrick on Hero’s official store and is widely mirrored by major retailers with the same part number.
