Honda CB Engine Gaskets, Oil Seals & Hardware

Honda CB Gaskets and Seals for Reliable Engine Repairs

Engine gaskets, O-rings and oil seals keep oil inside the engine while preventing dirt and moisture from entering critical areas. Heat, age, repeated disassembly and hardened sealing materials can lead to leaks around engine covers, shafts, oil passages and mating surfaces. Replacing the correct seal or gasket during service helps produce a cleaner, more dependable repair.

This collection includes Honda CB engine-cover gaskets, complete and partial gasket sets, shaft seals, valve-related seals, O-rings, sealing washers, plugs, fasteners and other engine hardware. When completing more extensive work, browse our piston and ring sets and Honda CB valvetrain parts for related internal engine components.

For timing-system service, see our camshaft drive parts. Replacement covers and related exterior components are available in engine covers and accessories. Honda changed gasket shapes, shaft diameters, bolt patterns and sealing arrangements between models and production years, so use the My Motorcycle selector to narrow the results before choosing components for your repair.
