1982 Honda CB750SC · Engine Parts Buying guide

Build an engine order around the repair

An oil change, a clutch-cover repair and a top-end rebuild need different parts lists. Choose the opening you will disturb and the dimensions you have measured before adding larger kits.

Parts to consider

Honda CB Oil Filter ~ Replaces 15410-426-010 Paper oil filterStock-type paper element for the original filter housing. O-rings, spring and washers are separate.View part 1979-83 Honda CB750 DOHC Athena Overhaul Gasket Set Athena overhaul gasket setIncludes head, base and cover gaskets, 16 valve stem seals, four exhaust gaskets and four sleeve O-rings.View part 1979-83 Honda CB750 Piston Ring Set ~ Standard Size Standard piston ringsRings for one piston. Four sets service all four pistons; select after measuring the bores.View part

Choose the extent of sealing work

An overhaul gasket set covers more engine openings than a single cover gasket. Its listed contents include valve stem seals and exhaust gaskets, so compare what is already included before buying duplicates. A separate oil seal kit serves different rotating shafts.

Measure before buying internal parts

The ring choices include standard, plus 0.25mm and plus 0.50mm sizes. Each ring set serves one piston. Confirm the final machined bore and matching piston size with your engine specialist; a worn bore is not a reason to choose a larger ring by guesswork.

Engine Parts questions

Does one ring set cover the whole engine?

No. Each listed ring set supplies one piston. Servicing all four pistons needs four sets in the correct size; measure first and keep each piston matched to its bore.

Which filter hardware should I check during an oil change?

Inspect the O-rings, spring and washers for the filter arrangement fitted. The paper element is separate from these service pieces, so add replacements only where the existing parts need renewal.

Can I use later Nighthawk engine parts?

Use the exact early CB750SC application and the part reference for your engine. The Nighthawk name spans different designs, so model name alone is not enough to establish interchange.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
