1979 Honda CB750L Gaskets & Oil Seals

For the 1979 Limited, an engine gasket order should follow the repair depth. A single cover gasket suits a localized job; an overhaul set covers several assemblies. Compare named contents before adding individual seals, and identify each cover carefully.

1979 Honda CB750L Limited · Gaskets & Oil Seals Buying guide

Match sealing parts to the repair depth

Cover gaskets, cylinder sealing parts and oil seals perform different jobs. Use the Limited application, the gasket outline and the named assembly together when choosing a replacement.

Parts to consider

1979-83 Honda CB750 DOHC Athena Overhaul Gasket Set Athena overhaul gasket setListed contents include valve, head, base, pan and cover gaskets plus valve seals.View part Honda CB1100 / CB1000 / CB900 / CB750 Clutch Cover Gasket ~ Replaces 11396-425-306 Clutch cover gasketDOHC cover gasket replacing reference 11396-425-306.View part 1979-83 Honda CB900 / CB750 Cylinder Sleeve O-Ring Gasket ~ Replaces 91302-425-000 Cylinder-sleeve O-ring setFour O-rings per set; four specified for the engine.View part

Order what will be opened

The Athena overhaul set includes 16 valve stem seals, four exhaust headpipe gaskets, the camshaft-holder seal and four sleeve O-rings among its named contents. Compare that list with individual items before buying duplicates. Internal shaft seals need their own review.

Keep location and material clear

A rubber ignition-cover O-ring and a paper-style cover gasket are different sealing parts. Match the removed component and reference, and follow the manual for surface preparation and assembly. Do not use a gasket purchase to assume an unrelated oil-seal dimension.

Buying questions

Does the sleeve O-ring set cover the engine?

Yes. The set contains four cylinder-sleeve O-rings, and the Limited application calls for four per engine. That is one four-piece set for that particular sealing job.

Can I reseal only the clutch cover?

The clutch-cover gasket is available separately and specifically includes the Limited application. Confirm the installed cover and sealing surface before ordering rather than buying an overhaul assortment solely for that cover.

Are all engine seals included in an overhaul gasket set?

Use the named contents rather than the word overhaul. The featured Athena set lists valve stem seals and specific O-rings, but do not assume it supplies every crankshaft, countershaft or other internal oil seal.

Not sure which part you need?

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