1981 Honda CB750F · Gaskets, Oil Seals & Hardware Buying guide

Match the gasket package to the covers and joints involved

An individual cover gasket can suit a focused repair, while the Athena bundles cover a broader group of joints. Choose from the actual package inventory, then assess the separate shaft-seal and fastener purchases.

Parts to consider

1979-83 Honda CB750 DOHC Athena Overhaul Gasket Set Athena overhaul gasket setSet 18-0109 lists the 1979–82 CB750F and provides an itemized inventory for a broader engine repair.View part 1979-83 Honda CB750 Athena Gasket Set (Top End Set Only) ~ Replaces 12391-425-010 Athena top-end gasket setSet 18-0432 is offered for the 1979–82 CB750 models, with individual gasket and seal references listed.View part 1979-83 Honda CB750 / CB900 / CB1000C Engine Oil Seal Kit Six-piece engine oil-seal kitKit 01-9034 covers the tachometer drive, clutch arm, crankshaft, oil-pump shaft, countershaft and shift shaft.View part

Related parts: Valve-cover gasket, 12391-425-010 · CB750F engine bolt set · Clutch-cover gasket, 11396-425-306

Use individual gaskets for a focused cover repair

Valve-cover gasket 12-1002 replaces Honda 12391-425-010; clutch-cover gasket 12-5042 replaces 11396-425-306. Identify the joint involved and check the larger package’s inventory before adding the same gasket separately.

Plan fasteners separately from sealing parts

Engine bolt set 73-0147 lists 54 bolts and three Allen keys for the 1979–82 CB750F. Compare the particular fasteners needed for the work rather than treating a gasket or oil-seal purchase as a bolt kit.

Common questions

What additional coverage does the overhaul set provide?

Both Athena sets list valve-cover, head and base gaskets, four sleeve O-rings, four headpipe gaskets, sixteen valve-stem seals, an ignition-cover gasket and a camshaft-holder seal. Overhaul set 18-0109 additionally lists oil-pan, generator-cover, left-crankcase, clutch-cover, three-section oil-pump and starter-cover gaskets. Compare those extra joints with the planned repair before choosing it over top-end set 18-0432.

Do I need a separate camshaft-holder seal with either Athena set?

Both sets already list camshaft-holder seal 18-7066. The separately offered seal replaces Honda 91311-425-000 and is the triangular rubber piece with rounded corners. Add it separately for an individual repair or another stated need, rather than automatically duplicating it with either bundle.
