1979 Honda CB750F · Engine Buying guide

Build a parts list around the work inside your DOHC engine

A gasket set, piston ring set and shim assortment cover different parts of an engine job. Compare the listed dimensions, references and package contents before combining service parts in one order.

Compare gasket and hardware coverage

The Athena top-end set also contains 16 valve stem seals, four cylinder-sleeve O-rings, four exhaust headpipe gaskets, an ignition-cover gasket and a camshaft-holder seal. Engine bolt set 73-0147 is a separate hardware choice: its detailed inventory lists 54 engine bolts and three Allen keys for the 1979–82 CB750F.

Choose from the listed shim thicknesses

The shim kit supplies two each of these thicknesses: 2.30, 2.40, 2.50, 2.55, 2.60, 2.70, 2.80, 2.90, 3.00 and 3.10 mm. It is a ten-size assortment rather than every intermediate thickness. Compare that distribution with the sizes required for your engine.

Common ordering questions

Does the Athena top-end set cover the same seals as oil-seal kit 01-9034?

No. The top-end set and the shaft-seal kit have different inventories. Kit 01-9034 supplies one seal each for the tachometer drive, clutch arm, crankshaft, oil-pump shaft, countershaft and shift shaft. Those six seals are not listed in the Athena top-end set; choose the package that covers the sealing points in your parts list.

Does paper oil filter 15-0002 include the housing seals and supporting hardware?

No. It supplies the paper element; O-ring set 15-0050, spring 15-0055 and washer pack 15-0039 are separate choices for the original-type filter assembly. The washer pack contains five washers.
