1978 Honda CB750F · Gaskets, seals & hardware Buying guide

Choosing gasket sets and engine oil seals

Choose the package around the openings and shaft locations being serviced. The overhaul gasket assortment, engine oil-seal kits and individual cover seals have different contents; compare them before combining purchases.

Gaskets and seals to consider

Related parts: Eight-piece oil-seal kit · Cam-cover gasket · Tappet-cover O-ring set

What the overhaul assortment supplies

Set 18-0441 includes the head, base, cam-cover, oil-pan, alternator, shift, clutch, oil-pump, tensioner, points-plate and starter-cover gaskets. Its smaller sealing pieces include four exhaust gaskets, a breather-cover O-ring, four sleeve-base O-rings, eight valve-stem seals and eight cylinder-stud packings.

Single-location repairs

Countershaft seal 73-0957 measures 29.8 × 62 × 7 and lists the 1977–78 F. Check whether a selected oil-seal kit already covers that location before adding the individual seal. Cam-cover gasket 18-7003 replaces 12391-300-306 and is also named in overhaul set 18-0441.

Gasket and oil-seal questions

Does the overhaul gasket set also supply engine oil seals and head-nut covers?

Set 18-0441 explicitly excludes engine oil seals and cylinder-head nut covers. Plan those separately when the repair requires them; the valve-stem seals and cylinder-stud packings in the gasket set do not change those exclusions.

Why does one engine oil-seal kit have eight pieces instead of seven?

Kit 01-9018 adds an earlier 25 × 62 × 8 countershaft seal alongside its 29.8 × 62 × 7 option for the 1977–78 K/F. Kit 01-9042 contains the later option with the other six named seals. The extra piece is an alternative application choice, not an additional seal to fit to the same location.

Will the tappet-cover O-ring set fit aftermarket caps?

Set 18-7069 is specifically restricted to OEM-type tappet covers. It supplies eight O-rings replacing 91302-001-020. Identify an aftermarket cap’s own seal requirements instead of choosing this set from the motorcycle’s model year alone.
