1974 Honda CB350F1 Engine Gaskets & Seals

Choose sealing parts for the joint or shaft being repaired on your 1974 CB350F1. An overhaul gasket set, a shared engine oil-seal assortment and an individual shift-shaft seal serve different jobs; their package names do not make them interchangeable.

1974 Honda CB350F1 · Engine Gaskets & Seals Buying guide

Match the leak to the sealing part

Plan gasket and oil-seal orders separately. Confirm the cover or shaft position, compare dimensions where supplied and check kit contents against the components you will actually remove.

Gaskets and oil seals cover different work

The Athena set is an engine overhaul gasket set for the stated 1973–74 CB350F application. The nine-piece oil-seal kit is a separate assortment for CB350F and CB400F. Its contents include a clutch-cover seal specifically identified for CB400F, so nine pieces does not mean nine identical F1 requirements.

Avoid replacing more than the repair needs

The individual shift-shaft seal provides a dimensioned choice for that location. For a wider overhaul, inventory the old sealing pieces and the purchased kit before assembly. Do not assume that a product described broadly as a cylinder-head gasket represents the large main head joint.

Ordering questions

Does the gasket set replace the oil-seal kit?

They are separate purchases with different functions. Use the overhaul gasket set for the relevant engine joints and verify which radial oil seals your repair needs before adding a seal assortment.

Will every piece in the nine-piece kit be used on my F1?

Not necessarily. The shared kit explicitly includes a right clutch-cover seal marked for CB400F. Match the contents to the CB350F1 assembly rather than forcing every supplied piece into the rebuild.

What should I check for a shift-shaft seal order?

Match the shaft location and the specified 14 × 28 × 7 mm dimensions. The replacement reference is 91206-286-013; compare it with the fitted seal if the engine has been changed.

Not sure which part you need?

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