1970 Honda CB350K2 · Gaskets, Seals & Retainers Buying guide

Identify the leak or mechanism before choosing parts

A wet engine case and a worn clutch mechanism call for different service parts. Trace the fault and decide what must come apart before choosing an overhaul gasket set, a targeted seal or a retainer.

Choose the gasket set by repair scope

The Athena set explicitly covers the 1970–72 CB350K. Use it for a planned engine overhaul rather than assuming it solves every fluid leak. Check the individual joints in your job list, including any separate oil seal that will be disturbed.

Keep the retainer repair separate

The clutch ball retainer replaces reference 22860-286-000 and has an explicit CB350K application. Compare the removed retainer and inspect the surrounding operating mechanism before ordering. A gasket overhaul is not evidence that this mechanical component also needs replacement.

Common buying questions

When is an overhaul gasket set the useful choice?

Choose the Athena set for a repair that opens the relevant engine joints. For an isolated leak, first identify the failed seal or gasket and confirm whether a targeted replacement covers the work.

What size is the shift-shaft seal?

The replacement is 14 × 28 × 7 mm and references Honda 91206-286-013. Check the shaft, housing and source of leakage before ordering, especially if the engine has been changed.

Is the clutch ball retainer part of the gasket set?

The clutch ball retainer is a separate operating-mechanism component, reference 22860-286-000. Order it for an identified retainer problem rather than adding it automatically to a gasket repair.
