1968 Honda CB350K0 Seals & Engine Hardware

Oil sealing and clutch-release hardware meet in this small selection, but they need separate diagnosis. For the 1968 CB350K0, compare the gear-change shaft seal dimensions and identify the clutch ball retainer before buying parts for the opened engine.

1968 Honda CB350K0 · Seals & Engine Hardware Buying guide

Identify the leaking seal or worn mechanism

A correctly sized shaft seal addresses a specific opening in the crankcase. The clutch ball retainer belongs to the operating mechanism, so check its condition separately while planning the work.

Measure before replacing a seal

The shaft seal is specified at 14 mm inside diameter, 28 mm outside diameter and 7 mm thickness. Compare these with the removed part and the undamaged housing. Engine history matters if cases or shafts have been replaced.

Inspect the clutch operating pieces

The ball retainer is a separate clutch component, rather than a general cover-fastener kit. Inspect the surrounding operating parts when assessing wear, and use the CB350 workshop manual for assembly and adjustment instead of treating a new retainer as a complete clutch rebuild.

Common buying questions

Will this seal fit every oil leak on the engine?

No. It is the shift shaft seal, specified as 14 × 28 × 7 mm. Identify the leak location first; a cover joint or another shaft requires its own sealing part.

What should I check before choosing a clutch ball retainer?

Compare the retainer and its mating operating surfaces with the fitted mechanism, using reference 22860-286-000. Inspect the complete clutch control before attributing a stiff or uneven action to this component alone.

What should I compare on a replacement engine?

Check the actual shaft, seal recess and clutch mechanism against the dimensions and references shown here. The motorcycle’s registration year alone cannot identify components fitted during an earlier engine swap.

Not sure which part you need?

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