1980 Honda CB400TA Hawk Oil Filters & Drain Plugs

For an oil change on the 1980 Hawk, match the paper element to the original filter housing and the drain parts to the crankcase. Keep the drain-plug sealing washer separate from the thin spring-seat washer used in the filter assembly.

1980 Honda CB400TA Hawk · Oil Filters & Drain Plugs Buying guide

Order the filter and the correct washer positions

The filter element, drain plug and drain washer are separate service choices. Confirm the existing thread before selecting the magnetic plug, especially if the crankcase has previously been repaired.

Know which washer you are replacing

The drain washer measures 14 × 20 × 1 mm. The related five-pack is a different item: thin oil-filter spring-seat washers referencing 15414-300-000. Those washers belong with the paper-filter assembly and should not be substituted for the drain-plug seal.

Check the housing hardware during service

The related oil-filter bolt references 15420-413-000 for this twin’s filter arrangement. Inspect the existing bolt and housing before ordering. A damaged crankcase thread needs proper assessment; a new magnetic drain plug should not be used to force a mismatched or repaired thread.

Buying questions

Will the magnetic drain plug fit a repaired crankcase thread?

Only if the repaired fitting still matches M14 × 1.5. Measure or identify the installed thread first; an oversized repair plug changes the part required regardless of the motorcycle’s original specification.

How many filter spring-seat washers does one Hawk use?

The original filter assembly uses one spring-seat washer. The linked pack contains five washers, leaving spares when renewing that one position; it does not supply five complete oil-filter service kits.

Can I replace a damaged oil-filter bolt separately?

Yes. The linked bolt is a separate replacement for the CB400T filter housing. Compare the fitted bolt and inspect the housing threads first; replacing the bolt alone does not repair a damaged threaded fitting.

Not sure which part you need?

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