1972 Honda CB100K2 · Oil Service Buying guide

Check the plug and its sealing parts together

The plug’s 12mm diameter and 1.5mm pitch define its thread. The linked crush washer has separate dimensions, so confirm the seating arrangement and package contents before completing an order for both pieces.

Parts to consider

Honda CB Magnetic Oil Drain Plug Magnetic Drain Plug12mm diameter and 1.5mm thread pitch, with replacement reference 92800-12000.View part

Related parts: 12 × 18 × 1mm crush washer

Do not transfer another engine’s drain arrangement

This magnetic plug has replacement reference 92800-12000. Use that alongside the actual drain opening when comparing parts. Broad application wording does not establish the number or location of drains on a particular engine, and a repaired opening may need a different thread.

Compare the separate washer dimensions

The linked crush washer measures 12 × 18 × 1mm. Compare those dimensions and the drain seating face with the plug you intend to use. A shared application or nominal hole diameter alone does not establish the complete sealing arrangement.

Ordering questions

Should I order the linked washer with the plug?

Confirm whether a washer is supplied with the plug first. If a separate one is needed, compare the linked 12 × 18 × 1mm washer with the drain’s seating arrangement instead of choosing solely by motorcycle model.

My engine has an oversize drain plug. Can I order this one?

Establish the current thread before buying. This product is specified at 12mm diameter and 1.5mm pitch; those dimensions do not automatically suit an opening that has been enlarged or repaired.

What do the three washer measurements describe?

The related washer has a 12mm inside diameter, 18mm outside diameter and 1mm thickness. Keep all three measurements with the seating-face comparison; the drain thread diameter alone does not describe the complete washer.

Not sure which part you need?

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