1973 Honda CB175K7 · Oil Drain Plug Buying guide

Check the drain opening and the space around it

The 6061 aluminum plug includes an O-ring and a steel-debris magnet. Its outside diameter, case projection and socket size let you assess both installed clearance and access for later oil changes.

Parts to consider

Honda CB Joker Machine Magnetic Oil Drain Plug ~ Replaces 90013-312-000 Joker Machine magnetic drain plug6061 aluminum plug with O-ring, M33.7 × 1.5 mm thread and a rare-earth magnet for steel debris.View part

Compare three dimensions, not just the thread

Compare the case opening with the M33.7 × 1.5 mm thread, then allow for the plug’s 45 mm outside diameter and 19 mm projection. If an exhaust runs close to the drain opening, check access for removal as well as clearance with the plug installed.

Choose the magnetic plug for steel-debris collection

The rare-earth magnet collects steel debris from the sump. It does not collect every kind of wear material, so retain the engine’s specified oil-service routine. Use the appropriate service information for the sealing arrangement, installation procedure and tightening specification.

Buying questions

Will the plug clear a nonstandard exhaust?

Compare the exhaust position with the plug’s 45 mm outside diameter and 19 mm projection from the case. Leave working access for a 19 mm socket; thread compatibility alone does not settle exhaust clearance.

Should I reuse the seal from my existing drain plug?

This replacement comes with an O-ring. Compare that sealing arrangement with the fitted case before ordering, especially if a previous repair changed the plug. Do not assume a washer from a different plug is the required seal.

What benefit should I expect from choosing the magnetic version?

Its rare-earth magnet is intended to collect steel debris that can be inspected during oil changes. Choose it for that function without treating it as a replacement for the engine’s normal oil-service requirements.
