1970 Honda CB175K4 · Oil Drain Plug Buying guide

Check the case opening and the space below it

The drain plug has to suit both the threaded opening and its surroundings. Compare the complete assembly, including the O-ring and tool access, especially where an engine or nearby hardware has been replaced.

Parts to consider

Honda CB Joker Machine Magnetic Oil Drain Plug ~ Replaces 90013-312-000 Magnetic Oil Drain PlugJoker Machine aluminum plug with an O-ring and rare-earth magnet. Check its M33.7 × 1.5 thread and 45 mm outside diameter.View part

Separate tool size from installation guidance

A 19 mm socket fits the featured plug’s tool interface. The body measures 45 mm across and projects 19 mm from the case, so access and clearance need separate checks. Use the applicable service instructions for the sealing and tightening procedure.

Know what the magnet contributes

The plug’s rare-earth magnet collects steel debris; it is not a substitute for investigating unusual material during service. The O-ring is supplied with the plug. Continue to use the correct oil-service schedule rather than extending intervals because a magnetic plug is fitted.

Oil Drain Plug questions

Which measurements should I compare before buying?

Check the M33.7 × 1.5 thread, the sealing arrangement, the 45 mm outside diameter and the 19 mm projection from the case. These checks matter on modified or replacement cases.

Is a separate O-ring needed for the initial installation?

The featured plug includes an O-ring. Inspect the supplied sealing arrangement against the case and use the appropriate service procedure; do not assume the old plug’s seal can be transferred.

Will the plug clear an added guard or nearby bracket?

Allow for the 45 mm outside diameter and 19 mm projection from the case, plus access for a 19 mm socket. Compare those spaces with any guard or bracket fitted to your motorcycle.
