1975 Honda CB750K · Electrical Tools Buying guide

Match the tool to the plug or switch retaining nut

The plug wrench is selected by its 18mm working hex, while the switch tool is listed for the CB750K retaining nut. Neither listing establishes a general electrical testing or wiring repair application.

Choose the plug wrench by its working size

The tuck-away wrench is listed as 18mm, with a thin-wall design and 160mm overall length. Confirm the hex size on the plug fitted to your engine. These are tool dimensions, not a replacement spark plug specification or proof of compatibility with every plug someone may have installed.

Check the switch before ordering its nut tool

The retaining nut tool lists the 1969–76 CB750K ignition switch application. If the switch or mounting arrangement has been changed, compare the nut with the product. The tool assists the specified nut service; it does not supply a replacement switch, electrical contacts or new wiring.

Common questions

Does the spark plug wrench include spark plugs?

The listing is for an 18mm spark plug wrench with a tuck-away handle. It is workshop equipment, not a plug set. Choose any replacement plugs separately using the correct specification for the engine.

Does the ignition switch tool replace the switch?

No. The product is a tool for loosening and tightening the retaining nut on the stated switch application. Diagnose the switch separately and choose replacement electrical components independently if the repair requires them.

Can either tool diagnose an electrical fault?

Their listed functions are plug removal and installation, and ignition switch nut service. They are not electrical test instruments. Use the appropriate diagnostic procedure rather than assuming the electrical-tools category implies testing capability.

Not sure which part you need?

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