1971 Honda CB500K Oil Filters, Drain Plugs & Oil-System Parts

Check the oil-filter arrangement on your 1971 CB500K before filling the cart. A factory-style paper element and the chrome spin-on conversion use different hardware. Compare drain-plug thread details, then add only the separate housing seals or parts your existing setup needs.

1971 Honda CB500K · Oil filters & drain parts Buying guide

Identify the filter housing before ordering

A paper element serves the original-type assembly, while the chrome spin-on product replaces that housing, its bolt and element. Magnetic drain plugs are another choice entirely; confirm the plug thread against the installed engine.

Parts to consider

Honda CB Oil Filter ~ Replaces 15410-426-010 Original-type paper filter elementThe stock-type paper element lists references 15410-426-010 and 15410-422-004. Housing O-rings, springs and washers are available separately.View part Honda CB Magnetic Oil Drain Plug 12 mm magnetic drain plugListed with 12 mm diameter and M1.5 thread, against reference 92800-12000. Match the existing drain opening; magnetism does not change thread compatibility.View part Honda CB Chrome Spin On Oil Filter (Cover + Oil Filter) Chrome spin-on filter conversionThe listing describes replacing the original housing, filter bolt and paper element. Read its installation notes before selecting it as an alternative filter arrangement.View part

Related parts: Factory-type filter-housing O-rings · Original-type oil-filter spring

Keep the two filter arrangements distinct

Order the paper element for the factory-type assembly, or review the spin-on conversion as a different arrangement. Do not assume a replacement paper element belongs inside the conversion. Its listing also contains an installation note about fitting the threaded bung before the filter.

Use the plug specification, not its finish

The magnetic plug is described as 12 mm diameter with M1.5 thread. Compare those details with the installed engine, especially after repairs or a swap. A drain-plug choice should not be based only on the model selector or a similar-looking bolt head.

Questions about oil filters & drain parts

Are seals and hardware included with the paper element?

The paper-filter description explicitly says new O-rings, springs and washers are available separately. Check the condition and presence of the existing housing parts, then add the specific replacements needed rather than assuming the element is a complete service kit.

Which filter should I choose for the arrangement already fitted?

Choose the paper element for the original filter housing. The chrome spin-on product is a conversion replacing that housing, its bolt and the paper element. Identify the installed arrangement before buying original housing parts or planning the conversion.

What thread should I match when replacing the drain plug?

The magnetic plug is M12 x 1.5 and references Honda 92800-12000. Compare that specification with the existing drain fitting before ordering, especially if the engine or drain threads have been changed.
