1973 Honda CB500K Paper Filters and Housing Hardware

Look at the filter hardware fitted to your 1973 Honda CB500K before choosing service parts. A paper element and housing bolt suit the original-style arrangement. The chrome spin-on product replaces that arrangement, while drain-plug choice depends on the stated thread and reference.

1973 Honda CB500K · Oil Filters and Housing Buying guide

Identify the housing before choosing its service parts

The paper element, original-housing bolt, O-ring set and spring are separate offerings. The magnetic plug specifies M12 × 1.5, and the chrome spin-on conversion replaces the housing, filter bolt and paper element rather than renewing them.

Parts to consider

Honda CB Oil Filter ~ Replaces 15410-426-010 Single paper oil-filter elementOne stock-type paper element is included, cross-referenced to 15410-426-010 and 15410-422-004. It does not include the separate housing O-rings, spring or washer.View part Honda CB Oil Filter Bolt ~ Replaces 15420-300-020 Bolt for the original-style filter housingThe replacement bolt is listed against 15420-300-020 for the stock filter and housing, including CB500K applications. Check the retained housing arrangement before choosing it for the repair.View part Honda CB Magnetic Oil Drain Plug M12 × 1.5 magnetic drain plugThe stated thread is M12 × 1.5, with reference 92800-12000. The magnet collects ferrous steel particles; it is not described as capturing aluminum debris or replacing the oil filter.View part

Account for the parts around the paper element

The paper filter supplies the element alone. The housing spring’s current contents statement supplies one replacement spring, and the O-ring set serves the factory-style housing separately. Check the washer and bolt too, using the retained assembly to decide which additional service parts are needed.

A conversion replaces the original arrangement

The chrome spin-on description names the stock housing, filter bolt and paper element as the parts it replaces. Choose that conversion intentionally instead of combining it with an assumed replacement element for the original housing. Refer to its current product information for the conversion-specific assembly requirements.

Buying questions answered

What specification should I compare before ordering the magnetic drain plug?

The plug uses an M12 x 1.5 thread and replaces Honda 92800-12000. Compare that specification with the fitted drain plug, especially after an engine change or drain-thread repair; a shared model application cannot identify altered threads.

When should I include the replacement stock oil-filter bolt in my order?

The bolt references 15420-300-020 and is for the original-style paper element and housing. Compare the fitted bolt and housing before replacing it. The spin-on conversion replaces those components, so identify the filter arrangement first.

Is a washer explicitly included with the magnetic plug?

The featured photo shows a washer beside the plug, but the current description does not specify that supplied item. Confirm the required washer contents separately instead of deriving a package promise from the picture.
