1981 Honda CB750K · Oil Filters, Drain Plugs, Oil Pump & Gauges Buying guide

Check the filter housing as well as the element

The paper element listing offers separate O-rings, springs and washers. Inspect what is already present in the housing, then compare the drain plug’s own specification and washer rather than combining unrelated hardware.

Parts to consider

The product description identifies housing O-rings, springs and washers as separate purchases.View part Honda CB1100/CB1000/CB900/CB750 Oil Filter O-Rings Factory-housing O-ring setThe listing specifies the factory-type filter housing and pairs this O-ring set with the featured paper filter.

Build the filter order from the installed housing

The featured filter is an element, rather than a complete housing assembly. Its description directs you to separate O-rings, springs and washers. Identify damaged or missing pieces before ordering, and use the stock-housing bolt listing only after confirming that housing arrangement is still installed.

Keep drain parts on their own checklist

The magnetic plug and its washer have their own dimensions, separate from filter housing parts. The drain washer listing gives 14mm by 20mm by 1mm. Compare the current plug and seating arrangement, and review product availability before planning the service around a particular replacement.

Common questions

Does changing the paper filter also clean the oil pickup strainer?

No. Honda treats the oil strainer as a separate service item accessed through the oil pan. Replacing the housing’s paper element does not clean that screen; plan strainer work separately if inspection or diagnosis calls for it.

Is the engine-assembly oil capacity the amount for a routine oil change?

Honda gives different quantities for an oil change and engine assembly. Use the change instructions and final level check for routine service, rather than pouring in the larger assembly quantity.

Can I let the engine run if the oil-pressure light stays on after service?

No. Honda instructs you to stop the engine immediately and find the cause if the pressure warning remains on. Do not assume a new filter or a replacement pressure switch has resolved the problem.

Not sure which part you need?
