1968 Honda CB350K0 Oil Filter & Drain Parts

The CB350K0 has a centrifugal oil filter, so its filter hardware is different from a disposable paper element. Separate work on the filter rotor from work at the drain opening, then compare the washer or plug with the assembly being serviced.

1968 Honda CB350K0 · Oil Filter & Drain Parts Buying guide

Choose hardware for the correct oil-service point

The angled rotor washer and magnetic drain plug serve different locations. Match the original hardware, and check the larger aftermarket plug’s clearance if nearby exhaust or engine parts have changed.

Parts to consider

Allow space around the drain plug

The Joker Machine plug includes an O-ring and uses a 19 mm socket. Its body is 45 mm outside diameter and projects 19 mm off the case. Compare those dimensions with the actual motorcycle, especially around non-original exhaust routing.

Retain the centrifugal-filter service plan

The angled washer belongs to the oil-filter rotor assembly. A magnetic drain plug catches steel debris but does not replace centrifugal-filter maintenance. Follow the Honda manual for the filter’s cleaning, inspection and reassembly requirements, keeping the two jobs distinct.

Common buying questions

Is this a replaceable paper oil filter?

No. These parts support the CB350K0’s centrifugal-filter and drain assemblies. Identify the cover, rotor hardware or drain component you need before ordering; a paper element is a different type of filtration part.

Does the magnetic drain plug include its seal?

An O-ring is included. Before ordering, verify the M33.7 × 1.5 mm thread and room for the 45 mm outside diameter and 19 mm projection from the case.

What should I compare before ordering the rotor washer?

Compare the removed rotor hardware with the replacement’s angled form and stated 16 mm size. Use reference 90481-292-000 to identify this product, and follow Honda’s service information for the assembly arrangement.

Not sure which part you need?

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