1985 Honda CB450SC Nighthawk Oil Service Purchase Checks

Inspect the existing service pieces before ordering for your 1985 CB450SC Nighthawk. A damaged housing bolt, worn filter washer or suspect warning switch calls for its own comparison. For a magnetic drain-plug change, establish the thread and plan the sealing washer separately from the photograph.

1985 Honda CB450SC Nighthawk · Oil Service Buying guide

Inspect the filter hardware and warning-switch match

The paper element is listed by three Honda references. The magnetic plug uses M14 × 1.5 threads, and the genuine Honda switch needs a matching reference, terminal and sealing arrangement. Individual filter washers, the drain washer and the separate housing bolt provide focused replacement choices.

Parts to consider

Decide which filter hardware needs renewal

The 15414-300-000 filter washer is offered individually or in a five-pack. Inspect the removed washer for cupping, cracks, deep scoring or flattening rather than adding replacements by habit. The housing bolt replaces 15420-413-000; its written listing does not specify included extra hardware, so confirm what arrives before the job.

Treat the drain washer as a planned service item

The separate washer measures 14 mm inside, 20 mm outside and 1 mm thick, with one used at the engine drain plug. Renew it whenever the plug is removed. Check the sealing requirement and supply with the magnetic plug rather than counting the loose washer in its photo as a guaranteed inclusion.

Oil Service purchase questions

When does the filter washer need replacing rather than reuse?

Inspect it after removal for cupping, cracks, deep scoring or flattening. Those conditions justify replacement with the matching 15414-300-000 washer. Keep the Honda-specified filter-bolt position and tightening procedure; the washer’s appearance does not establish a different location or repair method.

What protection should I expect when choosing the magnetic drain plug?

Its magnet captures ferrous steel particles but does not collect aluminum. Verify the M14 × 1.5 thread and Honda 92800-14000 match before choosing the plug, and confirm the sealing-washer supply separately from the photograph.

What should I confirm if the filter housing bolt is damaged?

Compare the removed bolt with Honda reference 15420-413-000 and confirm the supplied contents before ordering. The bolt is offered as a separate product, but the written description does not identify accompanying washers or other hardware needed for your particular repair.
