1985 Honda CB450SC Nighthawk Fuel Cap and Petcock Repair Choices

Tank hardware service on a 1985 Honda CB450SC Nighthawk has two distinct component checks. The locking cap must match the hinge, latch and filler-neck sealing surface. The petcock repair kit lists soft parts for the compatible 1985–86 valve, whose body and sealing faces need inspection before committing to a rebuild.

1985 Honda CB450SC Nighthawk · Tank Cap & Petcock Service Buying guide

Match the cap to the tank and the repair pieces to a sound valve body

The cap replaces 17620-460-067 and includes its gasket and two keys. The petcock kit supplies one diaphragm, one spring and two O-rings for one compatible valve. Those package contents help count the order, while the tank interface and valve-body condition determine whether each purchase suits the repair.

Inspect the valve before treating the soft-parts package as the repair choice

The petcock listing identifies corrosion or damage at the valve body and sealing faces as inspection concerns and calls for clean fuel passages. It specifically warns that the kit cannot repair a badly pitted or cracked body. Let those findings guide the purchase rather than relying on the model entry alone.

Compare the tank opening and test the supplied cap keys

The cap guidance names the hinge, latch and filler-neck sealing surface as matching points. It also calls for both supplied keys to operate the lock, a secure latch, an even gasket seal and venting as designed. The listing makes no existing-key match or custom-tank adaptation promise.

Parts ordering FAQs

What valve condition should be established before ordering the petcock kit?

Check the body and sealing faces for corrosion or damage and assess the fuel passages. The listing says a badly pitted or cracked body cannot be repaired by this soft-parts kit. Confirm that condition before choosing its diaphragm, spring and two O-rings.

Which cap interfaces should be compared if the tank has been changed?

Match 17620-460-067 and compare the hinge, latch and filler-neck sealing surface with the tank fitted. The model application does not document every replacement tank opening. Those physical interfaces need confirmation before the cap’s gasket and supplied keys become useful package details.

What should the cap order account for regarding keys and sealing checks?

The cap includes its gasket and two keys; no compatibility with an existing key is stated. The listing asks for both keys to operate the lock, the latch to close securely and the gasket to seal evenly, with tank venting confirmed as designed.
