Frequently Asked Questions
What is included with starter-motor cover 31280-300-000?
One USA-made as-cast aluminum finned cover replacing Honda OEM 31280-300-000 is included. The gasket, O-ring and mounting hardware are not included.
Does the as-cast starter cover need finishing before installation?
The cover can be used with its natural cast appearance or sandblasted, painted or powder coated. Deburr and clean it thoroughly so abrasive or finishing residue cannot enter the engine.
What should be checked during starter-cover installation?
Use the correct gasket or seal on flat, clean mating surfaces and compare bolt lengths with the originals. Tighten the fasteners evenly to Honda specifications without forcing a warped cover.
