Troubleshooting & FAQ
How do I know if this washer fits my specific engine?
First, check the "Engine & Model Compatibility" table in this listing. If your model is there, it's a confirmed fit. For absolute certainty, compare part number 90201-12565-00 with the part number specified in your engine's service manual or parts diagram.
What are the signs of a worn or failing plate washer?
A failing washer can lead to loose connections, vibrations, or fluid leaks if it's part of a sealed assembly. During routine maintenance, inspect the original washer for signs of corrosion, cracking, or deformation.
When should plate washers be replaced?
It is best practice to replace washers any time the fastener or component they secure is removed. They are often considered single-use parts that compress or deform to create a seal or apply tension, and reusing them can compromise a repair.
