Hey Scotty,
Pretty new viewer, but I watch quite a few of your videos in the last two months. I really enjoyed them.
I have some superficial rust on my crankshaft pulley. How urgent is that that I change that out? Is there a difficult job? Are there other options like putting a coating on it or something?
Thanks
Justin
don't even worry about superficial rust.
Thanks!
You didn't say what kind of vehicle you have, how old it is, or what the mileage is, but typically the only thing you need to worry about with crank pulleys is rubber separation when they get old. Typically the crank pulley is a vibration damper and consists of two sections with rubber bonded between them. The sections can separate when the rubber deteriorates.
Agree probably nothing wrong, just superficial. But it is good practice to look for hairline cracks etc.
Perfect. I’ll keep an eye out for wear in the rubber. Thanks!

A simple way to do that is to mark the two concentric sections of the vibration damper with paint spots next to each other. If they move apart the rubber is bad.
Just did the test, it’s looking good. Thanks for the tips.
Keep an eye on it over time.
