There is an underdrive pulley/balancer on the truck I bought. It is a natural silver color, and has SFI 18.1 approved on it, and A508047. I've tried searching that number, and haven't had any luck. Any help?
Here's a couple - nothing great. Some nice surface rust on this thing due to it not being painted! Crank seal is leaking, too. That's one of my first projects. Wanted to throw new belts on it while I was at it. Can't read the numbers on the main belt. A/C has K040332 on it.
