Has anyone ever heard of or seen a crank pulley go bad on an FZJ80?
When you first start my 80 it makes a bit of a growling sound coming from the belts. It seems to go away fairly quickly. When you engage the A/C when it's cold it makes alot of noise. Sounds like a bad idler or compressor. As the RPM goes up or after a few minutes it goes away.
I have replaced the belts with factory belts. Replaced both idler pulleys and lastly replaced the A/C compressor. Really thrilled after I replaced the compressor to find the noise still there. Again, it goes away after a minute or two and only happens after the vehicle sits awhile.
I have noticed when it occurs, I see what looks like movement or a wobble in the crank pulley. My theory.. this week.. is that the rubber in the pulley is getting soft or coming apart. The tension from the belts pulls the pulley slightly off-center when it sits awhile. When it starts, it's wobbling and making noise and then it eventually centers itself after a few minutes? Is this crazy?
Any thoughts? I'm running out of parts to replace....
