I noticed a slight wobble of the crankshaft pulley while the engine was running. Looking closer I noticed the neoprene on the damper was cracked and not spaced evenly around the circumference. Didn't look like there was any recent movement, but don't think this is proper. I tried doing a search for this subject and came up empty. I seem to remember this topic discussed on here before and believe there was a place out in the NW USA that rebuilds dampers. Would appreciate thoughts and comments on this.

Jim, it has been discussed. Seems like not that long ago. If memory serves a dampener from a Detroit diesel of some sort might work?

Here's one link; https://www.allischalmers.com/FORUM/7080-looking-for-advice_topic204806_post1753618.html?KW=dampener#1753618" rel="nofollow - https://www.allischalmers.com/FORUM/7080-looking-for-advice_topic204806_post1753618.html?KW=dampener#1753618

Mike's link discusses the fluid dampeners used on the higher horsepower engines. I'm not sure if the guy in Oregon?? is still rebuilding the rubber dampeners. Dale manufacturing, I think.

Right Jim is referring to the rubber in the crank pulley

Yes, and I had it done by Dale Mfg in Salem, Oregon. Address is 3425 Fairhaven Ave NE zip 97301. Email: langsatherdavid@gmail.com It is my understanding that he has officially retired now, but check that out for yourself. A & I products has new ones with p/n A-74037126.

Purely out of curiosity I had a google search, and turned up a firm in California -

http://damperdoctor.com/" rel="nofollow - http://damperdoctor.com/ - which lists custom rebuilding of harmonic balancers, including for heavy equipment. May be worth asking them, just in case they can help?
