If you are doing other engine work & have it off or readily acessable it might be a good idea but if it,s just a routeen inspection I wouldn,t.

The rubber deteriorates with age and exposure to oil. The problem is that no one makes them, good used ones are darned hard to find, and getting one rebuilt isn't cheap. http://www.damperdoctor.com/Merchan...&Store_Code=DD&Category_Code=HAR Most are running their old damper on stock engines. For a performance engine, a new or rebuilt damper is needed. One option there is to take a fluid damper for a SBC and adapt drive pulleys to it.

I got the truck for $250 and I plan on using it to haul firewood and other nasty stuff and I figure I will not have to worry about scratching the paint. I need to remove the dampner, since I plan on changing the timing set, since the truck has 113,000 miles on it and I was wondering if I need to replace dampner. If the cracked rubber is more a cosmetic thing rather than a performance/safety concern than I will just leave it be. There, I aired my dirty laundry, please be kind. At least it is an American vehicle!

For what its worth I believe I have discovered the truck is actually a 1978 even though the PO and Owners manual says that its a 1977. The grill and hood match a 1978, not the 1977. Same type of thing happened when I picked up my 1954 GMC 1/2-ton 3 years ago. The PO told me it was a 53 GMC 3/4-ton and the title had it listed as a 53 1/2-ton. The one piece windshield, square parking lights, and distinct dash layout told me different.
