while they can fail due to dry rot(small cracks),
the 2 biggest reasons for failure are oil leaks breaking
down the rubber, and stupid people smacking them on
with a hammer......this is true for ANY engine, not just
the 6.5 as SOME people would lead you to believe.

I had one trash out at 85,000 miles..It caused a massive ticking sound, like bearings in a compressor or alternator going. I couldnt figure it out....till I read bout it somewheres. Mine trashed out early probabaly because our PTO setups run off that pulley, and add alot of force on the crank pulley. When I undid the PTO belts the pulley pretty much seperated...It was like 80 bucks for a new one from GM..I have heard alot of these failing myself......If I didnt have the PTO belts holding the pulley on...she would have gone right through the radiator.

I had my crankshaft break at 112,000 miles, and the probable cause was the balancer. The rubber had moved and squeezed out between the two pieces which may have produced enough vibration to cause the crank to snap, some others have had the same issue and it seems that at about 100,000 miles may be the life of the rubber that goes bad. Check yours all around on both the front and back, if its comming out I would replace it.

With the key ON, the controls do nothing. I get...

He is road tripping by himself and luckily has a cousin following him so has separate transportation. We confirmed it was gas.
So...drain the tank put several gallons of diesel in it and then flush the lines until diesel is coming out.
Then new fuel filter.
Then try to start?
This is for 99 dually with 6.5.
So, now that truck is running again after my teen used gas instead of diesel...sigh.
I actually had the feed the beast upgraded FFM from leroy diesel sitting in the truck.
History, I've got rid of most leaks on the truck and figured out I was still leaking...
Hi, a newbie here. However, I've posted stuff on many a forum about other stuff in the past and people are always super helpful, so thanks in advance.
