Had an ISX in yesterday. Owner said it had an engine knock. It did when you started it and shut it off. Not AS much when running. Owner had made a number of changes. We got lucky. Spotted a tiny crack in balancer. When we pulled it the whole center under the pulley was broken in a circle. If the owner had made another trip the damage would have been extensive, balancer on its own isn't free. Check them but really think about changing at manufacturer recommended interval. Art Pfluger

He had them for everything including driveshafts. Dunno as I'd trust any of them except for tires. I run them all the way around and do get good tire wear.

ROSE PFLUGER ROAD WARRIORS TRANSPORTATION INC MORRISTOWN, AZ 613 Posts, 4 +, 3 -	ROSE PFLUGER ROAD WARRIORS TRANSPORTATION INC - MORRISTOWN, AZ Balancers are more important and ignored than you think. I personally have an emodel cat with a 2 peice crankshaft. I rebuilt 30,000 prior to this and spent $16,000 in parts alone. I however upped horsepower in excess of 650 so what was the cause of breakage. Analysis says harmonics, horsepower, and cásting flaws in e models. We are seeing more balancer trouble and that is why we need to heed warnings to replace. As far as centramatics, don't know. Run them on wheels. They will only solve 4 oz of balance, but if your close they are great. We find that the cost of a balancer is a waste. I however bought a mercury balancer for my son's 6 NZ that he stole from me, it took that small amount out. Value??? Depends on are you driving it or a driver, not finding worth past personal value. I can relate to the struggle between maintenance and extravagance, but if that balancer gets loose it'll cost you. The cost difference, at least for me in my shop vs on the road is crazy.

ORIN SR. SCHIMMEL SCHIMMEL TRUCKING Pickett, WI 2 Posts, 0 +, 0 -	ORIN SR. SCHIMMEL SCHIMMEL TRUCKING - Pickett, WI balancers are overlooked a lot. In the 80s Ihad a KT 525 Cummins that had a bad balancer. It broke the drive shaft of the waterpump 3 times, worbled out the keyway of the AC pump before I found out what was wrong. this was very costly as anyone who knows about the cost of these engines. Now I have a Pete with a 2WS Cat 3406E. I made a small bracket and bolted it to the head so I could get up easier to wash my windshields. It required 5/16 bolts, used grade 5. 2 days later went to use this bracket and found it laying on the starter with the bolts broke off. Replaced the bolts with grade 8 and another one broke off. I relized the balancer was bad at that time, replaced the balancer and the problem is solved
