which balancer for my engine C15?

Damper? Vibratek, made in America - I believe that it's the same thing as PDI, and Pitts Power they just rebrand it. Was told by Haney CAT OEM uses Chinese silicone and is of poor quality - will not last as long.

 

I agree with rollin coal vibratec is the only way to go, also use the mercury crank balancer that PP sells

 

i put a vibratec damper on my 6nz seam to run alittle smoother i took the stock damper and cut it in half had over a million miles on it the silicone was still fluid good or bad i dont know but did run smoother with the vibratec

 

The damper does nothing till over 1500 RPM, many power units that run at 1800 do not have a damper so you can feel it?
This is anouther sales pitch thread, on Cat warrenty you check the damper if it is not bent, visually, or when you take it off and bounce on the tire it rattles it is good.
Just a thought!

 

I don't get how a damper does nothing under 1,500 rpms? At a million miles it was just one of those things I figured it was time to replace. Not trying to be a sales pitch.

 

They're supposed to be replaced at 500,000.

I run a Vibratech from PP. I called Vibratech and was told just to buy it form one of their distributors and they told me to call PP.

 

Power units that run 1800 or more don't have a damper? Then I wonder why there was one on a 4L inline 6 in a Jeep Cherokee I had. Check the parts schematics.... yep, the 4L inline 6 had a crankshaft damper. So did the 2.8L inline 4 cylinder diesel in a 2006 Jeep Liberty I owned. And your concept on "testing" to see if a damper is good. You must be just trying to pull our lariats here. Do you have any real idea of what they are made of and how it is the components inside of it work? If it "rattles", it is staying off and getting replaced on my engine.

I can't speak to every engine out there, but I do know for fact that Detroit, in the owners manual, recommends replacing the crankshaft damper at 500,000 miles.

 

I have every Detroit manual there is and it does say to replace the damper at every major overhaul and if there is a crank failure. I did engine repairs and never replaced a damper except when a major overhaul kit was bought.
I did maybe 2 of those overhauls the benefit of doing those was the warrenty available. Testing the damper that is done, Cummins has the same style kits available and it includes a damper.
We had a few dampers, with the rubber rings fail while the truck was on the road, many were Cats, we told them to keep the RPM below 1600 and bring it in when he got back, The Dampers with the rubber had timming marks and you did have to look at the marks being sure they lined up.
Detroit manuals have the damper in section 1.36. they are just covering their butt. If you replaced everything, in an overhaul, you might as well buy a new engine, then there could be a transmission problem or a rear gear problem, Might as well buy a new truck.
Reality is that trucker do not make enough money to replace every part, you replace what is needed. Breaking a crankshaft, that is very rare, in a modern engine. I have removed a lot of dampers, to inspect them when there is an abnormal noise, I very much doubt I have replaced, a dozen dampers for a failure, in a damper that was not damaged in an accident.
You can change a lot of things to extend the engines life, the oil is the one thing that does work.
Every engine has a different arrangement, and characteristics, if the engine can rev higher than 1800, it may need a damper, some arrangements that rev higher do not. Some engines have extreme vibrations at certain revs the 1710 Cummins come to mind.
Just a thought!

 

JP3 do you even know what a damper is supposed to do? The way you talk you make it sound as if it's job is to balance the engine. Which by the way is not it's function.
