Brian, thank you for this video. It was the first time I have asked myself “Why do they call them harmonic balancers!” I have engineering background, and know what a harmonic is, so your explanation made perfect sense. I would never have thought they would separate at the rubber/metal interface such that the timing can be off. Thanks for that lesson. You used a metal screw device inserted into the No 1 spark plug hole, turned it till it made contact with the piston at what is supposed to be TDC, then spun the crank, I guess to find the exact point of TDC, which is important if your system might ever be off. You weren’t all that clear about how you did that, and you didn’t say what that device was or where you got it. I would like to know those things if you don’t mind taking the time. But thanks so much for your informative video. People like you make UA-cam extremely valuable.
I've had my 2011 Mustang v6 about a year now. Sometimes during deceleration there's this little unsettling vibration that comes from the engine followed by random misfires. It's about 50/50 as to whether the engine will throw a code or not. I'm gonna have my mechanic install a new one. I wish I could get a good looking one like these with degrees.
Thus being in sync , without resonance we wouldn't exist. Nice video!!

Thanks for the info about this subject-good advice.
Wow, never thought of that years ago on my Mopars...
new harmonic balancer made my engine run smoother and it downshifts better as well
And your ex-wife likes it.
If the outer ring shifts it won't throw your timing off UNTIL you use the marks to time your engine.
Good point.
Overlooked by lots of mechanics.
Whats their MTBF?
Eleventy seven, give or take a gnats cock.
ain't nobody gonna do all of this. i aint never changed a harmonic balancer and aint never had no problems
Well ain't you special

"Your gas mileage can become just plain awful if your gas mileage is off" No shit Sherlock.
Other to that,I think I learnt something.
