Couple of things. So first off the HB has to go on in a specific orientation based on the balancing holes drilled into it so it doesnt off balance the rotating assembly. Secondly you never heated up the balancer. When you install it, you’re supposed to throw it into an oven between 105°-165°. That will cause the opening to swell and you’ll be able to slide it on. MAKE SURE you keep a CONSTANT eye on the HB. Some manufacturers use cheap materials and the rubber could become structurally unsound and start to melt and burn. Heat it to just before it starts to smoke and keep it at that temperature for about 10 minutes. Then remove it and install.
@@737mechanicok. What do I know? I only own the number one automotive shop in North Carolina. Look. Just because it’s not in the manual does not mean there have not been updates or TSB’s on it that is not available to the general public. What I’m telling you is the proper and correct way you’re supposed to do it.
@@StardustAutomotive You stated that you are supposed to heat it and that is NOT the case. Will it help? maybe but I never heat them and with the proper tools they go on just as they are supposed to. To tell someone you are suppose to put them in the oven and heat them right until it starts smoking all you are doing is setting someone up to destroy their harmonic balancer by melting the rubber. No manual tells you to do that.
Ok Mr: Know it all. I’m not getting into a who’s dick is bigger contest. The fact I have been given awards through several ASE recognized organizations, several state recognitions, own the number one shop in the entire state and over 33 years of professional experience means absolutely nothing compared to your almighty UA-cam wisdom and knowledge. 🤣🤣🤣. Have a nice day there chief.
If a harmonic balancer has holes drilled into one side at the factory, would this suggest the engine is externally balanced? And would this mean that harmonic balancers are not interchangeable? No and No Technically, the word "balancer" is accurate by the dictionary definition but misleading by the industrial definition of balancer. The automotive harmonic balancer is more accurately described as a, inertially induced displacement damper. (an orbiting shock absorber) "Balancing" in terms of rotor body is the axis alignment of a center of geometry with a center of mass so "balancing" to whatever standard is RPM specific ( and can be affected by thermal growth) and a process of alignment, geometric considerations and mass adjustment (addition or removal of weight) and in some applications the additional considerations of fluid dynamics external to the machine. In terms of that- the harmonic balancer simply takes various vibrations induced from rods, engine geometry, timing, displacement etc. and "blends" ( harmonizes) then with whatever rubber or fluid method it uses to "smooth" things out. Given what they do and how they work, as long as you have an ISO interference fit, they will work adequately because in spite of all the articles written, its virtually impossible to balance and maintain an ICE to any recognized balancing standard. Even if you achieve it statically, it is unlikely to hold dynamically as RPM increases due to the operating properties of cranks and rods along with combustion energy. The best that can be achieved is precision machining for alignment and fit with very careful gram weighing and truing to equalize the weight of the parts. (which does make a significant difference when done properly)
given the new painted stuff, most likely the infamous AFM DOD collapsed lifter destroying the cam shaft. hopefully he got in on the class action lawsuit at the time he made this video.
7:45....OOOF using a 12 point for a hex bolt with 240ft pounds of pressure (factory). then unbalancing the balancer by sliding stuff thru it's balancing arms. you should have just bought a regular pulley instead of kidding you're self you're not going to destroy that engine.
Them kits are junk the tool to remove the pulley works fine after you make your own bolts the pins they supply don’t work they’re not long enough I used threaded bolts and rapped them with tape so I didn’t mess up the threads inside the crank I ha to make two different length bolts so the puller had something to press against and the installer is completely junk none of the supplied bolts fit the crank so just use the original bolt to put your pulley on
Hope you used the old bolt to put that on think its tty you stretched it with the impact

The maintenance manual does not say to heat the harmonic balancer up.

Great video...may i ask how far does the HB goes on?
They put it on the bottom to get a good laugh at it. I have done the same
Why were you changing the HB? What was the symptom?
