Yes they can squeal when the rubber to metal bond has been broken, the metal ring then moves over the rubber making a loud squeal. If that is the case it can sound much like a pending bearing failure on the alternator or water pump. This also means that your balancer can potentially fly apart at any moment and cause severe damage to the radiator or crankshaft sensor (if equipped). Also when the metal belt pulley does eventually slip off it will no longer be driving all the pulleys.
Harmonic balancers are located on the crankshaft, usually the belt side of the engine.
Harmonic balancers have nothing to do with engine overheat conditions.
did you disassemble the engine to determine the rod condition? some harmonic balancers will make a knocking sound when they go bad
They are both internally balanced, so it should work.
Most definetly, the harmonic balancers entire job is to keep the engine at a perfect idle. If it's not due to improper installation, then your cam bearings are toasted.
A miss or A collapsed engine mount or A imbalance caused by a failing component, harmonic balancers and torque converters are common.
I think they are one. Harmonic balancers usually are integrated as the main driving pulley in a serpentine system. Call a toyota parts department (dealer) to make sure.
That's an odd question, first who told you the harmonic balancer was bad? Balancers are mounted on the crankshaft at the factory, and it is actually just a weight attached to the end of the crankshaft to offest the firing of the pistons producing a smoother running motor. Harmonic balancers do not go bad, EVER, unless they are removed and damaged during engine repair (unlikely, very unlikely). They can be re-installed incorrectly after major engine repair, or simply left off due to negligence on some cars after major engine repair but I have never heard of a balancer going bad, as it is not a part that can actually fail. Harmonic balancer is a fancy word for weight, however if it has been removed or severely damaged due to impact I would strongly suggest having it fixed immeadetly as the unbalance can actually warp the crankshaft at high speeds and destroy your engine. Hate to keep driving this point home but harmonic balancers do not go bad, you should seek out another mechanic to check out your car, if I were still a mechanic I would only have told someone that if I was trying to rip them off due to their lack of automotive knowledge, or get them away from my shop because they were annoying or a problematic customer. (sorry)
Bigger motor, more recipricating weight, thus more vibration. Larger balancer is neds to counter the vibrations.
If bearings go bad they will "squeal"
A bad harmonic balancer can cause a knocking noise. The harmonic balancer doesn't actually produce the noise, but it can cause the noise in the engine.
