It’s not okay to drive with a bad harmonic balancer. The bouncing crankshaft will wear on the main bearings. It can also tear up drive belts and possibly come apart posing a danger to people and property.
If you take out the bolt and look at the inside of the balancer hole the end of the crank should be flush with the machined area of the balancer where the bolt and washer tighten down. This is a small block Chevy, the end of the damper sits an inch or two past the end of the crank….
Cost of Harmonic Balancer Replacement On average for most vehicles, it can cost about $200 to replace a harmonic balancer.
To properly tighten the balancer bolt, you have to lock the motor up and tighten it with a Torque wrench. Usually, wedging the flywheel is the way to go. If you want the easy way out, you could use a impact wrench and tighten it up.
A faulty balancer can result in a knocking, rattling, or squeaking sound that corresponds with engine speed. … Also, a balancer that’s beginning to fail can cause abnormal movement from the drive belt or automatic drive belt tensioner, resulting in clicking or squealing noises when the engine is running.
Are harmonic balancers interchangeable? All harmonic balancers ARE interchangable but you may need to get the right pulley for the power steering. Some had a rubber mount (old style. around the hub and newer ones were all iron and smaller but they DO interchange without affecting balance.
Multiply the damper diameter by 3.14159 (Pi), then divide by 360°. The answer is the distance in inches for one degree. For a 30° timing mark, multiply this value by 30. Cut out this distance on a strip of paper to avoid a straight line measurement.
If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively. The shaking will become even more pronounced, and therefore dangerous to the engine at high speeds.
If the torque is not set properly, the engine vibration and running of the drive belt over the harmonic balancer can cause the harmonic balancer pulley to loosen and fly off the engine. Whistling noises may indicate looseness in the belt. Every car is different.
It should just go on. Tight yes, but not tight enough to wreck any tools trying to get it on and off.
Is a harmonic balancer bolt reverse thread? Yes, that bolt is normal thread, counterclockwise loosens it. The engine turns the opposite direction as the bolt removal direction to gaurantee that it won’t back out.
The air conditioning compressor has a clutch on it that should spin freely as well but it will not be rotating the internals of the compressor. … That you cannot rotate either cam or crankshaft pulleys by hand is completely normal. If you were able to rotate them bare handed, THEN you would have a problem.
Over time, the crankshaft harmonic balancer can go bad from constant exposure to chemicals, the elements, or from old age. If this happens, the crankshaft may develop cracks and ultimately fail.
And certain engines they might only last 50,000 miles or less than 10 years. This is a good example – because it’s got such a massive piece of rubber – you can see the rubber literally tears apart into two sections.
Yes, it is possible
The bigger problem with over tightening a square taper is that crank arm can be deformed to the point where it will not stay tight. I always use a torque wrench when tigtening crank bolts to avoid over tightening.
How about pull out your torque wrench, put it at the 120 or so ft lbs that the bolt requires for tightening (verify with the FSM), and try to loosen until you’ve put that amount or torque into removing. That should give you a benchmark on how much force is required. Or start lower, like 90 ftlbs.
The reason for such a nifty product to exist is after time the Neoprene timing cover seal wears a deep groove into the steel snout of the harmonic balancer. This allows oil to leak from the timing cover and if the oil leak is left neglected, road dirt and grime attracts to oil-covered areas and sticks.
Without the belts that go around the crankshaft pulley, there would be no air conditioning, no power steering, no alternator, and no water pump. You can do damage to the engine bearings if you don’t have it. You need to replace it.
As a rule of thumb, the longer the stroke and greater the torque, the larger the diameter and mass. However, larger dampers can affect the acceleration and revving ability of an engine, so the right diameter and mass can help you strike the right balance.
Nearly all 350s came with an 8-inch balancer because of their relatively long stroke. An 8-inch balancer was used on the short-stroke, 3.0-inch-stroke, 302 Z/28 engines because those mills were intended for road racing.
you can still put a 305 balancer on a 350 and use the same timing mark and set timing right?
A half-inch drive impact gun might be a great tool for removing a stubborn crankshaft pulley bolt. A torque wrench has also been proven to be a helpful tool for correctly securing it.
