Is the harmonic balancer supposed to wobble?
Is the harmonic balancer supposed to wobble?
Noticeable Harmonic Balancer Wobble When the rubber isolator begins to deteriorate, the balancer usually begins to separate, creating a noticeable wobble when the engine is running.
What happens if harmonic balancer is loose?
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.
What would cause a crank pulley to wobble?
If the fan-belt pulleys that bolt to the harmonic balancer are dismounted, bent, or distorted, it may cause the crankshaft pulley to wobble. Sometimes, some dirt may get trapped under the pulley. Furthermore, the crankshaft pulley tends to wobble if it isn’t appropriately torqued.
How do I know if my harmonic balancer has slipped?
There is a scribe mark on the face of the balancer you can see while it is installed. The mark is chiseled across between the center hub and the outer ring. Rotate the engine with a 3/4 wrench and look closely for the mark. If the mark on the hub is not aligned with the mark on the ring then it is slipped.
Can a harmonic balancer slip?
The harmonic balancers found on many vehicles are constructed as two pieces of metal with a rubber layer in between to dampen the vibrations. If the layers separate or slip, the timing marks, which are usually stamped into the front of the pulley, can shift and thus throw off the placement of the timing marks.
Should the crank pulley wobble?
The crank pulley is pretty vital and affects the smoothness of the engine. If its wobbling then its bad. You may get away for years running it this way, or it may damage the main bearings.
Can harmonic balancer cause no start?
Bad Ignition Timing/No Start Without a functioning harmonic balancer your vehicle’s ignition timing will be thrown off. The condition results in your vehicle being unable to start.
