Usually the balancer is all by itself then you transfer the pulleys to the balancer

Noisy engine


some noises in the engine come from water pump bearing failure. idler pulley bearing failure. If you have a viscous fan hud that can give a noise. Also check that the harmonic balancer isn't coming apart and slipping

Pulley on crankshaft is rattling bad is there a bearing


Billy you have the main bearings on the crankshaft, but you said a rattling noise, these pulleys are bolted to the harmonic balancer check the bolts that attach the pulley to the balancer to see if they are tight. Sometimes they can work their way loose. If it were a main bearing the engine would have a slight shake to it or in other words while the vehicle is idling the motor would shake along with a loss of oil pressure on your gauge in the vehicle. By the rattling it can be two things that come to mind either the harmonic balancer is coming apart or the pulley is coming loose from the balance. Hope this helps let me know what you find.

I have a 2000 nissan sentra my harmonic balance is bad according to a autozone person it moves when the car is on and he told me it needs to be replaced because it has play i need to replace and find out...


The harmonic balancer is integrated with the crankshaft pulley, and if replaced requires taking the bolt out from the side of the 4 cyl. engine.

I would recommend that an experience engine rebuilder perform the service.

Inspect the Harmonic Balancer:

The harmonic balancer (vibration damper) is inspected for signs of wear in its center bore.
  • Also inspect the rubber mounting for indications of twisting and deterioration.
  • The outer ring can slip, causing an out of balance condition. Replace any harmonic balancer that has slipped.
  • With the cylinder head removed and the piston at top dead center (TDC), make a visual comparison. Do the timing marks for TDC on the timing cover and damper appear to be accurate.
  • Be sure the damper is the correct one for the vehicle. The wrong one can be worse than none at all.
  • Sometimes a damper can become loose on the crank. Check the keyway for wear that can result from improper damper installation, the wrong size key, or a loose damper hub to crank fit.
  • Be sure all pulleys are straight. A damaged pulley can force a crankshaft to bend during engine operation.
This is a general guide on replacing the harmonic balancer, but there are other instructions that the rebuilder would follow to actually do the service for you:

To remove the harmonic balancer, the cylinder head and timing cover must be removed and the piston should be at top dead center (TDC).
  • Install the vibration damper by pounding it on, or use a special installation tool.
  • Generally, the damper is installed unit it bottoms out against the oil slinger and the timing sprocket.
  • If in doubt, install the water pump and pulley, and then pound the damper into place until its pulley aligns with the water pump pulley.
  • It is advisable to use the installation tool, because pounding on the damper can cause stress on the crank thrust bearing surface.
  • It is best to stand the engine block on end and support the crankshaft if the damper must be pounded on.
  • Some vibration dampers are not pressed-fit on the crankshaft.
  • Be sure to install a large washer behind the damper retaining bolt on these engines; otherwise, the damper might fly off, causing damage and a safety hazard.

HARMONIC BALANCER


I have a '94 Tempo, it had a "ticking" sound. It was the "harmonic balancer" (crankshaft pulley) a local mechanic changed it for $60, the part cost me $120 (I work for a Ford dealership) $180 without employee discount. you can get one for much less at a junkyard if you can find one. Good luck, Sean
