Are tensioner pulley reverse thread?

Are tensioner pulley reverse thread?

The bolt for the tensioner pulley is left hand thread(reverse) The bolts for the tensioner assembly are regular threads.

Is the tensioner pulley supposed to spin?

Idler pulleys spin in order to move belts to different places. Tensioner pulleys, which are spring-loaded, provide pressure to a belt that drives other pulleys while simultaneously easing the strain on that belt.

Should a new idler pulley spin freely?

The new idler pulley seems extremely tight when it’s bolted to the engine. It definitely will not spin freely.

Should all pulley spin freely?

The only pulleys you should be able to turn by hand when the serpentine belt is not in place are: the water pump, alternator, and power steering pump pulleys. 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.

Is crankshaft pulley and harmonic balancer the same thing?

Is a crankshaft pulley and harmonic balancer the same thing? – Quora. No! They are two different things. The harmonic balancer slides onto the front of the crankshaft which has a keyway on it to keep it from slipping and a bolt and wide washer holds it in place.

What does a bad harmonic balancer look like?

Engine vibration One of the first symptoms of a potential problem with the harmonic balancer is engine vibration. If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively.

What makes a harmonic balancer go bad?

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.

How much should it cost to replace a harmonic balancer?

Cost of Harmonic Balancer Replacement On average for most vehicles, it can cost about $200 to replace a harmonic balancer. The cost of replacing the harmonic balancer varies mainly due to the type and model of the vehicle and the type and brand of parts used.

Can a harmonic balancer cause a misfire?

Noisy Belt Operation or Damage The harmonic balancer also acts as a pulley for your vehicle’s drive belts so when it begins to fail your engine’s belts may slip, operate noisily or become damaged.
