the harmonic balancer is bonded to the hub on a rubber strip
the pulley is the balancer and they do fail from the load of the drive belt
if it is wobbling then the bonding is failed and eventually the pulley will separate from the hub and could go through the radiator or any thing else near
I have witnessed a pulley separating from the hub, hitting the ground under the car and seriously injuring the leg of a passer by.
it was on a dodge chrysler -valiant
I suggest that you consider changing it asap or get an opinion from an accredited service shop familiar with your vehicle
i dont think is your harmonic balancer that dont make any sound check all the pulleys cose to change the harmonic ba... you havto remove and change your crank pulley along with it
your crankshaft pulley aka Main pulley is bolted on to a harmonic balancer and the balancer sits on the crankshaft get a timing gun and figure out where the mark is on the harmonic balancer and there should be a metal plate somewhere on the timing chain cover with a mark to make the that when the number 1 piston is all the way up the marks are aligned or your timing is off
Did the crankshaft pulley separate from the harmonic balancer? No bolts missing? This happens once in a while. Just replace the harmonic balancer assembly (and probably the belt).
no. there should not be any wobble to your harmonic balancer pulley! any wobble to the bottom pulley,means it's out of balance. either a belts too tight,or a harmonic balancer bolts loose. the other belts contribute to the wobble once it begins. check the tourque on the harmonic balancer bolt. it should be about 180 footlbs thank you for choosing fixya.com.
yes just loosen your power steering pump to get the belts loose then get an air gun or figure out a wawy to keep the pulley still and it will come right off
you have a pulley locking up that is breaking belt. with belt off spin pulleys by hand and feel for anything abnormal. wobbles, sticks or bind. due this for all pulleys ran by that belt u will find your problem
Well if it is a 4 cylinder the timing marks would be small hole in camshaft lined up with little dot on head at 12 o'clock position and the crank with the pulley on should line up with 0 on the timing indicator. If it is a 6 cyl then the marks would be- camshafts both with dots up and lined up with indicaters on heads and crank timing mark on 0 with the harmonic balancer installed. Hope this helps.
