Yes, in most cases you can. The crankshaft pulley is bolted to the front of the crank shaft by either 1 large bolt and thick washer, or by 4 small bolts around the edge of inside of the pulley, depending on model.

Remove all belts that are driven by the crankshaft pully and then grasp the pully to see if it is loose in some way.

To remove the large bolt(if that's what you have), will require the use of a strap wrench which can be gotten for the free loan-A-tool from Autozone.

Only if the end of the crankshaft was damaged in some way would you have to replace the crankshaft.

make sure the pulley bolt is tight then check the pulley for being bent. if these 2 things are good then you may have a bent crankshaft at the pulley end or worn crank bearing causing it to wobble.

Pulley wobble on front of 1991 Mazda MX5 Miata engine with short nose crank


Hello, Unless Mazda forges the pulley onto the crankshaft, the pulley is usually a separate piece. You do not know which piece is bent and there may be a possibility that the pulley is coming loose attributing to the wobble.

Clearance is a big issue in working on these transverse mounted motors. You may possibly be able to get a socket on the crankshaft bolt to tighten it. Its a guess on whether there is enough room to switch the crankshaft pulley without dropping the engine cradle out of the body.

I can not say whether the crank bolt is a left or right handed thread. But with a little more research you may be able to find out. Use the Web Browser for a specific part search.

Was the timing belt replaced recently? If your crank pulley/harmonic balancer is wobbling, it is probably loose. Do not run the engine, if this part falls out, it will cause more damage.

The bottom pulley for the drive belt is wobbling and making a loud sound. do i need to replace the pulley and is it the bearings in the pulley?


The bottom pulley on any engine is attached directly to the torsional vibration damper which is attached to the crankshaft. That pulley drives the serpentine belt and has no bearings. First thing you need to do is find out if the pulley bolts have become loose or if the damper on the crank is loose.
If you find the pulley loose, if the bolt holes are not elongated, just tighten it back up. If the damper is loose, remove it from the engine (puller usually necessary) and inspect the crank snout and the alignment key for wear. Any damage to the damper requires that it be replaced. If the crank snout is severely damaged, that requires that the crank itself be replaced (very expensive).

Humming noise and wobbling pulley 1995 Corolla


Maybe, you would have to remove the belts and then take a look at all the pulleys, it could be a pulley or a bad waterpump, or even something in the timing belt, like a timing belt pulley or tensioner pulley or waterpump,the best way to find out is to remove all the belts and then start the motor and listen for the noise, if the noise is still there with the belts removed then its something in the timing belt, but is the noise goes away then its something with the belts a pulley or a alternator, you would have to inspect all pulley and the acc, hope this helps,
