Crankshaft pully bolt removal

Crank pulley bolt tightens clock wise and loosens counter clock wise. You will need a puller to remove the balance as it has a keyway to hold it on.

Cant get crank pully bolt to brake lose

Take the starter off and wedge a block of wood or a pry bar against the ring gear teeth on the flywheel. That would hold the crankshaft steady. Are you using a good stout breaker bar to try and loosen the bolt? If you have access to an impact gun, that is what shops often use. Any friends or neighbors with an impact tool? If you can drive the car to a shop, you could have them loosen it for you, then tighten it just enough to get you back home to finish working on it.
Here is a method I have used and it works great, but do it at your own risk, it is not recommended: With the car on the ground, use a 1/2 inch breaker bar and socket on the bolt. The end of the bar needs to be resting on the ground, and situated so that when the starter is bumped over-just a quick bump of the starter-the engine crankshaft turns just a little bit, but the breaker bar will keep the bolt from turning with the crank-it will loosen the bolt. Just one quick bump from the starter and I was able to loosen the pulley bolt on a Chrysler this way. Lots of DIY mechanics have done this, but as I said, not recommended. But if carefully done, and breaker bar is situated in right position-it will loosen the bolt. Post back if you don't understand. Good luck.

I'm trying to change the belts for my 92 tercel but some how cant find the tension pulley. Can anyone please help me. I need to change both belts.

It appears that your car is equipped with multiple v-belts, rather than a serpentine belt so there most likely aren't tensioner pullies. Here is some general info that may help.

Alternator To adjust the tension of the alternator drive belt on older models, loosen the pivot and mounting bolts on the alternator. Using a wooden hammer handle, or a broomstick as a prying device, move the alternator one way or the other until the proper tension is achieved. Do not use a screwdriver or any other metal device such as a pry bar, as a lever. Newer models use a tension adjusting bolt. Loosen the pivot bolt and the locking bolt, then turn the tension adjusting bolt until proper tension is achieved. Tighten the bolts securely, run the engine about minute, stop the engine then recheck the belt tension. Air Conditioning Compressor A/C compressor (always use caution when working near the A/C compressor to avoid damaging the refrigerant lines) belt tension can be adjusted by turning the tension adjusting bolt which is located on the compressor tensioner bracket. Turn the bolt clockwise to tighten the belt and counterclockwise to loosen it. Air Pump To adjust the tension of the air pump drive belt, loosen the adjusting lever bolt and the pivot bolt. Move the pump in or out until the desired tension is reached. NOTE: The tension should be checked between the air pump and the crankshaft pulley on cars without air conditioning. On cars with A/C the tension should be checked between the compressor and the crankshaft pulley. Power Steering Pump Tension on the power steering belt is adjusted by means of an idler pulley (some models may use just a lower adjusting bracket setup, similar to the alternator adjustment service procedure). Loosen the lock bolt and turn the adjusting bolt on the idler pulley until the desired tension is felt, then tighten the lock bolt.

Whats the best way to remove the crankshaft pully on a 1996 geo prizm (small engine) Can't seem to remover the bolt

Put a socket and breaker bar on the bolt, set the bar against the control arm, then turn the starter just briefly to spin the crankshaft and push the breaker bar against the control arm. This should loosen the bolt.

How to remove bottom pully bolt 1.6 hdi 307

you need to peg the crankshaft near your gearbox. There is a hole in engine block for this purpose. Find this hole and insert an allen key (thick enough to fit in there). Turn the crank pully with ratchet in clockwise while try to find out the locking hole in crankshaft near gearbox by pushing allen key through engine block hole. You'll hear a click and the allen key goes fully inside. Now your crankshaft is locked and you can open (anticlockwise) the pully bolt.

Which way do you turn the crankshaft pulley bolt to loosen it?

It turns left (counterclockwise) to remove. An impact wrench is best if you can get one on it.

If you don't use an impact wrench, you may need to somehow keep the crank from turning when you loosen the bolt.

One way is to pull the belt tighter to put more tension on the crank pulley.

There are other creative ways I've used. If you have any trouble let me know.
