Pulley Removal Tips

Obviously, a good penetrating oil and soaking go a long way (we recommend PB Blaster).  If you have tried that without any luck, here are some tips we have gathered from our customers.  If you have other ideas, let us know at support@cvfracing.com
 
Alternator Pulley:  This is a standard right handed thread on most American automobiles.  Use a box end wrench to hold the pulley nut and then us an Allen key on the alternator shaft.  This works best if you have an Allen key that fits on a socket...that way you can get more torque on the alternator shaft.  If this doesn’t work or if you strip the Allen key, another method is to wear a heavy leather glove and hold the alternator fan while spinning off the nut with an air impact wrench.  Put the V-belt on the pulley and then put the other end of the V-belt in a vise, clamping the V-belt tight around the pulley.  Once the pulley is secured with the V-belt, have a go at it with the impact wrench.  If none of these ideas work, or you don’t have an impact wrench, remove the alternator from the vehicle and bring to your local auto parts store where they should be able to help you out.
 
Power Steering Pulley: 
 
Keyed On:  This is a standard right handed thread on most American automobiles.  The center nut can be removed using a box end wrench on the nut and an Allen key (similar to the method used for the alternator pulley).  If that doesn’t work, you can try to get a good grip on the pulley with a leather glove and try an impact wrench.  If you have trouble holding onto the pulley with a gloved hand, you may want to use an old V-belt to hold the pulley. 
 
Pressed On:  You will need to get a power steering pulley puller.  Do not use a standard 3 jaw puller because it will damage the pulley.  This puller can cost between $40 and $100 so if you don’t have a friend who has one, we would recommend renting one from your parts store.  AutoZone will loan you a power steering puller for free using their loan a tool program (you just have to give them a fully refundable deposit).  Some parts stores may even remove the pulley for you.
 
Here are a couple of  helpful videos we have found on YouTube:
 
 
 
Crank Pulley:  This is a standard right handed thread on most American automobiles.  Our best recommendation is to remove the radiator and use an air impact wrench (an impact ratchet wrench may fit without removing the radiator).  With a manual transmission you can put it into 4th or 5th gear and apply the emergency brake to keep the engine from rotating..  This will keep the engine from turning over.  If the crank pulley is stuck on the crank, you can use a generic puller to remove.  Here is a link.  (Note:  This will damage an aluminum pulley)
 
 
We have also heard stories of customers wedging a breaker bar on the frame and bumping the starter.  If you try this technique, please be sure to remove the spark plug wires or spark plugs so that the engine doesn’t start.  Also, be absolutely certain that the breaker bar is secured and will not fly around a destroy something or someone.  Above all be careful if you use this risky technique!  We are not liable if it destroys something or someone.
 
Here is a video showing the starter bump technique...again...BE CAREFUL!  Notice there are no people any where nearby when the engine is turned over and under no circumstances should you have someone hold the breaker bar.  You could also end up damaging your flywheel teeth or stripping the nut on your crank. 
 
 
Water Pump Pulley:  This one is pretty straightforward.  The toughest part is slicing up your knuckles on the radiator fins.
