There are several ways to remove the pilot bearing from the crankshaft. The pilot bearing/bushing is used with a manual transmission '''only'''. And, it is in your best interest for the bearing to be removed when changing from a manual transmission to an automatic transmission. | There are several ways to remove the pilot bearing from the crankshaft.

First when removing the bearing you will be removing the transmission. So, as anytime, when doing these changes be safe and have the vehicle properly secured when lifted in the air, if you do not have a lift. Be sure to use the proper jack stands for the weight of the vehicle in question, and, if possible, have someone there with you while performing the work. Please do not place vehicle on blocks of wood or concrete blocks, and, if possible, and you have access to a transmission stand, use it by all means. |
Vehicle needs to be on a good level surface. After the transmission has been removed and cleared from the vehicle, you will remove the flexplate/flywheel. Then, if you look at the end of the crankshaft, you will see the bushing. It is where the shaft of the transmission will ride when installed. The nose of the shaft sits inside the bearing. Now you can either rent or buy a puller for this. It's a small slide hammer puller with fingers on it that you will place in the bearing and use it to pull the bearing out. If you do not have access to a puller here are a few other ways of removing the bearing. | Vehicle needs to be on a good level surface.

You might have to hit it pretty hard and more then once but it will come out. '''When using something like grease, please wear safety glasses. The force of the grease can cut the skin, or even put your eye out. Also watch out for flying pieces of metal.''' |
*When using the grease/toilet paper method wear gloves or wrap a rag around whatever you are using to hit with the hammer to help prevent flying debris. | *When using the grease/toilet paper method wear gloves or wrap a rag around whatever you are using to hit with the hammer to help prevent flying debris. | ||

*If you can't find a tool to use to fit the bearing, you can use a 3 inch 1/2 Inch drive extension to place in the center of the bearing and force it out. But by all means if you can use the small fingered slide hammer, do so. | *If you can't find a tool to use to fit the bearing, you can use a 3 inch 1/2 Inch drive extension to place in the center of the bearing and force it out.

*If you have a brass or bronze pilot bushing, an alternate method can be used as well. Use a tap and cut threads into the bushing. Then screw in a bolt and bottom it out inside the bushing so it contacts the crank. Then just keep on turning and it will pull the bushing out.Works real well if you have a tap where as you may not have a piece of stock to fit the bearing inside diameter.It is a little safer as it takes the hammer out of the equation. | *If you have a brass or bronze pilot bushing, an alternate method can be used as well.
