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 can fill the center of the bearing with grease and find something that is almost the same size as the bearing and place it in through the center of the bearing and take a hammer and hit whatever you are using and the force with the grease behind the bearing will force it out. You might have to hit it pretty hard and more then once but it will come out.

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. | ||

*They make a slide hammer with expandable fingers; it would be the safest way for the removal. This slide hammer is often called a blind hole puller or an internal bearing puller. | *They make a slide hammer with expandable fingers; it would be the safest way for the removal.

*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. |
This process will work on whatever vehicle you are working on that has a manual transmission. | This process will work on whatever vehicle you are working on that has a manual transmission. | ||
