Could you help me how to use bearing pullers
Bearing pullers are specialized mechanical tools that pull the bearingsoff of axle shafts.
Although there are many different types and designs, they all work on the sameprinciple.
A set of jaws will hook onto the outer sides of a bearing lining or bearingcase.
Bearing pullers with jaws that hook onto the inside of a bearing lining arecalled a "blind-hole bearing puller.
A central bolt or a slide hammer is then used to put reverse pressure onto thejaws that grip the bearing lining until it comes off and away from the axle.

1.Measure the diameter of the bearing that needs to be removed. Bearing pullers come in several different sizes so be sure to acquire the correct size bearingpuller for your needs.. They can be rented from any auto or hardware store.
2.Unscrew the center bolt with your hand. Place the bearing puller over thebearing to be pulled off. On pullers with jaws, line up the center puller boltonto the shaft and place the jaws behind the bearing. On blind hole pullers,insert the jaws into the inner diameter of the bearing lining. Turn the centershaft to spread the jaws and grasp the bearing.
3.Position the shaft of the puller onto the axle shaft. Turn the bearing pullershaft clockwise with a wrench. Continue turning until the bearing is pulled completelyoff. On a bearing puller with a slide hammer, once the jaws are in place, pullback forcefully on the hammer to unseat the bearing.
