A pilot bearing is a sleeve-type bearing that reduces the amount of friction to which your vehicle's transmission is exposed. The pilot bearing is composed of two parts: the bearing seat and a bearing case. A pilot bearing puller removes the bearing case from the bearing seat, allowing you to replace a worn bearing case with a new one.
Place the pilot bearing puller directly over the pilot bearing seat. Secure the puller by adjusting the puller's legs around the bearing seat and tightening the fixing screws to prevent the legs from slipping.
Lower the jaws of the puller into the bearing case. Turn the yoke on the pilot bearing puller to expand the jaws against the inside of the bearing case. Adjust the jaws until the hooked tips are secure beneath the rim of the bearing case or the yoke refuses to turn.
Tighten the extracting nut to prevent the puller handle from slipping against the crossbar. Use the crescent wrench to make sure the extraction nut is snug against the crossbar.
Turn the handle of the pilot bearing puller to remove the bearing case from the bearing seat. When the bearing case is fully extracted, loosen the yoke until the jaws release the bearing case.
