Starting a little more gently you pull out the transmission and then proceed to take of the clutch. The pilot bearing is there to receive the forward end of the transmission input shaft in the form of bearing pressed on the end of the crankshaft and bugs service when the clutch is removed. Clean the bearing, using a blade, and check for wear and damages; in case of wear, use a new bearing. It can be performed with a special nut-buster, or, if necessary, with the help of hydraulic instruments. Hydraulic method: look for a strong steel bar that should be slightly smaller than bearing i.d, usually of a size 19/32 inch. Cob the bearing and the region behind it with thick grease, and try to avoid as much air in the depression as possible. Place the bar in the bearing bore and strike it gently with a hammer and this will in a way exert pressure on the grease to push the bearing out. This type requires that the grease is cleaned from the crankshaft after removal. Before fitting the new bearing, one is required to spread a thin layer of oil over the outer surface of the bearing, and then drive it into place with the bearing driver made out of a steel bar and a soft-faced hammer so that the radius is now turned outwards from the bore. The other steps of installation are the reverse of the steps of uninstallation as mentioned above.
