  Q: How do you renew the pilot bearing and remove the flywheel on BMW 2500?

  A: This is important if you intend to renew the pilot bearing, otherwise to do the latter, you have to remove the clutch or the automatic transmission. Use a Kukko extractor or a similar one together with a ball-bearing and cover plate, felt ring, and cap. Replace the bearing in the reverse manner and always make sure that it is packed with high quality, high melting point grease. Place the cover plate with the side of raised letters on the exterior of the unit and in the case of the felt ring needed for this position, it should be pre-soaked in hot tallow before installation. Thoroughly knock the bearing cap into proper position and then reassemble the clutch or automatic transmission. When it comes to flywheel removal, you may need to take off the clutch for manual transmission or the automatic transmission for automatic cars. In regard to models that do not have flywheel locating sleeves, it is necessary to draw the position of the flywheel in relation to the crankshaft. Place the flywheel in a non-rotating position using tool 7007 or an equivalent tool; undo the mounting bolts and dismantle the flywheel whilst bearing the weight of the flywheel. Remove the flywheel from the crankshaft, and, if the vehicle had a torque converter, also remove the drive plate. As for the flywheel, note that it was fixed to the crankshaft by using what appears to be one-shot expansion bolts; dispose of these and get replacements for subsequent tightening. If the ring gear of the flywheel is broken, this can be replaced, but since the gear has to be heated for installation, it is recommended that this be done at a service station. To refit the flywheel and drive plate in reverse order new expansion bolts should be fitted, and Loctite LT red be applied to the bolt threads; the bolts (when to be fitted finger-tight), and then tightening of the bolts should be in sequential turn and to the equal level of torque.
