How to examine and replace the pilot bearing in 3.0L six cylinder engine on BMW 325i?

The pilot bearing is installed into the center of the dual-mass flywheel, and provides support for the free end of the transmission input shaft on manual transmission vehicles. It can only be examined once the clutch has been removed. Using a finger, rotate the inner race of the bearing and check for any roughness, binding or looseness in the bearing. If any of these conditions are evident, the bearing must be replaced. To remove the bearing, first remove the flywheel. The bearing must be pressed out using a hydraulic press with a drift that bears only on the inner bearing race. The bearing is pressed from the engine side of the flywheel and out of the clutch side. Note: The act of pressing the bearing out will render it unusable - it must be replaced. For installation, using a suitable socket or piece of pipe, that bears only on the hard outer edge of the bearing, press the new bearing into the flywheel until it contacts the shoulder. Then, install the flywheel.

BMW 325i Pilot Bearing

The BMW 325i Pilot Bearing centers the input shaft of the transmission within the crankshaft to minimize friction and allow more fluid shifting. The Pilot Bearing is small in size. It may be fitted on the rear of the crank or within the flywheel. Moreover, it offers a low friction surface. Thus, the input shaft is able to spin at engine speed when the clutch is depressed. As a result, no drag will occur between clutch plates, which prevents grinding. The Pilot Bearing should have precise tolerances as defined by BMW to prevent any chatter or vibration from the clutch. The Pilot Bearing, also termed a pilot bushing, of the early 325i was sintered bronze and supports the shaft on an oil impregnated sleeve. Later models employed a Pilot Bearing equipped with a caged needle roller capable of rolling on hardened needles for greater rpm stability and load distribution. The two forms perform a similar function but are manufactured differently, lubricate differently, and carry different loads. The bronze style applies a film of embedded oil that is static and is suited to everyday driving. The needle style uses rolling elements which cut friction further and are fitted for heavier loads. A worn bearing will squeal, shudder, or make shifting difficult, no matter which style is fitted. BMW owners should replace the Pilot Bearing as soon as possible for proper gearbox alignment on the 325i and enhanced drivability.
