Clutch Pilot Bearing (Press-in style) 911 Turbo, 930 1976-1979 up to engine # 6890504 (up to engine # 6891231 California). We machine the housings for these to very tight tolerances from special quality cold-drawn and hardened steel bars that resist distortion and warpage even at elevated temperatures. This is critical to bearing life and operation because the insert bearings used in these parts rely upon the housing to establish the roundness and installed i.d. of the bearing (i.e.: the new bearings are not round out of the box). After black oxide plating we install an O.E.M. felt seal and a genuine INA (also O.E.M.) bearing.
