Land Rover Part Number: RTC171810 - Crank Bearings +0.010 - 3.5 V8
RTC171810 is a crankshaft main bearing set, sized +0.010, for 3.5L V8 engines. Fitted in the engine bottom end, these bearings support the crankshaft journals and restore the correct oil clearance after the journals have been machined undersize; this ensures the required hydrodynamic oil film and radial support for smooth crankshaft rotation. This size is used when the crankshaft has been reground to an undersize and the matched bearing size is needed to achieve correct clearance and oil pressure characteristics on the listed Defender, Discovery 1 and Range Rover Classic models.
