Maintain smooth crankshaft operation and reliable engine performance with this Genuine Nissan Main Bearing Set, designed to suit Nissan Patrol GQ Y60 and GU Y61 models fitted with the TB42, TB45, and TB48 petrol engines. This OEM main bearing set is installed between the engine block and crankshaft, providing a precision low-friction bearing surface that supports the crankshaft while maintaining correct oil clearances and engine oil pressure.

Over time, main bearings can wear due to high engine kilometres, inadequate lubrication, contaminated engine oil, overheating, or heavy engine loads. Worn bearings can cause low oil pressure, bottom-end knocking, increased engine vibration, and excessive crankshaft wear. If left unrepaired, bearing failure can lead to severe engine damage requiring a complete engine rebuild.

Manufactured to Genuine Nissan specifications, this precision-engineered main bearing set provides exact fitment, correct bearing clearances, and outstanding durability. It is the ideal replacement during a complete engine rebuild, crankshaft replacement, or bottom-end engine overhaul to restore factory engine performance and long-term reliability.
