Main Bearing Set - Nissan Patrol GQ Y60 GU Y61 TB42 TB45 TB48

This Main Bearing Set is a critical internal engine component fitted within the engine block's main journals, where it supports the crankshaft. This is a complete set of standard-size bearings required for a comprehensive engine rebuild. Main bearings provide a low-friction, replaceable wear surface that allows the crankshaft to rotate smoothly under immense pressure and at high speeds.

You may need to replace your main bearings during an engine rebuild or if you are experiencing symptoms of bearing failure. Common signs include a persistent, deep knocking or rumbling sound from the bottom of the engine (often called 'bottom end knock'), low oil pressure readings, and the presence of metallic flakes in the engine oil.

Ignoring worn main bearings can lead to catastrophic engine failure. A spun or excessively worn bearing will cause a complete loss of oil pressure to the crankshaft, leading to metal-on-metal contact. This will quickly destroy the crankshaft and engine block, resulting in engine seizure and a repair bill far exceeding the cost of a standard rebuild.
