Crankshaft main bearings, standard size (STD + 0.25, so-called first grind bearings), 20 mm wide and 2.00 mm thick, with an internal diameter of approximately 51 mm for Yanmar tractors of the Yanmar EF352T, Yanmar EF453T, Yanmar F18, Yanmar F20, Yanmar series F22, Yanmar F24, Yanmar FX24 , Yanmar 3TNE84, Yanmar 4TNE84 , Yanmar EF352T, Yanmar EF453T with Yanmar 3TNV88, Yanmar 4TNV88 and other engines.
Engine main bearings are semicircular rings that are installed in special grooves (holders) in the engine block, between the crankshaft (main shaft) and the engine block (applies to the center shaft journals) in order to eliminate any play occurring during engine operation. The main bearings support the shaft, ensuring the correct position of the shaft in relation to the engine block so that the power generated is transferred as smoothly as possible.

The first signs of wear of the main bearings are an unnatural, constant knocking noise coming from the engine. Worn bushings must be replaced with new ones as soon as possible, replacing a faulty element too late may result in serious damage to the shaft, connecting rod or engine.
