Connecting rod bearings / STD / Yanmar YM1500 / Yanmar 2TR15

Nominal connecting rod bearings of standard size, width 21.30 mm , thickness 1.40 mm and outer diameter after assembly about 54 mm, for Japanese tractors and mini tractors of the Yanmar brand YM series with Yanmar engine and others .

Connecting rod bearings are elements whose main task is to reduce friction at the point of connection of the connecting rod to the crankshaft. The bearings are two separable, semicircular elements that, when installed, create a circle. The bearings (though not all types) also have a small groove or cut through which the lubricant is distributed. The most common reasons for rapid wear of connecting rod bearings are:

• using oil with incorrect viscosity parameters,
• incorrect installation of bearing shells,
• failure to comply with oil change intervals,
• low engine oil level,
• overloading the engine, which has not reached the correct temperature,

The first signs of wear of connecting rod bearings are an unnatural, steady knocking coming from the engine. Worn bearings must be replaced with new ones as soon as possible, replacing the faulty element too late can cause serious damage to the shaft, connecting rod or engine.
