Connecting rod bearings / Yanmar EF352T / EF453T / Yanmar 3TNV88

Connecting rod bearings (connecting rod %C3% B3d-yanmar-ef352t.html">6-01-140-03 , 12900-23001) of standard size + 0.50 (so-called third-grind bearings) for Yanmar tractors of the Yanmar EF352T, Yanmar EF453T series and others.

The connecting rod sliding 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 also have a small groove or cut through which the lubricant is distributed. The most common reasons for rapid wear of the 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,
• overload of the engine which has not reached the proper 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.
