Connecting rod bearings / STD + 0.25 / Mitsubishi S3L

Connecting rod bearings in size STD + 0.25 (so-called first-cut connecting rod bearings) for tractors with Mitsubishi S3L and other engines.

Connecting rod bearings are components whose primary function is to reduce friction at the connecting rod's connection to the crankshaft. The bearings are two separate, semicircular elements that, when assembled, form a circle. Bearings (though not all types) also have a small groove or notch through which lubricant is distributed. The most common causes of rapid bearing wear include: using oil with the wrong viscosity, improper bearing installation, failing to adhere to oil change intervals, low engine oil level, and overloading the engine, which has not reached the proper operating temperature.
