MAIN CRANKSHAFT BEARINGS. Main crankshaft bearings are critical components of the engine crankshaft assembly designed to support and allow smooth rotation of the crankshaft within the engine block. They create a sliding bearing surface between the crankshaft journals and the block saddles, minimizing friction and ensuring stable engine operation under load. The bearings are manufactured from multi-layer anti-friction materials with a steel backing and specialized coating engineered to withstand high loads, temperature and oil pressure. Proper clearance and correct bearing grade selection are essential to maintain a stable oil film and prevent crankshaft journal damage. Wear or failure may result in low oil pressure, knocking noise from the lower engine area, excessive crankshaft play or journal scoring. Causes may include oil starvation, contaminated oil, overheating or excessive engine load. Our catalog includes genuine OEM main crankshaft bearing sets, quality aftermarket replacements and standard or oversize repair dimensions. Used bearings are not recommended for critical engine rebuilding without professional inspection. Selection is based on VIN number, engine type, bearing size class and part number. Timely replacement ensures stable oil pressure, smooth crankshaft rotation and extended engine service life.

The source data describes this item as “Вкладиші колінвала корінні”. Correct operation of this part supports the related assembly and the vehicle functions designed around it. Wear may show as unusual noise, oil or air leakage, unstable engine operation, reduced power, increased consumption, or diagnostic faults. A single symptom does not always prove that this exact component has failed, so power supply, wiring, mountings, or adjacent parts should be checked as appropriate before replacement. Before purchase, compare the OEM number, engine code and revision, identification marks, dimensions, mountings, and adjacent-part configuration. OEM 87836620 is the primary reference, but an identical product name does not guarantee compatibility across different vehicle specifications. Before purchase, compare identification and appearance with the old part and verify compatibility by VIN.
