Genuine VOLVO Main Bearing 20850106 Specification

Genuine VOLVO Crankshaft Main Bearing Shell Set — Mid-range Engine Main Journal Bearing

The Genuine VOLVO Premium Heavy-Duty Crankshaft Main Bearing Shell Set (Part Numbers: 20850106 / VOE20850106 / 22967564), commonly known as crankshaft main bearing, is a high-load core engine part exclusively designed for VOLVO D4D, D5E, D6E, D6J, D6H mid-range diesel engines. Installed inside engine block main bearing seats and matching bearing caps, it fully bears the overall gravity and rotational torsion force of crankshaft assembly. Different from connecting rod bearings bearing single-cylinder impact load, this main bearing set undertakes long-term stable supporting work. Replacing worn, scratched and peeling main bearings during engine major overhaul can restore standard lubricating clearance, stabilize overall engine oil pressure, reduce running vibration and guarantee reliable operation of bottom rotating assembly.

Core Technical Advantages

Multi-layer Alloy Composite Structure Integral steel base combined with copper-lead anti-friction alloy layer, strong bearing capacity and excellent fatigue resistance against sudden torque impact.
Built-in Oil Hole & Oil Distribution Groove Precision reserved oil passage ensures smooth circulation of pressure lubricating oil, forms complete dynamic pressure oil film and avoids dry friction abrasion.
Good Particle Embedding Performance Soft surface layer can adsorb tiny metal impurities in engine oil, effectively protect crankshaft journal from scratch damage.
Micron-level Precision Manufacturing Strictly produced according to original factory size standards, accurately restore engine standard radial assembly clearance after installation.

Critical B2B Procurement & Maintenance Guidelines

B2B Procurement Strategy

Crankshaft main bearing is an essential fast-moving part for engine major repair. Long-term operation will cause gradual wear of alloy anti-friction layer, resulting in increased clearance and insufficient engine oil pressure. It is recommended that spare parts wholesalers and engine repair workshops stock this product in batches, match with 20850116 thrust washers, connecting rod bearings, high-strength connecting rod bolts and crankshaft oil seals to form complete bottom overhaul kits, supporting full set matching repair of mid-range VOLVO engines.

Common Failure Manifestations

Engine often triggers low oil pressure alarm, more obvious under hot engine idle condition
Low-frequency heavy knocking sound inside crankcase, sound increases when accelerating and loading
A large amount of copper alloy metal debris precipitates in engine oil and oil filter

Standard Overhaul Installation Rules
Stablely park the machine, cut off power supply, drain engine oil and remove oil pan, disassemble main bearing caps in standard sequence. Take out old bearings and check wear degree. Before installation, use micrometer to measure crankshaft journal roundness and taper, repair or replace worn crankshaft in time. Thoroughly clean bearing seat inner wall without any sundries. Align positioning buckle of new main bearings accurately and install in place. Evenly daub assembly oil on alloy working surface, keep steel back clean and dry. Fasten main bearing bolts strictly in accordance with factory torque and angle standards. Use Plastigage to detect bearing clearance to ensure it is within qualified range. Manually crank crankshaft to confirm flexible rotation without jamming before assembly and running-in test.
