Genuine VOLVO Thrust Washer 20850116 Specification

Genuine VOLVO Crankshaft Thrust Washer Set — Axial Positioning Thrust Plate

The Genuine VOLVO Premium Heavy-Duty Crankshaft Thrust Washer Set (Part Number: 20850116 / VOE20850116), known as crankshaft thrust bearing and axial thrust gasket, is a high-precision wear-resistant component specially developed for VOLVO D4D, D5E, D6E, D6J, D6H mid-range diesel engines. Mounted inside engine block main bearing seat, it closely fits crankshaft thrust surface. Different from radial load bearings, this set effectively limits crankshaft front and rear axial displacement, buffers gear meshing impact and torque direction thrust force. Replacing aged and worn thrust washers during engine bottom overhaul can accurately fix crankshaft position, keep connecting rod and piston in correct running track, avoid abnormal wear of cylinder liner and prevent serious engine mechanical faults.

Core Technical Advantages

Multi-Layer Copper-Lead Alloy Structure Steel base combined with high-strength anti-friction alloy layer, strong load-bearing capacity, stable performance under frequent peak torque impact.
Surface Dynamic Pressure Oil Groove Design Reasonable lubrication channel ensures sufficient oil supply, forms stable oil film isolation, effectively reduces running friction loss.
Excellent Impurity Embedding Property Fine and smooth surface can absorb tiny metal impurities in lubricating oil, effectively protect crankshaft journal from scratch damage.
CNC Precision Thickness Control Strictly manufactured in accordance with original factory standards, quickly restores engine standard crankshaft axial clearance after installation.

Critical B2B Procurement & Maintenance Guidelines

B2B Procurement Strategy

Crankshaft thrust washer is a mandatory replacement part for engine bottom major repair. Long-term operation, insufficient oil pressure and inferior lubricating oil will accelerate the wear of anti-friction layer, cause crankshaft axial drift and trigger a series of associated failures. It is recommended that spare parts suppliers and engine maintenance factories stock this model in batches, match it with main bearings, connecting rod bearings, high-strength connecting rod bolts and crankshaft oil seals to form complete bottom overhaul kits, and support overall engine matching maintenance.

Common Wear Failure Symptoms

Obvious dull impact knocking sound inside crankcase when engine load and working condition change
Frequent oil leakage failure of front and rear crankshaft oil seals after replacement
Visible bronze fine metal scraps in engine oil and oil filter elements

Standard Overhaul Installation Operation
Park the equipment stably, cut off the main power switch, drain engine oil and remove oil pan. Disassemble the matched main bearing cap and take out old thrust washers. Prior to installation, carefully inspect the wear state of crankshaft thrust contact surface; repair and polish severely scratched journals in time. Thoroughly clean bearing seat interior to remove carbon deposits and sundries. Install new 20850116 thrust washers correctly, ensure the grooved lubrication surface faces crankshaft side, strictly prohibit reverse installation. Evenly coat assembly lubricating oil on the working surface, install bearing caps and fasten bolts according to standard torque. Use dial indicator to accurately measure crankshaft axial clearance to meet factory technical requirements. Manually rotate crankshaft to confirm smooth operation without jamming before assembling accessories and running-in test.
