Genuine VOLVO Crankshaft Thrust Washer Set — Engine Axial Positioning Thrust Plate
The Genuine VOLVO Premium Heavy-Duty Crankshaft Thrust Washer Set (Part Numbers: 21141955 / VOE21141955 / 20405899), also known as crankshaft thrust bearing and axial thrust gasket, is a high-precision wear-resistant part matched for VOLVO D7E and D6E electronic common rail diesel engines. It is installed inside engine block main bearing seat, closely fitted with crankshaft thrust surface. Different from main bearings bearing radial load, this set mainly controls crankshaft axial front-back movement, offsets gear transmission impact and torque direction thrust. Replacing worn and scratched thrust washers during engine bottom overhaul can effectively fix crankshaft displacement, keep piston and connecting rod in correct alignment, avoid cylinder body wear and prevent major engine mechanical failures.
Core Technical Advantages
Multi-Layer Copper-Lead Alloy StructureSteel base plus high-load anti-friction alloy layer, strong bearing capacity, excellent fatigue resistance suitable for instantaneous peak torque impact.
Built-In Precision Lubrication Oil GrooveReasonable oil channel design forms stable high-pressure oil film during operation, isolates metal direct contact and reduces abrasion loss.
Good Particle Embedding PerformanceFine surface structure can absorb tiny metal impurities in engine oil, avoid crankshaft journal scratch damage.
Micron Level Precision Thickness ControlStrictly manufactured according to original factory standards, accurately restore engine specified crankshaft axial clearance after installation.

Critical B2B Procurement & Maintenance Guidelines
B2B Procurement Strategy
Crankshaft thrust washer is a must-replace part for engine bottom major repair. Long-term use, insufficient oil pressure and dirty engine oil will cause rapid wear of anti-friction layer, leading to crankshaft axial shift and a series of linkage failures. It is recommended that spare parts distributors and engine maintenance factories stock this model in batches, and match it with main bearing shells, connecting rod bearings, connecting rod bolts and crankshaft oil seals to form complete engine bottom overhaul spare parts packages.
Common Wear Failure Symptoms
Obvious heavy impact knocking sound inside crankcase when engine load changes
Frequent oil leakage at front and rear crankshaft oil seals after replacement, caused by excessive axial movement
Bronze metal fine scraps appear in engine oil and oil filter, obvious wear of thrust anti-friction layer
Stop equipment safely, cut off main power supply, drain engine oil and remove oil pan. Disassemble the main bearing cap equipped with thrust washers and take out old parts. First check crankshaft thrust contact surface for scratches and grooves; severely worn crankshaft must be repaired synchronously. Thoroughly clean bearing seat sundries and oil dirt. Install new thrust washers correctly, ensure the grooved lubrication surface faces crankshaft side, forbidden reverse installation. Coat enough assembly oil on the surface, install bearing cap and fasten main bearing bolts according to standard torque. Use dial indicator to detect crankshaft axial clearance strictly to meet factory data. Manually rotate crankshaft to confirm smooth operation without jamming before assembly completion and trial run.
