Product Features

• Structure: Precision-stamped from high-strength, wear-resistant bronze alloy with a smooth, polished surface. The set includes multiple half-moon shaped washers, some with locating tabs for correct positioning.

• Performance: Withstands high axial thrust loads and engine temperatures up to 150°C, maintaining precise crankshaft alignment. The bronze alloy provides excellent friction resistance and durability.

• Design: Engineered to match the original crankshaft and main bearing housing dimensions, ensuring a precise fit and consistent thrust clearance.

Core Function

• Limits the axial movement of the crankshaft, preventing it from shifting forward or backward and ensuring proper alignment with the connecting rods and pistons.

• Absorbs the thrust forces generated during engine operation, protecting the main bearings and cylinder block from wear and damage.

• Maintains optimal crankshaft positioning, which is essential for proper valve timing and engine balance.

Key Features and Benefits of Thrust Washer 201V01114-5501

• Precision-Machined Surface Finish: Engineered to tight tolerances (surface roughness Ra ≤ 0.8μm), this thrust washer minimizes crankshaft axial play and reduces frictional heat generation during high-load operation.
• High-Grade Bimetal Construction: Steel-backed with aluminum-tin alloy overlay, delivering superior fatigue resistance and excellent conformability to crankshaft thrust faces under sustained pressure.
• OEM-Equivalent Dimensional Accuracy: Manufactured to match the original SINOTRUK specification for part number 201V01114-5501, ensuring drop-in fitment without machining or modification.
• Optimized Oil Groove Design: Strategically placed lubrication channels maintain a stable hydrodynamic oil film, protecting against metal-to-metal contact during cold starts and heavy acceleration.
• Extended Service Life: Withstands continuous operating temperatures up to 150°C and intermittent peaks beyond 180°C, reducing replacement frequency and lowering total cost of ownership.
• Corrosion-Resistant Coating: Anti-corrosion treatment prevents degradation during storage and transit, so the part arrives ready to install regardless of shipping conditions.

Technical Specifications

Application Scenarios – Where This Thrust Washer Performs

The Thrust Washer 201V01114-5501 is purpose-built for SINOTRUK’s heavy-duty powertrain lineup. It finds its home inside the crankshaft assembly of the following vehicle platforms:

• SINOTRUK HOWO A7/T7H Tractor Trucks: Long-haul logistics operations where engines sustain high RPM for extended periods, demanding consistent thrust bearing performance over 500,000+ km service intervals.
• SINOTRUK SITRAK C7H Heavy-Duty Trucks: Premium-tier highway tractors operating in demanding intercity freight corridors across the Middle East, Africa, and Central Asia.
• SINOTRUK HOWO Dump Trucks (Mining Spec): Off-road mining and construction applications where shock loads and steep-grade operation place extreme axial stress on the crankshaft assembly.
• SINOTRUK Concrete Mixer Trucks: Continuous PTO-driven operation creates sustained axial loading patterns that accelerate thrust washer wear — making quality replacement parts essential for uptime.

Every time a driver engages the clutch on a steep grade or a loaded trailer pushes back against the drivetrain during deceleration, this thrust washer quietly absorbs the force that would otherwise damage the crankshaft. It’s the unsung guardian of your engine’s rotating assembly.

Frequently Asked Questions About Thrust Washer 201V01114-5501

What is the function of a thrust washer in a SINOTRUK engine?

The thrust washer controls axial movement (end play) of the crankshaft within the engine block. Without a properly functioning thrust washer, the crankshaft can shift longitudinally under load, causing catastrophic contact between rotating and stationary components. The 201V01114-5501 maintains crankshaft end play within the specified 0.07–0.27 mm range for SINOTRUK MC/D series engines.

How do I know when the Thrust Washer 201V01114-5501 needs replacement?

Common indicators include excessive crankshaft end play (measurable with a dial gauge), unusual knocking sounds during clutch engagement, oil pressure fluctuations, and visible scoring on the crankshaft thrust face during engine teardown. If measured end play exceeds 0.30 mm, immediate replacement is recommended to prevent crankshaft damage.

Is this thrust washer compatible with both MC11 and MC13 engines?

Yes. Part number 201V01114-5501 is specified by SINOTRUK for use across their MC11 and MC13 engine platforms, as well as the D10 and D12 series. The dimensional specifications are shared across these engine families for the thrust washer position. Always verify against your engine’s specific parts catalog for confirmation.

What causes premature thrust washer failure?

The most common causes include misalignment during installation, contaminated engine oil (abrasive particles erode the soft overlay), insufficient oil pressure at startup, and excessive clutch-related axial loading from worn release bearings. Using a quality thrust washer like the 201V01114-5501 with proper installation technique significantly extends service life.

Can I order this thrust washer in oversize thickness for reground crankshafts?

METTLEAD can supply oversize thrust washers upon request for engines with reground crankshaft thrust faces. Contact our technical team with your required thickness specification, and we will confirm availability and lead time for your specific requirement.

What is the minimum order quantity for the 201V01114-5501?

We accommodate orders ranging from sample quantities (for testing and validation) to full container loads for established distribution partners. Our flexible MOQ policy is designed to support both new customers evaluating quality and high-volume repeat buyers seeking the best unit economics.
