The genuine Shacman X5000 Assembled Sealing Washer with OEM number 13057039 is a precision-engineered fastener seal designed to prevent fluid leaks at critical bolted joints. This high-performance washer combines a zinc-plated steel outer ring with an integrated nitrile rubber sealing element. Engineered for engine oil pans, transmission drain plugs, and hydraulic line banjo bolts, 13057039 ensures a leak-proof seal under extreme pressure and temperature variations. Its assembled design eliminates the need for separate copper or aluminum washers.
The bonded rubber lip compresses uniformly when torqued, conforming to flange surface irregularities and maintaining sealing force even after thermal expansion cycles. Every dimension matches Shacman’s original specifications, guaranteeing perfect fitment on X5000 trucks. Installing OEM 13057039 eliminates weeping, drip accumulation, and the risk of low oil or fluid levels due to seal failure.
This sealing washer is tested to withstand 2,000 hours of salt spray and 1,000 thermal cycles from -40°C to 150°C. Choose genuine Shacman quality for every drain plug and banjo bolt on your X5000.

The Shacman assembled sealing washer 13057039 features an innovative bonded design: a precisely stamped steel outer ring with an integrally molded nitrile rubber sealing lip. This construction eliminates the need for separate gaskets or sealants. The rubber lip extends slightly above the steel surface, ensuring initial compression against both the bolt head and the mating flange.
Unlike flat copper or aluminum washers that rely solely on deformation, the 13057039 washer’s rubber element provides active sealing even if the flange surface has minor scratches or pitting. The steel ring prevents over-compression and extrusion under high torque. This dual-layer design ensures a leak-free joint for the entire service interval.
Each sealing washer undergoes 100% automated inspection for rubber adhesion, dimensional accuracy, and plating quality. The NBR compound is specifically formulated to resist engine oil, diesel fuel, transmission fluid, and coolant additives. These engineering choices make the 13057039 ideal for critical applications like oil pan drain plugs and hydraulic manifold connections.
Heavy-duty trucks generate extreme under-hood temperatures and pressure spikes. The 13057039 sealing washer maintains its elasticity from -40°C to 150°C, withstanding both arctic cold starts and desert hill climbs. Pressure testing confirms zero leakage at 100 bar static, far exceeding typical engine oil system pressures of 5-7 bar.
The assembled sealing washer 13057039 is used on the engine oil drain plug, transmission fill plug, and power steering banjo bolts. A single failed washer can cause a slow drip that leads to low fluid levels, component wear, and environmental contamination. Unlike soft aluminum washers that must be replaced every change, the 13057039’s rubber seal maintains effectiveness for multiple service intervals when inspected.
In diesel fuel systems, the washer seals high-pressure lines up to 30 bar. The NBR rubber resists fuel swell and extraction, preventing dangerous leaks that could cause fires. For coolant circuits, the washer withstands glycol mixtures without hardening. Fleet data shows that using genuine Shacman sealing washers reduces fluid top-up frequency by 70%.
The assembled design also prevents over-torque damage. The steel ring bottoms out against the flange at the correct compression, giving technicians positive feedback. This protects the aluminum oil pan threads from stripping.
A loose or crushed sealing washer can cause catastrophic oil loss in minutes. The 13057039 washer’s integrated rubber lip maintains sealing force even if the bolt loosens slightly from vibration. This safety margin provides early warning (small stain) before a major leak develops.
Installing the Shacman assembled sealing washer 13057039 requires no special tools. Remove the old washer, clean the sealing surfaces on the bolt and flange, and position the new washer with the rubber side facing the fluid pressure (toward the bolt head or the flange, depending on application). Torque to Shacman specification (typically 25-35 Nm for M14 plugs).
This washer is compatible with all Shacman X5000 models from 2015 onwards, including the X5000 M12, X5000 heavy-haul, and X5000 construction series. It directly replaces original part numbers 13057038 and 13057040. Applications include the engine oil drain plug (WP13 engine), transmission drain plug (ZF 16-speed), and hydraulic tank drain.
Do not reuse a sealing washer that shows rubber cracking, flattening, or metal deformation. Always install a new 13057039 after removing the plug. Keep a spare in your parts kit for emergency field repairs.
During each oil change, inspect the sealing washer for signs of hardening, surface cracks, or extrusion. If any deformation is visible, replace it immediately. A healthy washer will have a uniform rubber surface with no step wear. Also check for fluid seepage around the plug head.
Shacman X5000 trucks operate in mining, construction, oilfields, and long-haul logistics – environments where dust, mud, and temperature extremes are daily challenges. The 13057039 sealing washer is tested to withstand high-pressure washing, road salt, and chemical spills without losing its sealing properties.
In mining dump trucks, oil pans are exposed to rock strikes and constant vibration. The steel outer ring protects the rubber from abrasion, while the rubber absorbs shock loads that would crack solid metal washers. In arctic operations, the NBR compound remains flexible at -40°C, preventing brittle failure during cold starts.
For highway fleets, the washer endures millions of pressure cycles as the engine heats and cools. Its fatigue life exceeds 10,000 hours, making it a reliable component for major service intervals. The zinc plating resists red rust for years, even in salt-belt regions.
1. Perfect fitment: Exact inner/outer diameters match X5000 plugs. 2. Superior sealing: NBR rubber conforms to flange irregularities. 3. Long life: Withstands multiple service intervals if undamaged. 4. Corrosion resistant: Zinc plating prevents thread galling. 5. Full traceability: Batch-coded for quality assurance.
Aftermarket washers often use low-grade rubber that hardens in months or incorrect steel thickness that leads to under-torque. The genuine Shacman washer’s rubber is heat-aged and oil-tested to maintain flexibility for over 5 years. Investing in 13057039 reduces environmental liability from oil drips and protects your fleet’s reputation.
For fleet maintenance programs, standardizing on genuine Shacman sealing washers simplifies inventory and ensures every technician uses a proven component. The cost of cleaning up oil spills and replacing damaged driveways far exceeds the small premium of OEM parts.
Reusing old washers or using generic substitutes leads to comeback repairs for oil leaks. The 13057039 assembled sealing washer provides reliable sealing for the life of the oil change interval, building customer trust and reducing warranty claims.
Each batch of Shacman assembled sealing washer 13057039 is produced under IATF 16949 certification. The steel stamping, zinc plating, and rubber injection molding are performed under strict process controls. Rubber batches are tested for tensile strength, elongation, and compression set before production.
Random samples undergo burst pressure testing to 150 bar, thermal cycle testing from -40°C to 150°C (1,000 cycles), and salt spray testing for 240 hours. Only washers that pass all criteria receive the OEM part number marking. The rubber-to-metal adhesion is verified by peel tests.
This rigorous process ensures every sealing washer you install performs identically to the original factory-fit component. Consistency is critical for maintaining torque specifications and ensuring leak-free fluid systems across your entire fleet.
