OEM 800371917 The XCMG Face Seal (800371917) is a genuine OEM precision‑moulded static sealing component engineered to provide reliable, leak‑proof sealing between mating flanges, covers, and housings in XCMG articulated dump trucks. This high‑performance face seal, identified by part number 800371917, is critical for preventing fluid and contaminant ingress at bolted joints, ensuring long‑term system integrity and component protection in the most demanding mining, quarrying, and construction environments.
Manufactured from high‑grade nitrile rubber (NBR) or fluoroelastomer (FKM) with precision moulding and a durable anti‑extrusion design, the 800371917 face seal delivers exceptional sealing performance, temperature resistance, and long‑term durability under extreme pressure, vibration, and temperature fluctuations (-40°C to +150°C). Its precision‑engineered cross‑section and hardness guarantee a perfect fit and optimal compression without modification.
The 800371917 face seal features an optimised profile for uniform compression, a corrosion‑resistant material formulation, and a design that resists extrusion and twisting during assembly, making it an indispensable component for maintaining leak‑free joints, preventing fluid loss, and maximising uptime in your ADT fleet.
The 800371917 Face Seal is manufactured using precision compression moulding and advanced curing processes, ensuring consistent cross‑sectional dimensions and material properties across every unit.
Its high‑grade nitrile rubber (NBR) or fluoroelastomer (FKM) construction provides robust defence against fluid leaks, contaminant ingress, and pressure loss in static flange and cover joints.
The face seal’s precision‑engineered circular cross‑section ensures uniform compression when the joint is tightened, creating a positive seal that prevents oil, coolant, or hydraulic fluid from escaping.
This sealing component effectively prevents external contaminants such as dust, water, and abrasive particles from entering critical assemblies, protecting bearings and gears.
The Shore A hardness of 70 provides the ideal balance between compressibility for sealing and resistance to extrusion under high clamping forces.
In extreme environments such as open‑pit mines and aggregate quarries, the 800371917 delivers reliable, long‑lasting sealing performance for your ADT’s flanged joints.
Articulated dump trucks rely on face seals to maintain leak‑tight joints at critical flanges, covers, and access plates, preventing fluid loss and system contamination.
The 800371917 face seal acts as a vital barrier, ensuring that oil, coolant, and hydraulic fluid remain contained, preserving system pressure and lubrication.
A degraded or improperly fitted face seal can allow fluid leakage, leading to reduced performance, environmental contamination, and potential safety hazards.
By maintaining a leak‑tight seal, this face seal helps keep hydraulic systems operating at peak efficiency, reducing the risk of component starvation and wear.
The seal’s excellent resistance to petroleum‑based fluids ensures that it does not swell, soften, or degrade when exposed to common lubricants.
Regular inspection and replacement of face seals is a simple yet effective way to prevent costly fluid leaks and unplanned downtime.
The 800371917 is produced using high‑precision molding dies that achieve dimensional tolerances of ±0.08 mm on cross‑section, ensuring a perfect seal in every application.
The high‑grade nitrile rubber (NBR) compound, specifically formulated for petroleum fluid resistance, provides excellent strength, flexibility, and durability.
The material exhibits outstanding resistance to hydraulic oils, engine oils, diesel fuel, and coolant, with minimal volume swell even after prolonged exposure.
The Shore A hardness of 70 provides the optimal balance between sealing effectiveness and resistance to extrusion under high‑pressure static conditions.
The face seal’s circular cross‑section ensures uniform compression around the entire circumference, distributing sealing force evenly against both mating surfaces.
Every unit undergoes 100% dimensional inspection and visual quality checks to guarantee interchangeability with OEM specifications.
The 800371917 face seal is molded from 100% virgin nitrile rubber, specifically formulated for superior resistance to petroleum fluids, abrasion, and temperature extremes.
The compound exhibits excellent compression set resistance, retaining over 85% of its original sealing force after 70 hours at 100°C, ensuring long‑term reliability.
The material meets ASTM D2000 classification standards, confirming its suitability for demanding sealing applications in off‑highway equipment.
The face seal’s low compression set means it maintains a tight seal even after thousands of thermal cycles and pressure fluctuations, preventing fluid bypass.
The high tensile strength and elongation at break ensure that the seal can withstand installation stresses without tearing or permanent deformation.
The material is free from volatile plasticizers that can leach out over time, ensuring consistent sealing performance throughout its service life.
The 800371917 is designed for straightforward installation using standard workshop tools and no special equipment.
To replace a worn face seal, first clean the flange or housing groove thoroughly to remove old seal material, dirt, and debris.
Lubricate the new 800371917 face seal with clean oil or the system fluid to prevent twisting or pinching during assembly.
Gently place the seal into the groove, ensuring it sits evenly without twisting or rolling, and then bring the mating flanges together.
Tighten the bolts to the recommended torque specification to achieve the correct compression without over‑compressing the seal.
The entire replacement process typically takes less than 15 minutes, minimising downtime during routine maintenance.
Investing in the 800371917 Face Seal delivers significant long‑term savings by preventing costly fluid leaks and contamination‑related failures.
Replacing a failed hydraulic pump or valve due to contaminated oil can cost thousands of dollars – costs that this face seal helps to avoid.
Field data shows that replacing aged, hardened seals with genuine XCMG face seals reduces fluid leak incidents by up to 70%.
The seal’s durable NBR construction means it typically outlasts multiple service intervals, providing exceptional value over the vehicle’s lifetime.
By maintaining proper sealing and fluid containment, the seal also contributes to system efficiency and reliability, reducing operating costs.
Fleet operators have reported a marked reduction in fluid‑related breakdowns after equipping their ADTs with genuine XCMG sealing components.
