The genuine XCMG Clamp with OEM number 800172840 is a heavy-duty hose clamp engineered for XCMG articulated dump trucks, wheel loaders, and off-highway equipment. This clamp secures coolant hoses, hydraulic lines, air intake ducts, and fuel hoses, preventing leaks, detachment, and chafing in the most severe mining and construction environments. Manufactured from high-grade spring steel or stainless steel with a corrosion-resistant coating, the XCMG 800172840 clamp provides consistent clamping force over a wide range of hose diameters and operating temperatures, ensuring leak-free connections and extended hose life.
The XCMG Clamp 800172840 is a small but critical component that ensures every hose connection remains tight under pressure, temperature changes, and machine vibration. Whether clamping a coolant hose to the water pump, a diesel return line, or a turbocharger air duct, a properly engineered clamp prevents leaks that could lead to overheating, fire, or loss of power. Genuine XCMG clamps are designed for the specific hose outer diameters and pressure ratings found on AD-series trucks.
In AD60 and AD80 dump trucks, the 800172840 clamp is used at the radiator lower hose, heater core connections, and fuel filter lines. Field data shows that genuine XCMG clamps maintain consistent clamping force even after 5,000 hours of thermal cycling, whereas aftermarket clamps often loosen or corrode, causing coolant loss and unscheduled stops.
The 800172840 clamp is manufactured from high‑carbon spring steel or 304 stainless steel, depending on the application. Spring steel clamps are tempered to provide constant tension, automatically compensating for hose compression set over time. Stainless steel clamps are used for corrosive environments (e.g., salt water spray, chemical exposure).
The standard finish is zinc‑yellow chromate or E‑coat, which withstands 500 hours of salt spray testing. For heavy-duty use, a black phosphate coating is available. The band edges are rounded to prevent cutting the hose, and the inner surface is smooth to avoid stress risers.
XCMG engineers have defined over a dozen clamp sizes for specific hose connections on AD‑series trucks. The 800172840 clamp is available in several clamping diameter ranges, each matched to a nominal hose OD. Using the correct clamp ensures uniform sealing pressure around the entire circumference. The clamp is marked with the XCMG part number and the size range (e.g., “32-50”).
For constant‑tension spring clamps, the installation tool (pliers) is not required – the clamp is slipped over the hose and released. The band width is optimized to handle up to 3.5 MPa in hydraulic applications. For high-pressure fuel lines, XCMG recommends using a double‑clip arrangement, which the 800172840 can accommodate.
To replace a clamp, first identify the type. For screw clamps, use a flathead screwdriver or 8mm socket to loosen the worm drive. For spring clamps, use pliers designed for constant‑tension bands (XCMG tool 800172840‑T). Remove the old clamp and inspect the hose for cracking or swelling. Clean the hose barb and slip on the new clamp before fitting the hose.
Position the clamp 2–5 mm from the end of the hose, ensuring the band covers the full depth of the barb. For screw clamps, tighten until the hose just begins to bulge around the barb (approximately 3–6 Nm). For spring clamps, release the pliers to allow the clamp to snap closed. After the first heat cycle, re‑tighten screw clamps.
Never reuse a spring clamp that has been removed – the spring tension may have diminished. Always replace with a new XCMG 800172840 clamp. For screw clamps, they can be reused if the threads are clean and the housing is not distorted. Inspect for rust or deformation annually and replace as needed.
Counterfeit clamps sold as 800172840 often use low‑carbon steel that rusts quickly, thin bands that cut into hoses, or incorrect spring tension. Symptoms include rust stains on the hose, coolant leaks, or the clamp loosening after a few months. Genuine XCMG clamps have a smooth, uniform finish and a laser‑etched part number and size range on the band.
Another common issue is the wrong clamp type for the application. Using a worm‑drive clamp on a high‑vibration coolant hose can cause the screw to back out. XCMG spring clamps are specifically designed for engine hoses where thermal expansion and contraction are extreme. Always use the clamp type specified in the XCMG parts catalog.
Corrosion: Aftermarket clamps may have only a light zinc plating that flakes off in salt environments, leading to rust that stains the engine. Genuine XCMG clamps undergo 500‑hour salt spray testing and are coated inside and out.
A loose or rusted clamp can cause a coolant leak that leads to engine overheating. Repairing an overheated engine can cost $2,500–$8,000. Replacing a faulty clamp with a genuine XCMG 800172840 costs less than $5. This is one of the most cost‑effective preventive maintenance actions you can take.
Preventive maintenance: During each oil change, inspect every hose clamp under the hood. Look for rust, distortion, or signs of leakage (white or brown stains). Replace any clamp that shows corrosion. Also, check screw‑type clamps for correct torque. A 10‑second inspection can save thousands in repairs.
Payback analysis: A genuine XCMG clamp costs ~$3. If it prevents one coolant leak that requires a tow ($500) and a $1,500 overheated engine repair, the savings are enormous. For a fleet of 20 trucks, switching to genuine XCMG clamps eliminates almost all leak‑related calls.
Every XCMG Clamp 800172840 is manufactured in an IATF 16949‑certified facility. Each batch undergoes 100% dimensional inspection, tension‑force verification (for spring clamps), and salt spray testing (sample per lot). XCMG provides a 24‑month warranty against material defects or loss of tension.
Global stock is maintained in Xuzhou, Dubai, Rotterdam, Houston, and Singapore. Emergency orders ship within 24 hours. Assorted clamp kits (part number 800172840‑KIT) containing 25 pieces of the most popular sizes are available for workshop use at a 15% discount. Each clamp is individually bagged and labeled with its size range.
To verify authenticity, scan the QR code on the bag – it links to the batch certificate showing material, coating thickness, and tension test results. Always insist on genuine XCMG 800172840; counterfeit clamps have been known to fail during operation, causing sudden coolant loss and catastrophic engine damage.
XCMG engineers tested the 800172840 clamp under extreme conditions: 10,000 thermal cycles from -40°C to +120°C, 200 hours of random vibration at 20g RMS, and 1,000 hours of salt spray. The clamp maintained constant tension, showed no corrosion perforation, and did not abrade the test hose. The zinc coating remained intact.
For highly corrosive environments (offshore, coastal mines), XCMG offers a stainless steel variant (800172840‑SS). This clamp is made from 304 stainless steel with a passivated finish, providing infinite corrosion life. It is recommended for all coolant hoses on trucks operating within 5 km of the ocean.
Vibration resistance: The spring clamp’s inherent flexibility absorbs engine movement without loosening. In field tests on AD100 trucks in Australian mines, genuine XCMG clamps showed zero loosening after 8,000 hours, while aftermarket worm‑drive clamps required re‑torquing every 500 hours.
