The genuine XCMG Spiral Clamp with OEM number 800163482 is a heavy-duty hose clamp engineered for XCMG articulated dump trucks, wheel loaders, and off-highway equipment.
This spring-loaded spiral clamp provides constant tension on hose connections, compensating for thermal expansion, hose compression, and vibration.
Manufactured from high-grade spring steel with a corrosion-resistant zinc‑nickel plating, the XCMG 800163482 spiral clamp delivers reliable, leak‑free sealing on coolant, air, and fuel hoses in the most demanding mining environments.
Its unique spiral design eliminates the need for periodic re‑tightening, making it ideal for hard‑to‑reach locations on AD‑series trucks.
The XCMG Spiral Clamp 800163482 provides a unique constant‑tension solution for hose connections in high‑vibration environments.
Unlike worm‑drive clamps that can loosen over time due to thermal cycling, the spiral design maintains a consistent clamping force throughout the life of the hose.
This is critical on AD‑series trucks, where engine vibration and temperature swings from -40°C to +110°C are common. A loose clamp leads to coolant leaks, air intake leaks, and potential engine damage.
The spiral spring action automatically compensates for hose compression set, eliminating the need for periodic re‑torquing. Field data from mines in Chile shows that genuine XCMG 800163482 clamps reduce leak incidents by 75% compared to worm‑drive clamps.
The 800163482 spiral clamp is wound from high‑carbon spring steel (SAE 1070), which is heat‑treated to achieve optimal spring properties.
The material retains its elasticity even after millions of compression cycles, ensuring that the clamp does not take a permanent set.
The zinc‑nickel plating provides excellent corrosion resistance, withstanding 720 hours of salt spray testing without red rust.
This coating is also resistant to engine oil, coolant, and diesel, making it suitable for under‑hood applications where fluid exposure is inevitable.
The clamp ends are formed with smooth, rounded edges to prevent cutting into the hose rubber, a common problem with poorly made spiral clamps.
The XCMG spiral clamp 800163482 is a direct replacement for original part numbers 800163482A, 860124595, and 860298769.
It is available in three size ranges to cover all coolant, air, and fuel hoses on AD‑series trucks: 18–32 mm (small coolant lines), 32–50 mm (radiator hoses), and 50–70 mm (air intake ducts).
The clamp is identified by a color code (yellow, blue, or red band) indicating the size range for easy selection during maintenance.
For turbocharger oil drain lines operating at higher temperatures, XCMG offers a stainless steel version (suffix “-SS”) rated to 250°C.
The clamp should be installed using the special pliers (800163482‑TOOL) that expand the spiral evenly without damaging the coating.
To install a spiral clamp, first ensure the hose is fully seated on the fitting. Open the clamp using the special pliers, expanding it just enough to slide over the hose.
Position the clamp over the barb, then release the pliers. The clamp will snap into place, applying uniform radial pressure.
Do not use ordinary pliers, as they can damage the coating or distort the spiral. After installation, tug on the hose to ensure it is secure.
Inspect the clamp every 500 hours. Look for signs of corrosion, cracks, or loss of spring tension. Replace any clamp that shows deformation or rust.
Unlike screw clamps, spiral clamps should never be reused once removed – the spring may have taken a set.
Always keep a few spare clamps in the truck’s emergency kit for field repairs. Service life in normal conditions is over 8,000 hours.
Counterfeit spiral clamps sold as 800163482 often use low‑grade carbon steel that rusts rapidly, leading to spring failure.
Symptoms include visible rust, loss of clamping force (hose can be rotated by hand), or the clamp snapping during installation.
Genuine XCMG clamps have a uniform silver‑grey zinc‑nickel finish, a laser‑etched part number, and a holographic label on the packaging. The wire ends are smooth and rounded.
Another common issue is incorrect spring rate. Aftermarket clamps may be too weak to seal high‑pressure coolant lines or too strong, cutting into the hose.
The XCMG 800163482 clamp is calibrated to exert 200–400 N of clamping force, depending on size. Test the force by trying to rotate the hose – if it spins easily, the clamp is defective.
Incorrect sizing: A counterfeit clamp may have the wrong inner diameter, leading to either an overly loose or an impossibly tight fit. Always check the color code against the XCMG size chart before installation.
A failed hose clamp can cause a sudden coolant leak, leading to engine overheating and potential head gasket failure – repairs that can cost $5,000+.
Replacing all suspect clamps with genuine XCMG 800163482 spiral clamps costs approximately $2–5 per clamp. This small investment prevents catastrophic failures.
Predictive maintenance: During daily walkarounds, look for signs of coolant crystallization or dust trails around hose connections – these indicate a leaking clamp.
If you see rust on a spiral clamp, replace it immediately. Also, if a clamp feels loose when you try to rotate the hose by hand, it has lost tension.
For fleets, proactive replacement of all coolant and air intake clamps every 4,000 hours virtually eliminates leak‑related downtime.
Payback analysis: A single clamp costs ~$3. If it prevents one engine overheat that requires a $2,500 repair, the ROI exceeds 800 times the cost.
Every XCMG Spiral Clamp 800163482 is manufactured in an IATF 16949‑certified facility. Each batch undergoes 100% dimensional inspection, spring force testing, and salt spray sample testing.
Random samples are subjected to 500,000 compression cycles to verify fatigue life. 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.
Bulk packs of 50 clamps (part number 800163482‑B50) are available for fleet customers at a 20% discount. Each clamp is individually bagged with a desiccant.
To verify authenticity, scan the QR code on the packaging – it links to the test certificate showing spring force, coating thickness, and batch number.
Always insist on genuine XCMG 800163482; counterfeit clamps have been known to snap under vibration, causing hose blow‑off and engine damage.
XCMG engineers tested the 800163482 spiral clamp under extreme conditions: 10,000 thermal cycles from -55°C to +150°C, 1,000 hours of random vibration at 25g RMS, and 1,000 hours of salt spray.
The clamp maintained 95% of its initial clamping force and showed no signs of cracking or corrosion. The zinc‑nickel coating remained intact on all surfaces.
For engines that operate in very high‑temperature environments (e.g., turbocharged engines with exhaust temperatures near 800°C in the bay), XCMG recommends the stainless steel version (suffix “-SS”), which withstands up to 250°C continuous.
The spiral clamp design also reduces the risk of chafing against adjacent components, as the smooth outer profile has no protruding screw or ear.
This makes it ideal for tight engine bays where clearance is limited. The constant tension also prevents the hose from “cold‑flow” creep, a common problem with worm‑drive clamps on silicone hoses.
