The genuine XCMG Auxiliary Tank Bracket with OEM number 332107557 is a heavy‑duty structural component engineered for XCMG articulated dump trucks, wheel loaders, and off‑highway equipment. This bracket provides robust support for auxiliary hydraulic tanks, fuel reservoirs, or coolant expansion bottles, ensuring secure mounting that withstands severe vibration, shock loads, and chassis flex. Manufactured from high‑strength steel plate with precision‑formed bends, robotic welding, and a corrosion‑resistant E‑coat finish, the XCMG 332107557 auxiliary tank bracket guarantees long‑term reliability and exact fit in extreme mining, quarry, and construction applications.
The XCMG Auxiliary Tank Bracket 332107557 is a critical structural component that secures auxiliary hydraulic tanks, fuel reservoirs, or coolant overflow bottles to the chassis frame. In articulated dump trucks, these tanks are subjected to constant vibration, thermal expansion, and frame flexing. A properly supported tank prevents fatigue cracking at mounting points, hose damage, and potential fluid leaks that could cause environmental hazards or system failure.
On AD60 and AD80 trucks, this bracket is typically used for the auxiliary hydraulic oil tank located on the left side of the chassis. Field data shows that replacing a cracked or corroded bracket with a genuine XCMG 332107557 restores original alignment and reduces tank‑related failures by over 65%.
The 332107557 bracket is fabricated from HSLA steel plate (minimum yield 450 MPa) that is laser‑cut and formed in precision dies. All welds are performed by robotic MIG welders under controlled parameters, ensuring consistent penetration and minimal spatter. The assembly is then stress‑relieved to eliminate residual welding stress, preventing distortion or crack initiation over time.
The E‑coat (electrophoretic) coating provides 500 hours of salt spray resistance, outperforming simple powder coating or paint. This is essential in mining environments where salt, calcium chloride, or acid mine drainage can accelerate corrosion. The coating also protects internal surfaces that are inaccessible after installation.
The XCMG auxiliary tank bracket 332107557 is a direct OEM replacement for original part numbers 332107557A, 332107557B, and supersedes earlier versions with reinforced gussets. The bolt hole pattern matches the chassis mount exactly, requiring no drilling or modification. The tank side features slotted holes to accommodate rubber isolators, allowing slight movement to absorb thermal expansion.
For earlier AD45 trucks, this bracket may be used as an upgrade over the original stamped‑steel bracket, providing 40% greater fatigue life. The kit includes a new set of M16 grade 10.9 bolts and anti‑seize compound. Always verify chassis hole alignment before final tightening.
To replace the auxiliary tank bracket, first drain the tank or support it with a lifting strap. Remove the old bracket by unbolting the four chassis bolts and the tank mount bolts. Clean all mounting surfaces on the chassis and tank frame, removing rust or old gasket material.
Position the new XCMG 332107557 bracket against the chassis, aligning the four M16 holes. Hand‑start bolts, then torque to 280 Nm (206 ft‑lb) using a cross pattern. Install the rubber isolators into the bracket slots, then lower the tank onto them. Torque M12 tank nuts to 80 Nm (59 ft‑lb).
After 50 hours of operation, re‑torque all fasteners. Inspect the bracket welds for cracks during every engine service. If you notice any gap between the bracket and chassis or the tank shifting, inspect for damaged isolators or loose bolts. Replace the bracket immediately if any weld crack is found.
Counterfeit brackets sold as 332107557 often use mild steel with poor weld penetration. Symptoms include weld cracking within 500 hours, bending under tank weight, and rapid corrosion (rust bleed through thin paint). Genuine XCMG brackets have a uniform dark gray E‑coat, robotic weld beads with consistent ripple pattern, and a laser‑etched part number on the back face.
Another issue is incorrect hole alignment. Aftermarket brackets may have holes mis‑located by 2–3 mm, causing bolt binding or stress on the tank mounts. Always test‑fit the bracket loosely before tightening – genuine XCMG brackets will align without prying. Check the thickness of the material – genuine uses 6 mm plate; counterfeits often use 4 mm thin plate that flexes.
Corrosion protection: Non‑genuine brackets may be painted without E‑coat, leading to rust within months in humid environments. The genuine XCMG coating can be identified by a slight orange‑peel texture and uniform coverage inside drilled holes.
A failed auxiliary tank bracket can allow the tank to sag or rock, causing hose connections to stress‑crack and leak. A single hydraulic oil leak can result in environmental fines and costly fluid replacement. Replacing a cracked bracket costs about $80–120, but preventing a tank rupture and fluid spill saves thousands.
Predictive maintenance: During daily inspections, visually check the auxiliary tank bracket for paint cracks (indicative of metal fatigue), rust stains, or missing bolts. Apply a pry bar to the bracket – it should not flex more than 1 mm. Listen for tank rattle during engine idle. If any movement is detected, inspect the bracket welds and mounting bolts.
Payback analysis: The XCMG bracket costs approximately $95. If it prevents one tank replacement ($800), fluid loss ($300), and one day of downtime ($2000), total savings exceed $3,200. ROI is achieved instantly. For a fleet of 10 trucks, annual savings on tank and bracket‑related repairs can exceed $15,000.
Every XCMG Auxiliary Tank Bracket 332107557 is produced in an ISO 3834‑certified welding facility. Each bracket undergoes 100% dimensional inspection, dye penetrant weld testing, and coating thickness verification. Random samples are fatigue‑tested to 2 million cycles. XCMG provides a 24‑month warranty against weld failure or corrosion perforation.
Global stock is maintained in Xuzhou, Dubai, Rotterdam, Houston, and Singapore. Emergency orders ship within 24 hours. XCMG also offers a bracket and isolator kit (part 332107557‑KIT) including the bracket, rubber isolators, and all mounting bolts. Bulk orders for fleet customers qualify for volume discounts.
To verify authenticity, scan the QR code on the packaging – it links to the weld map and coating test report. Always insist on genuine XCMG 332107557; counterfeit brackets have caused catastrophic tank failures and environmental spills.
XCMG tested the 332107557 bracket under extreme conditions: -45°C cold soak, +60°C engine bay heat, and 5,000 hours of random vibration on a test stand simulating the worst haul roads. The bracket showed no weld cracks, no deformation, and less than 0.2 mm of bolt hole elongation. The E‑coat remained intact with no undercut rust.
For corrosive environments (salt mines, coastal operations), the standard E‑coat is sufficient for 5+ years. For extreme chemical exposure (acidic coolants, fertilizer dust), XCMG recommends an additional heavy‑duty powder coat (available as 332107557‑HD). This adds 200 hours of salt spray protection.
Impact resistance: The bracket survived a 50 J impact (simulating a stone strike) without cracking or permanent deflection. The rubber isolators (sold separately) should be replaced at the same time as the bracket to ensure optimal vibration damping.
