The genuine XCMG Bracket with OEM number 800172815 is a heavy-duty mounting component engineered for XCMG articulated dump trucks, wheel loaders, and off-highway equipment. This bracket securely supports critical assemblies such as engine alternators, air compressors, power steering pumps, hydraulic valve blocks, and coolant filter heads. Manufactured from high-strength ductile iron or heavy-gauge steel with E-coat corrosion protection, the XCMG 800172815 bracket provides precise alignment, vibration damping, and long-term reliability in extreme mining and construction environments.
The XCMG Bracket 800172815 is a key structural link between heavy engine accessories and the engine block or chassis frame. A properly designed bracket prevents component vibration, belt misalignment, and premature bearing failure. Genuine XCMG brackets are engineered to exact original dimensions and load capacity, ensuring that alternators, compressors, and pumps remain securely fastened even under the severe vibration of mining haul roads.
On AD60 and AD80 articulated dump trucks, the 800172815 bracket is commonly used for the heavy-duty alternator mount and power steering pump. Field data from Australian mines shows that genuine XCMG brackets reduce component replacement frequency by 40% compared to aftermarket copies, thanks to superior material strength and casting integrity.
The 800172815 bracket is cast from GGG50 ductile iron or fabricated from high-strength steel. Nodular graphite in the iron provides excellent fatigue resistance and impact toughness, essential for components that experience cyclic bending loads. The part is heat‑treated to relieve residual stresses and normalized for dimensional stability.
The E‑coat cathodic epoxy coating covers all surfaces, internal and external, preventing rust from forming in threaded holes or crevices. This coating is baked at 200°C for full cross‑linking, ensuring resistance to stone chipping, coolant spills, and road salt. The bracket is also compatible with high‑pressure washdowns (IP6K9K).
The XCMG bracket 800172815 is a direct OEM replacement for original part numbers 800172815A, 860124580, and 860298754. It is designed to match the exact mounting boss geometry and bolt pattern of the Cummins QSM11 or Deutz TCD 2013 engine front cover. Critical dimensions such as hole spacing and offset are CNC‑machined to ±0.1 mm after casting.
For AD100 trucks with twin alternators, a reinforced version (suffix “-HD”) is available with additional gussets and larger bolt diameters. Always verify the engine serial number before ordering, as different alternator footprints require specific bracket offsets. XCMG provides a clear dimensional drawing in the parts catalog.
To replace a damaged bracket, first remove the component it supports (alternator, compressor, etc.). Disconnect any belt or hose attachments. Unbolt the bracket using the appropriate socket (typically 13mm, 15mm, or 18mm). Clean the engine block or chassis mounting surface. Inspect the old bracket for cracks – if cracked, check the mating surface for damage.
Install the new XCMG 800172815 bracket using new grade‑10.9 bolts and washers (included in the kit). Apply a small amount of medium-strength thread locker to the bolts. Torque to the engine manual specification (typically 45–65 Nm for M10 bolts, 80–100 Nm for M12). Reinstall the accessory, belt, and hoses. Start the engine and check for belt alignment and any unusual vibration.
After the first 10 hours of operation, re‑torque the bracket bolts. Inspect the bracket during every oil change for signs of cracking, especially near the mounting holes. Replace the bracket immediately if any crack is detected. Proactive replacement is recommended every 5,000 hours or whenever the attached accessory is replaced.
Counterfeit brackets sold as 800172815 often use gray cast iron instead of ductile iron. Gray iron is brittle and can crack without warning, causing the attached accessory to drop or vibrate excessively. Symptoms include belt misalignment, accessory bracket fracture, or a sudden failure of the alternator mount. Genuine XCMG brackets have a matte E‑coat finish, a laser‑etched part number, and a holographic label on the packaging.
Another common issue is incorrect hole spacing. Aftermarket brackets may have poorly drilled holes, leading to bolt binding or misalignment. Always test‑fit the bracket without bolts first. Genuine XCMG brackets have perfectly aligned machined bores and will slide onto the studs or bolts with minimal effort.
Corrosion: Non‑genuine brackets may have only a thin paint coating that peels off, leading to rust that weakens the casting. Genuine XCMG E‑coat penetrates pores and resists chipping. The bracket should have a uniform dark gray matte finish, not glossy black paint.
A broken alternator bracket can allow the alternator to swing into the belt, shredding the belt and damaging the water pump and fan. Repair costs can exceed $1,000 for the alternator, belt, and pulley. Replacing a cracked bracket with a genuine XCMG 800172815 bracket (approx. $65) is a small investment that prevents catastrophic damage.
Preventive maintenance: During daily inspections, look for rust lines around bolt holes (which may indicate cracks) or any visible deformation of the bracket. Also, check belt alignment – if the belt is wearing on one edge, the bracket may be bent. Replace the bracket immediately if any crack is found, no matter how small.
Payback analysis: A genuine bracket costs ~$65. If it prevents one alternator failure ($500) and a belt breakdown ($200), plus downtime ($500), the savings exceed $1,100. For fleets, proactively replacing brackets every 5,000 hours eliminates component drop‑off failures.
Every XCMG Bracket 800172815 is manufactured in an IATF 16949‑certified foundry or fabrication facility. Each casting is 100% inspected by magnetic particle testing (MT) to detect surface cracks. Random samples are tested for tensile strength, hardness, and microstructure (nodularity >80%). The E‑coat thickness is measured at six points per bracket. XCMG provides a 24‑month warranty against casting defects or breakage under normal use.
Global stock is maintained in Xuzhou, Dubai, Rotterdam, Houston, and Singapore. Emergency orders ship within 24 hours. Bulk packs of 5 brackets (part number 800172815‑B5) are available for fleet customers at a 12% discount. Each bracket includes new mounting bolts, washers, and a tube of anti‑seize compound.
To verify authenticity, scan the QR code on the packaging – it links to the material certificate, MT report, and E‑coat thickness record. Always insist on genuine XCMG 800172815; counterfeit brackets have been known to fracture after only a few hundred hours of operation, causing severe accessory damage.
XCMG engineers tested the 800172815 bracket under extreme conditions: 5,000 hours of engine dynamometer operation with simulated haul road vibration, 1,000 thermal cycles from -40°C to +130°C, and 1,000 hours of salt spray. The bracket showed no crack propagation, no bolt hole elongation, and the E‑coat remained intact. The ductile iron retained >90% of original tensile strength.
For applications with very high belt loads (e.g., heavy‑duty alternator plus fan), XCMG offers a reinforced version with thicker ribs and an integrated support gusset (suffix “-HD”). This version is recommended for AD100 trucks or any machine with a belt‑driven air compressor.
The bracket’s design includes stress‑relieving fillets at all corners and tapered ribs to distribute loads evenly. Finite element analysis (FEA) shows a safety factor of 5× the expected maximum service load, ensuring the bracket will not fail under normal operation.
