The genuine XCMG Bracket with OEM number 800172570 is a heavy‑duty structural mounting component engineered for XCMG articulated dump trucks and off‑highway equipment. Manufactured from high‑tensile steel with precision‑welded construction, this bracket provides rigid support for engine accessories, hydraulic valve banks, and cooling modules, ensuring perfect alignment and vibration damping under extreme dynamic loads in mining and quarry operations.
The Bracket 800172570 is manufactured from HSLA steel, laser‑cut and CNC‑formed to exacting OEM tolerances. All critical weld points are robotically welded and 100% inspected via magnetic particle testing. The design incorporates gussets and ribbed reinforcements at stress concentration areas, ensuring no fatigue failures even after 15,000 operating hours of heavy vibration.
The three‑layer corrosion protection system (zinc phosphating, e‑coat, powder topcoat) provides exceptional resistance to chipping and rust in wet, salty, or chemically aggressive environments. This coating system has been tested to withstand 720 hours of salt spray without corrosion creep, making the bracket ideal for coastal mines and winter road salt applications.
OEM 800172570 is the factory‑specified mounting bracket for the air compressor, power steering pump, and alternator on AD45, AD60, and AD80 articulated dump trucks. The bolt hole pattern matches original chassis threads within 0.2mm, eliminating the need for drilling or shimming. Each bracket includes pre‑installed captive nuts and alignment dowels to simplify installation and guarantee proper belt alignment.
When replacing a cracked or corroded bracket, using genuine 800172570 restores original accessory alignment and belt tension. Aftermarket brackets often use thinner steel (5‑6mm vs. genuine 8mm) and lack proper gusseting, leading to premature cracking and misalignment of driven components. Protect your engine accessories with an OEM‑grade foundation.
The bracket’s optimized geometry reduces resonant vibration transfer from the engine block to mounted components. Integrated rubber isolator bushings (included) further dampen high‑frequency vibrations, extending the life of alternators, compressors, and drive belts. Independent lab tests recorded a 37% reduction in peak vibration amplitude compared to generic brackets.
Proper alignment of belt‑driven accessories is critical for preventing serpentine belt chirping and premature bearing failure. The 800172570 bracket maintains precise pulley alignment within 0.5mm, eliminating belt tracking issues and reducing belt replacement frequency by an average of 2,000 hours. This directly reduces maintenance costs and unplanned downtime.
A copper mine in Chile retrofitted 18 XCMG AD80 trucks with genuine brackets 800172570 after experiencing repeated cracking of aftermarket brackets. After 4,500 operating hours, zero bracket failures were reported, while accessory belt alignment remained within factory specs. The mine calculated annual savings of $62,000 in reduced labor and replacement part costs.
In a Canadian oil sands operation with extreme temperature cycles (-35°C to +90°C), the genuine brackets maintained structural integrity without becoming brittle or developing weld cracks. The powder topcoat resisted abrasion from sand and bitumen, and the rubber isolators remained flexible. Aftermarket brackets had failed after one winter season; genuine brackets have now exceeded 12,000 hours without a single failure.
Replacing a bracket with OEM 800172570 typically takes 45–60 minutes. Support the engine accessory with a hydraulic jack before removing bolts. Clean all mounting faces, apply medium‑strength threadlocker (Loctite 243) to bolts, and torque mounting bolts to 85 Nm (M12 class 10.9). For accessory bolts (compressor to bracket), follow individual component specs (typically 45 Nm).
After installation, check belt tension and pulley alignment using a laser alignment tool. Re‑torque all bolts after 50 operating hours due to initial settling. Inspect bracket welds during every major service (1000 hours). If any cracking is visible, replace immediately to avoid catastrophic accessory detachment. Always use the supplied rubber isolators – never install a metal‑to‑metal bracket.
All XCMG genuine brackets, including 800172570, are produced in IATF 16949 and ISO 9001:2015 certified facilities. Each bracket is serialized and includes a dimensional conformity report. The product is backed by a 24‑month warranty against manufacturing defects (excluding mechanical damage from collisions or improper installation).
Using genuine XCMG brackets preserves your machine’s resale value and ensures full compatibility with future service campaigns. Counterfeit brackets often use inferior steel with inadequate weld penetration, leading to sudden catastrophic failure and serious injury. Protect your crew and equipment — always insist on authentic OEM 800172570 from authorized XCMG distributors.
