The genuine XCMG Refrigerant Compressor with OEM number 800172862 is a heavy-duty air conditioning compressor engineered for XCMG articulated dump trucks and large construction equipment. This compressor delivers reliable cab cooling in extreme ambient temperatures, using a swashplate design and R134a refrigerant. The OEM 800172862 compressor ensures operator comfort and prevents heat stress during long shifts in mining or desert environments.
The XCMG Refrigerant Compressor 800172862 is specifically calibrated for the thermal loads of articulated dump truck cabs, which feature large glass areas and operate in direct sunlight. With a cooling capacity of 10.5 kW, it can lower cabin temperature from 50°C to 22°C within 8 minutes. The swashplate design delivers smooth torque delivery and low vibration, reducing stress on the drive belt and engine front end.
The compressor is driven by the engine’s serpentine belt via a 6PK pulley. Its electromagnetic clutch engages only when cooling is demanded, saving fuel. An integrated low-pressure cutoff prevents the compressor from running when refrigerant charge is low, avoiding seizure due to oil starvation. OEM 800172862 compressors are factory-tested for refrigerant leak integrity and clutch engagement cycle life exceeding 500,000 cycles.
Inside the compressor, nine double-ended pistons are driven by a angled swashplate mounted on a wobble plate. This design provides excellent volumetric efficiency (over 92%) and allows the compressor to handle high suction pressures without slugging. The pistons feature PTFE-coated skirts for low friction, and the cylinder bores are honed to a mirror finish. All bearings are high-speed C3 clearance, lubricated by refrigerant oil mist.
The housing is die-cast from A380 aluminum and treated with a chromate conversion coating to resist corrosion from road salt or chemical sprays. The rear head incorporates a dual-pressure relief valve that opens at 3.5 MPa to protect the system. XCMG’s 800172862 compressor is designed for a 10,000-hour service life under normal cab usage (2,000 engine hours per year).
The 800172862 compressor mounts directly to the OEM bracket on AD45, AD60, AD80, and AD100 trucks. It uses four M8 bolts on 102 mm centers and aligns with the belt path using a factory-installed spacer. The electrical connector is a two-pin Deutsch DT04-2P (pin 1 = clutch ground, pin 2 = clutch power, 24V). Replacement requires no adapter plates or harness modifications.
Beyond dump trucks, this compressor is used on XE490 excavators, LW900K loaders, and some GR road graders that share the same HVAC system. However, always verify the clutch voltage (12V vs 24V). AD-series uses 24V; if retrofitting to a 12V machine, a different clutch coil is required. The genuine XCMG part is clearly marked with a red 24V sticker on the clutch housing.
Before installing the Refrigerant Compressor 800172862, recover the remaining R134a using certified equipment. Replace the receiver-drier and expansion valve as a set. Flush the evaporator and condenser if contamination is suspected. Mount the new compressor and torque the bolts to 25 Nm. Connect the discharge and suction lines with new O-rings lubricated with PAG oil.
Evacuate the system for at least 45 minutes to remove moisture. Charge with the specified amount of R134a (typically 1.2–1.5 kg for AD trucks) and the correct PAG 46 oil (total system oil capacity 250 ml, the compressor comes with 150 ml, add 100 ml to the system). Start the engine and engage the clutch; high-side pressure should be 1.2–1.8 MPa at 2,000 RPM. Check for temperature drop at vents (should be ≤ 8°C).
Common failure indicators for the 800172862 compressor include clutch slippage (audible screech when engaged), insufficient cooling, or metal debris in the refrigerant lines. A seized compressor can snap the serpentine belt, leaving the truck without alternator charging or power steering – a critical safety issue. Many counterfeit compressors fail due to undersized clutch bearings that overheat within 500 hours.
Genuine XCMG compressors feature a thermal protector that disengages the clutch if internal temperature exceeds 150°C. This prevents catastrophic failure. Replacing a blown compressor costs around $1,200 in parts plus $500 in labor and refrigerant, whereas a preventative replacement (every 6,000 hours) costs only the part. Invest in OEM quality for lowest lifecycle cost.
Authentic XCMG 800172862 compressors have the part number laser-etched on the rear head, a holographic certification label on the carton, and a date code stamped on the clutch plate. The clutch friction surface is machined, not painted. Counterfeit units often use a painted clutch that glazes quickly, leading to slipping. Also, genuine compressors are filled with high-quality Nippon Denso or Sanden-equivalent internal parts, not generic Chinese clones.
Another red flag is insufficient oil charge. Genuine compressors contain exactly 150 ml of PAG 46; counterfeits often have less or the wrong oil viscosity, causing wear within 100 hours. Always purchase from authorized XCMG distributors or the official online store. Protect your cab climate system – insist on genuine XCMG.
The XCMG 800172862 compressor is designed for R134a refrigerant, which has zero ozone depletion potential (ODP). The compressor’s internal seals are made of HNBR, which resists permeation, reducing annual refrigerant leakage to less than 5 grams. Additionally, the variable displacement version (optional) adjusts piston stroke to match cooling demand, cutting parasitic load by up to 30% compared to fixed-displacement units.
For fleet operators, upgrading to a genuine XCMG compressor can reduce fuel consumption by approximately 0.5–1.0 liter per operating hour (when AC is used 50% of the time). Over a 5,000-hour lifecycle, that saves 2,500–5,000 liters of diesel. The compressor is also 95% recyclable at end of life.
Every genuine XCMG Refrigerant Compressor 800172862 comes with a 24-month unlimited-hour warranty against manufacturing defects. XCMG maintains a global network of service centers that can perform AC diagnostics and compressor replacement. The compressor is backed by ISO 9001:2015 and IATF 16949 certified production, ensuring consistent quality.
For warranty claims, the original purchase invoice and the serial number on the compressor must be provided. XCMG recommends using only genuine accessories (receiver-drier, expansion valve, O-rings) to maintain warranty validity. Keep your operators cool and productive with XCMG original AC components.
