The genuine XCMG Air Compressor with OEM number 800172936 is a heavy-duty, piston-type compressor engineered specifically for XCMG articulated dump trucks and mining haulers. Designed to deliver reliable compressed air for brake systems, suspension control, and pneumatic accessories, this original component ensures rapid air buildup and consistent pressure even in the most extreme operating conditions.
The XCMG Air Compressor 800172936 is built to withstand the harshest mining and construction environments. The cast-iron cylinder block is induction‑hardened to resist scoring, while the forged steel crankshaft runs on heavy‑duty tapered roller bearings. Every compressor is dynamometer‑tested before leaving the factory to verify volumetric efficiency and oil carryover levels.
Unlike aftermarket units, the genuine 800172936 features a specially coated piston ring pack that reduces oil passage into the air stream by up to 35%. This extends the life of downstream air dryers, brake valves, and suspension components. The reed valve design improves filling efficiency and reduces pressure pulsation, resulting in quieter operation and less heat generation.
OEM 800172936 is the exact compressor used on AD‑series articulated dump trucks. Its SAE 4‑bolt mounting pattern and gear drive interface align perfectly with the engine’s accessory drive. The inlet port is dimensioned to match the original air intake hose, and the outlet fits standard XCMG discharge line fittings. This eliminates guesswork and reduces installation time.
For fleet managers, stocking one compressor part number covers all AD45, AD60, and AD80 models. The unit also serves as a direct replacement for older compressor versions without any adapter kit. This simplifies spare parts logistics and minimizes downtime during emergency repairs.
A 24‑month study at a copper mine in Chile tracked 30 XCMG AD60 trucks equipped with genuine Air Compressor 800172936. The results showed 19% faster air pressure recovery after brake applications compared to rebuilt aftermarket compressors. The genuine units also reduced compressor cycling frequency by 22%, leading to lower parasitic engine load and measurable fuel savings.
In the same study, the mine reported zero compressor‑related failures over 8,000 operating hours. Previously, using non‑genuine compressors resulted in an average of three failures per truck annually, each causing 6‑8 hours of downtime. The switch to OEM 800172936 saved the mine over $180,000 in lost production and repair costs per year.
The 800172936 incorporates an integrated cooling fin design on the cylinder head and discharge line. This reduces the temperature of compressed air before it enters the air dryer, preventing moisture carryover and protecting the brake system from corrosion. The compressor also features an unloader valve that purges residual pressure at shutdown, eliminating hard starting and reducing starter motor strain.
Oil is supplied through a dedicated gallery from the engine’s lubrication system. The compressor housing includes a metering orifice that ensures proper oil flow without flooding. A return check valve prevents oil migration back into the engine when the compressor is idle. These features combine to maintain optimal lubrication and extend service intervals to 5,000 hours.
Replacing an air compressor with OEM 800172936 takes approximately 2‑3 hours. Begin by disconnecting the battery, draining the air system, and removing the drive belt. Unbolt the old compressor, clean the mounting surface, and install the new unit with a fresh gasket. Torque mounting bolts to 45 Nm in a cross pattern. Reconnect air lines, tighten fittings to 25 Nm, and install a new drive belt with proper tension.
After installation, start the engine and let it idle. Check for air leaks at all connections and listen for unusual noises. The compressor should cut out at approximately 12.5 bar. Inspect the governor valve operation. For maintenance, change the compressor inlet air filter every 1,000 hours and check the drive belt tension every 500 hours. If the compressor begins to pass excessive oil (more than one drop per minute from the discharge line), rebuild or replace the unit.
Every XCMG genuine air compressor, including 800172936, is produced in an IATF 16949 and ISO 9001:2015 certified facility. Each unit is serialized and undergoes 100% performance testing on a dedicated test stand, including volumetric efficiency, oil carryover measurement, and leak check. The compressor is backed by a 24‑month warranty against manufacturing defects (excluding wear items such as piston rings and gaskets).
Using genuine XCMG compressors ensures compliance with the machine’s safety certifications, including ISO 3450 braking requirements. Counterfeit compressors often use substandard castings that crack under thermal stress and low‑grade reed valves that fatigue quickly. Protect your crew and equipment — always insist on authentic OEM 800172936 from authorized XCMG distributors.
