OEM 803597981 The XCMG Desiccator And Bracket Assembly (803597981) is a genuine OEM combined desiccant air dryer and mounting bracket engineered to remove moisture and contaminants from the compressed air system of XCMG articulated dump trucks. This precision‑built assembly, identified by part number 803597981, delivers reliable air drying, efficient filtration, and robust mounting support in the most demanding mining, quarrying, and heavy construction environments worldwide.
Manufactured from high‑strength aluminium with a corrosion‑resistant coating, the 803597981 desiccator and bracket assembly features a self‑regenerating desiccant bed, an integrated coalescing filter, and a sturdy mounting bracket that guarantees a perfect, drop‑in fit without modification. Its design ensures that the air supply to the brake system, suspension, and other pneumatic controls remains clean and dry, preventing freeze‑up and corrosion.
The 803597981 assembly incorporates a specially engineered purge system that efficiently regenerates the desiccant, extending service intervals and maintaining consistent dew‑point performance. This makes it an essential component for preserving brake system reliability, preventing valve sticking, and ensuring overall machine uptime in your ADT fleet.
The 803597981 Desiccator And Bracket Assembly combines a high‑efficiency desiccant dryer with a rugged mounting bracket, providing a complete solution for removing moisture, oil, and particulate contaminants from the compressed air stream. This ensures that critical pneumatic components — brakes, suspension, and clutch controls — operate reliably without freeze‑up or corrosion.
Its self‑regenerating desiccant bed uses a small purge flow to continuously dry the media, maintaining a consistent pressure dew point of -40°C even in high‑humidity conditions. This extends the life of valves, cylinders, and seals, and reduces the need for frequent system draining.
The integrated coalescing filter removes oil aerosols and solid particles down to 0.01 microns, protecting sensitive components from abrasive wear and chemical attack. The entire assembly is housed in a corrosion‑resistant aluminium body that withstands the harshest under‑chassis conditions.
The heavy‑duty steel bracket is zinc‑plated and equipped with rubber isolators to dampen vibration, ensuring that the dryer remains securely attached and free from fatigue cracks. Its precise mounting hole pattern matches the original factory locations, allowing a direct bolt‑on installation.
In demanding applications such as open‑pit mines, aggregate quarries, and heavy construction sites, the 803597981 delivers reliable, clean air that keeps your ADT’s pneumatic systems operating at peak efficiency, reducing unscheduled maintenance and avoiding costly downtime.
Its robust construction and corrosion‑resistant materials ensure a long service life, with desiccant replacement intervals typically exceeding 10,000 operating hours.
The 803597981 assembly utilises a proprietary blend of activated alumina and molecular sieve desiccant that provides high water adsorption capacity and resistance to oil degradation. The desiccant bed is designed to promote uniform flow and prevent channelling, maximising drying efficiency.
The coalescing filter element features a multi‑layer borosilicate fibre matrix that captures oil droplets and solid particles with 99.9% efficiency at 0.01 µm, ensuring that downstream air is virtually oil‑free and clean.
The purge system is calibrated to provide just enough air to regenerate the desiccant without wasting excessive compressed air, balancing energy efficiency with drying performance.
Each assembly is pressure‑tested and leak‑checked at the factory, and the desiccant is pre‑conditioned to ensure immediate full performance upon installation.
The bracket is designed with slotted holes to allow minor adjustment during installation, accommodating frame variations without compromising alignment.
After production, each unit undergoes a 100% functional test to verify dew‑point performance and flow capacity, as well as a vibration test to validate bracket durability.
Articulated dump trucks depend on clean, dry compressed air for reliable braking, suspension levelling, and clutch actuation. Moisture in the air system can cause freeze‑up in cold climates, corrosion of internal components, and sticking of valves, leading to dangerous loss of braking performance.
The 803597981 desiccator assembly actively removes water vapour and contaminants, ensuring that the air delivered to the brake chambers, air springs, and other actuators is always at the required dew point.
A degraded or undersized dryer can lead to moisture carryover, which causes condensation in brake lines, accelerated wear of seals, and intermittent brake response — risks that are eliminated by using genuine XCMG components.
Field data from mining operations shows that ADTs equipped with genuine XCMG desiccator assemblies experience 50% fewer air system freeze‑ups and a 30% reduction in valve and cylinder replacements, directly improving safety and uptime.
The assembly’s consistent drying performance ensures that the air dryer protection valve and other safety devices function correctly, maintaining compliance with regulatory standards.
Regular inspection of the desiccant condition and filter element is recommended; replacement should be performed according to the maintenance schedule or when the dew‑point sensor indicates a rise.
The 803597981 desiccator and bracket assembly is constructed from premium materials that provide an exceptional combination of strength, corrosion resistance, and thermal stability, ensuring reliable performance under the most severe operating conditions.
The aluminium housing is anodised to resist pitting and chemical attack from road salts, oils, and cleaning agents, maintaining its structural integrity over many years.
The desiccant material is selected for its high crushing strength and low dust generation, preventing contamination of downstream components.
The bracket is fabricated from high‑strength steel and zinc‑plated to prevent rust, with rubber grommets that isolate the dryer from chassis vibration.
With proper maintenance, the 803597981 assembly can provide reliable service for the entire lifespan of the ADT, protecting the pneumatic system from moisture‑related damage.
The combination of high‑quality materials, precision manufacturing, and robust design makes this assembly ideal for the most demanding off‑highway applications.

The 803597981 desiccator and bracket assembly is designed for straightforward installation using standard workshop tools, minimising downtime and labour costs during routine servicing or component replacement.
Before installation, ensure the air system is depressurised and clean the mounting area on the chassis. Remove the old dryer assembly and inspect the air lines for any signs of contamination.
Position the new bracket on the frame, aligning the holes with the existing mounting points. Secure the bracket using the supplied bolts and torque to the specified value.
Attach the dryer to the bracket, ensuring the rubber isolators are properly seated. Connect the inlet and outlet air lines, using new O‑rings or seals if required, and tighten the fittings to the recommended torque.
After installation, pressurise the system and check for leaks using soapy water or a leak detector. Verify that the dryer’s purge operation is audible and that the dew‑point indicator (if equipped) shows normal drying.
Periodic inspection of the desiccant and filter element, along with replacement at the recommended interval, will help maintain optimal air quality and system performance.
Investing in the genuine 803597981 desiccator and bracket assembly delivers significant long‑term savings by preventing air system corrosion, reducing wear on valves and actuators, and avoiding costly downtime that can result from moisture‑related failures.
A single brake valve failure due to contamination can cost over $1,500 in parts and labour, plus lost production — a risk that is virtually eliminated with OEM‑quality components.
Over a typical 15,000‑hour service life, an ADT’s air system processes millions of litres of air. The 803597981’s efficient drying and filtration ensure that contaminants are removed before they can cause damage.
