The 803412921 Oil Tank Filter Element is a genuine XCMG high‑efficiency filtration component engineered to remove contaminants from hydraulic oil in articulated dump trucks and heavy equipment. This OEM filter element, identified by part number 803412921, features a premium pleated glass-fibre media with high dirt-holding capacity, a robust steel end cap design, and an integral sealing grommet that ensures a perfect fit within the oil tank return line.
Designed for the extreme operating conditions of mining and construction, the 803412921 oil tank filter element delivers exceptional filtration efficiency (β ≥ 1000 for 10 µm), low flow restriction, and long service life, making it an essential replacement part for maintaining hydraulic oil cleanliness, extending component life, and ensuring machine reliability in the most challenging environments.
The 803412921 Oil Tank Filter Element is a critical component that removes particulate contamination from hydraulic oil as it returns to the tank on XCMG articulated dump trucks.
This genuine XCMG element is designed to fit the return-line filter housing in the hydraulic oil tank, providing high‑efficiency filtration to maintain oil cleanliness.
Clean hydraulic oil is essential for component longevity; abrasive particles cause wear in pumps, valves, and actuators, leading to premature failure.
The 803412921 element features a glass‑fibre media with excellent dirt-holding capacity and a beta ratio of 1000 at 10 µm, ensuring superior particle removal.
Its robust steel end caps and integral seals guarantee a reliable fit and prevent bypass, ensuring all fluid passes through the media.
Using genuine XCMG filter elements protects the hydraulic system from contamination‑related failures, reducing downtime and repair costs.
Hydraulic systems are sensitive to contamination; even small particles can cause abrasive wear, clogging, and valve sticking.
The return‑line filter element captures wear debris, ingressed dirt, and sludge, preventing them from re‑entering the pump and components.
The 803412921 element’s high dirt‑holding capacity ensures consistent filtration over long intervals, even in dusty mining environments.
Maintaining oil cleanliness to ISO 4406 code 18/16/13 or better is achievable with this filter, extending oil life and component durability.
Regular element replacement is a cost‑effective measure that prevents expensive hydraulic repairs and unplanned downtime.
The 803412921 filter element is engineered with a high‑surface‑area pleated media pack that maximizes contaminant capacity while maintaining low pressure drop.
The glass‑fibre media is precision‑pleated and supported by a perforated steel inner core that resists collapse under high flow or pressure differential.
The end caps are stamped from zinc‑plated steel and incorporate a nitrile rubber O‑ring that provides a positive seal against the filter housing.
A bypass valve (included in the housing) protects the element from excessive pressure drop, ensuring flow continuity even if the element becomes clogged.
The element is colour‑coded and laser‑marked with the OEM number for easy identification and traceability.
Every element is tested for media integrity, burst strength, and filtration performance before shipment.
The glass‑fibre media used in the 803412921 element offers superior particle capture efficiency compared to cellulose‑based filters.
Its multi‑layer structure provides depth filtration, trapping particles throughout the media thickness, increasing capacity and service life.
The media is treated with a proprietary resin to enhance structural stability and resistance to moisture and oil degradation.
ISO 16889 multi‑pass testing confirms a β ratio ≥ 1000 for particles ≥ 10 µm, indicating a filtration efficiency of over 99.9% at that size.
This performance ensures that the hydraulic oil remains clean enough to protect sensitive components from premature wear.
The 803412921 oil tank filter element is used on XCMG articulated dump trucks, wheel loaders, excavators, and motor graders operating in surface and underground mining.
It is installed in the hydraulic oil tank return line, filtering oil before it re‑enters the reservoir, ensuring continuous cleanliness.
In high‑dust environments, this element provides essential protection by removing silica and other abrasive particles that would otherwise damage hydraulic components.
Its robust construction and high collapse rating make it suitable for applications with high flow rates and pressure spikes.
Regular replacement of this element is a key part of preventive maintenance to ensure hydraulic system reliability.
Every 803412921 filter element is manufactured in an ISO 9001 and ISO 14001 certified facility, with full material traceability.
Incoming media rolls are tested for basis weight, thickness, air permeability, and tensile strength before production.
During pleating, pleat height and spacing are continuously monitored to ensure uniformity and performance.
Completed elements are 100% leak‑tested and inspected for visual defects. A sample from each batch undergoes multi‑pass testing per ISO 16889.
Differential pressure vs. flow curves are verified to ensure the element meets OEM specifications for restriction.
Only elements that pass all tests are released, ensuring consistent quality and performance.
The 803412921 filter element is a direct replacement for the original XCMG oil tank filter on XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, AD45, AD60 articulated dump trucks.
It also fits many XCMG wheel loaders, excavators, and motor graders that use the same return‑line filter housing.
Its dimensions and sealing geometry are precisely matched to the original, ensuring a drop‑in fit without modifications.
For cross‑brand applications, verify the housing diameter, length, and sealing type to ensure compatibility.
Always consult the machine’s parts manual to confirm the correct part number before ordering.
Replacing the 803412921 filter element is a simple task that can be performed with basic hand tools. Ensure the hydraulic system is depressurised.
Remove the filter housing cover (usually bolted or threaded), carefully extract the old element, and clean the housing interior.
Inspect the new element for any damage and ensure the sealing O‑ring is correctly positioned. Insert the element into the housing.
Reinstall the cover, tighten the fasteners to the recommended torque (25‑30 N·m), and start the engine to check for leaks.
Replace the element at the recommended interval or when the differential pressure indicator shows clogging.
Keep a spare element on hand to minimise downtime during scheduled maintenance or unexpected clogging.
The 803412921 filter element complies with ISO 16889, the international standard for hydraulic filter performance evaluation.
It is manufactured in accordance with ISO 9001 quality management and ISO 14001 environmental standards.
The materials used are RoHS compliant and free from hazardous substances.
Using genuine XCMG filter elements ensures compliance with original equipment performance and warranty requirements.
Always follow the manufacturer’s guidelines for filter change intervals to maintain hydraulic system safety and efficiency.
Aftermarket filter elements often use inferior media, poor pleating, or improper seals that allow unfiltered oil to bypass, damaging components.
