The XCMG Oil-Water Filter Element with OEM number 841145216 is a high-efficiency fuel water separator and diesel primary filter element specifically engineered for XCMG articulated dump trucks. This spin-on filter element removes solid contaminants and emulsified water from diesel fuel, protecting high-pressure common rail injection systems from corrosion, injector clogging, and premature wear in extreme off-road conditions.
Manufactured using multi-layer synthetic fiber media with a water-coalescing layer, the filter element 841145216 achieves ≥ 98.7% filtration efficiency at 4 microns and ≥ 95% water separation efficiency per ISO 16332. The coalescing technology converts microscopic water droplets into larger drops that settle into the integrated sediment bowl, preventing water from reaching sensitive fuel system components.
This OEM filter element is designed for Cummins QSM11, QSX15, Mercedes-Benz OM460, and Deutz TCD engines commonly installed in XCMG AD-series trucks. Direct interchangeability with original equipment ensures seamless replacement during routine maintenance, minimizing equipment downtime and preserving engine warranty coverage.
Each filter element 841145216 is manufactured under IATF 16949 quality management systems, with 100% leak testing and media integrity verification. Using genuine XCMG filtration components prevents fuel system damage caused by counterfeit filters that compromise media structure or omit the water-separating layer entirely.
The 841145216 filter element employs a three-stage filtration process: first, a coarse pre-filter layer traps large particles (25–50 microns). Second, a hydrophobic coalescing media forces emulsified water droplets to combine and grow. Third, a high-efficiency synthetic barrier captures remaining solids down to 4 microns absolute while allowing only clean, dry diesel to exit the filter. This design is critical for common rail injectors that have clearances measured in microns.
Water separation efficiency exceeds 95% when tested with emulsified water concentrations typical of condensate contamination. Field data from AD45 and AD60 trucks shows that using the genuine 841145216 filter reduces water-related injector failures by 85% compared to non-genuine or expired filters. The filter also maintains high flow capacity (200 L/h) even when partially loaded, preventing fuel starvation during high-demand operations.
An optional water-in-fuel (WIF) sensor port at the bottom of the sediment bowl allows real-time monitoring of water accumulation. When water reaches the sensor tip, the dash light illuminates, alerting the operator to drain the bowl. This proactive alert prevents water from being drawn into the injection pump and damaging precision components.
The filter media in 841145216 consists of multiple layers of resin-impregnated synthetic fibers. The outer depth layer has increasing pore density, allowing it to hold up to 50 grams of solid contaminants without excessive pressure drop. The coalescing layer is treated with a proprietary fluoropolymer that repels water while permitting diesel flow. The final barrier layer is a calibrated nonwoven fabric with a pore size distribution verified by bubble-point testing.
All media pleats are thermally bonded to a perforated steel center tube, preventing media migration and ensuring uniform flow distribution. The end caps are made from high-temperature nylon, ultrasonically welded to the media pack. The spin-on canister is manufactured from zinc-coated steel with a durable epoxy paint finish that resists fuel splash, moisture, and corrosion.
The integrated O-ring seal is made from fluorocarbon rubber (FKM), providing superior compatibility with biodiesel blends (B20 and higher) and resistance to swelling or hardening over time. Unlike nitrile seals that degrade in biodiesel, the FKM seal maintains its elasticity for the full 500‑hour service interval.
The 841145216 oil-water filter element is the OEM specified primary fuel filter for XCMG AD45, AD60, AD80, and AD100 articulated dump trucks. It mounts on the filter head with M22 × 1.5 thread pitch and a 93 mm canister diameter. It directly replaces XCMG part numbers 841145214, 841145215, and is cross‑compatible with aftermarket heads using the same thread and sealing profile.
Engine platforms that use this filter include Cummins QSM11 (Tier 3/4), QSX15, Mercedes-Benz OM460LA, and Deutz TCD 2013. The filter is also used on XCMG XE370/470 excavators and LW800/900 wheel loaders sharing the same fuel system architecture. Always verify the filter head thread and canister size before ordering; a mismatched filter can leak or fail to seal.
For trucks equipped with a secondary inline fuel filter (2‑micron absolute), the 841145216 serves as the primary water separator and 10‑micron pre‑filter. The combination ensures that the fuel reaching the injection pump meets ISO 4406 cleanliness codes of 18/16/13, which is required for common rail injector life exceeding 10,000 hours.
Symptoms of a failing or contaminated filter include: loss of engine power under load (fuel starvation), rough idle, white/black smoke from exhaust (water in combustion), frequent DPF regeneration due to poor combustion, and water-in-fuel warning light illumination. If ignored, water can reach the high-pressure pump, causing plunger seizure and metal debris circulation throughout the injection system.
Replacing a seized injection pump on a Cummins QSM11 costs over $4,000 in parts plus 8–10 hours of labor. Injector replacement for all six cylinders exceeds $6,000. The genuine 841145216 filter element is priced under $30, making preventive replacement every 500 hours one of the most cost-effective maintenance actions.
Counterfeit filters often use low-grade paper media that disintegrates after 100–200 hours, sending debris directly to the injectors. Some fakes omit the coalescing layer entirely, resulting in water separation efficiency below 30%. Always purchase from authorized XCMG dealers and verify the holographic seal on the box.
To install the 841145216 filter element, park the truck on level ground, stop the engine, and allow it to cool. Place a drain pan under the filter. Clean the filter head area with compressed air to prevent dirt ingress. Use a strap wrench to unscrew the old filter counterclockwise. Dispose of the old filter properly.
Apply a thin film of clean diesel fuel to the new O-ring. Hand-screw the filter onto the head until the gasket contacts, then tighten an additional ¾ to 1 turn. Do not use a wrench, as over-torquing can distort the seal. Prime the fuel system using the hand primer pump until resistance is felt. Start the engine and check for leaks.
Inspect the sediment bowl daily for water accumulation. Water appears as a distinct layer at the bottom. If the bowl is more than 1/3 full, open the drain valve and allow water to flow until clean diesel appears. Replace the filter every 500 hours or at every second oil change, whichever comes first. Keep spare filters on the service truck to avoid downtime.
Selecting the authentic 841145216 oil-water filter element ensures certified filtration efficiency, proper water separation performance, and full warranty protection for your engine. Unlike aftermarket imitations, genuine XCMG components maintain the fuel cleanliness levels required for common rail injectors, protecting your investment and maximizing uptime over the equipment’s service life.
