WEICHAI Spare Parts 61500080078 Fuel coarse filter

Weichai part number 61500080078 is a coarse diesel filter (also known as a fuel-water separator element) widely used in heavy-duty trucks. It is primarily installed on trucks equipped with Weichai (WP10/WP12) or Sinotruk (WD615) engines—such as those from brands like Howo, Shacman, and Auman. Serving as the first line of defense in the fuel system, it is designed to filter out large particulate impurities and separate water from the diesel fuel, thereby protecting downstream precision fuel injectors from wear and corrosion.

Product Description

Ordering & Shipping Information

Spin-on Design: Features a standard cylindrical, integrated steel housing and a standard threaded connection (typically 1-14 UNS). Maintenance technicians or truck drivers can quickly unscrew and replace the unit using a standard filter wrench, significantly reducing downtime for routine servicing and on-the-road maintenance.

Dual-Stage Water Separation: The internal filter media is treated with a special hydrophobic resin coating. It efficiently coalesces microscopic free water and emulsified water droplets found in diesel fuel into larger droplets, allowing them to settle at the bottom of the filter. Given the high sensitivity of high-pressure common-rail systems to water, this design effectively prevents corrosion or seizure (due to freezing) of precision fuel injectors and high-pressure fuel pumps.

Heavy-Duty Steel Shell: The housing is stamped from high-strength, cold-rolled steel. During long-haul, heavy-load operations, fuel lines experience continuous pressure fluctuations. The reinforced housing withstands higher burst pressures and effectively resists physical impacts from road debris—such as flying stones, sand, and grit—preventing fuel leaks.

Integrated Sensor Port: The bottom of the filter features a standard opening and a sealing groove designed to accommodate a transparent water collection bowl. This allows drivers to visually inspect accumulated water and contaminants while also enabling the direct installation of a water-level sensor. When accumulated water reaches a critical level, the sensor communicates with the vehicle's ECU to trigger a dashboard warning, prompting the driver to drain the water.

High-Density Pleated Media: Utilizes a unique, densely pleated, and cured filter medium. This design maximizes the physical filtration surface area within a compact volume. It consistently captures the vast majority of large contaminants (such as silt and metal filings) from the fuel stream without impeding flow rates, thereby extending the service life of downstream fine-filtration components.
