The 860140474 Oil-Water Separator Element is a genuine XCMG fuel filtration component designed for GR series motor graders. This high-efficiency filter element removes water and particulate contamination from diesel fuel, protecting the fuel injection system from damage. The 860140474 oil-water separator element features a multi-layer cellulose/synthetic media with a water-repellent coating and a sediment bowl interface. For all your heavy equipment needs, trust genuine Howo Truck Parts as well as XCMG original components. It is a critical component for maintaining clean, water-free fuel and preventing injector corrosion on GR series graders.
The 860140474 Oil-Water Separator Element is manufactured to ISO 4020 standards, with a filtration efficiency of 98% at 5 microns and 99.9% water separation efficiency. The element has an outer diameter of 85 mm, inner diameter of 45 mm, and a height of 125 mm. It features a nitrile rubber gasket and a center tube for structural rigidity. As a genuine XCMG part, it matches the original filtration area, bypass valve setting, and sealing geometry exactly.
Engineered for extreme durability, the 860140474 Oil-Water Separator Element has a service life of 500 operating hours under normal fuel conditions. The media is treated with a hydrophobic resin that repels water while allowing fuel to pass freely. Each element is 100% inspected for media integrity and seal fit. Using genuine XCMG elements prevents water ingress, injector nozzle erosion, and fuel system corrosion that can lead to costly engine repairs.

Genuine XCMG oil-water separator elements are essential for maintaining the health of modern common-rail diesel engines. Their advanced media traps free and emulsified water, preventing injector tip erosion, pump seizure, and combustion chamber damage. Using OEM filters guarantees proper fit and protection.
Aftermarket fuel filters often use basic media that cannot separate water effectively or have poor particle retention. The genuine 860140474 Oil-Water Separator Element from XCMG features a multi-layer composite media with a water-repellent outer layer and a fine cellulose inner layer. Independent tests show that OEM elements remove 99.9% of water and 98% of 5-micron particles, while generic filters may achieve only 60% water separation. This protection prevents costly fuel system repairs that can exceed $10,000.
Each 860140474 Oil-Water Separator Element is traceable to its production batch, with records of media batch, burst strength, and water separation efficiency. The element is printed with the XCMG part number and date code for easy identification. XCMG’s quality control includes 100% visual inspection and random sampling for bubble-point testing and ISO 19438 multi-pass filtration testing. Only elements that meet all criteria are packaged, ensuring reliable protection for your grader’s engine.
Installing the 860140474 Oil-Water Separator Element requires relieving fuel system pressure. Clean the outside of the filter housing thoroughly. Remove the old element and discard it. Clean the inside of the housing with clean diesel fuel. Lubricate the new element’s gasket with a thin film of clean diesel. Install the element by hand until the gasket contacts the housing, then tighten an additional 1/2 to 3/4 turn. Do not overtighten. Prime the fuel system by pumping the hand primer until resistance is felt.
Inspect the 860140474 Oil-Water Separator Element every 250 hours by checking the water-in-fuel sensor and draining any accumulated water via the valve at the bottom of the housing. Replace the element every 500 hours or immediately if the engine shows signs of fuel starvation (loss of power, rough running). Store spare elements in a cool, dry place away from direct sunlight. Keep a spare element in your parts locker to avoid unplanned downtime.
Water in diesel fuel causes injector nozzle erosion, pump rust, and microbial growth in the tank. The genuine 860140474 Oil-Water Separator Element strips free water and breaks emulsions, allowing the water to settle into the collection bowl where it can be drained. Operators report fewer injector replacements and longer fuel pump life after switching to OEM filters. The high dirt-holding capacity also ensures consistent fuel flow between service intervals.
In a fleet study of 20 XCMG GR215 graders, those using genuine 860140474 Oil-Water Separator Elements experienced 80% fewer fuel system-related failures over 5,000 hours compared to machines using aftermarket filters. The improved water separation also reduced winter fuel gelling issues. For contractors who operate in humid or wet conditions, an OEM filter is a small investment with enormous protection value.
XCMG’s filter plant uses automated pleating machines to ensure consistent media spacing and bonding. The 860140474 Oil-Water Separator Element media is pleated to maximize surface area while maintaining low flow restriction. The center tube is made of epoxy-coated steel to resist corrosion. The end caps are bonded with high-strength urethane adhesive that withstands fuel exposure. Each element is 100% leak-tested and validated for water separation efficiency using ISO 4020 test stands.
All 860140474 Oil-Water Separator Elements are individually sealed in poly bags and packed in boxes of 6 or 12. Bulk orders of 24 or more are palletized. XCMG’s global distribution network ensures fast delivery to any location. For fleet operators, filter exchange programs are available to minimize inventory costs. Technical support for correct installation is available via the contact buttons above.
The 860140474 Oil-Water Separator Element directly replaces original part numbers 860140473 and 860140475. It is fully compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders equipped with Dongfeng Cummins 6BTAA5.9 engines. This element also fits the fuel filter/water separator assembly (part 860140470) used on these machines. For engines with a primary fuel filter only (without water separation), use part 860140476. Always verify your housing part number before ordering.
When replacing the element, also order a new drain valve seal kit (part 860140477) and water sensor (860140478) if equipped. XCMG recommends replacing the element every 500 hours or annually, whichever comes first. Keep a supply of 860140474 Oil-Water Separator Elements in your parts inventory for scheduled maintenance. For fleet operators, bulk orders of 24 or more elements include a 10% discount and free shipping.
For alternative micron ratings (e.g., 2-micron for ultra-high pressure systems), use the buttons above to contact our engineering support team. We can also supply elements with Viton seals for bio-diesel compatibility. Always provide your grader’s serial number and a photo of the existing filter housing when ordering the 860140474 Oil-Water Separator Element to ensure perfect fitment.
