SINOTRUK HOWO TRUCK SPARE PARTS Rear Axle Oil Filter WG7117337170
FUNCTION
1. Filtration of Impurities in Rear Axle Lubricant: This filter element is installed within the lubrication system of the drive axle (rear axle/axle assembly). Its primary function is to capture and remove metal wear debris, dust, carbon deposits, moisture, and other minute particulate contaminants present in the gear oil circulating within the axle housing. This prevents these impurities from circulating through the fluid, thereby averting wear or damage to critical components such as gears, bearings, and differentials.
2. Protection of the Drive Axle System: By maintaining the cleanliness of the rear axle fluid, the filter extends the service life of the drive axle system and reduces the incidence of mechanical failures. This is particularly beneficial for vehicles-such as dump trucks and tractor units-operating under heavy loads, over long distances, or in harsh road conditions.
3. Preservation of Fluid Performance: Through continuous filtration, the unit ensures that the specialized rear axle gear oil (e.g., GL-5 85W-90) retains its optimal lubricating, cooling, and anti-oxidation properties, thereby indirectly enhancing the vehicle's overall transmission efficiency and fuel economy.
Operating Principle
1. Dry Adsorption Filtration: The oil enters from the exterior of the filter element; as it passes through the high-strength filter paper or multi-layer filtration media, impurities are trapped on the surface or within the media structure, while the clean oil flows out from the center into the axle housing's circulation system.
2. Filtration Precision: Typically capable of effectively filtering particles in the 10–50 micron range; it offers high efficiency and low pressure drop, ensuring no interference with the normal operation of the oil pump.
3. Passive Operation: Requires no external power source; filtration is achieved solely by relying on the inherent flow pressure of the rear axle oil itself.
Advantages
| No. | Performance Advantage Category | Detailed Description |
|---|---|---|
| 1 | High-Efficiency Filtration Performance | Uses high-quality multi-layer composite filter paper with high filtration efficiency, effectively capturing metal debris, dust, carbon deposits, and other contaminants at 10-50 microns; low flow resistance (low pressure drop), ensuring smooth oil circulation without affecting normal lubrication system pressure. |
| 2 | Extended Component Service Life | Effectively protects the rear axle differential, wheel-end reducers, bearings, and gears, reducing wear, pitting, and seizure risks; high-capacity design can handle more contaminant accumulation, especially suitable for heavy-duty, mining, and long-haul harsh conditions, significantly extending the overall service life of the drive axle. |
| 3 | Strong Durability and Stability | Robust metal housing provides excellent vibration and impact resistance; high-performance sealing ring offers superior high-temperature and oil-aging resistance with excellent leak-proof performance; optimized structure with high pressure resistance, maintaining stable performance under heavy truck bumpy conditions. |

Recommended Replacement Intervals
1. Initial Replacement: After the vehicle has traveled 2,000–5,000 km, the rear axle gear oil and filter element must be replaced simultaneously.
2. Standard Replacement Interval:
Every 40,000–60,000 km or 10 months (whichever comes first).
3. Heavy-Duty Operation, Mining Applications, or Harsh Road Conditions: It is recommended to shorten the interval to 30,000–40,000 km.
4. Inspection Frequency: Every 10,000 km or during every Level 1 maintenance service, check the rear axle oil level and inspect the filter element for any signs of severe clogging or damage.
