FAW J5P J6H 1109010-Q461 Air Filter Assembly Engine Truck Spare Parts

The Air Filter Housing Assembly (Part No. 1109010-Q461) is an original equipment (OE) component produced by FAW Jiefang, designed specifically for heavy- and medium-duty commercial trucks in the FAW J6 series. As a core element of the engine intake system, this assembly houses the primary and secondary air filter elements, ensuring that only clean, filtered air enters the engine combustion chamber.

Constructed from high-strength engineering plastics or coated metal materials, it delivers excellent resistance to vibration, extreme temperatures, and harsh environmental conditions commonly found in mining, construction, and long-haul transportation. With optimized internal airflow design and robust sealing performance, this air filter housing plays a critical role in protecting the engine from abrasive dust, sand, and particulate matter — significantly reducing cylinder wear and preventing costly failures such as "cylinder scoring" (scuffing).

Usage & Maintenance Guidelines (Critical Instructions)

Regular Inspection & Filter Replacement
→ Replace the main filter element every 10,000 – 20,000 km, depending on operating conditions.
→ In high-dust environments (mines, construction sites), shorten interval to 5,000 – 10,000 km.
Proper Cleaning Procedure (If Applicable)
→ Only dry-type filters — never wash with water or oil-based cleaners.
→ Can be cleaned up to three times using compressed air at ≤ 0.3 MPa (3 bar / 43 psi), blowing from the inside out to avoid damaging filter media.
→ After three cleanings, replace regardless of appearance.
Safety Core Handling
→ The inner safety filter (1109070-Q461) is non-cleanable and non-reusable.
→ If the primary filter shows signs of damage or collapse, replace both the main and safety cores together.
Ensure Perfect Seal During Installation
→ Check rubber seals, clamps, and housing joints for cracks or deformation.
→ Tighten all hose clamps securely — even minor leaks allow unfiltered air bypass, increasing piston and cylinder wear by 3x to 5x.
Monitor Air Restriction Indicator
→ If the dashboard warning light activates or the mechanical vacuum indicator pops into red zone, inspect immediately.
→ Prolonged operation under high restriction leads to reduced power, increased fuel consumption, and turbocharger stress.
Avoid Water Ingestion
→ Never operate with wet filter media. Moisture clogs pores, drastically increasing intake resistance.
→ Ensure the water deflector plate at the air intake inlet is intact, especially during rainy or flooded conditions.
Check Intake Duct Integrity
→ Inspect connected hoses and ducts for cracks, loose connections, or rodent damage.
→ Any breach upstream of the filter compromises filtration efficiency.
