FAW J6P Air Filter: Deconstructing 36 Critical Parts for Flawless Engine Breathing

Welcome to this expert deconstruction of the FAW J6P Air Filter (Main Assy P/N 1109010-50V). This is the complete “engine breathing” assembly for the FAW Jiefang CA3250P66K2L1T1E 6×4 dump truck. This is a 36-component “Logic Assembly” designed to provide 100% clean, debris-free air to the turbocharger in the most extreme, dusty, off-road conditions.

The “Dual-Stage Filtration Logic” is the key to this FAW J6P Air Filter. The main housing (Comp 13) contains *two* filters: a ‘Main filter element’ (1109070-76A) and a ‘Secondary filter element’ (1109060-50V). The “Main Logic” of the large filter is to stop 99.9% of all dust. The “Failsafe Logic” of the smaller, inner ‘Secondary’ filter is to protect the engine *while the main filter is being serviced*. If a technician removes the main filter, this safety element prevents any dirt (or a dropped bolt) from being sucked directly into the turbocharger, which would instantly destroy it. This dual-filter design is essential for heavy-duty, off-road applications.

This technical guide is an essential resource for chassis technicians, fleet maintenance managers, and parts specialists. We will deconstruct the entire 36-component group. We will analyze the “Filtration Core Logic” (the main FAW J6P Air Filter housing and its dual elements), the “Clean Air Plumbing Logic” (the “clean-side” pipes connecting the filter to the engine), the “Pre-Filter Snorkel Logic” (the high-mount air intake), and the “Structural Mounting Logic” (the heavy-duty brackets and clamps).

Core 1: The “Filtration Core” Logic (Components 6, 13)

This group forms the “heart” of the FAW J6P Air Filter. It is the main housing and the serviceable elements that do the actual work of cleaning the air.

1. Component: ‘Air filter assy’ (1109010-50V)
This (Comp 13) is the “Main Housing Logic.” It is a large, heavy-duty canister. Its “logic” is to create a perfectly airtight seal, separating the “dirty side” (from the snorkel) from the “clean side” (going to the turbo). It is designed to be chassis-mounted and withstand extreme vibration and weather.

2. The “Dual-Element” Logic (Internal to Comp 13):
Inside the main assembly are two critical parts: the ‘Main filter element assy’ (1109070-76A) and the ‘Secondary filter element assy’ (1109060-50V). The “Main Logic” of the large element is its massive surface area of pleated paper, which traps 99.9%+ of all airborne abrasives (dirt, dust, silica).

The “Failsafe Logic” of the ‘Secondary’ (inner) element is just as important. Its *only* job is to protect the engine *during service*. When a technician removes the main filter, the turbocharger inlet is exposed. This safety filter prevents any dirt (or a dropped nut, or a shop rag) from being sucked directly into the turbo. This is a non-negotiable feature for any “in-field” serviceable FAW J6P Air Filter.

3. The “Service” Logic (Component 6, 1109263-50A, 1109264-50A)
This is the “Sealing & Access Logic.” The ‘Connecting base assy’ (Comp 6) is the main “flange” of the FAW J6P Air Filter, which provides the “clean air outlet” and the mounting surface. The ‘Lower end cover’ (a sub-part of Comp 6) is the removable cap that provides service access to the filters. It uses a ‘Seal plate’ (Comp 6-sub) and 11 ‘Support plates’ (Comp 6-sub) to create a perfect, airtight seal. IS

Core 2: The “Pre-Filter (Snorkel)” Logic (Components 1, 3)

This group forms the “dirty air inlet” side of the FAW J6P Air Filter. Its logic is to pull air from the cleanest possible location.

1. Component: ‘Air inlet duct assy’ (1109230-61B-C)
This (Comp 1) is the “Snorkel Logic.” On a heavy-duty dump truck, the air at “road level” is a cloud of fine, abrasive dust, dirt, and water spray. This “snorkel” “logic” is to move the air intake *as high as possible* (often above the cab).

This “High-Mount Logic” is a “pre-filter” in itself. The air 10 feet off the ground is dramatically cleaner than the air at bumper level. This “logic” does the *first* stage of separation, allowing the main FAW J6P Air Filter element (Comp 13) to last *thousands* of miles longer between services, saving the operator time and money.

2. Component: ‘Damper bracket assy-air inlet’ (1109220-50A)
The list calls for five (5) of these (Comp 3). This is the “Anti-Fatigue Logic” for the snorkel. A long, plastic snorkel tube (Comp 1) will vibrate violently from the engine and wind. Without support, it would “fatigue” and “shatter.” These five “damper brackets” are the “Structural Logic” that rigidly anchors the snorkel to the truck’s cab, making it strong, silent, and vibration-proof.

Core 3: The “Clean Air Plumbing” Logic (The “Clean” Side)

This group represents the *most critical* plumbing in the entire FAW J6P Air Filter system. This is the “clean side,” and its integrity is non-negotiable.

1. The “Flex Logic” (Components 5, 26, 33, 34, 36)
This is the “Engine Movement Logic.” The FAW J6P Air Filter housing (Comp 13) is mounted rigidly to the truck’s *chassis*. The engine and turbocharger are “floating” on *engine mounts*. The engine “rocks” and “twists” (by several inches) every time the truck accelerates.

A “rigid pipe” here would snap instantly. The “logic” is to use a system of “Flexible Hoses” and “Rigid Pipes.” The ‘Connecting hose assy’ (Comp 5), ‘Connecting hose’ (Comp 33), and ‘Connecting pipe-engine’ (Comp 36) are the “flex joints.” These rubber/silicone hoses are designed to *absorb* this movement, protecting the rigid components from cracking.

2. The “Airtight Logic” (Critical Failure Point)
This plumbing (Comp 5, 11, 24, 26, 33, 34, 36) is *after* the filter. This is the “clean” air path. A failure here is *more catastrophic* than a failure in the snorkel (Comp 1). If one of the ‘Worm-drive hose clamps’ (Comp 4, 10, 12, 23, 25, 32, 35) is loose, or if a hose (Comp 5) cracks, the turbocharger will *suck in* dirty, unfiltered, abrasive road dust. This “Dusting” “logic” will destroy the turbocharger’s compressor wheel (at 100,000 RPM) and sandblast the engine’s piston rings and cylinder walls, leading to a complete engine rebuild. The FAW J6P Air Filter‘s plumbing is its most critical safety system.

Core 4: The “Structural Mounting” Logic (All Others)

This final group’s “logic” is to provide a heavy-duty, vibration-proof “cradle” for the FAW J6P Air Filter housing and its plumbing.

1. The “Cradle” Logic (Components 7, 14, 15, 27)
The ‘Air filter assy’ (Comp 13) is extremely heavy, especially when full of dirt. It cannot just hang. The “logic” of this system is a “multi-point mount.” It is supported by an ‘Air filter front support’ (Comp 14), an ‘Air filter rear support’ (Comp 15), and a ‘Support assy’ (Comp 27). This “Cradle Logic” distributes the load and vibration across multiple points on the chassis, ensuring the FAW J6P Air Filter housing will not crack from fatigue.

2. The “Hardware & Clamp” Logic (All remaining parts)
This is the “Vibration-Proof Fastener Logic.” The system uses a massive number of bolts, nuts, and washers (Comp 2, 8, 9, 16, 17, 18, 19, 20, 21, 22, 28, 29, 30, 31) to secure these heavy brackets to the frame. The “logic” of using ‘Hex flange lock nuts’ (Comp 2) or ‘Spring washers’ (Comp 17, 20) is “Anti-Loosening.” They provide constant tension, which is the only way to stop a bolt from “walking” loose on a heavy-duty dump truck.

The ‘Worm-drive’ (Comp 4, 12) and ‘Heavy-duty’ (Comp 23, 25, 32, 35) clamps are the “Airtight Logic.” They provide the 360-degree seal on all flexible hoses, which is the final component of a reliable FAW J6P Air Filter system.
