FAW J6P Window Regulator: Desconstruindo 4 Critical Parts for Flawless Manual Operation

Welcome to this essential technical guide on the FAW J6P Window Regulator, specifically the manual version for the FAW Jiefang CA3250P66K2L1T1E 6×4 caminhão despejando. This analysis deconstructs the 4 critical component types that create this robust, hand-cranked lifting system for ultimate reliability.

This specific FAW J6P Window Regulator is designed for models configured with manual windows, prioritizing durability and failsafe operation over electrical convenience. In a heavy-duty dump truck, an electric motor can be a failure point when exposed to water and dust. This manual system relies on a robust gear-driven assembly, connection plates, and specialized fasteners to provide smooth, reliable window operation for the life of the vehicle.

Essencial 1: The ‘Manual Lift’ Lógica (The Regulator Assembly)

This is the core component of the FAW J6P Window Regulator sistema. It is the complete mechanical assembly that converts the driver’s rotational hand-crank motion into the vertical lifting force for the window.

1. Componente: ‘Left/Right front door window regulator assembly’ (6104015-B27-C00 / 6104020-B27-C00) – Quantidade 1 cada
Esse (Comp. 1) é o completo, manually-operated regulator. The ‘B27-C00’ part number signifies this is the manual version, distinct from the electric (AA01) variante. It includes the scissor-lift arms and the central gearbox, supplied as mirrored left and right units.

The Mechanical Logic is its primary feature. Instead of an electric motor, this unit has a robust gearbox (likely a self-locking worm gear) with an input shaft. The interior window crank handle (sold separately) attaches directly to this shaft.

When the driver turns the crank, this gearbox multiplies their torque, smoothly driving the scissor-lift mechanism to raise or lower the heavy glass. The self-locking nature of the gear means the window stays exactly where it is left and cannot be forced down from the outside.

The Durability Logic is the entire reason for this design’s existence. In a dump truck, simplicity equals reliability. This manual FAW J6P Window Regulator has no wires to chafe, no motors to burn out from water ingress, and no switches to fail from dust. It is a purely mechanical, sealed-gear system designed for failsafe operation in the harshest environments.

The Service Logic is also straightforward. Failure is rare, but if it occurs (Por exemplo, a stripped gear from extreme force), the entire assembly is replaced as one unit. It is mounted inside the door using the hardware from Core 3.

Essencial 2: The ‘Structural Mount’ Lógica (The Connection Plate)

This component acts as the rigid foundation or “adapter plate” for the entire FAW J6P Window Regulator. It is the critical structural link between the regulator and the door’s inner panel.

1. Componente: ‘Left/Right front door inner panel connection plate assembly’ (6101415-A01 / 6101420-A01) – Quantidade 1 cada
Esse (Comp. 2) is a heavy-gauge, stamped-steel plate. Como um “conjunto,” it is precisely formed with all the necessary mounting holes and captive nuts to accept the regulator.

The Load-Bearing Logic is its primary function. O regulador da janela (Comp. 1) attaches to this plate, and this plate, por sua vez, attaches to the door’s structural guide rails. It bears the entire weight of the window and the operational torque from the crank.

Its rigidity is essential. If this plate were to flex, the regulator’s scissor-arms would go out of alignment, causing the window to bind, Jam, ou “pop” out of its channels. This component ensures the FAW J6P Window Regulator remains perfectly aligned.

The Serviceability Logic is also key. This plate often serves as the “service panel.” A technician can remove this entire plate (with the regulator attached) from the door’s access hole, making it much easier to service the regulator or replace the glass.

Essencial 3: The ‘Vibration-Proof’ Lógica (O sistema de fixação)

This final group represents the 16 specialized, high-strength fasteners that hold the FAW J6P Window Regulator sistema juntos. Their design is 100% focused on vibration resistance.

1. Componente: 'Parafuso flangeado hexagonal’ (Q1840612) – Quantidade 12
Esse (Comp. 3) is the primary structural fastener. O “flanged” head is a built-in washer, which distributes the clamping load over a wide area, preventing the bolt from pulling through the sheet metal.

The high quantity of 12 (6 por porta) is used to rigidly secure the connection plate (Comp. 2) to the door’s inner structural rails. The flange also acts as a locking mechanism when torqued, providing excellent vibration resistance.

2. Componente: 'Porca hexagonal (para manual)’ (CQ34006) – Quantidade 4
Esse (Comp. 4) is a specialized nut. O “para manual” note indicates these are likely the fasteners used to attach the window glass itself to the regulator’s saddle (the part that moves up and down).

These nuts must provide a secure clamp on the glass without causing a stress fracture. They are a critical part of the FAW J6P Window Regulator sistema, as they are the final link in transferring the lifting force to the glass. They are almost certainly paired with bolts and rubber grommets that are part of the glass assembly.
