How to use the differential lock on the FAW JH6?

[HarrisonFitz]

The differential lock on the FAW JH6 is controlled via the differential lock switch located on the dashboard in the cabin. Here is an introduction to the differential lock: 1. Introduction to differential lock: The central differential lock is a locking mechanism installed on the central differential, primarily used in four-wheel-drive vehicles. 2. Classification of differential locks: (1) Forced locking type: The forced locking differential lock is set on an ordinary symmetrical bevel gear differential. This type of differential lock has a simple structure, is easy to manufacture, and has a high torque distribution ratio. (2) High-friction self-locking type: The high-friction self-locking type includes structures such as friction plate type and slider cam type. (3) Torsen type: The Torsen differential is a new type of inter-axle differential. (4) Viscous coupling type: Some four-wheel-drive cars use a viscous coupling as a differential.

Operating the differential lock on the FAW JH6 is actually quite straightforward, just remember these three steps. Experienced drivers who've handled this truck know - when encountering mud or slope slippage, first come to a complete stop! Keep your right foot firmly on the brake, then press the yellow differential lock button beside the gear lever with your left hand. Wait until the lock icon lights up on the dashboard and you hear a 'click' sound - that means it's engaged. You'll notice the tires stop spinning and the truck can climb out steadily. But remember, this feature should only be used for low-speed traction. It automatically disengages when speed exceeds 20 km/h, and never drive with differential lock engaged on paved roads during turns - it damages the vehicle!

I've worked on quite a few FAW Jiefang trucks, and the key to using the JH6's differential lock is timing. There's a knob or button under the steering wheel—don't wait until the wheels are spinning freely to press it. Activate it when the tires just start to show signs of slipping, after stopping and shifting to neutral. The differential lock indicator on the dashboard will light up. Important reminder: Always remember to turn it off before making a turn, otherwise the rear axle gears will bind. Last time, a driver forgot to unlock it on concrete and burned out the differential oil seal after just three kilometers. After driving on rough roads, it's advisable to have the mechanic check the differential lock connector for mud or water during maintenance, as it can easily cause poor contact.

The differential lock is not a universal solution. When using the JH6 to escape difficult terrain, you must first stop, shift to neutral, and then press the switch. Once the indicator light is confirmed to be on, start smoothly and immediately. The system will automatically unlock if the speed exceeds 15 km/h. Remember, it is prohibited to use on paved roads, and forcing its use during turns can lead to abnormal tire wear or even damage to the drive shaft. After use in rainy or snowy conditions, always check if the exhaust vent is blocked.

For beginners using differential locks, remember these four key points: 1. Bring the vehicle to a complete stop. 2. Shift the gear to neutral. 3. Press the physical button with the lock icon on the center console. 4. The operation is only effective when the red differential lock symbol appears on the dashboard. After operation, lightly press the accelerator; if you feel the vehicle body being dragged, it means it's working. Turn it off as soon as you're out of trouble. Driving with the differential lock engaged on flat roads while turning, you'll hear the clashing sound of gears from the rear axle. It's recommended to press the button twice a month to maintain contact activity.

The principle of the differential lock is to force the left and right wheels to rotate synchronously. The switch for the FAW JH6 is usually located near the gear lever, a round button with a lock symbol. There are three key points to note in actual use: ensure the wheels are completely stationary before activation, otherwise gear collision damage may occur; perform unlocking operations only when the vehicle is fully stopped; check for aging electromagnetic valve wiring during seasonal maintenance each year. Special reminder: when the differential lock indicator on the dashboard flashes, it indicates a system malfunction requiring a 10-minute power disconnection for reset. This feature is particularly useful in muddy construction sites, but it should not be used as a daily driving aid.
