The ARB Air Locking Differential (Air Locker) is a driver-controlled, pneumatic locking differential designed to give 100% traction on demand. When engaged, the Air Locker locks the differential gears, forcing both wheels on an axle to turn at the same speed, providing maximum traction in off-road conditions. This manual provides essential information for the safe and effective installation, operation, and maintenance of your ARB RD136 Air Locking Differential.
It is crucial to read and understand all instructions before attempting installation or operation. Improper installation or use can lead to serious injury, damage to the vehicle, or failure of the differential.

4. Pitunjuk Instalasi
Installation of the ARB Air Locker is a complex procedure that should only be undertaken by individuals with significant mechanical experience and the correct tools. This section provides a general overview; refer to the detailed installation manual provided with your Air Locker kit for specific steps and torque specifications.
- Persiapan: Safely lift and support the vehicle. Drain differential fluid and remove the differential cover. Remove axle shafts and the existing differential carrier.
- Ring Gear Transfer: Carefully remove the ring gear from the old differential carrier and install it onto the ARB Air Locker. Ensure proper alignment and torque specifications are met.
- Bearing Installation: Install new carrier bearings onto the Air Locker.
- Rute Jalur Udara: Drill and tap the axle housing for the air line bulkhead fitting. Route the air line from the differential to the compressor location, ensuring it is protected from heat and abrasion.
- Differential Installation: Install the ARB Air Locker into the axle housing. Set backlash and carrier bearing preload according to vehicle manufacturer specifications. This step is critical for differential longevity.
- Reassembly: Reinstall axle shafts, differential cover (with new gasket and proper sealant), and fill with new, correct specification differential fluid.
- Air System Connection: Connect the air line to the ARB air compressor and solenoid valve. Wire the compressor and switch according to the provided wiring diagram.
- Tés awal: With the vehicle safely supported, engage and disengage the Air Locker to confirm proper operation and check for air leaks.
Note: Always use new bearings, seals, and gaskets during installation. Refer to your vehicle's service manual for specific differential setup procedures.
5. Parentah Operasi
The ARB Air Locker is designed for off-road use only. Engaging the locker on hard, high-traction surfaces (like pavement) can cause severe damage to the differential, axle shafts, and other drivetrain components.
- When to Engage: Engage the Air Locker when you anticipate a loss of traction, such as in mud, sand, snow, or rocky terrain. It is best to engage before losing momentum.
- Engagement Procedure:
- Bring the vehicle to a near stop or very slow speed.
- Press the Air Locker engagement switch. You should hear the compressor activate and then the solenoid click as the locker engages.
- A dash indicator light (if installed) will confirm engagement.
- When to Disengage: Disengage the Air Locker immediately when you regain traction or when returning to high-traction surfaces.
- Disengagement Procedure:
- Press the Air Locker disengagement switch.
- The locker may require a slight turn of the wheels or a brief, gentle acceleration/deceleration to fully disengage the internal locking mechanism.
- The dash indicator light will turn off when disengaged.
- Setir: With the Air Locker engaged, steering will be significantly affected, especially in the front axle. Exercise caution and reduce speed.
6. Pangropéa
Regular maintenance ensures the longevity and reliable performance of your ARB Air Locker.
- Cairan diferensial: Check and change differential fluid at recommended intervals by your vehicle manufacturer, or more frequently if operating in harsh conditions (e.g., water crossings). Use only high-quality, correct specification gear oil.
- Air Line Inspection: Periodically inspect the air line for kinks, chafing, or damage. Ensure all connections are secure and free of leaks.
- Air Compressor Maintenance: Refer to your ARB air compressor manual for its specific maintenance requirements, which typically include checking the air filter and draining any moisture from the tank.
- Engagement Test: Occasionally engage and disengage the Air Locker (in a safe, off-road environment) to ensure it operates smoothly.
7. Cara ngungkulan
If you encounter issues with your ARB Air Locker, consult the following common troubleshooting steps. For complex issues, contact ARB technical support or an authorized service center.
| Masalah | Mungkin Cukang lantaranana | Solusi |
|---|---|---|
| Locker not engaging | No air pressure; electrical issue (switch, solenoid, wiring); air leak; internal differential issue. | Check compressor operation and air pressure. Verify electrical connections and fuse. Inspect air lines for leaks. If problem persists, professional inspection is required. |
| Locker not disengaging | Residual air pressure; internal mechanical binding; solenoid stuck. | Ensure air pressure is released. Drive slowly and turn wheels slightly to allow disengagement. Check solenoid for proper operation. |
| bocor hawa dideteksi | Loose fittings; damaged air line; faulty O-rings or seals within the differential. | Tighten all air fittings. Inspect air line for damage and replace if necessary. If leak is from differential, professional repair is needed. |
