Radar Gearbox Overhaul 55892265
My car, equipped with an advanced and complex drive system, faced a disturbing problem characterized by a constant whining sound coupled with vibration at high speeds, in addition to a noticeable delay in torque transfer response.
I tried to fix the problem by visiting a number of conventional garages in Kuwait, but they all refused to work on the car due to the complexity of the internal drive system specific to this type of modern Chinese technology.
Intensive Search for Required Specialization
I decided to search for a specialized center for Geely vehicles and its various models, and eventually landed at Sharara Auto Garage.
Upon arrival, I discovered that the team had extensive knowledge and distinguished experience in dealing with the complex Radar gearbox system. They conducted a comprehensive diagnostic check using the latest technology, revealing that the problem was caused by wear in the internal gear bearings and the reduction unit of the gearbox, necessitating a precise overhaul process.
Professional Execution of the Radar Gearbox Overhaul
The Radar gearbox overhaul process was carried out with high efficiency:
Measured Disassembly: The entire drive unit was dismantled in a clean environment, and the damaged parts—gears, bearings, and seals—were replaced using excellent quality spare parts.
Specialized Equipment: The technicians utilized modern equipment for the precise reassembly of the unit, followed by an electronic adjustment of the control unit to ensure perfect compatibility between the new parts and the car’s electronic system.
Competitive Prices and Outstanding Service
After completing the Radar gearbox overhaul and test driving the car, I was pleasantly surprised with a significant discount of 45% on the total cost of the repair and spare parts.
This discount made the invoice significantly lower than the quotes I received from other non-specialized centers, adding true value to the experience. I not only received a car that operates with factory efficiency and a full warranty, but also significant financial savings. Sharara Auto Garage proved to be the optimal and most suitable choice for anyone owning an advanced Chinese car in Kuwait 55892265.
Definition of Radar Gearbox Overhaul
The concept of Radar gearbox overhaul refers to the comprehensive repair and restoration of the Electric Axle (e-Axle), which is the part responsible for transferring power and torque from the electric motor to the car’s wheels.
This unit represents an integrated system combining reduction gears and the electric motor, and in some cases also includes the Inverter.
1. Conditions Requiring the Radar Gearbox Overhaul Process
The overhaul process is considered necessary when the unit suffers internal mechanical damage, which may result from:
Wear of Reduction Gears: Damage occurs that affects the function of the gears responsible for reducing motor speed and increasing torque.
Bearing Damage: Bearings responsible for the efficient rotation of the axle or motor fail.
Oil or Coolant Leakage: Leads to the internal components drying out, increasing friction and harming performance.
2. Key Components and Procedures in the Radar Gearbox Overhaul
This process focuses on precisely replacing the damaged parts to ensure optimal repair, including:
Replacement of Gears and Bearings: Changing the damaged parts, such as gears that emit unusual noises like whining or grinding, and worn bearings.
Changing Seals and Inhibitors: Ensuring the integrity of the seals to prevent the leakage of the specific lubricating oil for the electric drive unit.
Electronic Calibration: After the mechanical repair is completed, an electronic adjustment and calibration is performed on the Drive System Control Unit (PCU/VCU) to ensure compatibility between the new components and the car’s electronic system.
In summary, the Radar gearbox overhaul is a specialized maintenance process for the electric drive unit, aiming to address mechanical damage that causes noise and vibrations, restoring the component to its operational efficiency in the best possible way.
Reasons for Radar Gearbox Overhaul
Radar vehicles face multiple problems in the drive system that sometimes require a gearbox overhaul process for the Electric Axle unit, and these problems are often focused on mechanical or hydraulic faults. Here are the main points related to these faults:
1. Mechanical Problems:
Issues resulting from wear in the gears and bearings are considered the most common and require the unit to be fully dismantled:
Wear of Speed Reduction Gears:
Causes: Driving under heavy loads for extended periods or a lack of quality or quantity of the necessary axle oil for cooling and lubrication.
Symptoms: Hearing whining or humming sounds that increase with speed, indicating abnormal friction between gear teeth.
Axle Bearings Failure:
Causes: The end of the bearings’ lifespan or exposure to excessive pressure leading to their damage.
Symptoms: Hearing grinding or friction sounds with noticeable vibration in the wheels at certain speeds, directly affecting driving smoothness.
2. Hydraulic Problems:
These relate to the quality of the internal performance of the drive unit, especially concerning the seals:
Seal Damage and Lubricating Oil Leakage:
Causes: Deterioration of the rubber seals responsible for preventing oil leakage inside the unit.
Symptoms: A clear drop in the internal lubrication oil level, and even minor external leakage in some cases. This results in increased friction and gear wear, in addition to the possibility of warnings appearing that indicate high drive unit temperature.
3. Importance of Specialized Expertise at Sharara Auto:
Expertise in Electric Axle (e-Axle) Systems:
Repairing these units requires trained and qualified technicians to handle the complex systems of disassembly, installation, and precise calibration.
