About maintenance of taxi / limo vehicles used for Narita Airport transfers

Mechanic

Mechanic

In order for our customers to be able to reach their destination safely or not to miss their flights, we work on vehicle maintenance with the company's pride.

Rather than replacing and maintenance after the initial symptoms appear or after breaking, we thoroughly check the durability distance and number of days of each part and replace it in advance.

In particular, we carefully maintain undercarriage parts that may lead to a major accident and electrical parts that may cause vehicles impossible to drive.

Basic parts are thoroughly inspected and replaced by 3-month inspection and periodic replacement.
Consumable parts are completely inventory managed in-house, and we organize system which can maintenance and replacement immediately.

All replacement parts are domestic products.

Taxi / limo undercarriage parts replacement 【Example】

Undercarriage parts

Undercarriage parts

●Hub bearing
If you continue to use it while it's deteriorated, it will lead to derailment in the worst case. Those parts are strictly controlled with mileage and 3-month inspection.

We use car parts from NSK, which are installed as the genuine part.


●Brake pads
We use brakes pads from Hitachi, that can withstand braking at high-speeds.


●Brake rotor
The brake pads are pressed against the steel brake rotor and slows down due to the frictional force.
We use a reliable brake rotor from Hitachi.


●Drive shaft
It's a part that transmits the power of the engine to the wheels.
If deterioration of rubber or tearing of the boot is found, we will immediately replace it with domestic remanufactured parts.

●Alternator
The role of the alternator is "power generation".
Since there is no initial symptom before the breakdown, if it breaks, it will soon become impossible to drive.
We replace it at the specified distance of domestic remanufactured parts.


●Starter motor
The role of the starter motor is "a part that plays an important role in starting the engine."
There is no initial symptom before the breakdown and it suddenly becomes impossible to drive. We are replacing it with domestic remanufactured parts at the specified distance.


●Battery
We check the voltage every 3 months and if it drops even a little, we replace it with a Panasonic "caos battery".


●Ignition coil
The role of the ignition coil is "a component that generates the high voltage required to ignite a gasoline engine."
If it breaks down, the speed will become unstable and you will not be able to drive after a while.
Since there is no initial symptom, it's replaced at the specified distance for Hitachi parts which we use.

●Cam position sensor
The role of the cam position sensor is to "calculate and control the fuel injection timing and ignition timing."
If it breaks down, it's not be able to drive. Since there is no initial symptom, we replace it with a Hitachi part at the specified distance.


●Spark plug
The role of the spark plug is to "produce sparks to ignite the fuel".
If it breaks down, the speed will become unstable and it will not be able to drive after a while.
It's replaced at the distance specified for the DENSO RX plug.


●Fuel pump
If the motor of the fuel pump breaks down, fuel will not be sent from the tank containing gasoline and it will not be possible to drive.
Since there is no initial symptom, we replace at the specified distance for only the motor part with domestic parts.


●Air mass sensor
The air mass sensor is a device that detects the amount of intake air so that the air-fuel ratio is commensurate with the operating condition of the engine.
If it breaks down, the speed will become unstable and it will not be able to drive after a while.
Since there is no initial symptom, it's replaced at the distance specified for genuine domestic parts.

Other periodic replacement parts【Example】

●Fan belt
It's a belt that takes power from the rotation of the crankshaft of the engine and drives the engine mechanism (alternator, water pump, air conditioner compressor, etc.) necessary to move the car.
We check the condition of fan belts by 3-month inspection and replace it at every automobile safety inspection.


●Air filter
The role is to clean the air and supply clean air to the engine so that dust and sand don't get inside the engine.
We replace it regularly at the specified distance.


●Oils
Engine oil, ATF oil, and gear oil are regularly changed at the specified distance.


●Air conditioner filter
It has the role of removing dust and sand from the air taken in from the outside and circulating clean air inside the car. It's also the cause of bad odors, so we replace it regularly within the specified period.

Inspection by drivers before each operations【Example】

Inspection by driver

Inspection by driver

Our drivers carry out inspections every day when they come to work.
We are introducing important inspection items.

●Amount of engine oil, cooling water
Since we operate transportation on the highway every day, our drivers check the amount of engine oil and cooling water without fail.


●Tension of the fan belt
Our drivers check that the rubbers aren't cracked and the tensions are appropriate.


●Tire pressure
Our drivers check that the air pressures are appropriate, tire grooves, rubber wrinkles and tires not stepping nails, etc.
