Since its establishment in 1973, Showa Co., Ltd. has been engaged in the rebuilding and repair of injection pumps. In 1987, we became the first Bosch Diesel Workshop in Japan and have quickly responded to the needs of imported vehicles such as Mercedes-Benz and VW. We are also working on new electronic types. If you have any issues with injection pumps, please feel free to consult us. 【Manufacturers We Handle】 ■BOSCH ■DELPHI (CAV) ■STANADYNE ■Continental (VDO) ■ZEXSEL ■DENSO 【What is Rebuilt?】 Rebuilt parts refer to regenerated mechanical components. Utilizing specialized regeneration technology, rebuilt products can be restored to performance levels comparable to new ones. In recent years, there has been a growing commitment to promoting recycling on a global scale, and it has already become a new norm that "turbo and injection pumps are rebuilt products." *For more details, please refer to the PDF document or feel free to contact us.

At Showa Corporation, we operate as an agent, providing repair and rebuilding services for turbochargers, injection pumps, testing equipment, and other parts. We support manufacturers such as GAC, a company based in the United States that specializes in engine governing systems, as well as Carbon Zapp, which manufactures testers for injectors used in clean diesel and direct-injection gasoline engines. If you are experiencing issues with repairs or rebuilding, please feel free to consult with us. 【Manufacturers We Handle】 ■ GAC ■ Carbon Zapp *For more details, please refer to the PDF document or feel free to contact us.

Since our establishment, we have specialized in the repair and rebuilding of fuel injection pumps and turbochargers. Rebuilding refers to the process of restoring mechanical parts to a like-new condition. Using specialized regeneration technology, we can restore performance that rivals that of new products. In recent years, there has been a growing commitment to promoting recycling on a global scale, and it has already become a new norm that "turbochargers and injection pumps are rebuilt products." Our ability to handle these two areas is one of our strengths. 【Main Rebuilt Products】 ■ Injector measuring instruments ■ Injector testers ■ High-speed balance measuring machines ■ Balance measuring machines (for vehicles to ships) *For more details, please refer to the PDF document or feel free to contact us.

Since our establishment, we have specialized in the repair and rebuilding of fuel injection pumps and turbochargers. Our rebuilding technology compiles the details of our work into a record, ensuring that each item is handled with care. Blast cleaning is performed manually, and visual inspections are conducted with the keen eyes of skilled craftsmen. Additionally, both turbos and pumps undergo 100% testing. If you are having trouble with repairs, please feel free to consult us. 【Features】 ■ "Unique Standards" - Work details compiled into a record ■ "Thorough" - Disassembly → Cleaning → Measurement ■ "Trust and Reliability" - Fair pricing *For more details, please refer to the PDF document or feel free to contact us.

A turbocharger is a type of air pump that reuses the energy from engine exhaust gases that would normally be wasted. The exhaust gases first drive the turbine wheel assembly. This part is connected to the compressor wheel. As the connected compressor wheel rotates, it is possible to send a large amount of air into the engine's combustion chamber in a compressed state. Since the compressed air has increased density, it allows for more fuel to be injected, which is why a turbocharged engine can produce greater horsepower than a non-turbo engine of the same size. *For more details, please refer to the PDF document or feel free to contact us.*

Turbocharger failures are mostly caused by external factors. Despite failures caused by reasons other than the turbocharger, if the abnormalities are not detected and there are no countermeasures, replacing the unit will lead to similar failures. 【Examples of Turbo Failure Causes】 ■ Troubles related to lubricating oil ■ Damage due to foreign object intrusion on the intake or exhaust side ■ Contamination of lubricating oil with foreign substances ■ Poor engine compression and blow-by ■ Excessive rise in engine exhaust temperature ■ Troubles due to installation errors ■ Malfunction of the actuator 【About Us】 At Showa Co., Ltd., we provide "rebuilt technology" that utilizes specialized regeneration techniques as an authorized dealer for turbo manufacturers worldwide, regenerating mechanical parts to a quality comparable to new. We cater to a wide range of needs from light vehicles to imported cars, trucks, construction machinery, and ships. *If you have any issues with turbos or injection pumps, please consult us first!

The turbo of a turbocharger spins at high speeds of about 100,000 to 250,000 RPM. What happens if the balance is off? Unbalanced tires cause vibrations and result in a very uncomfortable ride. In the case of a turbo, if it is unbalanced, not only will it fail to perform at its best, but in the worst case, it can lead to damage issues. Our company uses two types of balance testers to perform balance corrections with higher precision than new ones. Please feel free to consult us. *For more details, please refer to the PDF document or feel free to contact us.

Our company also supports three components of the common rail system: "high-pressure pump," "accumulator rail," and "injector." The high-pressure pump is responsible for pressurizing the fuel and sending it to the rail. If it fails, it cannot create the proper pressure, leading to issues such as engine starting difficulties. Some repairs may be possible, so please contact us. The accumulator rail acts like a tank that stores high-pressure fuel. Easy repairs are dangerous and generally not possible. It is common to replace it with a new one. The injector is the most critical component of the common rail system, performing the complex task of injecting fuel into the cylinder. Typically, the only option is to replace it with a new part, but we will provide suggestions using all possible methods.
