GRAND MASTER

Heavy-duty trucks that transport large loads every day require special care for the fuel system’s condition.
At Grand Master, we offer comprehensive diagnostics and repair of injectors, unit injectors, injection pumps (e.g., Common Rail, inline pumps), and other critical fuel system components in trucks.
We service popular truck brands such as Mercedes-Benz, MAN, DAF, Scania, Iveco, Volvo, Renault, Nissan, Tatra, Mitsubishi, and many others.

Construction and special machinery — such as excavators, bulldozers, cranes, and others — often operate in harsh conditions. That’s why fuel system reliability is especially important.
At Grand Master, we carry out professional diagnostics and repair of injectors, unit injectors, injection pumps (e.g., Common Rail, inline pumps), and other fuel system components for construction and special machinery.
We service popular brands like Caterpillar, Volvo, JCB, Bobcat, Hitachi, Builder, Case, and many others.

Passenger cars also require regular inspection and maintenance of the fuel system. Proper functioning of injectors and injection pumps ensures smooth engine operation, optimal fuel consumption, and helps minimize harmful emissions into the environment.
At Grand Master, we offer complete diagnostics and repair of injectors, unit injectors, injection pumps, and other essential fuel system components for passenger cars.
