A look behind the scenes: a normal day of compressor and engine work in our workshop.
Removing rust and contamination from a compressor fuel tank with laser cleaning instead of chemicals.
Injector replacement on a Caterpillar C7 engine — removal, cleaning of the seats and refitting.
Dismantling the fuel tank of an Atlas Copco generator with a Cummins engine for cleaning and repair.
Did you know that when removing injectors from Mercedes/MTU Friedrichshafen or Detroit Diesel Series 60 engines, the copper injector cups get stuck in the cylinder head and simply won't come out?
Working with the ECU connectors and wiring harness of a Scania engine — diagnostics and correct pin handling.
We are disassembling the Atlas Copco QES 60 generator with a Cummins engine because we need to remove the fuel tank. We work quickly because the customer asked us to return the generator. All fluids are drained from the Cummins engine — coolant, engine oil and diesel fuel. The control panel is disconnected from the generator, then all cable harnesses, the radiator and the diesel fuel heater. In the video it doesn't look like very tedious work.
Service work on a mobile air compressor with a Deutz diesel engine.
The compressor element seal is leaking, so we had to pull out the Deutz engine and separate the compressor unit from the motor.
How the copper cups behave when injectors are pulled out of MTU and Mercedes engines, and how to get them out safely.
There is little difference between the injectors of the MTU and Mercedes OM4x series engines, so we decided to swap the injectors between these engines to find out whether they are interchangeable.
A closer look at a high-pressure Atlas Copco XAHS 347 portable compressor on site.
Our client asked us to clean the fuel tank because dirt had accumulated in the diesel tank. To do this we had to completely disassemble the compressor and pull out the motor and generator. This work took us 3 days.
