№636289 Repair of trucks and special equipment

Half the battle is knowing what's broken. The other half is fixing it properly. Modern equipment talks in error codes, warning lights, and strange noises. Most shops see flashing lights and start replacing expensive parts. We plug in diagnostic equipment first and let the machines tell us what's wrong. Specialized machinery diagnostics isn't guesswork. These machines have computers that record everything - engine performance, hydraulic pressures, electrical faults, operating temperatures. The trick is knowing which data matters and which is just noise. Take hydraulic problems on excavators. Could be pump failure, contaminated fluid, worn seals, or electrical issues with control valves. Symptoms look similar, but fixes are completely different. Proper diagnosis saves time and money.
