Professional Caterpillar Gas Generator Service
Caterpillar gas generator sets are designed for long service life with planned maintenance. Top-end and major overhauls are planned on the engine model, rating, fuel consumption and running hours — not guesswork.
We follow that approach: we track your running hours and condition, use oil analysis and inspection to time the work, and carry out top-end, in-frame and major overhauls, ignition and control repairs, and full load testing after the job.
