Caterpillar Diesel Generator Repairs
People search both Caterpillar and CAT. This is the one page for those diesel generator sets. There is no second CAT URL.
The work is commercial standby and industrial sets. A plant generator and an office standby set are not the same visit even when the badge matches.
Caterpillar Diesel Generator Servicing
Planned maintenance is oil, filters, coolant, batteries and a transfer test where an ATS is fitted. ProService Generator Repairs is not a CAT dealer.
Caterpillar Diesel Generator Sizes We Service
Supported Caterpillar diesel generator sets are worked on across the capacities that match the machine on site, from the applications described above through to larger sets where the plate and the installation allow it. Engine, alternator, controller, kVA, phase, duty, hours and service history decide the work. A maximum kVA is not stated.
Why a Caterpillar diesel generator will not start
A CAT set that will not start is split the same way as any diesel: no crank versus crank with no fire. Emergency stop, low coolant and low oil are checked before the starter is replaced.
Fuel system, cooling and output
Fuel filters, lines and injection delivery are confirmed on the engine in front of the technician. Calibration steps are not published for customers to try.
Radiator blockage and a slipping belt show up as temperature shutdowns on long runs. Controller and AVR work stays separate from the engine service.
Common Caterpillar Diesel Generator Faults
Checked on the set. The finding decides the repair.
Cranks, no fire
Fuel filters, air, a solenoid or injection delivery — proved in that order.
Runs, no power
Breaker, AVR and alternator after the diesel is stable.
Shuts down on load
Temperature, oil pressure or a controller trip. The alarm is read before a reset.

Frequently Asked Questions About Caterpillar Diesel Generators
Do you repair Caterpillar and CAT diesel generators?
Yes. Caterpillar and CAT diesel generator sets are repaired on this one page. People use both names. ProService Generator Repairs is not a CAT dealer. Starting, fuel, cooling, controllers and output are diagnosed on the installed set.
Do you service CAT standby generator sets?
Yes. Planned servicing covers oil, filters, coolant, batteries and a transfer check where an ATS is fitted. A set that only runs for a few minutes on test still needs the fuel and the cooling pack looked at.
Why won't my CAT generator start?
A CAT generator may not start because of a flat battery, a starter fault, an emergency stop, low coolant, low oil or a controller inhibit. The first split is whether it cranks. Fuel is the next check when it cranks and will not fire.
Can you diagnose Caterpillar generator controller alarms?
Yes. The alarm text is photographed and diagnosed. Codes are not guessed from a different model. A shutdown for temperature or oil pressure is not cleared by resetting the controller and trying again.
Do you repair CAT generator voltage faults?
Yes. Low, high or missing voltage is checked after the engine holds speed. The breaker, AVR and alternator are separate from the Caterpillar engine service and are quoted that way.
Can you investigate overheating on Caterpillar generators?
Yes. Temperature shutdowns on long runs are often a blocked radiator, low coolant, a slipping belt or poor airflow. The cooling fault is confirmed before a thermostat or water pump is replaced.
Do you service commercial and industrial Caterpillar generators?
Yes, where the installation can be taken on. An office standby set and a plant generator are not the same visit. The kVA is read on site. A maximum is not published.
