Kohler 30-175 kW Industrial and Towable Generator Sets Service Manual (tp6929)

These Kohler 30–175 kW industrial and towable generator sets usually sit on construction sites, plants, or event grounds, running long hours in dust, vibration, and weather. This service manual is what I use to trace faults logically instead of guessing at parts. If a unit won’t carry load, keeps shutting down on a fault code, or has unstable voltage, this book walks you through checks, adjustments, and the right way to strip and rebuild components so you confirm the failure before you spend money.

Applications & Use Cases

• Track shutdowns and alarms step by step, so you isolate whether the issue is sensor, wiring, control, or the generator itself.
• Verify output problems by following the test procedures before touching regulators or replacing control boards.
• Disassemble and reassemble engine, alternator, and mounting hardware in the right order to avoid missed seals, shims, or fasteners.
• Adjust linkages and controls so the set carries load smoothly after a repair or component swap.
• Plan parts replacement by confirming what’s actually failed instead of shotgun-replacing assemblies.

FAQ

Q: Can I use this manual on a tablet at the jobsite?

A: Yes, it’s practical to keep it on a tablet so you can zoom diagrams and search terms while working beside the generator.

Q: Is it worth printing sections of this manual?

A: Many techs print the procedures and diagrams they use most, then keep them in a binder that can handle grease and rough handling.

Safety Note

Always lock out the generator and verify it cannot start automatically before opening any covers or disconnecting components.
