Caterpillar GC25K Forklift LPG Service Manual (99719-80150)

On a real warehouse floor or yard, a Cat GC25K moves palletized loads through daily loading, storage, and production work. Warehouse maintenance technicians, dealer technicians, and independent forklift shops reach for this manual when they need to service the truck by the book, with procedures, service data, and fault diagnosis in front of them. This is the LPG fuel-system supplement for the engine service manual, covering the converter, regulator, mixer, tank, and LPG lines.

What this manual helps you do

• Trace LPG fuel flow from the tank through the lines, converter, regulator, and mixer
• Check fuel-system components during scheduled service and fault diagnosis
