Caterpillar GP15K MC Forklift Service and Schematic Manual (99719-61120)

This Cat GP15K MC is a gasoline/LPG counterbalanced forklift for moving pallets and loads around a warehouse, plant, or yard. The service manual is for the mechanic fixing the truck, setting maintenance work, and getting it back on the rental line. In my experience, this is the book you reach for when the hour-meter service is due or a machine has a hydraulic, electrical, drive, or engine fault.

What this manual helps you do

• Trace wiring and electrical faults using the truck schematics.
• Check and adjust hydraulic, brake, steering, and power-train systems.
• Follow removal and installation procedures for major truck assemblies.
• Diagnose operating problems through workshop troubleshooting steps.
• Rebuild or service the mast, forks, axles, transmission, and related systems.

Who this is for

This suits a rental fleet mechanic, warehouse maintenance tech, dealer technician, plant maintenance team, or independent forklift repair shop. It is a workshop service manual for the Cat GP15K MC trade, with the operator handbook and related engine service information available as companion volumes.
