Caterpillar GP15 MC Forklift Service Manual (99719-34130)

A Cat GP15 MC is a gasoline/LPG counterbalanced forklift used to move pallets and materials around warehouse floors, loading areas, and plant yards. The service manual is for the mechanic who has to return one to work, meet hour-meter maintenance, or find a fault before tomorrow's dispatch. I've used this kind of book for scheduled service, teardown work, adjustments, and electrical troubleshooting.

What this manual helps you do

• Trace wiring, switches, charging circuits, and starting faults.
• Check and adjust the brake, steering, hydraulic, mast, and power-train systems.
• Follow removal, inspection, repair, and reassembly procedures for major truck components.
• Diagnose operating faults using service data and troubleshooting guidance.
• Rebuild or replace engine-related assemblies using the matching engine publication.

Who this is for

This suits a rental fleet mechanic, warehouse maintenance technician, plant maintenance team, dealer technician, or independent forklift repair shop. It is a workshop service manual for the Cat GP15 MC trade, while the operator handbook is the companion volume also available for daily operating instructions.

FAQ

Q: What do I receive, and how is it organized?

A: You receive two separate Cat publications in a set, delivered as 30 PDF files split by section, with 144 pages total. The files can be printed or enlarged on screen, and the set has a real text layer for searching and copying.

Q: How does it fit the job?

A: Use it when the truck needs scheduled service, fault diagnosis, component adjustment, or shop repair. It puts the chassis and engine service information together for practical turnaround work.
