Caterpillar GC28N Forklift Service Manual (99719-6C130)

This Cat GC28N is a cushion-tyre gasoline/LPG counterbalanced truck for moving pallets around a warehouse, loading areas, and plant floors. When one is parked in an aisle on second shift, a warehouse maintenance tech or forklift mechanic uses the service manual to find the fault, repair the system, and get the truck back before the next wave. I've used manuals like this for breakdown work, planned repairs, and rebuilding assemblies.

What this manual helps you do

• Trace electrical faults through wiring and control circuits.
• Check and adjust steering, braking, hydraulic, and power-train systems.
• Follow removal, inspection, repair, and reassembly procedures.
• Diagnose drive, mast, fork, and hydraulic complaints.
• Verify service data while repairing the truck and its K25 engine.

Who this is for

This suits warehouse maintenance technicians, dealer technicians, independent forklift repair shops, plant maintenance teams, and rental fleet mechanics working in the forklift service trade. The operator handbook and companion chassis or engine volumes are also available where a job calls for that neighboring reference.

FAQ

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

A: You receive a set of two Cat publications supplied as 24 PDF files split by section, with 687 pages total. The files carry a real text layer, so you can search and copy text, as well as print or zoom the pages.

Q: Which trucks and serials does it fit?

A: It covers GC20N, GC25N, GC28N, GC30N, GC33N, and K25, with GC28N serial coverage AT83F-10121 to 30120. That gives you a clear match point before starting repair work.

Q: How does it fit the job?

A: It is a workshop service reference for fault-finding, adjustments, component repair, and engine or truck assembly work. It is the kind of book you reach for when a used truck arrives without documentation or a breakdown needs handling in-house.

With this set, you can diagnose the GC28N, carry out repairs, and return the truck to service with the workshop information in hand.
