Caterpillar GC25K HP Forklift LPG Service Manual (99719-80150)

This Cat GC25K HP is a counterbalanced LPG forklift for moving pallets and materials around a warehouse, plant, or yard. Warehouse maintenance technicians and forklift shops use the service manual when they need to repair the truck by procedure, verify settings, and document the work. This publication covers the LPG fuel system, including the converter, regulator, mixer, tank, and fuel lines. It pairs with the engine service manual, as Caterpillar published the engine and LPG information together as separate workshop references.

What this manual helps you do

• Trace LPG fuel-system faults, leaks, and supply problems.
• Check and service the converter, regulator, mixer, tank, and lines.
• Follow removal, inspection, adjustment, and installation procedures.
• Diagnose running and fuel-delivery complaints during workshop repairs.
• Verify service work by the book for planned maintenance and warranty records.

Who this is for

This suits warehouse maintenance technicians, dealer technicians, independent forklift repair shops, plant maintenance staff, and rental fleet mechanics. It is written for the forklift repair trade, with the companion chassis and mast manual also available for the rest of the truck.
