Caterpillar GC30K Forklift LPG Service Manual (99719-80150)

A Cat counterbalanced truck moves pallets, loaded skids, and materials around a warehouse, plant, or yard. This manual is for the mechanic tracing an LPG fuel fault, servicing the gas system, or getting a truck ready for its next shift. I've found this kind of book most useful when hour-meter service is due and the machine can't afford surprises. The LPG fuel system is covered here as a supplement to the matching engine service manual.

What this manual helps you do

• Trace LPG fuel flow from the tank and lines through the converter, regulator, and mixer.
• Check and adjust the LPG components during scheduled maintenance.
• Diagnose starting, running, fuel delivery, and mixture problems.
• Rebuild or replace serviceable LPG fuel-system parts using workshop procedures.
• Verify repairs before returning the truck to warehouse or yard duty.
