Caterpillar GC35K Forklift Engine Service and Schematic Manual (99739-82110)

A Cat GC35K is a counterbalanced truck used to move and stack loads around a warehouse, plant, or yard. When the engine needs testing, adjustment, teardown, or rebuild work, this is the workshop manual a maintenance technician or repair shop reaches for. It gives the engine procedures and service data needed to do the job by the book, including work that may be checked during an audit.

What this manual helps you do

• Check engine specifications, service intervals, operating systems, and fault symptoms.
• Trace engine-related wiring and schematics while diagnosing starting, charging, and control problems.
• Follow testing and adjusting procedures, including torque values, clearances, and service checks.
• Rebuild engine assemblies with disassembly and assembly instructions in the proper order.
• Verify repairs with the specified inspections and operating tests.

Who this is for

This suits warehouse maintenance technicians, plant maintenance staff, rental fleet mechanics, dealer technicians, and independent forklift repair shops. It is the engine book of the set, while chassis, mast, hydraulic, steering, and truck systems are covered in the companion chassis manual, also available. That's the normal Cat manual arrangement.
