What This Clark Forklift Service Manual Covers

The manual is organized by service group, and every group follows the same practical pattern: specifications first, then description, then troubleshooting, then the actual removal, overhaul, and installation procedures. That structure is what makes it usable both for a quick spec lookup and for a full teardown job.

Why This Manual Works for Real Jobs

What separates this Clark forklift service manual from a generic guide is that every procedure is tied to a specific model, engine platform, transmission, and service group. The diesel and LPG trucks share the same chassis and many of the same service procedures, but the engine groups, transmission groups, drive axle groups, and fuel system groups are all split into their own dedicated sections. That means when you are working on a C80 D with the IVECO engine, you are not sifting through pages of GM V6 content to find the right torque value or clearance. When you are working on a C60 L with the 3WG-94EC transmission, the Group 07 procedures are yours and nothing else is in the way.

The manual also includes the detailed pressure check points, measuring points, and connection diagrams for the transmission, the hydraulic system pressure check procedures for the control valve, the tilt cylinder drift and racking adjustment procedures, the upright roller shim adjustment tables, the chain length and tension adjustment procedures, and the full troubleshooting sections that walk through symptoms and causes for each system. The Group 13 electrical section includes complete circuit diagrams for diesel, LPG Tier 0, and LPG Tier 4 trucks, plus the instrument pod menu system, error codes, and AEB (automatic adjust clutch) functions.

If you maintain, repair, or overhaul Clark C60, C70, C75, or C80 series forklifts, whether diesel or LPG, this service manual gives you the exact procedures, specifications, and adjustments for the job you are doing. It covers everything from a routine 50-hour PM to a full engine overhaul, transmission rebuild, drive axle service, upright overhaul, and hydraulic valve repair.
