Rebuilding a Clark GPX 35, 40 or 50E forklift without calling the dealer is the job this 411-page service manual PDF is built for, running from engine removal through uprights and counterweights. The electrical chapter pairs a wiring color code with wiring diagrams, while the lift circuit section ends on a hydraulic schematic tracing oil from the sump and pump through the control valve to the lift and tilt cylinders. Transmission overhaul fills one of the thickest chapters in the book, and troubleshooting charts for cooling, brakes, steering and uprights help you narrow a fault before anything comes apart. Keep LPG fuel lines at least 2 in. (50,8 mm) clear of exhaust parts, and torque connecting rod nuts to 27 N·m (20 lb. ft.) plus a 70° turn. A mast that creeps under load can eat a shift. With bookmarked chapters and a text layer you can search, you confirm the exact component and your nameplate data before ordering parts.
