CLARK GPX / DPX 30–55 Forklift Service Manual

The CLARK GPX / DPX 30, 35, 40, 40S, 50 & 55 Service Manual is a comprehensive workshop reference designed for servicing and maintaining CLARK industrial lift trucks. The sample manual is identified as SM 593 and provides structured service information arranged by component groups and sections.

The manual begins with important safety and planned maintenance procedures. It explains safe maintenance practices, inspection procedures and recommended checks before and during service work. The planned-maintenance section covers visual inspections, forks, wheels and tires, braking and inching systems, functional tests, steering, controls, engine-compartment checks, lubrication and lift-chain maintenance.

Detailed Workshop Service Information

The manual is organized into dedicated service groups covering the major systems of the forklift. According to the contents pages, technicians can find information for engines, cooling systems, fuel systems, transmission, electrical systems, drive axle, wheels and tires, braking/inching system, steering, steer axle, hydraulic systems, tilt cylinders, uprights and counterweights.

The engine section includes engine removal and replacement together with separate workshop information for gas/LPG and diesel engines. The cooling and fuel-system sections provide procedures for cooling-system testing and maintenance, radiator removal, fuel-pump pressure testing, carburetor overhaul, velocity governor overhaul and IMPCO vaporizing-system service.

Hydraulic, Lift & Chassis Maintenance

For the forklift’s hydraulic and lifting systems, the manual covers hydraulic sump and filter service, hydraulic pump troubleshooting and overhaul, hydraulic system pressure checks, hydraulic valve overhaul, hydraulic schematics and tilt-cylinder procedures. The upright section includes troubleshooting, operational checks, carriage and upright adjustment, cylinder repair, lift-chain maintenance and upright removal and replacement.

Maintenance information also covers drive axle service, differential overhaul, steer axle components, steering-cylinder removal, wheel bearings, braking components, master-cylinder and power-booster overhaul, brake-caliper service and parking-brake procedures.

Planned Maintenance & Inspection

The sample pages demonstrate detailed planned-maintenance procedures for daily and periodic inspection. Topics include battery condition, engine oil, engine cooling system, air cleaner, hydraulic fluid and filters, transmission fluid, chassis lubrication, steering components, critical fastener torque checks and lift-chain inspection.

The lift-chain section provides inspection and measurement guidance, including checks for rust, corrosion, cracked plates, raised or turned pins, tight joints and worn pins or holes. It also discusses lubrication, chain adjustment and replacement criteria.

Useful Workshop Reference

Illustrations and diagrams throughout the manual help technicians identify components and understand service procedures. The pictorial index identifies major component groups, while the technical sections provide step-by-step maintenance and repair information.

This digital manual is suitable as a workshop reference for technicians, mechanics, service personnel and owners working with the covered CLARK GPX and DPX forklift models.
