Engine, Fuel and Powertrain Service

A substantial portion of this Clark C60 C70 C75 C80 D and C60 C70 C75 L service manual is devoted to the different power units and driveline arrangements represented in the document. Diesel engine material includes IVECO coverage with general specifications, lubrication and cooling layouts, mechanical rotary-pump fuel injection, engine disassembly and assembly, injection-pump timing, troubleshooting, maintenance planning, overhaul dimensions, tightening torques, special tools and engine replacement. The manual identifies the IVECO F4GE9454C Tier 3 engine in its truck specifications and gives detailed service data for its related systems.

Separate Kubota engine material covers the V3800DI-T-E2B Tier 2 and V3800DI-T-E3B Tier 3 engines. This portion includes specifications, maintenance checks, engine mechanisms, servicing and troubleshooting. The LPG portion contains extensive GM V6 4.3L engine and fuel-system information, including engine removal and replacement, repair procedures, cooling-system work, LPG controls, maintenance, tests, adjustments and diagnostic material. This makes the manual useful when the exact powertrain version of the truck must be identified before service work begins.

Transmission coverage is equally detailed. Diesel trucks are covered with the 3WG-94EC transmission section, including transmission layout, measuring points and connections, disassembly, reassembly and removal/installation. The specification section also identifies ZF 3WG-94EC and ZF 3WG-116 transmission data. LPG trucks have their own T12313 transmission material, including clutch assemblies, regulator valve, cleaning and inspection, troubleshooting, transmission controller information and complete transmission removal and installation procedures. The specification pages identify the LPG unit as the DANA 1106T12313-200 transmission.

Maintenance, Testing and Troubleshooting

Routine maintenance is not treated as a brief checklist. The periodic-service group provides maintenance schedules, lubrication points and a planned-maintenance program. Service intervals shown in the manual range from daily or every 8-10 hours through 50-250 hours, 450-500 hours, 900-1000 hours and 2000 hours or one year, depending on the task and operating conditions. Inspection procedures cover fluid levels, leakage, fasteners, forks, carriage, upright, wheels and tires, brakes, steering, starting functions, warning systems and hydraulic operation.

The manual also includes system-specific troubleshooting rather than limiting the technician to general maintenance. Engine sections contain symptom/cause/remedy tables and diagnostic procedures. Transmission chapters provide pressure measuring points and troubleshooting information. Brake, steering, hydraulic and upright groups likewise include checks designed to isolate poor operation before parts are removed. Hydraulic troubleshooting addresses conditions such as loss of lift, tilt or auxiliary function, slow or jerky movement, overheated or foaming fluid, insufficient lift height and cylinder leakage.

Taken together, these chapters provide a technician with a system-by-system path from inspection and diagnosis to adjustment, component removal, teardown, measurement, reassembly and final testing. The document also supplies numerous sectional drawings, component layouts, hydraulic circuits, electrical diagrams, service tables, tightening values and dimensional data to support the procedures.

Hydraulic, Steering, Brake and Upright Repair Coverage

The load-handling system receives extensive coverage. The main hydraulic sump section specifies filtration, fluid service and pump work, while the control-valve chapters show the lift, tilt, auxiliary, steering and priority circuits. Separate schematics are provided for the C60-80D diesel and C60-75L LPG arrangements. The manual gives hydraulic pressure checks, valve testing and overhaul procedures alongside tilt-cylinder inspection, drift checks, removal and seal service.

Steering work extends from the steering column and gear to the steer axle, wheel bearings and steering cylinder. Brake coverage includes the service-brake system, inching linkage, bleeding, master cylinder and parking brake. The upright chapter then addresses one of the largest mechanical service areas on these trucks: rails and rollers, clearance and shim adjustment, lift cylinders, chains, forks, carriage and complete upright removal. These sections are especially useful when repair work involves several interacting systems rather than a single isolated component.

Truck Specifications and Service Data

Group 40 consolidates model-specific reference information for the Clark C60, C70, C75 and C80 range. The manual lists rated capacities of 6000 kg for C60, 7000 kg for C70, 7500 kg for C75 and 8000 kg for C80 at a 600 mm load center. It also provides truck and axle weights, gradeability data, travel speeds, turning-radius information, tire specifications and pressures, braking specifications, steering data, hydraulic capacities and pressures, transmission specifications, electrical information, engine specifications and critical fastener torques.

Examples of system data include a hydraulic sump capacity of 120 L for C60-75 and 147 L for C80, plus dedicated diesel and LPG hydraulic circuit information. Transmission specifications distinguish the diesel ZF units from the LPG DANA T12313 unit, while engine data differentiates the diesel and LPG powerplants. Using these model and system distinctions helps avoid applying a procedure or setting from the wrong configuration.
