Description
JCB 506-36 to 514-56 Service Manual is the factory technical publication for the JCB Loadall 5C machine group. It covers the 506-36, 507-42, 509-42, 510-56, 512-56 and 514-56 models, identified within the manual by model codes 5CD to 5CJ.
This comprehensive 1,801-page manual is intended for professional technicians, plant engineers and workshops responsible for servicing and repairing these machines. Publication 9813/1800-2 organises information into dedicated sections covering general information, safety, routine maintenance, body and framework, electrics, hydraulics, transmission, brakes, steering, engine and electronic data systems.
JCB uses application tables throughout the publication to identify which topics apply to each model and machine variant. Technicians should therefore confirm the machine identification and applicable variant before following a procedure or specification.
GENERAL INFORMATION AND MAINTENANCE
The opening sections provide the reference information needed to identify the machine, interpret the manual and prepare for workshop operations.
- Machine and component identification plates
- Model and variant application tables
- Hydraulic schematic codes
- General torque settings
- Hydraulic connections and positional adaptors
- Service tools and tool references
- Sealing and retaining compounds
- Fuel requirements and suitability
- Stall-speed combinations and specifications
- Routine maintenance information
BODY, FRAMEWORK AND BOOM
Body and structural coverage varies by model and is clearly identified in the manual’s application tables. The listed subjects include cab equipment, exterior components, boom assemblies and selected stability or interlock systems.
- Cab heating and ventilation
- Cab air-conditioning system
- HV and HVAC units
- Air-conditioning condenser and binary switch
- Fuel tank and engine cover
- Mudguards and stabilisers
- RAS system and RAS ECU
- Machine interlock system and components
- Boom assembly
ELECTRICAL AND ELECTRONIC SYSTEMS
The electrical section supplies model-applicable workshop information for the principal power supply and wiring systems. Electronic network and electronic data system material is contained in a separate manual section.
- Fuses and relays
- Electrical schematics
- Electrical harness system
- Battery charging system
- Alternator information
- Battery servicing information
- Electronic network systems
- Electronic data systems
HYDRAULIC SYSTEM
Detailed hydraulic coverage includes system schematics, circuit operation, pressure and flow testing, fault diagnosis and component procedures. Both parallel and LSP hydraulic arrangements are identified, with application tables showing their relevance to individual models and variants.
- Hydraulic systems and schematics
- Parallel and LSP hydraulic systems
- Parallel and LSP circuit operation
- MRV, LSRV and ARV operation
- Parallel lift operation
- Boom pressure-balance system
- Flowshare servo and parallel circuit faults
- Hydraulic system pressure tests

- Flowshare and parallel control valves
- Pilot-pressure supply and servo control valves
- Extension, lift, tilt and displacement rams
TRANSMISSION, BRAKES AND STEERING
Separate manual sections are provided for the transmission, braking and steering systems. These sections support workshop servicing alongside the general specifications, safety instructions and application references supplied elsewhere in the publication.
- Transmission systems
- Brake systems
- Steering systems
- Applicable service procedures
- Model and variant references
TESTING, FAULT-FINDING AND REPAIR
The JCB 506-36 to 514-56 Service Manual includes test and diagnostic subjects for supported systems, particularly the hydraulic equipment. Information is arranged to help technicians relate symptoms and test results to the appropriate circuit or component.
- Universal hydraulic fault diagnosis
- Parallel hydraulic circuit faults
- Flowshare servo circuit faults
- Hydraulic pressure testing
- Hydraulic pump flow testing
- System and circuit operation
- Component removal and replacement
- Service-tool references
