Yale B878 (GP/GDP/GLP135/155CA) Forklift Pdf Repair Service Manual

Yale B878 (GP/GDP/GLP135/155CA) PDF Repair Service Manual

When maintaining a Yale B878 forklift, the exact powertrain configuration matters. The GP, GDP, and GLP designations identify different versions of the 135CA and 155CA truck family, so engine and fuel-system service information needs to match the equipment being repaired. The Yale B878 GP/GDP/GLP135/155CA Repair Service Manual brings together workshop information for these forklift models in a convenient digital reference.

Whether your workshop is investigating an engine issue, servicing the powershift transmission, repairing hydraulic components, or working on the mast, this PDF manual helps you locate the relevant system information, procedures, diagrams, and technical specifications for the covered truck series.

Model Compatibility

Engine and Fuel-System Information for Different Configurations

The B878 model family includes different engine and fuel arrangements. The documented service sections include GM engine information, Perkins 1104-series diesel engine coverage, and electronic LPG/gas fuel-system information for applicable GM engine configurations.

• GM engine servicing: Technical information for the covered GM engine configurations and their related components.
• Perkins 1104 diesel engine: Service references for applicable diesel engine maintenance and repair tasks.
• LPG and gasoline fuel controls: Information for the electronic fuel-control systems used with applicable GM 3.0L and 4.3L EPA-compliant engines.
• Cooling system: Reference material for cooling-system components and service work.
• Ignition and electronic diagnostics: Applicable ignition-system information and engine-control troubleshooting procedures for covered GM configurations.

These separate engine sections are especially useful when identifying the correct procedure for the truck in your workshop. Before beginning engine or fuel-system work, match the manual section to the installed configuration rather than assuming that every GP, GDP, and GLP model uses the same components.

Transmission and Drivetrain Repairs

The B878 manual includes information for the two-speed powershift transmission, covering its operation as well as repair. This can help technicians follow the relevant technical references when investigating shifting concerns, inspecting transmission components, or preparing for disassembly and reassembly.

Related drivetrain coverage includes the speed reducer, differential, and drive axle. The manual also addresses the steering control unit, steering axle, and brake system, providing a broader reference for diagnosing and servicing the mechanical systems that affect forklift movement and control.

Hydraulic System and Lifting Equipment

When the problem involves lifting, tilting, or hydraulic response, the relevant service information can help narrow the work to the affected component. The documented hydraulic and lifting-system topics include:

• Hydraulic gear pumps: Service information for the pump assemblies.
• Hydraulic system: System-level technical references and component servicing information.
• Main control valve: Service material for the hydraulic control valve.
• Tilt cylinders: Information for servicing the mast tilt mechanism.
• Lift cylinders: Technical references for the lifting system.
• Mast assemblies: Mast description and repair procedures, including applicable mast configurations.
• Attachments and header hoses: Reference information for covered attachments and associated hose groups.

For technicians, having these topics together is useful when preparing a repair, identifying related components, or consulting the correct procedure during assembly. The manual also includes information for two-stage limited-free-lift and three-stage full-free-lift mast arrangements, along with other covered mast configurations.

Electrical Systems and Workshop Reference Data

Electrical faults can affect starting, engine operation, and instrument-panel indications. The B878 service documentation includes material for the alternator and regulator, starter, instrument-panel indicators and senders, and applicable electronic engine-control troubleshooting.

Additional reference sections support day-to-day workshop planning and equipment upkeep:

• Periodic maintenance procedures.
• Capacities and technical specifications.
• Metric and inch (SAE) fastener references.
• Electrical and hydraulic diagrams for covered systems.
• Service information for frame, engine, transmission, axle, steering, braking, and mast assemblies.
