Description

DAF LF45 LF55 Truck Service Repair Workshop Manual

This extensive DAF LF45 LF55 Truck Service Repair Workshop Manual PDF brings together detailed technical information, diagnosis, inspection, adjustment, removal, installation, disassembly and assembly procedures for major LF45 and LF55 vehicle systems. At 2242 pages, it is a substantial workshop reference covering the truck from cab equipment and chassis components through engines, transmissions, braking, steering and electrical systems.

The manual is arranged as a series of technical groups rather than a brief maintenance booklet. Individual systems include their own technical data, tightening torques, diagnostic material, component descriptions and illustrated repair procedures where applicable. Numerous drawings identify assemblies, connections and component positions, while fault-finding tables help trace faults before parts are removed unnecessarily.

Vehicle and Workshop Reference Information

The opening technical material establishes vehicle configurations and workshop practices used throughout the DAF LF45/55 repair information. Vehicle-model diagrams identify FT/FA 4 x 2 and FAN 6 x 2 arrangements, including steered and driven axle positions. General workshop sections cover locking compounds and sealants, standard threaded connections, tightening methods, seals, bearings, preservation, cleaning, paint treatment and unit-conversion tables.

These sections are useful when a repair extends beyond simply removing a component. The manual explains correct treatment of reusable threaded connections, application of locking and sealing compounds, bearing installation, conventional and unitised seal handling, and the precautions required when working around batteries, pressurised systems, wiring harnesses, welding operations and cab-tilting equipment.

Cab Components, Heating and Cab Tilting

The cab material goes well beyond trim removal. It covers internal and external cab components, steering-column assemblies, dashboards, door panels and window mechanisms, roof console and lining, door locks, mirrors, windscreen and rear-window installation, headlights and wiper equipment. Cab dimensions and weights, suspension mounting data and specified tightening torques are included alongside the procedures.

Heating and ventilation coverage includes the heater unit, interior filter, heater control panel, heater motor, series resistor and heater radiator. The cab suspension and hydraulic tilting sections explain front and rear suspension arrangements, cab supports, silent blocks, locking mechanisms, lifting cylinder and cab-tilting pump. Illustrated pump disassembly identifies individual components including the reservoir, plunger, valve block, seals, O-rings, direction selector and pump housing. Diagnostic tables address faults such as a tilting cylinder that fails to respond, a pump that does not build pressure and a cab that cannot be tilted.

BE and CE Engine Systems

Dedicated engine groups cover the BE engine and CE engine, together with their cooling and lubrication systems. The manual provides technical data and workshop operations for engine-related service, inspection and repair, supported by system drawings and tightening specifications. Lubrication procedures include draining and replenishing engine oil and work on lubrication-system components.

Separate fuel-system groups describe the ECS-DC3 system used with BE and CE engines. The information follows fuel from the tank through the electronic-unit cooling plate, lift pump and fine filter to the high-pressure pump and fuel rail. It identifies the rail-pressure sensor, pressure-limiting equipment, injector supply and return components, and the fuel-pump control solenoid. The manual also contains component descriptions and illustrated procedures for working on these systems rather than merely providing a component list.

Inlet/exhaust and engine-brake material is also included. Engine-brake procedures cover the exhaust brake, its operating cylinder and associated air connection, with inspection, adjustment and removal/installation information.

Gearboxes, Clutch and Driveline

Transmission coverage is unusually broad. The DAF LF45 LF55 workshop manual includes both mechanical and pneumatic gearbox controls plus dedicated information for the ZF S5-42, ZF 6S-850, Eaton FS/6309A, Allison 1000 & 2000 automatic gearboxes and Allison MD 3060 automatic gearbox. Depending on the gearbox, sections include system descriptions, component construction, checks, adjustments, removal and installation, disassembly/assembly, oil draining and filling, capacities and tightening specifications.

The manual describes the five-speed ZF S5-42 and six-speed ZF 6S-850 gearbox arrangements, including synchroniser construction. Clutch data identifies MF 362 and MF 395 clutch release assemblies in the applications listed in the manual, and the driveline section covers Spicer and Monotron prop-shaft arrangements with their applicable fastening data and service procedures.

Braking System

A substantial brake section contains technical data, diagnostics, brake diagrams for the fully pneumatic brake system, descriptions of brake-component operation, brake-system service procedures and braking-performance information. The material is designed to support both component repair and system-level troubleshooting, including pneumatic circuitry and brake equalisation checks.

Where diagnosis is required, the manual provides fault-oriented information rather than relying only on disassembly instructions. Brake pressure relationships, pneumatic system operation and component interaction can therefore be checked before proceeding with repairs or adjustments.

Steering, Front Axles and Rear Axles

The steering section covers multiple LF45 and LF55 configurations. Technical information includes ZF 8090, ZF 8095 and ZF 8098 steering boxes and ZF 7684, ZF 7685 and ZF 7687 steering pumps where specified for the relevant vehicle versions. Procedures address steering-system inspection, steering-box and pump work, filling and bleeding, leakage checks and correct tightening of steering connections.

Front-axle coverage includes F36, F48, F60 and 152N axle material plus the steered trailing swivel axle. Illustrated sections identify wheel-hub, swivel-axle and king-pin related parts and support inspection and component replacement work. Rear-axle information includes single rear axle types 5.10, 5.12, 5.14, 8.20, 10.20, 10.26 and 11.26, with technical data, filling capacities and service information for the applicable assemblies.

Suspension and Chassis-Related Work

Suspension material covers shock absorbers, stabilisers, torque rods and leaf or air-suspension arrangements used across the LF45/55 series. The manual provides specified dimensions and fastening values for relevant configurations and distinguishes between LF45, LF55 and FAN applications where the procedures or specifications differ.

Cab suspension is treated separately because of its relationship with cab alignment and the hydraulic tilting system. Procedures include replacing spring elements, rubber supports and silent blocks, removing cab locks, checking cab height and removing or installing the complete cab.

Electrical System, Wiring and Diagnostics

The electrical portion of the DAF LF45 LF55 Service Repair Manual contains component technical data, diagnostic guidance, wiring repair, batteries, accessory connections, diagram-reading instructions, component locations, connector locations and the vehicle electrical system. Circuit diagram 1427090/03 is accompanied by basic-code information, connector and pin-allocation references and numerous section diagrams. A later electrical-system section records changes from chassis number 0L247507 and references circuit diagram 1427090/04.

Wiring-repair chapters explain connector and contact handling, fitting contacts to electrical wires, SCAT seals, electrical buffer connections, earth wiring and CAN-network wiring repair. The diagnostic information also describes the use of DAVIE XD for electrical diagnosis, measurements and guided fault tracing.

Accessory-connection material includes reserve wiring, dashboard lead-through connectors, superstructure-function application connections, engine-speed-control connections, automatic gearbox application connections and radio/roof-console wiring. This makes the manual useful when repairs involve the interface between the standard vehicle harness and fitted equipment.

Repair With the Correct Procedures and Technical Data

A DAF LF45 or LF55 can involve several different engines, transmissions, axle arrangements and cab configurations, so having the correct procedure and specification beside the job is especially valuable. This 2242-page DAF LF45 LF55 Truck Service Repair Workshop Manual PDF gives technicians and owners a single detailed reference for diagnosing faults, dismantling and assembling components, checking adjustments, following tightening requirements, tracing wiring and understanding how the vehicle’s major systems operate.

Whether the work involves a BE or CE engine system, ZF or Eaton manual transmission, Allison automatic gearbox, clutch, braking system, steering gear, axle, suspension, cab equipment or electrical fault, the manual provides the system-specific information needed to approach the repair methodically instead of relying on guesswork.
