JCB Teletruk Service Manual – Complete Workshop Repair Guide

This is the complete JCB Teletruk Service Manual, the same comprehensive workshop guide used by professional technicians to maintain, repair, and diagnose the JCB Teletruk telescopic lift truck. Covering every major system on both Diesel and LPG models, this manual provides the procedures, torque values, specifications, and diagnostic information needed to keep the machine running at peak performance. Whether you are servicing a machine for routine maintenance or tackling a major hydraulic or transmission repair, this JCB Teletruk workshop manual gives you the step-by-step guidance and technical data you need.

The JCB Teletruk is a specialised telescopic lift truck designed for material handling in confined spaces. Its hydrostatic transmission, telescopic boom, and optional 4-wheel drive system make it a capable machine, but they also demand correct maintenance and repair procedures. This JCB Teletruk repair manual covers all of it, from the basic safety notices through to the advanced electronic transmission calibration procedures.

Identification and Torque Settings

The manual opens with the Vehicle Identification Number (VIN) location and decoding, allowing you to positively identify the exact machine you are working on. The torque settings chapter provides comprehensive tables for UNF Grade ‘S’ bolts and Metric Grade 8.8 bolts, covering sizes from 1/4 inch through to 1-1/2 inch and M5 through M36. Values are given in Nm, kgf m, and lbf ft, with clear notes on dry versus lubricated threads and the requirement to use only high-tensile bolts.

Service Tools and Sealing Compounds

A detailed numerical list of service tools is provided, covering body and framework tools, electrical test equipment, and hydraulic test equipment. This includes specialised items such as the AVO Test Kit, hydraulic circuit pressure test kits, flow monitoring units, and hand pump equipment. The sealing and retaining compounds section lists the full range of JCB-approved threadlockers, retainers, sealers, and activators, with their part numbers and intended applications.

Safety Notices

Every service manual begins with safety, and this one is no exception. The safety notices section covers the signal words (DANGER, WARNING, CAUTION), general safety requirements, operating safety, and maintenance safety. Specific hazards such as raised attachments, hydraulic fluid injection, electrical circuits, and battery handling are all addressed with clear warnings and first aid information.

Maintenance and Service Schedules

The maintenance section provides the complete service schedule for the Teletruk, broken down by running hours (250, 500, 1000, and 2000 hours). It covers the engine, transmission and axles, hydraulics, electrics, body and framework, and paintwork. Each service point is listed with the required action, whether it is a check, change, clean, grease, or adjust. The fluids, capacities, and lubricants table gives the exact quantities and specifications for engine oil, hydraulic fluid, coolant, and fuel.

Greasing and Lubrication

The greasing section explains the five separate greasing zones on the Teletruk: the carriage, boom, rear steer axle, sideshift mechanism, and boom pads runway. Each zone has its own diagram with numbered grease points, and the manual details the correct greasing procedure, including the use of JCB High Pressure grease and Waxoyl for the boom runways. This is critical for maintaining the machine’s working life and preventing premature wear.

Hydraulic System

The hydraulic system chapter covers fluid level checks, leak detection, hose and pipework inspection, and filter removal and replacement. It includes important safety warnings about high-pressure hydraulic fluid and the correct procedures for releasing residual pressure before working on the system. The manual also covers the hydraulic tank drain and flush procedure.

Engine Maintenance

Engine maintenance is covered in detail, including air filter element replacement, cooling system coolant mixtures and level checks, engine oil level checks and oil/filter changes, and fuel system maintenance for both Diesel and LPG engines. The Diesel fuel system section covers fuel types, tank filling, sedimenter draining, and bleeding the fuel system. The LPG section covers tank filling, tank changing, and the specific safety precautions required when working with LPG fuel.

Transmission and Drive

The transmission chapter covers the steer spindle inspection for 4-wheel drive models. The manual then moves into the more advanced transmission systems: the Torque Convertor Response (TCR) system and the Intelligent Transmission (IT) system. The TCR section covers the Susmic controller, diagnostic LEDs, and sensor/actuator replacement procedures for the throttle cable, control valve, speed sensor, brake pedal, and parking brake switch. The 4-wheel drive option section covers the speed sensor removal and replacement.

Attachments and Quick Release Couplings

The attachments section covers the flat face quick release couplings used to connect hydraulic attachments, with detailed procedures for connecting and disconnecting. It also covers fork inspection and replacement, bucket removal and replacement, and the Quickchitch system for engaging and disengaging shovels and attachments. The fork inspection section includes critical wear limits and alignment tolerances.

Access Procedures for Maintenance

This section provides the procedures for opening and closing the cab, raising and lowering the Teletruk, removing and refitting the front cover, removing and replacing the cab, and removing the operator’s seat. It also covers direct glazing procedures for removing broken glass and installing new glass, including the tools required and the step-by-step process for preparing the frame aperture, preparing the new glass, and installing it with polyurethane adhesive.

Component Removal and Replacement

The manual covers the removal and replacement of major components including the counterweight, diesel fuel tank, hydraulic tank, carriage, and boom. Each procedure includes the necessary safety warnings, lifting equipment requirements, and step-by-step instructions with references to the relevant diagrams.

Electrical System

The electrical section is extensive, covering the 12-volt DC system, bulb specifications, fuse and relay layouts for different serial number ranges, and test methods using a multimeter. It includes full wiring schematics for Diesel and LPG engines, single and twin pedal configurations, and different serial number ranges. The battery section covers specific gravity testing, battery testing with the JCB battery tester, and fault diagnosis. The alternator and starter motor sections cover charging tests, starting circuit tests, removal, and replacement.

Load Moment Indicator (LMI)

The Load Moment Indicator system is covered in detail, including adjustment using a known test weight, adjustment using an unknown test weight, testing procedures with the LMI test box, and sensor removal and replacement. This is a critical safety system on the Teletruk, and the manual provides the full calibration and testing procedures.

Torque Convertor Response (TCR)

The TCR section provides a complete overview of the system, including the Susmic controller, diagnostic LED error codes, and the sensors and actuators that make up the system. It covers removal and replacement procedures for the throttle cable (Diesel and LPG), control valve, pulse pickup (speed sensor), brake pedal, and parking brake switch. The 4-wheel drive option speed sensor is also covered.

Intelligent Transmission (IT)

The Intelligent Transmission section covers the Susmic controller – Psion communication system, including loading the Psion with JCB-supplied software, running the link program, connecting the Psion to the Susmic controller, and using the Psion-Susmic communicator. It provides detailed procedures for sensor set-up, calibration (throttle pedal, brake pedal, lift valve, engine actuator, EDC minimum), parameters menu (vehicle type, engine type, type of driving controls, driving characteristics), and time adjustments menu (auxiliary fixed RPM, lift maximum RPM, EDC forward/reverse current limits). The sensor check procedures are also included.

Why This Manual Matters

The JCB Teletruk is a sophisticated piece of material handling equipment. Its hydrostatic transmission, electronic controls, and telescopic boom require correct maintenance and repair procedures to operate safely and reliably. Using the wrong torque values, skipping calibration steps, or ignoring safety warnings can lead to expensive damage, reduced machine life, or serious injury. This manual gives you the correct procedures, the right specifications, and the safety information you need to do the job right.
