Terex TA30 Tier 3 Articulated Dumptruck Maintenance Manual SM859 – Full Workshop PDF

Description

Terex TA30 Tier 3 Articulated Dumptruck Maintenance Manual — SM859 / 15501359

This is the complete Terex TA30 (Tier 3) Articulated Dumptruck Maintenance Manual, published under document number SM859 and part number 15501359. It is the same workshop-grade reference used for scheduled servicing, component removal and installation, and system diagnosis on the Cummins QSM11-powered TA30. Every exploded view, torque figure, pressure setting and step-by-step procedure from the factory publication is reproduced here in a single, print-ready PDF.

If you own, operate, service or repair a Terex TA30 Tier 3 dumptruck, this manual is the practical companion to the machine itself. It documents the whole vehicle — from the Cummins QSM11 engine and ZF 6WG 310 transmission through the three axles, hydraulic braking system, body hoist and electrical network — in the level of detail only a manufacturer maintenance manual provides.

000 General Information

Opens with machine dimensions diagrams (SAE turning radius, clearance radius, tail chute angle), followed by the full specifications for the Cummins QSM11 engine, ZF 6WG 310 RPC transmission, three-axle permanent all-wheel-drive layout, suspension, wheels and tyres, hydraulic system, brakes, steering, body hoist, electrical system, body construction, service capacities, noise levels, vehicle weights and ground pressures. It is the reference chapter every technician needs before touching the machine.

100 Chassis

Covers the front and rear frame assemblies, articulation and oscillation pivot, hood and mounting. Includes the general arrangement of the frames, inspection and straightening, frame reinforcement, welding procedures with pre-heat and post-heat temperatures, plus a full exploded view of the articulation pivot with nylon bushes, thrust nut, bearings, seal housings and shims.

110 Engine

Details the Cummins QSM11 four-cycle turbocharged diesel with air-to-air charge cooling and electronic management. Includes engine mounting, front and rear mounts, isolation mounts, alternator and fan belt adjustment, the Quantum Electronic Fuel System (ECM, PROM, injectors, electronic foot pedal), the engine protection derate system, diagnostic fault codes, maintenance monitor reset, engine removal/installation, and routine service intervals with torque figures.

120 Transmission

Devoted to the ZF 6WG 310 RPC automatic transmission with manual override and integral hydrodynamic retarder. Includes the EST-37 automatic shift control, the VTS-3 shift controller operation, lockup clutch, gear selection, speedometer sensor, differential pressure switch, differential locks, retarder control, diff-lock/retarder valve, speed sensors, temperature sensors, solenoid coil ratings, AEB Starter calibration and a comprehensive fault code table with TCU reaction and checks.

130 Drivelines

Front and rear drivelines, universal joints, slip joints, anti-flail guards and mounting. Includes removal, disassembly, inspection, assembly, installation and a driveline diagnosis chart for vibration, noise and excessive wear.

140 / 150 / 160 Axle Groups

Front, centre and rear axle groups together: differential drive head, axle group (hub), planetary and wheel, wheel rim and tyre. The centre differential, front and rear differential and limited slip cross-axle differential are all shown as full exploded views, together with pinion pre-load, backlash, ring gear run-out and Gleason gear tooth contact patterns.

165 Brake Parts & 170 Parking Brake

Rear brake parts, front brake parts and the parking brake with its mounting. Covers the calliper disc-type service brakes, brake pad removal and installation, pad burnishing procedure, brake head assembly and bleeding the braking system. The parking brake section details the sliding calliper, spring-applied/hydraulically released actuator, slack adjuster and clearance adjustment.

180 Suspension System

Front and rear suspension. The front axle is carried on the leading arms of a sub-frame pivoting on the main frame; the rear axles are coupled by rubber-bushed control links with equaliser beams and interleaf mounts. Includes full exploded views, torque tables, shim calculations and lubrication intervals.

190 Electrical System

Circuit diagrams, component designations (A, B, E, G, H, K, L, M, N, P, R, S, Y prefixes), fuse and relay locations, terminal designations to DIN 72 552, wire colours, and the IQAN TOC8 hydraulic ECU with its inputs, outputs, error codes and pin connections. Essential for anyone tracing a fault in the machine’s 24 V system.

200 Fuel System

The Quantum Celect Plus electronic fuel system: fuel tank and mounting, fuel filter/water separator, fuel pump, ECM cooling plate, electronic unit injectors, fuel lines and diesel fuel oil quality requirements, with removal, disassembly, assembly, installation and troubleshooting air leaks in fuel lines.

Who This Terex TA30 Manual Is For

This Terex TA30 Tier 3 maintenance manual is written for the fleet technician, the independent heavy equipment mechanic, and the owner-operator who wants to keep a TA30 running to schedule. It supports the full range of work: routine servicing and lubrication, component removal and installation, differential and axle rebuilds, transmission diagnostics and fault-code reading, hydraulic valve servicing, brake and accumulator work, and electrical fault tracing. The torque tables, pressure settings and exploded views mean the job can be done to the manufacturer’s figures rather than guessed at.

Why It Matters

A 28 000 kg payload articulated dumptruck is unforgiving of guesswork. A pinion set with the wrong backlash, a steering cylinder torqued short, a brake accumulator under-charged, or a transmission fault code ignored can all lead to premature failure and costly downtime. Because every procedure, clearance, torque value, pressure setting and diagnostic code in this manual is taken directly from the Terex factory publication, you are working to the same data the dealer uses. That is what makes a proper Terex TA30 SM859 maintenance manual worth having on the workshop laptop.
