Description

Volvo EW145B Service Information Manual – Complete Deutz D6D EOE2 Workshop Reference

This Volvo EW145B Service Information manual is the full workshop reference for the EW145B wheeled excavator and its Deutz D6D EOE2 diesel engine. Published by Volvo Construction Equipment with a document date of 27/11/2019, the 373-page file organises every procedure by Volvo function group, running from the 200-series engine chapters through the 990-series hydraulic circuit diagrams. Technicians working on the EW145B get the assembly descriptions, tightening torques, measuring conditions, wiring diagrams and hydraulic schematics gathered into one reference instead of hunting through separate bulletins.

Read as a whole, this manual walks a technician through the EW145B from the bare engine casting to the complete machine circuit. The engine chapters explain the Deutz D6D EOE2 architecture – six-cylinder, four-stroke, direct-injected, turbocharged and aftercooled with a cast iron block and head – then break it down into the cylinder head gasket selection routine, cylinder liner and piston ring details, valve adjustment and IEGR hardware. Separate function groups cover the crankshaft and connecting rod, forced-feed lubrication with the rotary pump and cooler housing, the common-rail fuel system with its low-pressure and high-pressure circuits, the inlet and exhaust paths, the turbocharger, and the closed-circuit cooling system with its thermostat and coolant specification. From there the document moves to the electrical architecture: the E-ECU, I-ECU and V-ECU control units, the software parameters that can be programmed through the service tool, the general troubleshooting approach, the collection of basic data, and the PIN-level measuring conditions for each controller with the expected voltages and resistances. The power transmission function group covers the hydraulic travel drive, the transfer gearbox with its shift lock and parking brake, the swing gearbox reduction ratios and lubrication, and the travel gearbox removal and installation sequence. The 990-series chapters take the reader through the main control valve stack, the individual valve cartridges, the holding and regenerating valves, the centre bypass valve, the hydraulic pump construction and adjustment, and a full set of coloured hydraulic circuit diagrams for neutral, boom raise conflux, arm in conflux, bucket curl and travel. The 370-series wiring diagrams at the back document the machine harness section by section, from battery and alternator feeds through the lighting, wiper, air-conditioning, radio and service socket circuits, with component designations and connector pin references throughout.

Engine and Fuel System Work

For the D6D EOE2 the manual gives the full tightening torque table covering rocker arm brackets, cylinder head cover, exhaust return module, valve adjusting lock nuts, front cover, oil pan drain plug, turbocharger mounting, injector clamping shoes, injection lines, high-pressure pump, fuel control valve, rail and rail pressure sensor. The cylinder head gasket chapter explains how piston projection is measured with a dial gauge and bridge, and how the result selects a one, two or three-bore gasket. Valve adjustment is documented with the cold clearances, the tightening order and the two-position crankshaft procedure. The common-rail section sets out the low-pressure supply circuit with water separator and transfer pump, the two camshaft-driven high-pressure pumps, the rail with pressure sensor and pressure relief valve, and the electronically controlled injectors.

Powertrain, Swing and Travel

The power train chapters describe how the main pump, main control valve, centre passage and travel motor drive the transfer gearbox and then the propeller shafts, axles and planetary hubs. The transfer gearbox section covers both the 2HL100 and HL270 variants with their ratios, oil capacities, shift lock function, parking brake emergency release and control pressure values. The swing gearbox chapter includes the RGS 050-19D model code, the two-stage planetary reduction, the sectional and exploded views, wear limits and the complete disassembly and reassembly sequence with bearing and seal fitting notes. The travel gearbox removal and installation procedure is illustrated step by step with lifting and draining precautions.

Hydraulics and Electrical Reference

The hydraulic chapters document the main pump as a K5V80DT tandem variable-displacement piston unit, with maximum and minimum flow adjustment procedures and the port connection table. The main control valve section identifies the valve stack, the main relief valve behaviour under normal and boosted pressure, and the internal construction of the boom and arm holding valves. The circuit diagrams show exactly how pilot oil is routed for each machine function. The electrical section backs this up with the E-ECU and V-ECU pin tables, the fault code descriptions for the engine, instrument and vehicle controllers, and the wiring diagrams needed to trace a circuit from fuse to component.

Who This Manual Is For

This Volvo EW145B Service Information manual suits the workshop technician, fleet mechanic or serious owner who needs the factory assembly and adjustment data for the D6D EOE2 engine and the EW145B machine systems. Because the torque values, measuring conditions and circuit diagrams are given per function group, it supports everything from a top-end engine overhaul and valve clearance setting through to diagnosing a controller fault code, overhauling a swing gearbox or tracing a hydraulic pilot circuit. Following the published torques and clearances matters on a machine like this – an incorrectly selected cylinder head gasket or a missed torque step can cause repeat failures, and the manual removes that guesswork.
