Description

Daewoo DV15 Series Diesel Engine Operation & Maintenance Manual

This is the full operation and maintenance manual prepared by Daewoo Heavy Industries Ltd. for the DV15, DV15T and DV15TIS diesel engines. These are 8-cylinder, 4-stroke, V-shape, direct-injection engines built for overland transport and industrial duty, and the DV15TIS version is the environment-friendly model that satisfies the EURO2 emission regulation. Every procedure, value and illustration in this Daewoo DV15 series manual is drawn straight from the factory publication, so you are working from the same reference the service line uses.

Specifications, Preventive Maintenance and Troubleshooting

The opening section lays out the full engine specification table across DV15, DV15T, DV15TI and DV15TIS — bore and stroke, total displacement, compression ratio, maximum power and torque ratings, injection timing, firing order and valve timing. Performance curves for each model are plotted with the test conditions noted. The preventive maintenance chapter then walks through cooling water and antifreeze ratios, fan belt tension, engine oil change intervals, oil and fuel filter service, air cleaner care, valve clearance and compression pressure testing. The engine troubleshooting chapter is written as fault trees covering engine won’t start, overheating, lack of power, low oil pressure, excessive fuel consumption, excessive oil consumption, engine knocks and battery discharge, with a detailed complaint/cause/correction table for each.

Engine Overhaul, Inspection and Reassembly

This is the largest part of the DV15 workshop content. It takes the engine down step by step — oil level gauge, engine oil, cooling water, cooling fan, V-belt, alternator, vibration damper, oil filter, water pump, starter, fuel filter, injection pipe, oil cooler, turbocharger, exhaust and intake manifolds, air compressor, injection pump, cylinder head cover, nozzle holder, rocker arm, cylinder head, oil pan, oil pump, piston, front oil seal holder, flywheel, flywheel housing, crankshaft, camshaft and tappet, oil spray nozzle and cylinder liner. The inspection and correction chapter then gives you the measuring procedures and service limits for the cylinder block, cylinder liner bore, cylinder head, valves and valve guides, valve seats, valve springs, rocker arm shaft assembly, tappets and push rods, camshaft axial play and run-out, crankshaft journals and pins, undersize bearing options, piston and piston rings, piston pin, connecting rod bend and twist, thermostat, and injection nozzle testing. Reassembly follows the same order with tightening sequences and torque stages for the main bearing cap bolts, connecting rod bolts, flywheel bolts, cylinder head bolts and rocker arm assembly, plus valve clearance adjustment charts and the engine break-in procedure.

Turbocharger

Dedicated to the DV15T, DV15TI and DV15TIS turbocharged engines. It documents the turbocharger specifications and construction, how the turbine and compressor work together, the thrust and floating journal bearing design, and sealing arrangement. Handling precautions cover cold-start oil supply, idling before shutdown, and why you never rev a turbo engine on start-up or switch it off at high rpm. Walk-around check and maintenance guidance follows for the air intake, exhaust, fuel and lubricating systems, then periodical servicing including rotor rotation checks, axial and radial clearance measurement with wear limits, and cleaning tips. A diagnostics and troubleshooting table lists excessive smoke, white smoke, low output, unusual sound and vibration against their causes and corrections.

Fuel Injection Pump

Calibration and test data for each DV15 variant’s injection pump, given both by Daewoo part number and BOSCH reference. Separate data sets are provided for DV15 (RQ), DV15T (RQ), DV15T (RQV), DV15TI (RQ) and DV15TIS (RQ). For each pump you get the pump body, governor, feed pump, timer, plunger and delivery valve data, pre-stroke, rotating direction, injection order and injection timing, followed by the calibration table with rack positions, pump speeds, injection volumes and variation rates, LDA adjust data, and the governor performance curve plotted against pump speed. Adjusting conditions such as nozzle holder assembly, nozzle type, opening pressure, injection pipe dimensions, fuel inlet pressure and temperature, and oil specification are also tabulated.

Supplement

The closing supplement collects the tightening torque ratings by group and thread size, the full maintenance specification tables for the block, piston assembly, connecting rod and crankshaft, and the special tool list with part numbers for the compression test connection, injector holder spanners, cylinder liner mandrel and extractor, dial gauge holders, valve tools, injection line spanners and air compressor service tools.

Why This Daewoo DV15 Diesel Engine Manual Belongs in Your Workshop

IMAGES PREVIEW

Whether you are running a fleet of trucks, a piece of industrial plant or a single Daewoo-powered machine, the difference between a repair that lasts and one that comes back is having the correct procedure and the correct number in front of you. This manual lets you set valve clearance, compression-test each cylinder, time the injection pump, adjust nozzle opening pressure, measure liner and crankshaft wear against the factory limits, and rebuild the top and bottom end to the right torque stages. The fault trees alone will save you diagnostic hours when an engine refuses to start, runs hot or loses power. Everything is delivered as an instant PDF download — no shipping, no waiting, viewable on a laptop, tablet or phone in the workshop, and printable for the pages you want on the bench.
