Engine Parts — Fig. 011 to 035

The engine section opens with the cylinder block, timing gear case, bearing case, flywheel housing and crankshaft assembly. It then moves through piston assembly, cylinder head, engine timing components, oil pump, oil pan and oil cooler. Cooling system coverage includes the water pump and related components. Air and fuel systems are covered through the intake/exhaust manifold, turbocharger, nozzle and holder, injection pipe, injection pump, fuel strainer and fuel filters. The section closes with the generator, starter, air compressor and engine mounting. Each exploded illustration is keyed to a parts table listing key number, part number, description, quantity and service code.

Body Parts — Fig. 1100 to 1410

The body section covers the main frame and engine mounting, then moves through the air cleaner, radiator and swing device. Piping coverage includes lubrication, pilot, main and oil cooling circuits. Tank and pump components include the oil tank, fuel tank and filler pump. Engine control is covered through the control cable, auto idle system and control lever. The section also includes heater piping, cooler, electric parts, control stand, cabin, cabin parts, support brackets and covers. These diagrams are particularly useful when tracing hydraulic lines, identifying mounting hardware or replacing cab components.

Track Parts — Fig. 2100 to 2190

The track section covers the complete undercarriage: track assembly, propelling piping, idler, track spring, upper roller, lower roller and track shoe assembly. These illustrations help you identify undercarriage components by position and part number, which is essential when ordering wear parts or rebuilding a track frame.

Front Parts — Fig. 3100 to 3130

The front section covers the front attachment, bucket (1.3 m³), front piping and front lubrication piping. These diagrams are useful for identifying bucket teeth, linkage pins, hydraulic cylinders and lubrication points on the front end of the machine.

Other Parts — Fig. 4100 to 4120

The Other Parts section includes tools, spare parts and name plates for both domestic and export models. This is where you will find the smaller items that are easy to overlook but necessary for a complete repair.

Option Parts — Fig. 5100 to 5270

Option parts coverage includes the tropical cover, air condenser fan, breaker piping, idle pulley (without air conditioning), short arm assembly (2.5 m), auto idle piping, arm (4.1 m), bucket options in 0.8, 1.6, 1.7, 1.8, 1.9 and 2.0 m³, bucket without tooth, defroster assembly, cabin fresh air, cabin window guard, travel alarm, seat assembly and track link assemblies in 700G, 800G and 850G. If your machine is fitted with optional equipment, this section is essential for identifying the correct part numbers.

Hydraulic Components — Fig. 6100 to 6440

The hydraulic section is the most technically detailed part of the catalog. It covers the main pump (K3V180DT), main pump block, regulators, gear pump, control valves (LH and RH), AE valves, swing motor, reduction device, travel motors, travel reduction device, remote control valves, shuttle valve blocks, solenoid valves, boom cylinder, arm cylinder, bucket cylinder, auto idle cylinder and center joint. Each assembly is exploded with key numbers linked to the parts listing, making this section invaluable for hydraulic troubleshooting and repair.

What This Parts Catalog Enables You to Do

This DH320 parts manual is built for the workshop, the parts counter and the field service truck. With it you can:

• Identify the exact part number for any component by matching the key number on the exploded illustration to the listing.
• Verify quantities for assemblies and sub-components, including parts marked as components of an assembly.
• Cross-reference replaceable part numbers and interchangeability codes (I, P, T, Y) to understand which alternative parts will fit.
• Order the right component the first time, avoiding returns, downtime and incorrect fitment.
• Understand service codes that flag parts requiring machining before installation, grade-controlled parts, and optional or oversized/undersized components.

Why the Correct Part Number Matters

On a machine as complex as the Daewoo DH320, a single digit out of place in a part number can mean the difference between a component that bolts straight on and one that does not fit. This DH320 parts catalog uses the manufacturer’s own exploded-view format: each illustration is keyed to a table showing key number, part number, description, quantity and service code. The manual also identifies assembly components, interchangeable parts and replaceable part numbers, so you are not guessing at what will work. Because this is the Daewoo DH320 parts list covering serial number 0001 and up, it applies to the full production run of the machine.
