Description

Doosan D20NX-D38NX Forklift Parts Book – Document SB1802E00

This is the full Doosan Parts Book SB1802E00 for the D20NX(M), D25NX(M), D30NX(M), D33NX(M), D35NX(M) and D38NX(M) series forklifts fitted with the QUANCHAI CR493 export engine rated at 36.7 kW. It covers both MECHANICAL type and POWERSHIFT type trucks across model codes FDA57 through FDA68, with serial number breakouts that let you match the exact part fitted to your machine by serial range.

Anyone who has ordered the wrong bearing, seal, or hydraulic line for a Doosan NX-series truck knows how much time that costs. This Parts Book SB1802E00 removes the guesswork – every serviceable component is listed with its Doosan part number, description, and quantity, and every group is backed by an exploded illustration that shows exactly how the assembly goes together. Whether you run a workshop, a rental fleet, or a single D30NX on a loading dock, this Doosan D20NX-D38NX forklift parts catalog gives you the exact reference Doosan dealers and parts depots use to identify components.

How the Manual Is Structured

Each group within a section opens with an illustration page showing the assembly, followed by a parts list table with columns for item number, part number, quantity, and part name. Sub-components are indented beneath the parent serviceable item so you can see immediately whether a part is sold on its own or comes as part of a larger assembly. Serial number breakouts (for example, FDA29 [38 ~ 999999], FDA31 [639 ~ 999999], FDA36 [138 ~ 999999]) appear inline wherever a component changed during production, so you order the right revision for the truck in front of you.

The engine section alone breaks the QUANCHAI CR493 down into the timing gear case, timing gear assembly, piston and connecting rod assembly, camshaft, crankshaft and flywheel, cylinder head, cylinder head cover, cylinder block, flywheel housing, fuel filter, fuel supply system, oil pipe, high pressure lines, fuel injection, oil sump, intake group, start motor, ECU, thermostat, generator, wiring harness, oil filter, injection pump, oil pump, and water pump with fan – each with its own detailed illustration and part list.

The driving module section is where most drivetrain work happens, and it is fully documented: wheel brake assemblies for 2.0-3.0T and 3.3-3.8T, the drive axle, steer cylinder, both NX and NXM transmissions, clutch assemblies, charging pump, solenoid control valve, inching valve, shift gear parts I and II, the reduction and differential assembly, and the complete steering axle group – all broken down to bearings, seals, shims, snap rings, and springs with part numbers.

What This Doosan Parts Book Enables You to Do

With this Doosan D20NX-D38NX forklift parts book open on your screen, you can identify and order the correct component for any serviceable assembly on the truck. That includes brake shoes, wheel cylinders, bearings, oil seals, O-rings, shims, snap rings, gaskets, pistons, valves, hydraulic hoses, hydraulic cylinders, mast chains, sheaves, side shifters, tilt cylinders, seats, lamps, strobes, and the entire QUANCHAI CR493 engine parts set.

Getting the part number right the first time matters because Doosan built these trucks across a wide production run with running changes. A brake assembly, a column assembly, an attachment line bracket, or a hood latch can differ by serial number. This catalog flags those differences so a replacement part actually fits. For a fleet workshop, that means fewer returns, less downtime, and faster turnaround.

The exploded illustrations are the real value here. Rather than guessing how a reduction and differential assembly stacks together, you see every gear, bearing, spacer, and shim in order. Rather than wondering whether a side shifter cylinder has a seal kit available, the carriage section lists the seal kit by part number alongside the individual rings and wipers.

Who This Doosan NX-Series Parts Catalog Is For

This manual is written for forklift technicians, fleet maintenance managers, parts counter staff, Doosan dealers, independent repair shops, and anyone rebuilding or servicing a D20NX through D38NX truck. It is equally useful whether you are ordering a single hydraulic hose or rebuilding the entire drivetrain. The part number index at the back of the book lets you work in reverse: find a part number on a shelf, look it up, and see which assembly and which models it belongs to.
