Description

Doosan B20SE-5 B25SE-5 Electric Forklift Parts Book – What’s Inside

The SB1248E04 parts book is Doosan’s complete illustrated parts catalog for the B20SE-5 and B25SE-5 electric counterbalance forklifts. Every serviceable component in the chassis, drive module, electric power system, operating module, mast, fork, and carriage assemblies is broken down into exploded-view illustrations with item numbers, Doosan part numbers, required quantities, and exact part names. This is the reference you reach for when a customer calls about a steering cylinder seal kit, a brake master cylinder, a hydraulic hose on a 4-way mast, or a replacement seat switch – and you need the correct part number the first time, not the third.

Chapters Covered

The parts book is organized into three top-level groups – CHASSIS, FRONT END, and MISCELLANEOUS – each with detailed sub-assemblies.

• CHASSIS > Chassis
• CHASSIS > Driving Module
• CHASSIS > Electric Power
• CHASSIS > Operating Module
• FRONT END > Mast
• FRONT END > Fork
• FRONT END > Carriage
• MISCELLANEOUS > Location Chart

CHASSIS > Chassis

The largest chapter in the book, covering the frame and every major assembly bolted to it. You get exploded views and part breakdowns for the steering axle group (beam, knuckle assemblies, king pins, tapered roller bearings, seals), service brake and parking brake assemblies with the master cylinder internals, the drive controller group, hydraulic gear pump and pump-motor assemblies, the Curtis drive motor, floor plates, outer panels, the overhead guard, the hydraulic tank with strainer and breather, brake lines, power steering lines, and the mount groups for the steer axle and tilt cylinders. Every tilt cylinder variant – 3°/5°, 6°/10°, 6°/3°, 6°/5°, 6°/8°, 3°/10°, 3°/8° – is broken down to rod, tube, piston, seal kit and check valve level. The counterweight group is covered separately for B20SE-5 and B25SE-5, so you order the right one the first time.

CHASSIS > Driving Module

The transaxle and wheel-end chapter. Exploded views cover the transaxle arrangement, transfer assembly, axle housing, differential gear set, bearings, shims, oil seals, drive shafts (LH and RH), brake assembly internals with friction discs and pistons, and the wheel hub groups. Tire and wheel arrangements are also catalogued here for pneumatic, solid softer narrow, and non-marking narrow configurations, with tire, tube, rim, side ring, locking ring, and wheel nut part numbers.

CHASSIS > Electric Power

Battery, charger, and high-current connection hardware. The battery section catalogs the major pack options – 48V/715AH, 737AH, 740AH, 800AH, 600AH dry, 640AH Hoppecke, and 660AH dry – down to cell assembly, connector, welding wire, sleeve, strap, and battery cap level. The charger section documents each charger variant by voltage, phase, frequency, and AH rating, with transformer, PCB, magnetic switch, fuse, shunt, diode module, output cable, and input cable part numbers. Battery connector groups – SB350 gray, SBE320 blue, emergency SB350, and cabin emergency – are also listed with terminal, cap, and cable assembly details.

CHASSIS > Operating Module

Everything the operator sees and touches. Alarm and back-up buzzer groups, cabin modular A/B/C frames and covers, full-cabin changeover arrangements, doors (rear, fixed RH, open RH/LH), wiper assemblies, the front cockpit unit with Curtis instrument group and steering column, control valve arrangements (2-, 3-, and 4-section with matching lever and bracket assemblies), individual section valve groups for lift, tilt, AUX1, and AUX2, priority valve, seat groups (static, suspension, NACD, cloth, AMA, Crown option), seat belt interlock and retractable belt options, heater group, power socket, lamp groups (head, combination, rear, cabin, strobe), mirror groups (large, panoramic, round), overhead guards in 2100/2133/2220 mm widths, grab bars, and the full range of cabin electrical harnesses and displays.

FRONT END > Mast

This is the most granular chapter in the book. Doosan catalogues every mast from 2580 mm standard duplex through FFT, FFL, and quad configurations up to 8200 mm, plus the 3-way and 4-way merchandising variants. Each mast arrangement carries its own mast group, primary lift cylinder, secondary cylinders (LH and RH), lift-and-tilt mounting group, relay/sheave group, and chain specification. Primary and secondary cylinders are broken down to rod, tube, piston, check valve, seal kit, wiper, and O-ring level. Tilt cylinder groups are catalogued by angle configuration, and merchandising packages (3-way, 4-way, integral side shifter, fork positioner) are itemized with sheave groups, hose assemblies, couplings, brackets, and bulk hose sold by the centimeter.

FRONT END > Fork

Hook-on fork options for 2.0 and 2.5 ton capacity, with fork caps and a range of fork part numbers covering different lengths and attachment configurations. Fork positioner groups are also catalogued here.

FRONT END > Carriage

Standard, FFL, and FFT carriage arrangements, load backrests (multiple styles including Crown option), carriage mounting group with bearings, shims, and retainer rollers, fork mover attachments, side shifter and fork mover combinations, quick couplers (3-way and 4-way), integral side shifter line group, and the side shifter cylinder assembly broken down to tube, rod, piston, seal kit, and head.

MISCELLANEOUS > Location Chart

How This Parts Book Helps You

A 48-volt electric forklift is only as productive as its weakest seal, hose, or switch. When a B20SE-5 or B25SE-5 comes into the shop with a weeping tilt cylinder, a dead back-up alarm, a cracked strobe lens, a sloppy steering knuckle, or a battery connector that has arced one too many times, you do not want to guess at the part number. This parts book gives you the exact Doosan part number, the quantity required, and the assembly context in one place. The exploded views let you confirm you are looking at the right side – LH vs. RH, inner vs. stationary upright – before the order goes in. That is the difference between a one-trip repair and a truck sitting on blocks waiting for a return.

Because the book is serial-number-specific (FBA14 and FBA15), you can match the part to the machine in front of you rather than to a generic catalog photo. The mast chapter alone spans thousands of millimeters of lift height, and the merchandising packages change the hydraulic routing completely – having the right section in front of you prevents ordering a hose assembly that fits a 4-way FFT but not a 3-way STD.
