How This Manual Supports Your Work

This Mitsubishi Unicarriers 1F2 Series QD32 Engine Chassis Parts Manual is designed to eliminate the uncertainty that comes with ordering parts for forklift trucks. Each exploded-view illustration is accompanied by a parts list that provides the reference number, part number, interchangeability code, part name and description, model applicability, quantities, and applicable serial number ranges. This means you can confirm that the part you are ordering is correct for your specific truck configuration before it ships.

The manual covers both ATM (automatic transmission) and MTM (manual transmission) variants, dry and wet clutch configurations, and a wide range of optional equipment including cabins, heaters, and different hydraulic control valve arrangements. Whether your truck has a 2-spool, 3-spool, 4-spool, or 5-spool hydraulic control valve, whether it uses fingertip control or lever control, and whether it is fitted with a standard muffler, an anti-fire spark muffler, an overhead muffler, or a DPF exhaust system, the relevant parts information is included.

Serial number ranges are clearly indicated in the applicable range columns, so you can verify that a part applies to your truck based on its serial number. This is particularly important for components that changed during the production run, such as seats, wiring harnesses, tilt cylinders, hydraulic control valves, final drive assemblies, and lighting configurations. The manual also includes interchangeability codes that tell you whether a new part can be substituted for an old one, whether they are mutually interchangeable, or whether they are not interchangeable at all — information that prevents costly ordering errors.

Systems and Components Covered in Detail

Engine and mounting: The engine assembly section covers the QD32 engine in its various configurations, along with the engine mounting brackets, insulators, and fasteners that secure it to the chassis. Note that the engine assembly itself cannot be supplied for repair — the manual directs you to order a bare or short engine instead — but all the external engine components and mounting hardware are fully listed.

Hydraulic system: This is one of the most comprehensive sections. It covers the hydraulic oil pump connector, hydraulic oil tank fitting, hydraulic oil pump assembly, and then a wide range of hydraulic control valve configurations. Separate sections address the control valve fitting for standard valves and for fingertip control valves, followed by the control valves themselves in 2-spool, 3-spool, 4-spool, and 5-spool versions. Both the pre-201208 and post-201208 production ranges are included, reflecting a significant change in valve design during that period. Control lever assemblies are covered for twin lever and single lever types, with separate lever and lever cover sections. The hydraulic oil piping sections are comprehensive, covering the lines from tank to pump, pump to control valve, control valve to lift cylinder and accumulator, control valve to tilt cylinder, lift cylinder and control valve to tank, power steering, and control valve to attachment piping for 3-valve, 4-valve, and 5-valve systems. Special attachment specifications for inner drain and outer drain are also included.

Air intake and exhaust: Multiple air cleaner configurations are documented, including the standard air cleaner, Donaldson air cleaner with overhead mounting, Donaldson air cleaner with counterweight installation, and Donaldson air cleaner with pre-cleaner. The exhaust section covers standard exhaust tube and muffler, anti-fire spark muffler, overhead muffler configurations, and DPF (Diesel Particulate Filter) exhaust systems in their various positions.

Cooling system: The radiator, shroud, and fitting section covers the radiator assembly, cap, drain cock, hoses, insulator mountings, and the radiator shroud. The cooling unit and compressor sections cover the air conditioning components where fitted. The torque converter oil cooler and piping section covers the ATM cooling circuit.

Electrical system: The wiring sections cover engine room and instrument wiring, body wiring (with separate pre-200803 and post-200803 versions), and seat belt interlock wiring. The battery and mounting section covers the battery, cables, and hold-down hardware. The instrument meter and gauge section covers the combination meter and printed circuit. The switch section is extensive, covering operation switches, turn signal switches, FNR switches, horn switches, ignition switches, speed select switches, back buzzer switches, and forward/reverse switches. Electrical unit sections cover horns, relays, and relay boxes. Lighting sections cover headlights, front combination lights, rear combination lights (with and without Syaken parts installation), licence plate lights, and auxiliary lights including patrol lamps.

Control system: The accelerator linkage section covers both the standard version and the version with 2-speed select switch. The engine control module section is particularly detailed, covering the vehicle control module across numerous configuration and date variants from 2008 through 2013. The parking brake control, brake and clutch pedals (ATM and MTM), steering gear, steering wheel, and steering column sections complete this chapter.

Power train: The clutch section covers the clutch cover, disc, and release parts for manual transmission models, including both dry and wet clutch variants. The transmission sections cover the ATM transmission assembly, torque converter case and housing, oil pump parts, governor and gear parts, clutch and brake band, and control valve. For MTM models, the transmission assembly, transmission case and cover, transmission gear, and shift lever and fork are covered. The propeller shaft, final drive assembly, drive axle, steering axle, and road wheel and tire sections cover the driveline and running gear. Both single tyre and double tyre configurations are documented. The drive axle brake section covers the brake assembly, back plates, shoes, wheel cylinders, adjusters, and parking brake cables. The steering linkage section covers the tie rod assemblies, power steering cylinder, and related components.

Cabins and options: The option chapter covers canvas cabins, front window cabins, steel cabins, and steel cabins with folding doors. The heater unit section covers the heater assembly, blower motor, heater core, water hoses, and control components.

Who This Manual Is For

This Mitsubishi Unicarriers 1F2 Series QD32 Engine Chassis Parts Manual is intended for forklift technicians, maintenance supervisors, parts department staff, and fleet managers who need to identify and order genuine components for these trucks. It is also valuable for independent repair shops that service Mitsubishi Unicarriers forklifts and need accurate parts information to complete repairs efficiently.

Because this is a parts manual rather than a service manual, it does not contain repair procedures, torque specifications, or diagnostic steps. It tells you what the parts are, what they look like, what they are called, and which models and serial number ranges they apply to. For repair and diagnostic procedures, you would need the corresponding service manual.

The exploded-view illustrations are clear and detailed, showing how components fit together and their relationship to adjacent parts. This makes the manual useful not only for ordering parts but also for understanding assembly structure when disassembling or reassembling components.

Why This Manual Matters

Ordering the wrong part costs time and money. A forklift that is out of service because the wrong seal, valve, or sensor was ordered is a forklift that is not moving product. The Mitsubishi Unicarriers 1F2 Series QD32 Engine Chassis Parts Manual removes that risk by providing the exact part numbers and applicability information you need to get it right the first time.

The serial number range information is particularly valuable. Mitsubishi Unicarriers made running changes throughout the production of these trucks, and a part that fits an early serial number may not fit a later one. The applicable range columns in this manual tell you exactly where each part applies, so you can match the part to your specific truck.

The interchangeability codes are equally important. They tell you whether a new part can replace an old one, whether an old part can replace a new one, or whether they are completely different. This information is essential when a part has been superseded and you need to know if the replacement will work in your application.
