Read as a whole, this is not a collection of isolated specification tables – it is a full teardown and rebuild guide. Each system section opens with its own specifications and tightening torques, walks through trouble diagnosis and corrections, then takes the assembly apart in order and puts it back together with the service limits and adjustment values printed where the work happens. Exploded views, cross-sections and hydraulic and electrical circuit diagrams are used throughout so that a technician can follow the physical order of the job rather than guess at it.

Supplementary Equipment and Option Manuals Included

Beyond the sixteen service sections, this file also carries a substantial set of factory documentation for the equipment fitted around the base truck. These are not afterthoughts – they cover assemblies that are serviced on the same machines and are frequently missing from the used market:

• MANN + HUMMEL SMF-AR diesel particle filter with active regeneration – full installation manual and operating and maintenance manual covering the additive dosing system, filter system, differential pressure and temperature sensors, air flow sensor, cable harness, ECU programming from CD, indicator module menus, error list and maintenance report
• Air conditioner workshop manual (Rosti and Climasur) – bilingual diagnostic and intervention manual covering compressor, condenser, axial motor fan, dryer filter, evaporator, heating, expansion valve, centrifugal blower, thermostat, switch, relay and fuse, oil level checking, refrigerant charging and wiring diagrams
• LPG low level warning system installation instructions for 1D1 and 1D2, with swing down and swing back variants, part numbers and meter panel settings
• Crystal cabin kit assembly instructions for 1D1 / 1D2 covering front side, rear frame, doors, heater, steel roof and noise reduction kit
• Speed limiter for 1D1 / 1D2 QD32 diesel with automatic transmission – unit layout, system diagram, setting the limitation speed with the diagnosis kit, error code table and wiring diagrams
• Additional option documentation for the license plate option, GPS tracker, engine auto stop QD32, USB connector, LPG reserve tank and the integral forks positioner

Who This Manual Suits

This is written for the working technician, the fleet workshop and the owner-operator who intends to keep a 1D1 or 1D2 truck running properly rather than pay for every job. Because the manual identifies the truck by model classification number and serial number prefix, it lets you match the correct specification to the correct machine before a spanner is picked up. Gasoline, LPG and diesel variants are all covered, as are both mechanical and fingertip controlled cargo valves, so the same document serves a mixed fleet.

The diagnostic material is one of the strongest parts of the file. The automatic transmission section includes line pressure testing and stall speed testing with the correct service limits, the differential carrier section explains backlash, preload and tooth contact adjustment, and the vehicle control section lists the complete diagnosis trouble code table with detection conditions and the action each code triggers. That is the difference between replacing parts and fixing a fault.

What You Can Do With This Nissan 1D1 1D2 Forklift Service Manual

With this manual on hand you can pull and refit the engine with or without the transmission and differential carrier attached, strip and rebuild the automatic transmission including the torque converter, oil pump, clutch drum and control valve, set up the differential carrier from scratch, overhaul the drive axle and steering axle, adjust wheel bearings and kingpins, rebuild the service brake and hand brake, and work through the full hydraulic system from pump to control valve to mast and tilt cylinders.

You can also set mast roller clearances and roller pitches for 2W, 2F, 3F and 3V masts, adjust lift chain tension and carriage height, service the fuel and exhaust systems including LPG components and the QD32 injection system, and diagnose electrical faults using the wiring diagrams, fuse identification, monitor modes and trouble code tables. Every one of those jobs is supported by the correct tightening torque, service limit or adjustment value printed at the point of use.

Getting those values right matters. Forklift assemblies carry heavy loads at height and a mast roller set to the wrong clearance, a differential carrier assembled with the wrong preload or a brake shoe clearance outside its limit will show up as instability, noise or premature failure. Working from the manufacturer’s own procedures and figures is the shortest route to a repair that holds.
