Chassis Component

The chassis section opens with the steer axle group, covering the steering axle body, knuckles, king pins, bearings, seals, hub and wheel mounting hardware. It continues through the frame group for both 2.0/2.5-ton and 3.0-ton models, the top panel and hood assemblies with gas springs, radiator cover, weatherstrip and latch components. The air cleaner group, muffler group with exhaust tube and clamps, torque converter cooler lines, radiator group with lower hose and cushion mounts, hydraulic reservoir, fuel lines with tank gasket and filter, battery group with tray and cables, wiring group with main harness and fuse box, instrument group with gauges and warning lamps, powertrain mounting group with engine mounts and adapters, accelerator control with pedal assembly and cable, steering control group with steering unit and column, brake and inching control group, parking brake group, floor plate group, hydraulic tank cover with strainer, hydraulic lines group with hoses and fittings, pump mounting group and gear pump assembly, and the F/R control valve group are all documented with exploded views and part lists.

Capacity Module

The capacity module covers the overhead guard group with legs and mounting hardware, mirror group, counterweight group for 2.0-ton, 2.5-ton and 3.0-ton models, and the complete range of tire and wheel groups. Pneumatic, solid and dual tire arrangements are shown for both the 2.0/2.5-ton and 3.0-ton trucks, including rims, side rings, locking rings, tubes, valves and separation bolts. Fender groups for dual tire applications and the lubricant location charts complete this section.

Engine_4TNE94L 34KW

The engine chapter details the Yanmar 4TNE94L 34KW diesel engine in its major sub-assemblies: engine arrangement, fan drive group with cooling fan and V-belt, alternator mounting group with pulley and brackets, cylinder block group with main bearings and thrust washers, gear housing group with oil pump and timing gears, flywheel housing and oil pump group, cylinder head and bonnet group with valves, springs, rocker arms and nozzle, suction and exhaust manifold group, camshaft and driving gear group, crankshaft and piston group with connecting rods and piston rings, lubrication oil system group with dipstick, oil filter and oil pressure switch, cooling water system group with water pump, thermostat and hoses, fuel injection pump group, fuel injection valve group with injection pipes, fuel filter group with water separator, starting motor group with armature, pinion, clutch and magnetic switch, and the complete gasket set group.

Power Train

The power train chapter covers the transmission assembly in both GZ and SXJD variants. For the GZ transmission, the hydraulic clutch assembly, reduction and differential assembly, solenoid control valve group, inching valve assembly and charging pump assembly are each illustrated and listed. The SXJD transmission is similarly covered with its hydraulic clutch, charging pump, control valve, inching valve and reduction/differential assembly. Drive axle groups for 2.0/2.5-ton and 3.0-ton models are shown complete with wheel brake assemblies (LH and RH), brake drums, hubs, bearings, seals and axle shafts. The 3.0-ton drive axle with Code L is also documented.

Option For Complete Truck

The options chapter is extensive, covering anti-spark muffler, pre-cleaner, a wide range of seat groups (static, suspension, vinyl, cloth, with and without armrests and hip restraints), seat belts with and without warning indicator, lamp groups, rear lamp groups, strobe groups in red and amber, horn, control valve arrangements from 2-section 2-lever through 4-section 4-lever including ISO3691 configurations, tool group, fan assemblies for full cabin and overhead guard, fire extinguisher, modular cabin groups A, B and C, full cabin group and assembly, doors for RH and LH, heater group, speedometer option, autoshift controller, LED lamp groups for various cabin configurations, EU changeover arrangements, fuel cap with key, engine shut-down systems, OSS group, water injection for modular cabins, and the pre-cleaner and autoshift controller options.

The mast implements chapter documents the mast groups for BSC (standard), FFL (full free lift) and FFT (full free triple) configurations, along with the inner and outer mast assemblies for each lift height. Mounting groups for lift and tilt are shown for STD, FFL and FFT applications. Relay groups, lift relay groups for FFL and FFT, attachment lines for primary and secondary circuits in 3-way and 4-way arrangements, side shifter groups for 2.0/2.5-ton and 3.0-ton trucks with their cylinder assemblies, carriage arrangements and assemblies, backrest assemblies and fork groups complete this section.

Maintenance Parts Reference

A dedicated maintenance parts table lists the common service items with their part numbers: fuel filter, engine oil filter, transmission filter, hydraulic strainers, 90AH battery assembly, turn signal bulb, stop and tail bulb, backup bulb, halogen bulbs, 15A, 30A and 10A fuses, and touch-up paint in Doosan black and lift truck dark gray.
