Description

Hyundai 50D 60D 70D 80D Forklift Trucks Shop Manual

This is the complete Hyundai shop manual prepared for the 50D-7E, 60D-7E, 70D-7E and 80D-7E diesel forklift trucks. It is the same reference a Hyundai service workshop uses for removal, installation, disassembly, assembly, adjustment, troubleshooting and specification work across every major system on the machine. Because the manual groups all four models in the 7E D-series on the same platform, it is written to be worked from directly at the truck rather than just read as background material.

Section 1 – General

Safety hints, conversion tables for millimetres to inches, kilograms to pounds, litres to US and UK gallons, temperature, kgf·m to lbf·ft and kgf/cm² to lbf/in², plus general specifications, a tightening torque table for major components, a coarse and fine thread bolt torque chart, flare and ORFS pipe and hose torque tables, recommended lubricants indexed by ambient temperature, and the periodic replacement schedule for consumable parts such as brake hoses, master cylinder caps, power steering hoses, lift chain and load-handling hoses.

Section 2 – Removal and Installation of Unit

Step-by-step removal and installation of the complete assemblies – mast (including shaft type and hook-on type forks, backrest and carriage), lift cylinder, inner mast, tilt cylinder pin and mast support pin, the full power train assembly, drive axle, steering axle, propeller shaft, torque converter and torque converter housing, engine assembly, and the counterweight. Includes tightening torque values for engine, drive axle, transmission, propeller shaft and torque converter housing mounting bolts, plus radiator and air cleaner hose insertion depths.

Section 3 – Power Train System

The largest chapter. Covers the ZF 3 WG-94 EC full auto power shift transmission and F&S 300 3-element torque converter in detail – torque converter function and stall ratio, transmission layout, gear train and clutch operation (KV, KR, KC, KD, KE), proportional valve hydraulic circuit, main pressure and converter safety valves, gear selector operation, TCU error display codes, electronic inching, oil level checks, oil change and filter intervals, measuring points for pressure and temperature, full transmission disassembly and reassembly of every clutch, the output shaft, oil pressure pump, central PTO shaft, converter and proportional valves with disk clearance specifications and shim calculations. Also the differential carrier assembly and drive axle structure, torque values and the wet multi-disk brake assembly.

Section 4 – Brake System

Full power hydraulic brake system – hydraulic circuit and component location, brake valve structure and partial/full braking operation, cut-off valve, brake accumulators with priming pressure and testing procedure, pressure switches, inching pedal and linkage adjustment with inching sensor initialization, disk brake operation, air bleeding, pedal adjustment, troubleshooting of brake drag, overheating, noise, spongy feel and unequal braking, plus brake valve disassembly and reassembly with torque values.

Section 5 – Steering System

Full hydraulic power steering circuit, steering unit structure and operation (control valve plus gerotor metering), priority valve with LS, CF and EF ports, steering cylinder specifications and seal replacement, steering axle structure, knuckle, king pin, hub and taper roller bearing, toe-in, camber, caster and king pin angle values, steering angle 75.87°/51.43°, hub nut torque, and step-by-step disassembly and assembly of the steering unit, priority valve and steering cylinder.

Section 6 – Hydraulic System

Fixed displacement gear pump structure and rebuild, sectional main control valve (5-spool layout for lift, tilt and auxiliary), main relief valve set at 181 bar with secondary at 147 bar for 3 and 4 spool versions, load check poppet operation, tilt lock spool, remote control valve (RCV) operation, lift cylinder and tilt cylinder structure with seal kits, hydraulic drift limits (100 mm down and 5° forward after 10 minutes), hydraulic oil recommendations and troubleshooting for slow lift, drift, abnormal noise and overheating.

Section 7 – Electrical System

Full component location, complete electrical circuit including power circuit, starting circuit, charging circuit and preheating circuit with glow plug circuit, fuse box A and B layout, ECU and TCU pinouts, connector destination tables with connector part numbers, transmission error code diagnosis, sensor resistance and cable measurement procedures, component specifications and electrical troubleshooting.

Section 8 – Mast

Two-stage V mast and three-stage TF mast structure with exploded views, carriage, backrest, hook-on and shaft type forks, mast load roller and carriage load roller clearance adjustment (reference values 43.1 mm and 56.9 mm), carriage assembly removal, side roller adjustment, chain sheave replacement, load chain inspection for wear, rust, cracked plates, tight joints, turned pins and side wear, chain wear scale limits (replace at 2% elongation) and load chain lubrication at 200-hour intervals.

What This Hyundai Forklift Shop Manual Lets You Do

With this manual on hand you can carry out the same jobs a Hyundai service technician would: remove and reinstall the mast, engine, transmission and drive axle; rebuild the ZF 3 WG-94 EC transmission and its five clutches with correct disk clearances; service the wet multi-disk brakes and bleed the full power hydraulic brake circuit; rebuild the hydraulic gear pump and sectional main control valve; replace the steering unit seals and set the axle camber and king pin angles; chase electrical faults through the start, charge, glow and TCU circuits; and adjust mast and carriage load rollers and chain tension so the upright sequences correctly.

Correct procedures and the right specifications matter on a forklift because a badly set chain, a mis-shimmed pinion or an incorrectly bled brake circuit can lead to a load drop, a runaway on a slope or premature transmission failure. Every value you need is printed here – torque figures in kgf·m and lbf·ft, relief pressures, oil capacities, seal sizes, shim thicknesses and clearance limits.
