Description

JLG 600A / 600AJ Illustrated Parts Manual – Document 3120719 Rev AM

This is the full JLG 600A 600AJ Illustrated Parts Manual, published under document number 3120719 at Revision AM. It is the parts identification reference for the 600A and 600AJ boom lift series, and it spans every major assembly on the machine – from the front axle and steering installations through the turntable, boom sections, platform, hydraulic cylinders, electrical harnesses and decal sets. Each figure pairs an exploded illustration with a numbered parts table listing item number, part number, quantity and description, so any component on the machine can be traced to its correct part number before ordering.

What this gives a technician is a single organized reference for identifying every serviceable component on the 600A and 600AJ. The manual is structured so that assemblies are broken down into their constituent parts, each tied to a figure number and an item callout on the illustration. Because the same assembly can change across production – the manual documents serial number breakpoints throughout – the parts tables identify which variant applies, so the correct part is selected for the machine on the shop floor rather than a superseded or incompatible one. Service replacement kits, seal kits, and complete assembly part numbers are listed alongside the individual components where they exist, which matters when a full rebuild is more practical than piece-by-piece sourcing.

Serial Number Coverage

Part listings throughout the manual are keyed to machine serial number ranges, from early production units through the 0300069000 series. The manual documents multiple break points across the frame, boom, cylinder, engine and control system sections, and where applicable an assembly is listed with “prior to” or “through” serial number notes so the correct revision is identified. Machines built from S/N 0300064249 onward incorporate the ADE (Advanced Design Electronics) System, and the manual contains distinct sections for those machines, including the ADE ground control box, platform console assembly and controller assemblies.

Engine and Powertrain Variants Documented

• Continental TMD-27 diesel engine installation
• Deutz F4M1011F diesel engine installations, with and without noise reduction
• Ford LRG-423 engine installations
• Ford LRG-425 engine installations with carburetor
• Ford LRG-425 engine installations with EFI
• Isuzu 4JB1 engine installation
• Dual fuel installations for Ford engine machines with carburetor and with EFI

Each engine section covers the engine mounting hardware, radiator and cooling components, air cleaner, exhaust and muffler, oil drain, battery and cable kits, throttle actuator and governor components, and the engine-side accessories. Generator installations for 110V and 220V systems are broken down by engine variant and serial range, including control box, receptacle and breaker components.

Hydraulic, Electrical and Cylinder Content

The hydraulic diagrams section covers the drive circuits for 2WD/2WS and 4WD/2WS, the oscillating axle circuit and the standard machine circuit, with every fitting, hose and valve called out by part number. The electrical section includes wiring schematics for diesel, gas, EFI, UL and LP-only machines, plus the ADE system schematics, and the harness components installation figures break down the platform box harness, boom cables, ground control box harness, engine harness and valve harness by connector, socket, pin and seal. Section 5 covers every hydraulic cylinder on the machine – axle lockout, platform level, slave, upright level, articulating jib, main lift, tower lift, master, steer, main telescope and tower telescope – with barrel, rod, head, piston, bushing, cartridge valve and seal kit part numbers, including original equipment and service replacement versions.

Why This Parts Manual Matters

Ordering the wrong part on a boom lift is expensive in both money and downtime. The JLG 600A 600AJ Illustrated Parts Manual 3120719 gives you the figure numbers, item callouts and part numbers that let you confirm exactly which component belongs to your machine before the order goes out. Every figure is tied to the machine’s serial number breaks and engine configuration, so a part for an early 600A with a Continental engine is not confused with the equivalent position on a later 600AJ with a Deutz or Ford EFI engine. Seal kit and repair kit part numbers are included where the manufacturer packages components together, and the recommended service parts stock section tells you which items are worth keeping on the shelf for field repairs.

Instant PDF Delivery

The manual is delivered as an instant PDF download after checkout – no shipping, no waiting on a physical book. Once downloaded, the file is yours to keep. It can be opened on a laptop, tablet or phone in the shop, printed as individual pages for the job at hand, or printed in full for the service library. Search and navigation work the same way as any other PDF document on your device, so you can jump straight to the figure or part number you need.
