What This JLG Parts Manual Enables You To Do

With this 600A/600AJ illustrated parts manual you can identify the correct part number for any component on the machine before you place an order – axles, drive hubs, drive motors, swing hubs and motors, main and accessory valves, piston and gear pumps, hydraulic cylinders of every type, rotary couplings, ground control boxes, platform consoles, controllers, decals and special options. Every part number in the manual is indexed so you can move from the numeric index straight to the correct page, and exploded illustrations show exactly where each item fits and which quantity is required. Whether you are sourcing a single seal kit for a cylinder, replacing a drive motor with its correct service-replacement variant, or ordering every gasket and fitting needed for an engine installation, the exact part numbers are here.

Why This Manual Matters

Ordering the wrong part on a boom lift wastes time and money. JLG uses serial-number-dependent changes across the 600A and 600AJ lifecycle, and this manual flags every change point – so instead of guessing which valve assembly, hub, motor or cylinder variant matches the machine in front of you, you can look it up by serial number range and be certain. Part number supersessions are documented, NLA and NSS items are called out, and every installation is broken into a figure with the exact item numbers, part numbers, quantities and descriptions – which is what professional parts sourcing on these machines requires.
