JLG 600A, 600AJ 2013 Parts Catalog – Factory OEM Specs for Your Workbench

You’ve got a JLG 600A or 600AJ on the lift, the operator is breathing down your neck, and you need the right part number for that drive hub seal – not a guess from a third-party source. I’ve been there. That’s why this 2013 Parts Catalog sits on my bench, not some .pdf from a forum. 282 pages of factory exploded views, OEM part numbers, and diagrams that match the actual machine. No aftermarket interpretations, no “compatible with” nonsense.

Frame Section: Axle, Steering, and Drive Hardware

Section 1 covers the frame – 9 figures starting with Figure 1-1 Axle Installation. Need the steering cylinder for an 8ft wide machine without a tow package? Figure 1-2 gives you the exact part breakdown. Same for the tow-package variant (Figure 1-3) and the 7ft narrow machines (Figure 1-4). The drive hub assembly (Figure 1-6) and drive motor assembly (Figure 1-7) show every bolt, seal, and gear. If you’re rebuilding the drive valves or shields, Figure 1-8 has the layout. Optional tow package? Figure 1-9.

Turntable Section: Engines, Pumps, and Valve Blocks

Section 2 is where the real money is. Control valves, main valve block, accessory valve assemblies – Figures 2-1 through 2-3. Swing drive and turntable bearing lock installation (Figure 2-4) is critical for safety: one wrong bolt grade and you’re looking at a turntable separation. Engine installations for Deutz D2011L4, Deutz TD2.9L4, and GM engines – Figures 2-6, 2-7, 2-8. Piston pump and gear pump assemblies (Figures 2-9, 2-10) with all part numbers. Tank installations, rotary coupling, ground control box, electrical options – it’s all diagrammed. Generator options? Figures 2-17 through 2-20 cover 2500W and 7500W SkyPower generators for both Deutz and GM machines.

Boom and Platform: Cylinders, Controllers, and Rotators

Section 3 gets into the boom structure. Figure 3-1 (600A) and Figure 3-2 (600AJ) show booms and cylinder installation – note the different cylinder part numbers between models. Tower boom assembly (Figure 3-3), main boom (Figure 3-4), rotator assemblies (Figure 3-5), and boom-mounted valves/switches (Figure 3-6). Section 4 covers the platform: platform assemblies (Figure 4-1), fall arrest platform components (Figure 4-2), console assembly (Figure 4-3), and controller assemblies for lift/swing and drive/steer (Figures 4-4, 4-5). Optional platform padding and soft touch system installs are in Figures 4-6 and 4-7.

Cylinder and Hydraulic Diagrams: When a Seal Kit Isn’t Just a Seal Kit

Section 5 lists every cylinder assembly: axle lockout, level (slave), upright level, jib lift, main boom lift, tower boom lift, master, steer (both widths), and telescope cylinders – Figures 5-1 through 5-11. Each one includes the part numbers for seals, rods, and pins. Section 6 delivers the hydraulic diagrams – drive hydraulic for 2WD/2WS and 4WD/2WS, oscillating axle diagram, standard hydraulic diagram, and a hydraulic diagram list (Figures 6-1 through 6-5). If you’re chasing a hydraulic leak or rebuilding a circuit, these factory schematics save you from chasing ghosts.

OEM vs Aftermarket: Why This Manual Cuts the Guesswork

I’ve seen techs order a “universal” seal kit for a JLG cylinder and end up with the wrong bore size. This catalog is OEM – part numbers cross-referenced to the factory drawings. The Section 11 Parts Number Index runs from page numbers like 3-8, 3-21, 2-40, etc. You can look up a part number and land on the exact figure where it’s used. No aftermarket cross-reference. No “this might fit” listings. The revision log (September 1, 2013, original issue) confirms this is a first-run OEM manual, not a reprint.

Audience Fit: Who Needs This on Their Bench?

If you’re a shop owner or a lead tech handling JLG boom lifts, this catalog is your parts bible. DIY enthusiasts with a 600A or 600AJ – you need this to avoid ordering wrong parts and burning money. Beginners? Don’t touch a boom lift without the factory part diagrams. One mistake on a swing drive bearing could cost you a machine. The manual covers serial numbers from 0300177361 onward, including both US-built (prefix 03) and China-built (prefix B3) machines.

3 Reasons to Choose OEM Documentation

First, the part numbers are verified against the actual production line. Second, the exploded views show assembly order – critical for rebuilds. Third, the hydraulic and electrical diagrams in Sections 6 and 7 are factory originals, not redrawn by a third party. You want the diagram that the JLG engineer signed off on, not something a graphic artist guessed at. Check the electrical diagram list (Figure 7-1) and harness component installation (Figure 7-2).

Does this manual include torque specs for assembly?

No. This is a Parts Catalog, not a service manual. It lists part numbers and exploded views. For torque values, you need the service manual.

Will this manual cover both 600A and 600AJ models?

Yes. The catalog explicitly covers both models from serial number 0300177361 to present. Figures like 3-1 and 3-2 differentiate between the two.

Can I use this to order parts for a 2015 model 600A?

This catalog is for 2013 production. Later machines may have updated part numbers. Check the serial number range. For 2015 machines, see the JLG 600A 660AJ 2015 Service and Maintenance Manual or the JLG 600A, 600AJ 2015 Operators Manual – Factory OEM Specs for updated part information.

What is the difference between this Parts Catalog and an Operator’s Manual?

A Parts Catalog gives you exploded diagrams and part numbers for ordering. An Operator’s Manual covers daily use, safety, and basic maintenance. Both are OEM but serve different purposes. For a telehandler parts breakdown, see the JLG 8042, 10042, 10054 2012 Parts Catalog – Factory OEM Skytrak Manual.

When you’re staring at a pile of parts and need to know which pin goes where, this catalog does the talking. Automotive Industry Overview aside, real workbench knowledge comes from factory docs. Access the Factory Manual now and stop playing parts roulette.
