JLG 3508PS, 3509PS, 3512PS, 3513PS, 4008PS 2014 Parts Catalog

You got a 3508PS on the lift with a cracked boom section and no clue which bracket part number to order. The aftermarket CD you bought skips half the frame components and lists a seal that doesn’t fit a 2014 build. That’s money out of your pocket and a customer waiting on a rental. This is the factory-issued JLG 3508PS, 3509PS, 3512PS, 3513PS, 4008PS 2014 Parts Catalog – an original PDF, not a scan of a scan. 518 pages of JLG’s own part numbers, exploded views, and revision history. I’ve torqued more head bolts than most of you have had hot dinners, and I can tell you right now: guessing parts on a lift is how you burn a weekend and still end up with the wrong hydraulic valve. Get the right document the first time.

12 Sections of Verified Part Numbers

This catalog breaks down the whole machine into 12 sections. Section 1 covers frame and attaching parts – right side shrouding, left side, axle/fender install, outrigger sets, draw bar coupling, site hitch, trailer hitch (prior to SN 116005199), auto hitch, pin hitch, and hydraulic hitch. Each figure gives you the exact part number JLG stamped on that piece. Section 2 is the boom assembly. Section 3 covers attachments. Section 4 gets into the engine and attaching parts – if you’re chasing a fuel line bracket or a cooling shroud, that’s where you look. Section 5 is drive train, Section 6 the cab, Section 7 controls. The hydraulic circuits (Section 8) and hydraulic components (Section 9) are separate – keep that straight when you’re ordering a pump or a cylinder rebuild kit. Section 10 is electrical – wiring harnesses, switches, and controller parts for these models. Section 11 decals, Section 12 recommended spare parts. End with a full part number index. No guesswork, just factory data.

Engine and Attaching Parts – What You Get in Section 4

Section 4 is where you find the engine mounting brackets, exhaust components, and cooling system parts specific to the diesel engine that JLG used on these platforms. If you need an air filter housing or a fan belt tensioner pulley, the exploded diagram shows every bolt and bracket with a corresponding part number. The manual is dated November 25, 2014, revision L – so it includes all updates up to that date. That’s 11 revision letters from A to L (original issue in 2007, added 40.8/40.9 models in 2010). You can trace which parts changed across serial number breaks. The effectivity page is right up front – check it before ordering.

Section 10: Electrical – Wiring and Component Breakdown

Section 10 covers the electrical system: harness routing, control modules, dash switches, battery cables, and the connectors. Look up a part number for the joystick controller or the lift/lower solenoid. This is not a wiring diagram – it’s a parts catalog – but the exploded view shows each electrical component stripped off the harness with its JLG part number. If you’re replacing a damaged connector or a whole harness, you need this catalog to get the exact replacement. Aftermarket catalogs often group several harnesses into one ambiguous part number – not here. Each wire assembly has its own listing.

Why OEM Factory Parts Catalogs Beat Aftermarket Reprints

I’ve seen shops waste two days because the aftermarket “compatible” part had a bolt pattern that was 2 mm off. JLG’s own catalog lists every part by the number stamped on the original casting. The PDF is a direct image of the factory printed manual – no re-typeset errors, no blurred numbers. Look at the difference: an aftermarket “parts catalog” for a 3512PS might group all boom cylinder seals into one line. This manual gives you separate seal kit numbers for the lift cylinder and the extend cylinder because they are different sizes. That’s the kind of detail that keeps a rental machine on the job instead of in the shop. For reference, the Automotive Industry Overview standards for equipment documentation follow similar logic – original manufacturer data eliminates variation. If you’re working on a JLG 3509PS, the same accuracy applies. Also check Automotive Industry Overview for context on why lift equipment manufacturers control their part numbering the way they do.

Audience Fit: Who Needs This 518-Page Manual

This is for the tech or shop owner who has a JLG 3508PS, 3509PS, 3512PS, 3513PS, or 4008PS in the fleet. Maybe you’re rebuilding a used machine for resale, or you’re a rental yard with 20 of these things. Home garage guys who like to tinker with lifts – yes, you too, but know this: the manual does not contain service procedures, torque specs, or troubleshooting steps. It’s a parts catalog. That means exploded diagrams, part numbers, and quantities. If you need to order a hydraulic fitting for the outrigger circuit on a 4008PS, Section 1 Figure 1-4 or 1-5 shows the outrigger installation. Cross-reference with the part number index in the back. The index alone saves hours of flicking pages – it lists every part number alphabetically with the figure and reference number. Keep this PDF on your shop tablet.

Frequently Asked Questions

Does this manual include torque specifications for assembly?

No, this is a parts catalog, not a service manual. It lists part numbers and quantities only.

How do I find the part number for the hydraulic pump on a JLG 4008PS?

Go to Section 9, Hydraulic Components. Find the figure for the pump assembly (noted as “Hydraulic Pump” in the table of contents). The exploded view will show each component with a callout number. Look up that callout in the parts list below the figure. The part number index at the back of the manual also cross-references every part number to the figure and reference number. For a 4008PS built after SN 1160006866, check the effectivity page to see if any revisions apply – this catalog is revision L and covers machines up to that serial number range.

Can I use this catalog for a 4012PS or 4017PS?

The cover lists 3508PS, 3509PS, 3512PS, 3513PS, 4008PS, 4009PS, 4012PS, 4013PS, 4017PS, and Agrovector 40.8/40.9. So yes, the 4012PS and 4017PS are included within this same manual. However, verify your machine’s serial number against the effectivity page because some figures apply only to specific SN ranges. If your 4017PS falls outside the prior-to-SN range, you may need a later revision.

Is this a factory original PDF or a reprint?

It is the original factory OEM PDF as released by JLG in 2014. No scans, no photocopies, no third-party reformatting. The page count is exactly 518 pages.
