JLG G5-18A, 2505H, Agrovector 25.5 2014 Parts Catalog

You are a technician or an owner who has been burned by ordering the wrong hydraulic seal for a JLG G5-18A, 2505H, Agrovector 25.5 telehandler. Maybe you matched a part number from a third-party website and it didn’t fit. Weeks of downtime, restocking fees, and a machine that is still dead. I have been there. That is why I only trust the factory Parts Catalog when I am pulling numbers for a rebuild. This is the OEM book, JLG part number 31200725, revised January 22, 2014. It covers serial numbers 0160053000 and after, plus a list of specific earlier units. If you want to get the right part the first time without hand-measuring every O-ring, you need this document on your workbench.

Frame & Attaching Parts: Section 1 Breakdown

Section 1 covers four figures: Figure 1-1 Frame & Attaching Parts, Figure 1-2 Covers, Figure 1-3 License Plate Holder Installation, and Figure 1-4 Hitches. You get exploded views with callouts for every bracket, bolt, and hitch plate. When you are rebuilding a front-end collision or swapping a hitch receiver, these diagrams save you from calling the dealer and waiting on hold. The manual uses JLG’s own part numbering system, so you can cross-reference directly with your local JLG distributor. You will not find a better source for frame components because this is what the factory assemblers used on the line.

What Does the Hydraulic Circuits Section Cover?

Section 8 is a monster: 11 figures covering everything from the Supply Circuit (Figure 8-1) to Auxiliary Hydraulics Pressure Relief (Figure 8-11). Every hose, fitting, and valve is illustrated. If you are troubleshooting a boom that drifts or a steer-select that sticks, you need the exact part numbers for the pilot select valve (Figure 9-14) and the steering select valve (Figure 9-13). The manual also breaks down the Auxiliary Hydraulics (Figure 8-9) and Rear Auxiliary Hydraulics (Figure 8-10) separately, which matters when you are adding a third-function valve. Page 3 (Effectivity Page) shows you which revision level your machine matches. Do not rely on a scanned copy from a forum – this is the genuine 2014 D-revision file.

3 Reasons to Choose OEM Documentation

First: aftermarket parts catalogs often combine models or drop figures to save paper. This manual keeps Figure 2-1 Boom Assembly – Components and Figure 2-2 Boom Assembly – Pads & Shims as separate pages, so you can order wear pads and shims without guessing thickness. Second: OEM torque specs and hardware grades are listed in the illustrations. Third: the Part Number Index at the end of 302 pages lets you look up any number alphabetically. You waste zero time flipping through sections. That is the difference between a job that pays and a job that costs you money.

Get the Right Part Numbers for Your Boom Assembly

Section 2 covers the boom in four figures: assembly components, pads & shims, quick coupler, and universal quick coupler. If you have a 2505H with a worn extend cylinder, you need the cylinder breakdown in Figure 9-2 Extend/Retract Cylinder from Section 9. The manual lists every seal kit part number. I have rebuilt these cylinders using aftermarket seal kits that leaked within fifty hours. Buy the JLG kit. The part number is in this catalog. JLG G5-18A 2505H Agrovector 25.5 2013 Service Manual – Section: Cab gives you the service procedures to install those parts. The parts catalog is not a repair manual – it is the parts list. Use both.

Electrical Wiring: 19 Harness Diagrams in Section 10

Section 10 is the electrical section: 19 figures including separate harnesses for the engine compartment, boom and frame, cab, work lights, and drive lights. If you are chasing a short in the cab roof harness (Figure 10-11), the diagram shows each wire color and connector position. There is also a separate Beacon Worklight Harness (Figure 10-14) and LSI Boom Sensor Harness (Figure 10-16). You can order the exact harness part number instead of splicing and hoping. I have seen too many homemade harness repairs cause fires. Use the factory part – it is the only safe option.

This manual is 302 pages of pure factory data. It is not a reprint or a generic copy. The PDF is scanned from the original JLG publication, so the illustrations are sharp and the part numbers are legible.

If you are new to construction equipment, understand that Automotive Industry Overview gives a broader context, but this catalog is the specific tool you need on the bench. Automotive Industry Overview is a general reference; this is a machine-specific bible.
