JLG G5-18A, 2505H, Agrovector 25.5 2013 Service Manual – Factory Specs for Heavy Equipment

I have seen a rookie snap a bolt because he guessed the torque on a JLG telehandler. That guess cost the shop a few hundred bucks and a day of downtime. If you work on a G5-18A, a 2505H, or an Agrovector 25.5, you do not get to guess. You need the JLG G5-18A, 2505H, Agrovector 25.5 2013 Service Manual open on the bench. This is the original factory document, 180 pages, issued May 9, 2013, revision A. It covers serial numbers from 0160053000 and after plus specific earlier units. No aftermarket reprint – this is the same PDF JLG techs use.

Torque Specs and Fluid Capacities – Section 2

Section 2 of the manual gives you the torque charts you need. Page 2-3 contains the SAE and metric fastener torque charts plus the hydraulic hose torque chart. I do not care how long you have been turning wrenches – use the spec. Fluids and capacities are listed on page 2-4. You get travel speeds, hydraulic cylinder performance specs, electrical system data, and engine performance numbers. Skip the torque chart and you are asking for a hydraulic leak or a stripped thread. This chapter keeps your repair from coming back on a hook.

Boom Wear Pads: Inspection and Lubrication – Section 3

The boom is the heart of these machines. Section 3 walks you through two-section boom system service. You get complete boom removal and installation steps. Wear pads require inspection and lubrication – the manual tells you how to measure them and what lubricant to use. Page 3-8 covers the boom prop if equipped, and the emergency boom lowering procedure starts on page 3-9. That procedure lists the equipment you need and the exact steps to get the boom down safely when the hydraulics die. Do not skip the safety information at the start of this section.

Replace Cab Components Using Factory Procedures – Section 4

The cab chapter handles a lot of interior work. Section 4 covers the operator cab description, steering wheel and column replacement, brake pedal and valve, joystick replacement, windshield wiper and washer assemblies, and the heater/air conditioning system. If you have ever fought a joystick that will not center, the factory procedure shows you the disassembly order and torque values for the mounting bolts. Cab removal and installation procedures are also detailed. With the OEM document you will not break a plastic trim piece prying in the wrong spot.

5 Sections Covering Axles, Drive Shafts, and Brakes

Section 5 is thick with content. Axle assemblies, drive shafts, wheels and tires, steering angle adjustment, brake disc inspection, and towing a disabled machine. The axle specifications table gives you the numbers for internal service. Drive shaft inspection and maintenance are spelled out in sequence. Brake disc inspection on page 5-8 tells you the minimum thickness and wear limits. If you do a brake job, you need that spec. Towing procedure includes an equipment list and steps – critical if the machine is dead in the field.

Transmission Description and Service – Section 6

Section 6 covers the transmission assembly. It starts with component terminology and safety information, then gives the transmission description. Removal and installation steps are included. This section alone can save you from pulling the wrong component. For background on how these transmissions work, check Manual Transmission and Manual Transmission. But for the actual repair, you need the factory service manual.

What Makes OEM Documentation Better Than Aftermarket?

I have seen aftermarket manuals list a generic torque chart for “similar equipment.” That is how you end up with a loose axle bolt. This manual is printed by JLG, for JLG machines. The torque values, fluid capacities, and tolerances are measured at the factory. Page 2-3 is not a suggestion – it is the spec. Aftermarket manuals often skip safety decal locations and the “Do Not Operate” tag procedures. Section 1 in this manual covers all safety practices, including personal hazards and equipment hazards. If you are a professional mechanic, you know liability follows incorrect repairs. Use the OEM document. Pair it with the JLG G5-18A, 2505H, Agrovector 25.5 2014 Parts Catalog – OEM Specs for complete parts lookup.

Frequently Asked Questions

Does this manual cover the Agrovector 25.5 model?

Yes. It covers G5-18A, 2505H, and Agrovector 25.5 with specific sections where differences occur.

What torque values are listed in the torque charts?

The torque charts include SAE and metric fastener torque values plus hydraulic hose torque values. Page 2-3 has the full charts. You get values for grade 5, grade 8, and metric class 8.8 and 10.9 fasteners.

Can I use this manual for a 2014 model JLG G5-18A?

The manual covers serial numbers from 0160053000 and after. While the 2013 document covers most components, JLG releases updates. For 2014 models, consider the JLG G5-18A 2505 2014 Parts Catalog – OEM Factory Specs for parts, but this service manual remains accurate for the base structure. Also check the JLG G5-18A, 2505H, Agrovector 25.5 2013 Parts Catalog – Factory Specs for part numbers. Use both for a complete repair.

How do I access the emergency boom lowering procedure?

Section 3, page 3-9, covers the emergency boom lowering procedure with required equipment and step-by-step steps to lower the boom manually if the hydraulic system fails. Follow the safety warnings first.
