JLG G5-18A, 2505H, Agrovector 25.5 2013 Parts Catalog

Ordering the wrong part because you guessed the O-ring size or pulled a number off some third-party website? I’ve seen it cost a shop five hours and a customer a blown head gasket. That’s why I keep a factory parts catalog on the bench, not a reprint or a PDF cobbled from forum posts. This JLG G5-18A, 2505H, Agrovector 25.5 2013 Parts Catalog is the genuine OEM document – 134 pages of exploded diagrams, part numbers, and the exact fasteners JLG used at the factory. No guesswork. No sifting through generic listings. Just the data you need to order the correct valve cover gasket, oil pan bolt, or fuel injector the first time.

Section 1 ENGINE: What the Factory Put Together

The manual opens with a full breakdown of the TD 2.9 L4 engine. Fifty-seven figures cover everything from the dipstick (Figure 1-1) to the special tools list (Figure 1-57). Each figure has an exploded view with callouts. You get the JLG part number right next to the fastener. The valve mechanical cover (Figure 1-9) shows every bolt, gasket, and retainer. If you’re rebuilding the top end, you need that diagram. It tells you which bolts are replaceable and which washers are single-use. No aftermarket catalog gives you that level of specificity.

Valve Mechanical Cover: Figure 1-9

That’s Figure 1-9 on page 1-18. The valve cover on the TD 2.9 L4 has a specific bolt pattern and gasket design. The manual shows you the exact orientation of the breather line and the heat protecting shield (Figure 1-10). Trying to reuse that gasket because you thought it looked fine? Bad idea. The factory lists the gasket as a separate part – no guesswork. Order the right one from the part number in the catalog. That’s how you keep oil off the exhaust manifold and avoid a shop fire.

Fastenings and Torque: Figure 1-8

Figure 1-8 covers fastenings – the bolts, nuts, and washers that hold the engine assembly together. I don’t care if you’re a weekend wrench or a shop foreman, torque matters. The catalog doesn’t list torque values (that’s in the service manual), but it gives you the correct bolt grade and thread pitch. Pair this catalog with the service manual – I recommend the JLG G5-18A 2505H Agrovector 25.5 2013 Service Manual – Section: Cab”>JLG G5-18A 2505H Agrovector 25.5 2013 Service Manual – Section: Cab – and you’ll have both the part number and the torque spec. No more stripped threads because you grabbed a generic Grade 5 bolt.

3 Reasons to Choose OEM Documentation

First, the part numbers match JLG’s inventory system. You call the dealer, give them the number from the catalog, and the part arrives correct. Second, the exploded views show the assembly sequence – you can see how the oil cooler (Figure 1-14) stacks with the oil filter assembly (Figure 1-15). Third, the JLG G5-18A 2505 2014 Parts Catalog”>JLG G5-18A 2505 2014 Parts Catalog covers the next model year, but this 2013 catalog is specific to the T4f engine. Don’t mix years. The 2014 version might have a different fuel rail (Figure 1-22). Stick with the correct year.

Aftermarket parts catalogs are trash for this. They merge multiple engine revisions into one drawing. You end up with a part that doesn’t fit because the fuel supply pump (Figure 1-19) changed mounting brackets mid-production. This OEM catalog captures the exact configuration for serial numbers 0160053000 and after, including specific units listed on the effectivity page. That’s the kind of detail you pay for when you buy factory docs.

Audience Fit: Who Needs This Parts Catalog?

If you own a JLG G5-18A, 2505H, or Agrovector 25.5 and you’re doing anything beyond an oil change, you need this. The JLG G5-18A 2505H Agrovector 25.5 2014 Parts Catalog”>JLG G5-18A 2505H Agrovector 25.5 2014 Parts Catalog exists, but this 2013 edition matches the engine build for machines built before September 2013. The coolant pump (Figure 1-30), thermostat (Figure 1-33), and EGR module (Figure 1-37) are all specific to the T4f emissions package. If you’re a home mechanic pulling a turbocharger (Figure 1-38), you want the correct oil feed line part number. One wrong fitting and you’re buying a new turbo.

Professional shops: this catalog saves billable time. Instead of calling the dealer and waiting on hold, you read the part number from the screen and send the apprentice to the parts counter. The Automotive Industry Overview shows how even minor parts mismatches create downtime. Don’t be that shop.

Does This Manual Cover the Fuel System?

Yes. Figures 1-17 through 1-25 detail the entire fuel system: high pressure pump, injectors, supply pump, filter, prefilter, rail, high pressure pipes, and fuel lines. Each component has its own figure with separate part numbers. The control unit (Figure 1-29) and glow plugs (Figure 1-52) are also listed. If you need the intake pipe or charge air elbow (Figures 1-26 to 1-28), those are there too. The wastegate actuator? Not in this catalog – that’s in the turbocharger section, but the turbo itself is Figure 1-38 with a separate callout for the actuator if it’s a separate part.

One thing I appreciate: the recommended spare parts list at the back. It groups the high-failure components like gaskets, seals, and filters. You can stock the shelf with the right parts before the machine breaks. That’s proactive maintenance, not reactive panic.

What You Won’t Find Here

This is a parts catalog, not a service manual. It does not contain torque specifications, removal procedures, or diagnostic flowcharts. For that, get the service manual from Automotive Industry Overview or the OEM source. But if you’re ordering parts for an engine rebuild, you want this catalog open on one screen and the service manual on another. The part number index at the back (PART NUMBER INDEX) lets you cross-reference a bolt you pulled out of a bin.

Can I use this catalog for a 2505H with a different engine serial number?

Check the effectivity page. This catalog covers serial numbers 0160053000 & after including 0160051045, 0160051047, 0160051049, 0160051194 & 0160051359. If your engine is outside that range, you need a different revision.

Are the part numbers still available from JLG?

Most are. JLG supports these models. But some parts get superseded. Use the part number from the catalog to check with your dealer. They’ll tell you if it’s been replaced by a newer number.

Bottom line: if you’re tearing into a TD 2.9 L4 engine on a JLG G5-18A, 2505H, or Agrovector 25.5, this is the parts bible. Don’t rely on memory or scribbled numbers. Get the factory document. Access the Factory Manual.
