JLG G5-19A, G6-23A 2014 Parts Catalog – Factory OEM

If you are turning wrenches on a JLG G5-19A, G6-23A 2014 Parts Catalog telehandler, you already know the parts catalog is the difference between ordering the right seal and making two trips to the dealer. This 2014 Parts Catalog runs 318 pages of factory exploded views and OEM part numbers – no condensed summaries, no guesswork. Every figure in this manual came off the same assembly line as the machine. I have watched guys lose half a day because they tried to cross-reference a hydraulic fitting from an aftermarket sheet. They end up with the wrong O-ring and a hydraulic leak in the cab. This catalog stops that cold.

Section 1 Frame & Attaching Parts – Where to Find Your Axle Components

Frame mounting hardware is often the first thing to get lost when you pull a telehandler apart. Section 1 covers Figure 1-1 Frame Shrouding & Trim, Figure 1-2 Fender Installation, and Figure 1-3 Axle Installation. Each figure lists every bolt, bushing, and bracket. The axle installation page (Figure 1-3) is critical – the torque specs on those axle-to-frame fasteners are not published in the owner’s manual. If you are replacing a front axle housing, you need that figure open on the bench.

Section 2 Boom – First and Second Boom Sections

The boom is the heart of any telehandler. Section 2 breaks down Figure 2-1 First Boom Section and Figure 2-2 Second Boom Section, plus the Quick Switch assemblies (Figures 2-3 and 2-4). The wear pad part numbers for the first boom section are different from the second – install the wrong one and you will have side play inside a year. This catalog gives you the exact JLG part number, not a “cross reference to a generic pad”.

3 Drive Axle Sections You Should Know

Section 5 – Drive Train – is the longest section in the manual, and for good reason. It contains 19 figures covering both front and rear axles: housing, bevel gear set, differential, double U-joint, brakes, wheel hub, final reduction, and steering cylinder. If you need a part for the front axle brakes (Figure 5-7) or the rear axle swivel housing (Figure 5-13), the exploded view shows the exact orientation of each bearing and seal. You won’t find this level of detail in a third-party reprint.

Why OEM Parts Catalogs Beat Aftermarket Summaries

Aftermarket catalogs often combine multiple model years into one chart and leave out revision letters. This manual is revision F, dated April 4, 2014, and includes the effectivity page showing all revisions from original issue in 2006. That matters. JLG updated the hydraulic quick switch assembly between revisions C and D – the part numbers changed. An aftermarket list might still show the old numbers. You end up ordering the wrong coupler block. Find the correct revision letter on page iii of the Table of Contents and match it to your machine’s serial number.

Does This Manual Cover the Electrical System?

Yes. Section 10 – Electrical – includes Figure 10-1 Electrical Installation, the engine harness (10-2), rear chassis harness (10-3), front chassis harness (10-4), PWM valve controller (10-5), roof harness, main harness, ground harness, and optional bucket shake switch. Every wire gauge and connector part number is in the figure callouts. If you are tracing a no-start condition on a G6-23A, the wiring diagram for the engine harness will save you from probing random pins.

Attachments: Buckets, Forks, and Carriage Configurations

Section 3 – Attachments – lists 11 figures covering carriages, buckets (including four-in-one and manure bucket), fork-mounted hooks, truss boom, side shift carriage, side tilt carriage, and fork-mounted platform. The part numbers for the bucket teeth on the general purpose bucket (Figure 3-2) are different from the four-in-one bucket (Figure 3-3). Mix them up and the tooth pin won’t align. This catalog gives you the exact tooth and adapter number.

Does this catalog include torque specs?

No. This is a parts catalog – it shows part numbers and exploded views, not torque values. You need the corresponding service manual for assembly torque.

Are the part numbers still current for 2025?

Some numbers may have supercessions. JLG revises parts regularly. The catalog uses revision F (2014) – always check the effectivity page against your machine’s serial. For the latest supercessions, contact a JLG dealer.

Will this work for a G5-19A built in 2008?

Yes, the catalog covers all production from original issue in 2006 through the 2014 revision. The effectivity page lists the serial number ranges for each revision. As long as your machine falls within the range for revision F, the part numbers are correct.

Can I use this to order seals for the tilt cylinder?

Yes. Figure 9-3 Tilt Cylinder in Section 9 – Hydraulic Components lists the seal kit part number. Every O-ring and backup ring is shown in the exploded view. Do not order a “generic” seal kit – the G5-19A tilt cylinder uses a different rod seal than the G6-23A. This catalog gives the exact kit number for each model.
