JLG 266, 307, 26.6, 30.7 2014 Parts Catalog – Factory OEM Parts Manual

You’ve got a JLG telehandler torn down on the shop floor – maybe a 266, a 307, a 26.6, or a 30.7. The part you pulled off has a worn seal, a cracked housing, or a stripped thread. Now you need the exact replacement, not a “close enough” aftermarket guess. That’s where this JLG 266, 307, 26.6, 30.7 2014 Parts Catalog earns its keep. 370 pages of factory-issued exploded views and part numbers. No reprints, no scanned blurs – this is the original OEM file from JLG. I’ve been turning wrenches for 28 years, and I’ve seen more wrong parts ordered from misinterpreted diagrams than I care to count. This book stops that.

370 Pages of OEM Parts Data

Thickness isn’t everything, but when a manual packs 370 pages of structured content, it means every nut, hose, and bracket gets its own callout. Section 1 covers Frame & Attaching Parts – Figure 1-1 through 1-3 give you the shrouding, cab mirrors, axle and fender installation. You want the right cover for a 266 LoPro? It’s in there. The boom sections? Section 2 takes you through the first and second boom sections, plus the quick switch and JD Quick Attach. Each figure has a parts list with JLG part numbers, quantities, and reference notes. You don’t need to interpret a generic drawing – this is the same document JLG dealers use.

Section 5: Drive Train – Axle Breakdown

Front and rear axles are laid out in nineteen figures. Figure 5-1 through 5-19 cover everything from the housing, bevel gear set, differential, double U-joint, brakes, wheel hub, final reduction, drive shaft, tires, and rims. If you’re rebuilding a front axle on a 307, you can pinpoint the exact bearing race or seal without pulling the whole assembly apart and measuring. That saves hours of downtime and prevents ordering the wrong part. I’ve seen guys order a whole carrier because they couldn’t ID the inner pinion bearing – this manual eliminates that.

What Does This Parts Catalog Cover?

Twelve sections: Frame & Attaching Parts, Boom, Attachments (buckets, forks, bale handler, concrete bucket), Engine & Attaching Parts (Deutz engine, fuel tank, radiator, air cleaner, exhaust), Drive Train, Cab (assembly, interior, seat, windows, door, wiper, air circulation), Controls (joystick, steering column, accelerator, brake pedal), Hydraulic Circuits (supply, dump, front drive, steer select, service/park brake, lift cylinder, crowd, tilt, auxiliary function, rear outlet), Hydraulic Components (cylinders, main control valve, front drive motor, hydrostatic pump, tank, implement pump, diverter valve), Electrical (harnesses, PWM valve controller, LMIS, LSI switch), Decals (frame, boom, cab, machine specific for 266, 307, 26.6, 30.7), and Options (hitch kits, automatic hitch, hydraulic hitch, front cab glass). That’s every system you’ll touch during a rebuild or repair.

Use This Catalog for Accurate Parts Ordering

Ordering a part for a 26.6 LP? Flip to Section 11 – Figure 11-5 shows the exact decal placement and part numbers. Need the hydraulic tank assembly for a 30.7? Figure 9-9 lists the tank, cap, filter, and fittings with JLG part numbers. The index at the back lets you cross-reference part numbers to figures. I always keep a printed copy next to the computer – faster than scrolling through a PDF, but the PDF is searchable too. Pair this with a repair manual for torque specs and procedures, and you’ve got a complete shop setup.

Source Validity: Factory OEM vs Aftermarket

Aftermarket parts catalogs often re-label JLG parts with generic numbers or omit supersessions. This manual is the real thing – JLG document number 3126025, revised April 3, 2014. It carries the effectivity history from original issue in 2005 through revision I in 2014, covering all model variants: 266, 307, 266 LoPro, 26.6, 30.7, and 26.6 LP. That means you’re getting the same data JLG uses for warranty claims and dealer orders. I won’t trust a parts manual that doesn’t have a manufacturer’s part number on every page. This one does.

Real-World Use Case: Hydraulic Cylinder Rebuild on a 307

You’ve got a lift cylinder leaking. Instead of pulling the entire cylinder and trying to match an O-ring from a kit, open Figure 9-1. It shows the lift cylinder with every seal, wiper, snap ring, and port – each with a JLG part number. Order the seal kit direct. No guessing. That’s the difference between a two-hour job and a two-day wait for the wrong parts. For the DIY owner maintaining a 266 on a farm, this catalog pays for itself the first time you avoid a mismatched bucket pin.

FAQ

Does this manual include repair procedures or only parts?

Only parts. This is a parts catalog – exploded diagrams and part numbers. You need a separate service manual for removal, installation, and torque specs.

Will this work for a 2015 JLG 30.7?

Yes. The catalog covers up to 2014 production, and JLG typically uses the same part numbers for several years after. Check the effectivity page – revision I (2014) includes all models through that date. For a 2015 machine, cross-reference any supersessions by calling JLG or using their online parts lookup. The diagrams are still accurate for identification.

Stop chasing parts through generic databases. Access the Factory Manual and get the OEM part numbers you can trust.
