Lull 944E-42, 644E-42 2009 Parts Catalog

If you’re ordering parts for a Lull 944E-42 or 644E-42, you’re gambling if you don’t have the factory parts breakdown in front of you. I’ve wasted enough afternoons chasing wrong part numbers because someone pulled from a third-party site. This isn’t a reprint or a scan of a scan. It’s the original 2009 JLG publication – the same book sitting in dealership parts departments. 490 pages of exploded diagrams, part numbers, and revision history. No guessing which fastener goes where.

Section 4 covers Engine & Attaching Parts – five figures including Figure 4-1 Engine Mounting, Figure 4-2 Fuel System, and Figure 4-3 Radiator & Oil Cooler Mounting. Need to order a radiator bracket for a 944E-42 built between serial number 17569 and 20123? The figure and callout are right there. Page numbers change between revisions, but the manual includes an effectivity page listing every update from February 2005 through January 2009. That level of traceability matters when your machine is down and the distributor wants the correct revision level.

Section 1 – Frame & Attaching Parts

Main frame components, engine hood and skirt, fender assembly – all broken down with OEM part numbers. The manual uses a consistent Figure/Item numbering system. For example, Figure 1-1 Main Frame Components lists every bolt, bushing, and plate. You cross-reference that with your machine’s serial prefix to get the current part. No aftermarket catalog can match that specificity.

7 Systems Covered Across 490 Pages

This catalog isn’t just engine and frame. Section 2: Boom (including extend and retract chains – Figure 2-5 and 2-6). Section 3: Attachments (buckets, carriages, truss booms, fork positioning assemblies). Section 5: Drive Train (front and rear axles, ZF transmission with thirteen sub-figures). Section 6: Cab (heater, AC, glass, wipers). Section 7: Controls (brake, throttle, joystick valves). Section 8: Hydraulic Circuits (pumps, cylinders, slave cylinders – 28 figures). You won’t find this level of detail in a generic service manual. This is the parts bible for these machines.

Why Factory OEM Documentation Beats Aftermarket

I worked on JLG and Lull equipment for years. Aftermarket parts catalogs frequently use generic diagrams or mislabel components. This manual includes the exact Engineering Bill of Material (EBOM) used by Lull. The part numbers tie to JLG’s current inventory system. If you order a seal kit for a ZF transmission coupling group (Figure 5-21 through 5-24), you get the correct kit because the manual lists the Service Kit number on the effectivity page. Lull 944E-42 Service Manual (2011) pairs with this catalog for repair procedures, but for ordering, this is the only source you should trust.

Does This Manual Cover the Fuel System?

Yes. Figure 4-2 Fuel System details the fuel tank, lines, filters, and injection components. If you need the part number for a fuel line clamp on a 644E-42, the illustration shows it in context. Same for the air cleaner assembly (Figure 4-4) and exhaust system (Figure 4-5). Every system that bolts to the engine is covered.

Frequently Asked Questions

What models and serial numbers are covered?

Lull 644E-42 and 944E-42 with serial numbers 17569 through 20123 and 0160002514 & after. The effectivity page lists all revisions up to January 2009. Always check your machine’s serial number before ordering.

Is this a digital access or a paper manual?

Digital PDF. 490 pages. You can search by part number or navigate through bookmarked sections.

Can I use this to diagnose mechanical problems?

No. This is a parts catalog, not a service manual. It shows exploded views and part numbers. For repair procedures, torque specs, and hydraulic troubleshooting, get the Lull 644E-42 944E-42 Illustrated Parts Manual or the service manual. Mixing them is how you end up with a transmission in pieces and no assembly order.

How current are the part numbers?

The manual is the H revision, dated January 16, 2009. JLG may have superseded some parts after that date. But the part numbers in this catalog are factory-original. You can call any JLG dealer and they will recognize them. Avoid cross-references from third-party sites – they often point to obsolete or incorrect numbers. For older machines like the Lull L-812, you’ll want the Lull L-812 1983 Parts Catalog – OEM Factory Parts Breakdown which covers that era. Automotive Industry Overview is a broader field, but for Lull specifics, this manual is the authority. Automotive Industry Overview – not relevant here, but it’s worth knowing how these machines fit into the larger equipment industry.

Don’t waste time on aftermarket PDFs that omit figures or renumber parts. The factory manual from AutoRepairManuals is the same document used by Lull dealers. Access the Factory Manual and keep it on your tablet next to the toolbox. You’ll order right the first time.
