Lull 944E-42, 644E-42 2014 Parts Catalog

You ever order a part for a telehandler using an aftermarket number and end up with a bracket that doesn’t bolt to anything? I have. Chased a hydraulic fitting for half a day once because some third-party catalog had a swapped thread pitch. That’s why you need the actual Lull 944E-42, 644E-42 2014 Parts Catalog from the factory – not a scanned copy of a copy, not a PDF rebuilt by somebody who never touched a boom. This is the official JLG-published document, revision P, dated October 29, 2014, running 634 pages of exploded-view drawings and OEM part numbers. Covers serial number 17569 thru 20123 and 0160002514 to present. If you’re rebuilding a 644E-42 or a 944E-42, this is your parts bible.

Frame & Attaching Parts: Section 1 Content

Section 1 kicks off with main frame components for both models. You get separate figures for the 644E (prior to SN 0160048717, excluding 0160045421) and the 944E (prior to SN 0160041827). Page 28 covers the fender assembly – weldment, mounting hardware, all with JLG part numbers. If you’ve ever tried to match a fender support bracket without the illustration, you know the pain. This catalog saves you that.

Engine & Attaching Parts: Section 4 Detail

Section 4 is where the Engine lives. Mounts, isolators, cooling system components, and all the brackets that attach the powerplant to the frame. The manual breaks out engine pod installations for both models, with clear SN breakpoints. You’ll find the correct vibration isolator part numbers – not the ones that fit two years ago, but the ones that match your machine’s build date. Aftermarket catalogs lump all years together. This one doesn’t.

12 Sections of Factory Parts Data

Every major system gets its own section: Frame (Section 1), Boom (Section 2), Attachments (Section 3), Engine & Attaching Parts (Section 4), Drive Train (Section 5), Cab (Section 6), Controls (Section 7), Hydraulic Circuits (Section 8), Hydraulic Components (Section 9), Electrical (Section 10), Decals (Section 11), and Options (Section 12). Then a Recommended Spare Parts list and a full Part Number Index. That index alone is worth the access – you can look up any number and find the figure and item callout immediately.

Electrical System: Section 10 Coverage

Section 10 gives you the wiring harness diagrams and connector callouts for the 644E-42 and 944E-42. Not a schematic that shows circuit theory – this is a parts catalog, so you get the harness assembly part numbers, individual lead lengths, and terminal part IDs. When a wire chafes near the frame ground, you need the exact replacement harness pigtail. This catalog lists it. No guesswork, no calling the dealer and reading a faded sticker.

Effectivity Page: Why Revision History Matters

Look at page 3 of the PDF – the Effectivity Page. It tracks every revision from February 2005 through October 2014, letter A through P. If your machine was built mid-2012, you need the revision K or later data. This catalog includes all of them. Aftermarket “comprehensive” books often skip revision notes. That’s how you end up with a part that supersedes three times and nobody tells you. The factory book documents the change.

Audience Fit: Who Needs This Catalog

If you’re a shop owner tired of your techs burning billable hours chasing wrong part numbers, put this PDF on the shop tablet. If you’re a home garage mechanic trying to keep a 644E-42 running for your property, you need the exact bolt grade and washer thickness – this catalog gives you the JLG part, not a “universal” substitute. The boom sections alone (Section 2) show every weldment, roller, and chain sheave with OEM dimensions. No aftermarket website gives you that.

Source Validity: OEM vs Aftermarket Documentation

I don’t trust aftermarket parts books. I’ve seen them list a tie rod end for a 944E-42 that actually came from a different chassis. This catalog is direct from JLG – an Oshkosh Corporation company. The part numbers match JLG’s own system. If you cross-reference with the Lull 944E-42 Service Manual (2011), you’ll have both the repair procedure and the parts breakdown. That’s the right workflow. For the engine section specifically, the Lull 644E-42 944E-42 Illustrated Parts Manual – Section: Engine & Attaching Part is included here as part of the full book. And if you’re working on older iron, the Lull L-812 1983 Parts Catalog – OEM Factory Parts Breakdown covers that vintage.

For background on why OEM documentation matters in heavy equipment, check the Automotive Industry Overview – it outlines how manufacturers like JLG control their supply chain. Also see Automotive Industry Overview for more on parts traceability. But the bottom line is this: factory catalog, factory numbers, no reprints.

FAQ

Does this catalog cover my specific serial number?

Yes – SN 17569 thru 20123 and 0160002514 to present. Check your machine’s plate.

How do I verify a part number before ordering?

Use the Part Number Index in the back. Find your number, note the figure and item callout, then look up that figure to confirm the illustration matches your machine’s configuration. Pay attention to serial number breakpoints listed on each figure – the catalog notes which SN ranges use which parts. For example, the main frame for 644E changed at SN 0160048717. If you don’t check that, you’ll order the wrong lower frame weldment. The factory book makes it clear.
