Lull 844B 1998 Parts Catalog – OEM Factory Parts Manual

I’ve seen it happen a hundred times. A shop orders a part from a generic cross-reference, gets it in hand, and it’s wrong. The bolt pattern doesn’t line up, the seal is a different durometer, or the spline count is off. That’s a wasted day and a pissed-off customer. If you’re turning wrenches on a Lull 844B, you don’t have time for that. You need the actual factory parts breakdown – the one that shows you exactly which revision fits your serial number. This 1998 Lull 844B Parts Catalog is that document. 294 pages, straight from the OEM. No reprints, no scanned copies of a poor photocopy. This is the original factory file.

Let me walk you through what’s inside, because the Table of Contents tells you exactly what you’re getting. Section 1 is Drive Train – covers the radiator, transmission oil cooler, throttle assembly, air cleaner, exhaust, and the transmission disconnect assembly. Section 2 is Transmission and Axles. That’s where you’ll find the Funk transmission breakdown for machines with serial numbers 101-530, and the ZF transmission breakdown for serial number 531 and up. There’s a separate axle breakdown too. If you’ve ever tried to figure out which clutch pack goes where in a Funk, you know how critical this is.

Section 2: Transmission and Axles – Funk vs ZF Breakdowns

You need to know the exact transmission your 844B has. The manual splits it by serial number – Funk for early machines, ZF for later. The Funk section alone runs pages 2.5 through 2.17, covering main case assembly, output retainer, output shaft, three clutch stages, front cover, input shaft, valve control, pump, drive plate, converter, and parking brake & yoke. Each sub-assembly has an exploded illustration with part numbers. No guesswork. For the ZF transmission, you get converter & flex plate, gearbox housing, input group & layshaft, and clutch assemblies for forward, reverse, 1st, 2nd, and 3rd gear. If you’re rebuilding either transmission, this is the only reference you should trust.

Boom and Transfer Hydraulics: Section 5 and 6

Hydraulic leaks on a telehandler are dangerous. A blown hose at full extension can drop the load. Section 5 covers Boom and Transfer Hydraulics. Section 6 covers Lower Hydraulics. Section 7 covers Control Hydraulics. Each section breaks down the valve bodies, cylinder seals, and hose routing. The parts catalog gives you the OEM part number for every O-ring and cartridge valve. You won’t be searching through a generic cross-reference hoping it seals. You’ll order the correct part, install it, and move on.

Section 9 Electrical – Wiring Harness Part Numbers

Electrical gremlins are the worst. Section 9 covers the entire electrical system – harnesses, switches, sensors. The manual lists each connector and its factory part number. If you’re dealing with a no-start or a flickering dash light, you can trace the circuit and order the exact harness segment. Automotive Industry Overview – that’s the broader context, but for real work you want the specific OEM diagram.

Serial Number Splits: Why They Matter

Lull changed parts mid-production. This manual accounts for that. Look at the Air Cleaner Assembly in Section 1: three different serial number ranges for Deere engines – S/N 101-558, S/N 559-1139, S/N 1140 Thru. If you order an air cleaner element for a machine with serial number 600 using the part for a 400, it won’t fit. The manual tells you which page to look at based on your actual machine serial. That’s factory-level detail you won’t find in aftermarket catalogs. Automotive Industry Overview – but again, you don’t need an overview, you need the specific part number for your 844B.

Numerical Index – The Quickest Way to Find a Part

The last section of this 294-page manual is a numerical index. If you have a part number from an old part, you can look it up in the index and it tells you which page and which illustration it appears on. This saves hours of thumbing through sections. I’ve used this feature myself when a customer brings in a box of old parts and wants to identify what they’re from. Without this index, you’re stuck flipping through 11 sections blind.

Is this manual specific to the Lull 844B model year 1998?

Yes.

The transmission section shows different breakdowns for the Funk and ZF. Are the part numbers clearly separated by serial number ranges?

Absolutely. The manual splits the Funk transmission into two serial number ranges (101-530 and 531-thru) with separate pages. The ZF transmission breakdown starts at page 2.18. Each sub-assembly page lists the part number, description, and quantity. You won’t accidentally grab a part for the wrong transmission. The same careful separation applies to the axle breakdown, differential carrier, and even the throttle assembly – Deere vs. Cummins engine options are called out.

I’ve been turning wrenches since before torque sticks were a thing, and I’ve seen guys waste entire afternoons because they used a generic parts list from a third-party website. Don’t be that guy.
