Lull 522 1998 Parts Catalog

This is the factory parts catalog for the Lull 522 1998 Parts Catalog. If you are rebuilding the transmission or chasing a hydraulic leak, this is the book you need. Not a reprint from some third-party that guessed the part numbers. This is the OEM document – 120 pages of exploded views and part numbers that match what Lull actually installed. Page 3 of this manual gives you the Drive Train Breakdown, covering the Perkins engine, Hurth front drive axle, and transmission case groups. Page 4 lists the general information and abbreviations you need to read the parts lists correctly.

Lull 522 1998 Parts Catalog: What’s Inside

You get the full table of contents. Every assembly from the Drive Train (Perkins) to the Cab Heater Assy (Hot Water). The Transmission Case Group, Low Speed Shaft Group, Forward Shaft Group, Reverse & Second Shaft Group, Output & Third Clutch Group – all broken down with part numbers. The 1998 edition also includes serial number splits for components like the Boom Extension Cylinder and Electrical Assy. If your machine falls between S/N 101-175 or 176+, you need the correct page. This catalog has that.

Transmission and Drive Train Breakdown

Your 522 has a Perkins diesel and a Hurth axle. The transmission is a powershift with multiple clutch packs. The catalog covers the Transmission Case Group Assy, the Converter Housing Group, and the Control Valve Group. Every seal, bearing, and clutch plate is listed. When you order a rebuild kit, you can cross-check the part numbers here. Aftermarket catalogs often lump all years together. This one separates 1998-specific components. The Low Speed Shaft Group has different part numbers than later models. Do not trust a generic list.

Engine and Hydraulic System Coverage

The Engine is covered in the Drive Train Assy (Perkins) section. But the catalog also includes Radiator & Transmission Oil Cooler, Throttle, Air Cleaner, Exhaust, and Engine Cover assemblies. For hydraulics, you get the Pump Suction-Return, Hydraulic Steering Brake & Diff Lock, and the entire boom and carriage hydraulic circuits. The Telescopic Boom Assy and Boom Hydraulic Assy show every fitting and cylinder part. If you need to replace the Frame Tilt Cylinder, the part number is listed with its seal kit.

Aftermarket Parts Catalogs: Why They Risk Your Job

I have seen techs order a seal kit based on a third-party PDF, only to find the snap ring groove is the wrong size because the catalog combined S/N ranges. The 522 has at least three different boom extension cylinder designs depending on serial number: the Boom Extension Cylinder Assy for S/N 101-175 and for S/N 176 and up have different part numbers. The Cab Assy has different part numbers for wiper motor and defroster depending on serial number range. Aftermarket reprints don’t show these splits. This OEM catalog includes those S/N breaks explicitly. The Electrical Assy is split between S/N 101-297 and S/N 298 and up. If you guess, you order the wrong harness. Over 120 pages of verified factory data. Use the Lull 522/522/4/622/622/4/824 Service Manual for repair procedures, and the Lull 522/522/4/622/622/4/824 Operators Manual – Factory Specs for daily operation. For older telehandlers, the Lull L-812 1983 Parts Catalog – OEM Factory Parts Breakdown is also available.

This catalog is used across the Automotive Industry Overview as a reference for telehandler parts. The Automotive Industry Overview provides context on why OEM documentation matters.

Can I use this manual for a 1997 Lull 522?

No. The 1998 version has specific part numbers and updates. Always match the year and serial number range.

What if I can’t find a part number in the catalog?

First, check the serial number range on the Machine Information Page. The manuals are serial-number-specific. If the part is not listed, it may be a superceded number – you need to cross-reference with Lull’s service bulletins. Some components like the Boom Extension Cylinder have different assemblies for S/N 101-175 vs 176 and up. Always verify. That’s why this 120-page factory book is critical; aftermarket catalogs often combine all years into one list and you get the wrong seal kit.
