Liebherr LTM 1090 2010 Parts Catalog

I’ve been inside more cranes than I care to count. When you’re tracking down a part for a Liebherr LTM 1090 2010 Parts Catalog, you don’t have time to sort through third-party listings that might be wrong. This catalog is 1342 pages of factory-issued part numbers, straight from Liebherr. No translation errors, no “close enough” substitutions. That’s the difference between a job that ships on time and a crane sitting dead on the pad.

Liebherr LTM 1090 2010 Parts Catalog: What’s Inside

Every section in this catalog is built around a specific assembly group. The table of contents lists exactly where to find each component. Need the Engine group? Look for “DIESEL ENGINE INSTALLATION” (91 51 528 08) and “DIESEL ENGINE, PRE-ASSEMBLED” (96 46 965 08). The Fuel system is covered under “FUEL FILTER PRE-ASS.” (96 31 491 08) and “FUEL TANK CPL.” (91 46 236 08). Each one takes you to exploded diagrams with item numbers that match the numerical index. You don’t need to guess which O-ring fits which line – the catalog gives you the exact part number.

I’ve seen guys order a “hydraulic pump” only to get the wrong displacement because they used an aftermarket parts list. This catalog breaks down the HYDRAULIK PUMP ASSEMBLY (96 32 069 08) and the separate PUMP ASSEMBLY (96 31 088 08) so you can order the right one. The index lists every item number with its page and position. That’s 1342 pages of reference material – no fluff, no reprints, no generic drawings.

What Does a 1342-Page Parts Catalog Give You?

Three things: accuracy, traceability, and time. Accuracy because every part number is verified by Liebherr’s own engineering. Traceability because the catalog includes assembly numbers like “LTM 1090-4-1-007” – you can match that to the machine’s serial plate. Time because you aren’t flipping through generic catalogs or calling five suppliers to check fitment. You open the PDF, find the group, pull the number, and order.

One example: the STEERING MECHANISM (91 23 230 08) and the STEERING HYDRAULICS (91 50 144 08) are separate entries. If you order a steering box without checking the hydraulic sub-assembly, you’ll be chasing leaks. The catalog shows you exactly which hoses, fittings, and seals belong to each group.

3 Systems You Can’t Afford to Misorder

1. Cooler Installation (91 46 233 08) – The hydraulic cooler, its drive, and the air cooler pre-assembly are all listed individually. Mixing up the cooler for the water radiator (96 30 986 08) is a common mistake. This catalog keeps them separate.
2. Axle Suspensions – Axles 1 through 4 all have their own entries with suspension components. Axle 1 with suspension (91 16 875 08) is different from Axle 2 (91 16 896 08). Pre-assembled axle units (like 96 27 512 08) include the full hub and brake assembly.
3. Electrical Equipment – The catalog includes wiring lists for the eddy current brake (96 27 767 08) and the electric slewing sensor (91 43 393 08). If you’re chasing a short in the Telma retarder, you need the “EL.EQUIPMENT TELMA” (91 56 473 08) section.

OEM Documentation: Why Aftermarket Catalogs Fail

I’ve been burned by third-party parts listings that use a generic photo and hope the part fits. Liebherr’s own catalog uses the same part numbering system as the factory. Every bolt, every seal, every bracket has a Liebherr item number. The catalog even includes the German text as the binding reference – so if there’s a discrepancy between languages, the German version wins. That’s the level of precision you need when a single wrong bolt can cost you a day of downtime.

When you’re sourcing parts for a crane that weighs 40 tons, guesswork isn’t an option. If you want to understand the broader context of heavy equipment parts, the Automotive Industry Overview on Wikipedia gives a good background on supply chains. But for the actual part numbers, you need the factory document. I’ve seen Automotive Industry Overview cited in discussions about component standardization – but that doesn’t replace the Liebherr-specific data in this catalog.

Hydraulics and Steering: Part Numbers That Matter

The catalog has multiple entries for hydraulics: 96 21 301 08, 96 21 303 08, 96 21 305 08, and 96 21 306 08. Each one covers a different sub-system. The steering hydraulics (91 50 144 08) is separate from the remote steering pre-assembly (96 59 192 08). If you’re replacing a hose, you need to know which hydraulic circuit it belongs to. The exploded views show every fitting and its orientation.

I’ve had techs tell me they “just ordered a pump” and ended up with the wrong shaft key. The catalog lists the clutch assembly (96 18 981 08) and the pump assembly separately, so you can see the full drive train. That’s the difference between a job that takes two hours and one that takes two days.

Frequently Asked Questions

Does this catalog include torque specifications?

No. It’s a parts catalog, not a repair manual. You’ll need the service manual for torque values.

How do I find the right part number for a hydraulic pump assembly?

The catalog is organized by assembly groups. Locate the section “HYDRAULIK PUMP ASSEMBLY” (item 96 32 069 08) in the table of contents. Each part is illustrated with exploded views and item numbers. Cross-reference the numerical index at the back to confirm. I’ve used this method hundreds of times — it’s accurate. The index also lists the page number, so you can flip directly to the drawing. If you have the old part number, check the alphabetical index by description — it’s all there. I’ve never had a wrong part using this method.

This is the kind of documentation that keeps a shop running. If you’re working on a Liebherr LTM 1090, you need the factory part numbers, not someone’s best guess. Access the factory manual and get the right part the first time.
