Liebherr 734, 724 2010 Parts Catalog

You’ve got a Liebherr 734, 724 2010 Parts Catalog sitting in the yard with a blown final drive or a leaky track tension cylinder. You pull up an online parts diagram from some third-party site and the numbers don’t match the tag on your machine. Sound familiar? That’s because aftermarket catalogs pull from old scans and leave out the supersessions. This factory print from Liebherr – 795 pages of exploded views, part numbers, and quantity lists – matches what came off the line. No reprints. No guessing. Just the original OEM data that Liebherr used when your machine was built. That’s the difference between a one-hour job and a three-week parts chase.

PR734L-724 LITRONIC and the Undercarriage Breakdown

Starting on the first page after the guides, you hit the PR734L-724 LITRONIC section – the core of this Parts Catalog. It breaks down the complete undercarriage: running gear assemblies (TRAIN DE ROULEMENT CPL.), left and right track frames, support rollers, guide wheels, and the chain tension system. Each exploded diagram comes with a position number, Liebherr part number, quantity, and serial number range flags so you know exactly which revision your machine takes. Need a new guide wheel assembly? Look up part 94 07 618 / ENSEMBLE ROUE GUIDE and cross-reference your machine’s serial number. That level of detail saves you from ordering a part that physically won’t fit.

Track Down the Correct Part Number

Page 3 shows the part number entry format used throughout the catalog. Each entry lists the item position, quantity, German description, English translation, serial number breaks, wear indicator codes, and exchange part flags. The catalog uses a five-digit graphic number and a date stamp – you verify the part against your machine’s production date. Compare that to a generic PDF where the only thing you see is a blurry illustration. Here, you get the factory’s own documentation on how to interpret the columns. If a part has a fabrication number like [X2X515N0050], you include that on your order. Miss it, and you’ll get the wrong piece.

ENSEMBLE MOTEUR ET POMPES: Engine and Pump Assembly

This section covers the entire powertrain front end: engine mounting, air intake, exhaust, cooling circuit, combined radiator, expansion tank, and the variable-displacement pumps. Multiple pages group the pump assemblies – for example, POMPE VARIABLE part numbers 10 29 223 7, 10 35 629 8, and 10 47 607 8 each with its own exploded view. The hydraulic motor assemblies (MOTEUR HYDRAULIQUE) and pressure limiters are cross-referenced. You also get the full clutch assembly, pump gear train, and seal kit (POCHETTE DE JOINTS). If you’re rebuilding a pump, you need that seal kit part number from this catalog – aftermarket kits are a gamble.

3 Critical Sections You Cannot Skip

First, the hydraulic installation sections – 94 03 660 and 94 03 661 – which cover the main valve block, control console, pressure filter, return filter, and accumulator. If you’re chasing a drift or a hydraulic leak, those pages give you the exact cartridge valve numbers. Second, the track chain sections: 94 13 686 / CHAINES D6H TUILES 1 NERV. and 10 29 639 6 / CHAINE PRELUBRIFIE. You get the chain pitch and link count from the illustration. Third, the travel mechanism section – MECANISME DE TRANSLATION and its planetary gears. Missing a planetary gear tooth? The part number for ROUE PLANETAIRE (94 44 284 03) is right there. Skip these, and you’ll be flipping pages for hours.

Does This Catalog Cover the Hydraulic Installation?

Yes. The INSTALLATION HYDRAULIQUE chapters run from page entries for block assemblies, distributor valves, pilot control devices, and the entire console. Look up the accumulator (ACCUMULATEUR A MEMBRANE, part 50 03 558) or the pressure filter (FILTRE DE PRESSION, part 58 02 444). Even the little things like drain plugs and oil filler caps are cataloged. The servo motor and electro-regulator for the Litronic system are included. If you’re dealing with a sluggish steering response, the SERVO MOTEUR (10 04 176 9) and the CLAPET DE COMMANDE (10 28 932 7) are the parts you need to verify.

Why Factory Specs Matter More Than Aftermarket Diagrams

Aftermarket parts books for construction equipment are usually scanned from old photocopies with missing revisions. This 2010 Liebherr catalog was printed at a time when the PR 734 L and PR 724 L were current production. The serial number break information on each page tells you exactly which parts superseded which. For example, under ENSEMBLE MOTEUR ET POMPES you’ll see separate listings for engine/pump assembly parts depending on whether your machine is below or above serial number 3094. An aftermarket PDF won’t tell you that – it’ll list one part number and you’ll order it, only to find the bolt pattern doesn’t line up. That costs you time and money.

Is this catalog in English?

The catalog is primarily in French and German, but the part numbers and exploded views are universal.

How do I find the correct part number for my machine?

First, locate the machine’s type and Fahrzeug-Ident Nr. on the serial plate. Then open the catalog and go to the relevant group – for example, ENSEMBLE MOTEUR ET POMPES. Each part entry includes a serial number break column (e.g., “from 3094 – to 3095”). Compare your machine’s serial against that range. The illustration shows the position number, and the table gives the Liebherr part number plus quantity. If a fabrication number like [X2X515N0050] appears, write it down verbatim – the supplier needs it. Cross-check the part description in German and English to confirm it’s the right component. This process sounds detailed, but it’s the only way to guarantee you order the exact part Liebherr installed at the factory.
