Terex TW190 2008 Parts Catalog

If you’ve ever ordered a part for a Terex TW190 and ended up with the wrong seal kit, axle housing, or hydraulic pump, you know the pain. That’s time lost, machine down, and money wasted. This isn’t a novel – it’s a 391-page OEM parts catalog printed in 2008 for the TW190 mobile excavator. Page 2 of this book starts with a bold warning: “IMPORTANT: parts without an order number cannot be supplied as spare parts!” And right below that: “When submitting orders, always state the serial number.” That’s not suggestion – that’s instruction. Skip it and you’re guessing. Guessing costs you hours and your customer’s patience.

Underwagen (Chassis) – Identifying the Carrier Group

Section 1 of this catalog covers the Unterwagen Mobil – the undercarriage and carrier frame. Every bolt, bracket, and bushing is listed with its order number and position on the diagram. You want the steering axle? The definition of left and right is clearly laid out: “Spare parts for the left-hand ‘L’ or right-hand ‘R’ side of the excavator are to be seen from the cabin facing the direction of forward travel.” That’s on page 2 as well. If you need a rear window, the order number is 6086638 – but only if your serial number falls within the covered range. No serial number? No part. That’s how OEM documentation works.

Axles (Achsen) and Steering Axle Orientation

Section 2: Achsen – axles. This isn’t a generic axle diagram. It’s specific to the TW190, with part numbers for bearings, seals, and axle housings. The catalog includes the symbols D (Dichtsatz/seal set), V (Verschleißteil/wear part), and R (Reparaturatz/repair kit). You order a repair kit without checking the “R” symbol? You’ll get a seal set instead. That’s a $400 mistake. The OEM catalog labels each part with its symbol, so you know exactly what you’re buying.

Hydraulic Components – Pumps, Motors, and Valves

Sections 5 through 8 drill down into the hydraulic system: Hydr.Pumpen u.Motore, Hydraulik-Anlagen, Hydr.Komponenten, and Steuerventile. These are the heart of any mobile excavator. The catalog gives you exploded views of the pump group, control valves, and cylinder components. Need a seal kit for the main control valve? Look for the “D” symbol next to the valve section. The part number is right there, cross-referenced to the serial number range. No guesswork.

Electrical System (Elektro-Anlagen) – Wiring and Lighting

Section 12 covers the Elektro-Anlagen – the entire electrical system, including Rundumleuchte (rotating beacon) and Arbeitsscheinwerfer (work lights). For a 2008 TW190, these are specific to the year and serial number. You’ll find part numbers for the harness connectors, lamp assemblies, and switches. Don’t trust an aftermarket diagram that lumps all TW190 years together. This catalog matches the exact wiring configuration for your serial number range: starting at 190 W 301265 as listed on page 1.

Why OEM Parts Catalog Beats Aftermarket Diagrams

Aftermarket parts catalogs often photocopy old editions, leave out revisions, or mislabel part numbers. This is the real thing – Terex factory documentation from 2008, 391 pages, in German, English, and French. The OCR excerpt even includes a disclaimer: “As we are engaged in a constant process of improving our machinery, it is possible that your excavator will incorporate innovations which do not taken into consideration when this parts list was prepared.” That’s transparency you won’t get from a third-party PDF. You get the most current version available for that production run.

3 Reasons You Need This Catalog Before Touching the TW190

First, you need the serial number cross-reference. Page 2 shows the part number 6086638 for a rear window – but only for chassis 190 W 301265 and above. Second, the ordering example teaches you how to read the catalog: figure number, position number, order number. Third, the symbols (D, V, R, M, NB) prevent you from buying the wrong grade of part. Wear parts (V) have a different lifecycle than seal sets (D). Order a repair kit when you need a seal set and you’ll have leftover gaskets you can’t use.

Frequently Asked Questions

Does this catalog include engine parts?

Yes. Section 10 covers Oel u.Kraftstoff,Ben – engine oil and fuel systems. It lists oil filters, fuel filters, injectors, and related components with order numbers.

How do I determine the correct axle assembly for my TW190?

Go to Section 2 (Achsen). Find your serial number range in the heading. The diagram will show the axle as either left or right. Use the steering axle orientation rule from page 2: left/right is defined from the cabin looking forward. Then match the part number to your chassis number.

Can I use this catalog for a different Terex model?

No. This is specific to the TW190 mobile excavator from 2008. Part numbers and diagrams differ between models.

What do the symbols D, V, R, M, and NB mean?

D = seal set, V = wear part, R = repair kit, M = sold by the meter, NB = as needed. These are listed on page 2 of the catalog.
