Terex TW140 2007 Parts Catalog – OEM Factory Manual

You’ve got a Terex TW140 mobile excavator in the bay, the customer needs a steering axle seal kit, and you pull up a third-party parts list. Thirty minutes later you’ve ordered the wrong part because the aftermarket drawing didn’t match your machine’s serial number range. That’s time and money down the drain. This Terex TW140 2007 Parts Catalog is the factory-issued 259-page document that eliminates that guesswork entirely. It was printed by Terex in May 2007, order number 6103505, and covers machines starting from serial number 140 W 301265.

Serial Number: The First Step Before Ordering

Page 2 of this catalog spells it out in bold: “Bei Bestellung unbedingt Fabr.-Nr. angeben.” Translation: when ordering, always state the serial number. The manual points you to figure 050.100.50.10.1505, position 6, to locate the data plate. One part – rear window, 6066536 – is shown as an example. If you skip this step you’ll likely order a part that doesn’t fit. I’ve seen guys pull a steering cylinder seal kit off a shelf because the illustration looked right, then find out the TW140 changed axle designs at serial 140 W 305000. This catalog tells you exactly which parts apply to your machine.

Parts Breakdown: Figure Numbers and Exploded Views

The catalog uses figure numbers (e.g., 050.100.50.10.1505) to organize exploded diagrams. Each figure shows a subsystem – steering axle, engine, swing gear – with numbered callouts. Below the figure is a parts table listing order number, description, quantity, and notes. No vague references. If you need the seal set for the steering axle, you pull the right figure, find the callout, and get the factory order number. This is OEM documentation, not a reprint from some third party that omitted half the tabs. For comparison, check out Schaeff-terex SKL 863 2003 Parts Catalog – OEM Factory Manual if you work on that platform.

Symbols: D, V, R, M, NB – What They Mean

Page 2 defines the symbols used throughout: D = set of seals / sealing component; V = part subject to wear; R = repair kit; M = supplied by the metre (state length); NB = as required. When you see a callout marked “V” you know that bushing is a wear item and should be checked every 500 hours. A “D” means the seal must be replaced as a whole set – don’t piecemeal it. This catalog cuts through the fog. No need to guess whether a part comes as a kit or individual piece.

Left-Hand vs Right-Hand Orientation

The manual includes a clear definition of left and right sides as seen from the cab facing forward travel. Steering axle must be in traveling position. This matters for hydraulic cylinder mounts, boom hose routing, and anything that’s side-specific. Aftermarket catalogs often omit this orientation, leading to swapped parts and a second order. This OEM catalog gives you the factory standard.

Why OEM Parts Catalogs Beat Aftermarket Lists

I’ve had it with photocopied binders that lose detail or use generic part numbers. This 259-page catalog is a scan of the original Terex publication. Every figure, every order number, every footnote is factory accurate. The back page reminds you that parts without an order number cannot be supplied – so you know the list is complete. Aftermarket reprints sometimes drop the “V” and “D” notations, leaving you guessing about wear limits. Not here.

FAQ

Does this parts catalog include torque specs or repair procedures?

No. This is a parts catalog, not a service manual. It focuses on ordering correct replacement parts – figure numbers, part numbers, quantities, and symbols. For torque specs and overhaul steps you need the corresponding service manual.

How do I know which parts apply to my TW140 serial number?

Match your serial number against the start range given (140 W 301265 and up). Then look up the subsystem figure and check the parts table – some parts list a serial number break in the notes column.

Will this catalog work for a TW140 built after 2007?

Not reliably. Terex may have updated components after this edition. Always verify with a later parts catalog if your machine is newer than 2007.

What if a part has no order number listed?

Page 2 states: “Teile ohne Order No. sind als Ersatzteil nicht lieferbar” – parts without an order number cannot be supplied. That means the part is not available individually; you may need to order a subassembly.
