Terex TW150 2007 Parts Catalog – OEM Factory Manual

I’ve been turning wrenches for 28 years, and nothing burns my time like ordering the wrong part. You get a box, it doesn’t match the old part, and you’re stuck waiting another week. The Terex TW150 is a solid mobile excavator, but if you’re ordering parts without the factory Terex TW150 2007 Parts Catalog, you’re guessing. This 255-page OEM document gives you the exact part numbers, ordering codes, and serial number ranges from the factory. No aftermarket reprints. No translated screw-ups. This is the same book the dealer uses.

Parts Ordering by Serial Number: The Only Way to Get the Right Fit

Page 1 of the catalog makes it clear: every order must include the serial number. The manual gives a sample – for a rear window, Order No. 6066536, but only for Terex TW150 with serial number 150W301265 or later. If your machine is earlier, you get a different part. I’ve seen guys skip this step and end up with a swing gear that didn’t mesh. The factory won’t take it back if you ordered from the wrong range. This catalog prints that range on every assembly. Don’t bypass it.

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

Look at the bottom of page 2. The catalog uses five symbols: D = set of seals or sealing component; V = wear part (bushings, cutting edges, etc.); R = repair kit; M = sold by the meter (hose, wire); NB = available as needed, not a stock item. Ignore these and you might order a single seal when you need the whole kit. That mistake costs time and shipping. The symbols are printed next to each part description. Use them.

Machines that run long hours eat wear parts (V) quickly. The repair kits (R) are smart – they bundle everything you need for a hydraulic cylinder rebuild in one order number. No second guessing which O-ring fits.

Left and Right Side Determination for TW150 Parts

The catalog defines left and right from the cab seat, facing forward travel direction (page 2). L = left side, R = right side. The steering axle must be in front when you check. If you’re standing in front of the machine looking at the boom, that’s the wrong orientation. I’ve had techs order a left-hand track motor when they needed right because they flipped the perspective. This section saves that headache.

Terex TW150 2007 Parts Catalog – 255 Pages of Factory Data

This is not a condensed aftermarket list. 255 pages cover the entire machine: engine, transmission, steering axle (Lenkachse), swing gear, undercarriage, cab, electrical system, and hydraulics. Each section shows exploded diagrams with callouts tied to the order numbers. If you need to identify a seal for the final drive, you find it here. The table of contents is organized by assembly group, not by part name – you have to know where the part lives on the machine. That’s how a factory catalog works. If you’re used to search-by-keyword digital aftermarket lists, this feels different. But it’s accurate. Period.

Why OEM Factory Documentation Beats Aftermarket Copies

Aftermarket part catalogs often omit the serial number ranges and use generic part numbers that don’t cross-reference to the original order numbers. I’ve seen a “universal” O-ring kit that listed the wrong durometer for a TW150 hydraulic pump. With this OEM catalog, you get the exact factory number. The manual even warns: parts without an order number cannot be supplied as spare parts. That means aftermarket lists that skip the order number are useless for ordering from Terex. If you need a part that’s only available from the factory, you need this book.

Frequently Asked Questions

Does this catalog include part numbers for the engine?

Yes, the engine section covers all powertrain components. But you must reference your serial number.

How do I know if a part is obsolete or superseded?

The catalog includes only the original part numbers from the 2007 production period. Parts may have been superseded by newer versions after that date. The factory updates are published in service bulletins. To determine if a part is still current, cross-reference the order number with your local Terex dealer. They can check their system for any supersessions. This catalog gives you the starting point – the original factory number. Without it, you have no baseline. That’s why having the OEM document is critical. If you try to use an aftermarket list, you might get an obsolete number and end up with a part that’s no longer made.

Can I use this catalog to order parts for a machine with serial number outside the range?

No. The catalog covers from serial number 150W301265 onward. Earlier machines may have different part numbers.

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

D means seal set or sealing component. V is a wear part – like bushings or cutting edges. R is a repair kit, typically includes multiple seals and gaskets. M means sold by the meter – usually hose or wiring. NB means available as needed – not a stock item. Those symbols are at the end of each part description. Use them to identify what you’re ordering. Ignoring the symbol can lead to ordering a single seal when you need the whole kit. Always check the symbol before adding to cart.
