Terex ST-50 2009 Parts Catalog – Factory OEM Parts Breakdown

You ordered a hydraulic hose for an ST-50 and got the wrong fitting. That part was supposed to be a quick fix, but now you are down a day waiting for the next shipment. That is exactly when you need the Terex ST-50 2009 Parts Catalog on your bench – not a third-party knockoff with drawings that don’t match the serial number on your machine. This is the original factory book, 28 pages, printed by Terex in 2009 (Part Number 6051-017). It covers every assembly from the cab fascia to the undercarriage, with serial number breaks so you get the correct superceded part. No guesswork, no returns.

Serial Number Breaks – Cab Facia and Chassis (Page 1A)

Every section in this Parts Catalog is keyed to Serial # DFA 00353-Current. That means the exploded views and part numbers apply to machines built from that serial onward. Section 1 covers the Standard Cab Facia Assembly, and Section 3 gives you the Chassis/(R.O.P.S.) Assembly. If you are replacing a windshield or a door seal, the optional assemblies for Roof/Rear Window (Section 20) and Windshield (Section 21) are listed separately – don’t assume a universal part fits. The serial break tells you exactly which revision your machine is.

7 Systems Where You Need the Correct Part Number

This catalog isn’t a service manual – it is a parts locator. But from experience, I can tell you that tracking a leaking pilot line or a blown drive motor seal starts with the right part number. The table of contents includes:
– Standard Cab Facia Assembly
– Cab Interior
– Chassis (R.O.P.S.)
– Radiator/Oil Cooler Assembly
– Hydraulic Reservoir Assembly
– Hydraulic Control Assembly
– Pilot Generation Block
– Hydraulic Drive Assembly
– Hydraulic Auxiliary Assembly (Optional)
– Two-Speed/Brake Manifold
– Auxiliary Manifold (Optional)
– Engine Assembly
– Intake/Exhaust Assemblies
– Battery Assembly
– Fuse Panel Assembly
– Torsion Axle Assembly
– Undercarriage Assembly LH & RH
– Snow Blade Assembly (Optional)
– Roof/Rear Window Assembly (Optional)
– Windshield Assembly (Optional)
– Left and Right Door Assemblies (Optional)
– Personnel Carrier Assembly (Optional)

That covers the whole rubber track loader from bumper to counterweight. Page numbers are noted in the manual – for example, the engine assembly starts on page 12-A.

Fluid Specs and Lubricant Part Numbers – Page 2-3

The front of the catalog includes a table of General Service Items & Lubricants. You get the manufacturer and part number for engine oil filters (Perkins), primary and secondary air filters (Donaldson P609218-016-140 and P602427-016-140), diesel fuel filter (Perkins 26560017), antifreeze/coolant, engine oil (Multi-Grade 10W-30), multi-purpose lithium grease, and wheel lube. These are the actual OEM numbers – not cross-references. Use them when you call your dealer or order online.

Aftermarket vs. OEM – Why This Catalog Wins

I have seen aftermarket parts catalogs that show a generic hydraulic control valve for three different loader models. Then you bolt it on and the port orientation is wrong. This Terex factory document is drawn directly from the CAD data used to build the machine. Every bracket, every seal, every bolt is shown in its exact location. The page for the Hydraulic Control Assembly (Section 6) gives you the breakdown with part numbers that match the serial break. Third-party books skip the serial number details – that is how you waste a week on a return. Stick with the OEM document if you want to get the job done without a second order.

Who Actually Needs This 28-Page Catalog?

You need this if you maintain a fleet of Terex ST-50 loaders, or if you own one and plan to keep it running for another five years. A shop that does warranty work for a Terex dealer will have this on a shelf. Home garage enthusiasts working on compact track loaders should also buy it – one wrong part order can eat up the savings of doing your own repair. The 28 pages cover everything from the engine assembly (Section 12) to the undercarriage (Section 17). For a professional, it means accurate quotes for customers. For a DIY guy, it means not having to measure a broken part against a ruler at the parts counter.

FAQ – Two Common Questions

Does this Parts Catalog include wiring diagrams or torque specs?

No. This is strictly a parts breakdown. It shows exploded views with callouts and part numbers. For torque values or repair procedures you need the corresponding service manual.

How do I find the correct part for my machine if the serial number is before DFA 00353?

This catalog covers serial # DFA 00353-Current. If your machine’s serial is lower, you need the earlier revision. Terex issued updates – check the print date on the cover (05-09). For pre-00353 machines, look for the previous edition. The part numbers may differ for older cabs and undercarriage components.

When you are standing at a bench with a disassembled hydraulic reservoir, the last thing you want is to wonder which O-ring to buy. This Terex ST-50 Parts Catalog gives you the factory drawing and the part number – that is it. Stop searching online forums for a fuzzy scan. Access the Factory Manual from AutoRepairManuals and get the same document Terex technicians used.
