Takeuchi TB175W Parts Catalog – 835 Pages of Factory Part Numbers

If you are turning wrenches on a Takeuchi TB175W, you have felt the pain of bolting on the wrong part because your reference was a third-party drawing. That stops here. This Takeuchi TB175W Parts Catalog is the exact binder the factory assembly line uses – 835 pages, serial number 17520003 and up. I have spent twenty-eight years hunting down part numbers across dealer systems, and nothing beats having the OEM breakdown in your hand when a customer is waiting on a crown wheel or a travel lever assembly.

Look at the index: 1 UNDERCARRIAGE, 2 TURNTABLE & CONTROL LEVER, 3 ENGINE & ELECTRICAL SYSTEM, 4 HYDRAULIC PIPNG & TANK, 5 COVER & CAB, 6 HOE ATTACHMENT, 7 DECAL & TOOL, 8 HYDRAULIC DEVICE, plus a NUMERICAL INDEX. That is eight major sections covering every wearable part on this machine. The undercarriage section alone will save you the headache of mis-ordering track adjusters or final drive seals because the illustration shows you the exact stack-up with part numbers. I have seen a shop order three different pivot metals before getting the right one – this manual kills that guesswork dead.

UNDERCARRIAGE and TURNTABLE – Where the Machine Meets Dirt

Chapter 1 (UNDERCARRIAGE) includes all track frames, idlers, sprockets, rollers, and the travel motor components. Chapter 2 (TURNTABLE & CONTROL LEVER) covers the swing pedestal, travel levers, and pedal assemblies. The OCR excerpt shows the TRAVELLING LEVER & SWING PEDAL breakdown with part numbers like TB17-2800 for the pedal and TB17-2802 for the pivot. You need the correct bolt grade for those pivots – this manual lists every bolt with its spec, not a generic “use grade 8” guess. When you are rebuilding the swing drive, having the factory parts index for the turntable means you can order the exact seal kit without pulling the unit twice.

ENGINE & ELECTRICAL SYSTEM – Two Engine Variants Covered

The Takeuchi TB175W came with either a 4TNE98-TBW or a 4TNV98-XTBW diesel. This Parts Catalog dedicates a full sub-section to each engine. The 4TNE98 section has its own CONTENTS and PARTS INDEX, same for the 4TNV98. That means you get separate part numbers for injectors, cylinder heads, gasket sets, and all Engine components. The Electrical system lives inside Chapter 3 – alternator, starter, wiring harness connectors, sensors. I have seen more downtime from ordering a starter with the wrong nose cone than from actual engine failure. The factory numbering system eliminates that risk. Page 2 of the manual explains how to read the part number structure – a 90030-08040 plate is not the same as a 90030-08055 cover, even though they look identical in the bin. That level of detail is why this is not a reprint from some scanned copy; it is the official OEM release.

Why You Need the OEM Parts Catalog Instead of Aftermarket

Aftermarket parts sites love to show a generic drawing that fits eight machines. The Takeuchi TB175W is not a Toyota Corolla – it has specific part numbers that change by serial number break. This manual tells you the exact part number for every nut, washer, and hydraulic hose. The NUMERICAL INDEX lets you cross-reference a number from the exploded view directly to the ordering page. If you are a DIYer rebuilding a hoe attachment (Chapter 6), you will need the pin and bushing dimensions – aftermarket catalogs often guess those. Factory documents do not guess. They give you the part number and the corresponding noun in five languages. You can take that number to any dealer and get the right box the first time. I recommend keeping a printed copy near the parts washer – dog-earing pages 200 through 250 for undercarriage parts will save you hours of searching.

How to Read This Manual – Serial Number and Part Number System

The manual includes a two-page guide (pages 2-3) titled “How to read the parts manual.” It explains the RESEARCH SYSTEM, the layout of part numbers, and the noun columns in Japanese, English, French, German, Spanish, and Chinese. When you open to any assembly, you see a left column with the reference number, then the part number, then the noun in various languages. The TB175W Book No. BW2Z004 applies to machines from Serial No. 17520003 onward. If you have an older machine, you need to verify through the dealer – this manual covers that range. The HYDRAULIC PIPNG & TANK section (Chapter 4) uses this same format, so you can order a hose assembly by finding the fitting illustration and pulling the number. No need to measure the hose at the machine.

Related Manuals for the TB175W

If you need actual repair procedures – disassembly, torque specs, clearance checks – pair this parts catalog with the service manual. I suggest the Takeuchi TB175W Workshop Manual for that. For a complete parts reference, this Takeuchi TB175W Parts Catalog is the one you are looking at. If you run a TL26 compact track loader alongside the TB175W, the Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual covers that machine with the same factory accuracy. For background on the automotive and heavy equipment industry, you can read the Automotive Industry Overview or the Automotive Industry Overview for context on how OEM documentation standards evolved.

Frequently Asked Questions

Does this manual include torque values for assembly?

No. This is a parts catalog – it lists part numbers, quantities, and illustrations. Torque specs and repair steps are in the Workshop Manual. You need both if you are rebuilding.

Can I order parts directly from the part numbers in this PDF?

Yes. The numbers are factory-issued and current for serial numbers covered. Take the number to any Takeuchi dealer or online parts counter. The manual includes a numerical index that allows reverse look-up from an illustration to the ordering page. I have used this method for years – it works as long as the serial number falls within the range (17520003-).

What kind of hydraulic device information is in Chapter 8?

Chapter 8 (HYDRAULIC DEVICE) covers the main control valve, relief valves, swing motor, and travel motor internal parts – the breakdowns for seals, springs, spools, and housings. These are not repair instructions, but exploded views with part numbers for every O-ring and bushing. If you are resealing a spool, you need this to order the correct seal kit. Without it, you will likely end up with a mis-matched kit that leaks after one shift.

Is this a PDF format or a print book?

Digital access – 835 pages in a searchable PDF. You can print specific pages for the workbench. The file is the original OEM print from Takeuchi, Book No. BW2Z004. No watermarks, no re-sampled scans. Page quality is high enough to read part numbers on a phone screen in the field.
