Takeuchi TB175 Parts Catalog – 716 Pages of OEM Factory Specs

I have lost count of how many times I have watched a job stall because somebody ordered the wrong seal, the wrong bearing, or the wrong hydraulic line. Nine times out of ten, they were using a third-party parts list that had a misprint or a cross-reference that didn’t exist. That is exactly why a real Takeuchi TB175 Parts Catalog needs to be open on your bench before you write up a single order. This is not a reprint from a discounter. This is the factory document, 716 pages thick, with every exploded view, every part number, and every compatibility note that Takeuchi issued for the TB175 series.

8 Chapters Covering Every System

The manual breaks down the machine into eight major sections, and you can jump directly to what you need. Chapter 1 is the undercarriage – track frames, rollers, sprockets, idlers. Chapter 2 covers the turntable and control lever assembly. Chapter 3 is the engine and electrical system, which includes separate subsections for both the 4TNE98-TBZ and 4TNV98-VTBZ engine variants. Chapter 4 deals with hydraulic piping and the tank. Chapter 5 gets into the cover and cab components. Chapter 6 is the hoe attachment. Chapter 7 covers decals and special tools. Chapter 8 lists hydraulic device components. Each chapter ends with its own parts index, so you are never flipping blind.

What Makes This Parts Catalog Different from Aftermarket?

Most aftermarket catalogs I have seen do not show the inter-changeability notes that Takeuchi stamps into the original manual. Look at the “How to read the parts manual” section starting on page 2 of the PDF. It explains the star marks, the asterisks, and the letter codes that tell you whether a part supersedes an older design or whether it has been discontinued and replaced. An aftermarket list will just show a part number and hope you guess right. This manual tells you, for example, if a bolt has been changed from a plain hex to a flanged head, and whether the two are interchangeable. That kind of detail keeps you from ordering parts that do not fit.

Engine & Electrical System Coverage

If you are rebuilding the power plant on your TB175, you need the engine-specific subsections. The manual includes a dedicated “Engine for 4TNE98-TBZ” section and a separate “Engine for 4TNV98-VTBZ” section. Each one has its own contents page and parts index. The electrical system is grouped in Chapter 3 as well – alternator, starter, wiring harness, sensors. You get the factory part numbers for every connector and relay. I have used these pages to track down a crank-no-start condition on a TB175 that had a corroded engine harness connector; the part number from the manual matched exactly, and the machine was back in the dirt the same day.

Read the Manual Before You Order Parts

Take the time to read the “How to use the parts manual” instructions on page 5 of the PDF. It walks you through the machine orientation – right and left as seen from the operator seat in the forward operating position. It also explains the ordering procedure: machine model, serial number, part number, part name, quantity. If you skip that step and guess the serial number range, you might order a part that was only used on earlier machines. The manual specifies that serial numbers from 17510003- are covered, so check your machine’s plate before you order.

Undercarriage and Hydraulic Components: Exploded Views

Chapters 1 and 4 are where most of the heavy lifting happens. The undercarriage section shows every roller, track shoe, and sprocket with a keyed diagram. The hydraulic piping and tank section gives you the routing of every hose, the fittings, and the tank itself. This is the same drawing that the Takeuchi dealer uses to pull parts. If you are replacing a swing motor or a travel motor, the hydraulic device chapter (Chapter 8) has the exploded view for that assembly. No guesswork, no aftermarket photocopy – just the factory image.

Does this catalog cover all serial numbers for the TB175?

Yes. It covers TB175 serial numbers from 17510003- onward. Always verify your machine’s serial number before ordering.

Are torque specs or repair procedures included in this parts catalog?

No. This is a parts catalog – it provides exploded views, part numbers, and interchangeability information. For torque values, overhaul procedures, and diagnostic steps, you need the Takeuchi TB175 Workshop Manual or Service Manual. The parts catalog is meant to be used alongside those documents, not in place of them.

Can I use this catalog to rebuild the engine?

Absolutely. The catalog contains dedicated sections for both the 4TNE98-TBZ and 4TNV98-VTBZ engines, with complete exploded diagrams of the cylinder head, block, fuel system, and cooling system. You will get the correct piston ring set, gasket kit, and seal part numbers.

Is the manual entirely in English?

It is bilingual: English and Japanese. The parts lists, diagrams, and instructions for ordering are printed in English. Some reference notes appear in Japanese, but the essential information for parts identification is clear in both languages.
