Takeuchi TB1140 Parts Catalog

Nothing burns time like ordering the wrong seal, the wrong hose, or the wrong bearing for a machine that’s sitting dead in the yard. I’ve seen it happen more times than I care to count—guy grabs a part number off a third-party site, bolts it on, and it’s two millimeters off. Now the machine is down another week waiting for the correct piece. That’s where this Takeuchi TB1140 Parts Catalog comes in. It’s the factory-issued book, printed from Takeuchi’s own files. 479 pages of exploded diagrams, part callouts, and the exact numbers you need to ring up the dealer and get the right part the first time.

Engine & Electrical System Parts Reference

The third section of the catalog is marked “ENGINE & ELECTRICAL SYSTEM.” Inside, you’ll find the complete parts breakdown for the Isuzu BB-4BG1-TRE engine that powers the TB1140. Every gasket, injector line, belt, and mounting bracket is drawn with a corresponding part number. Electrical components—alternator, starter, sensors—are all called out. If you’ve ever tried to match a wiring harness connector by eyeball, you know the value of having the factory illustration. You get the part number. You order it. Done.

Does the TB1140 Parts Catalog Include the Isuzu Engine Section?

Yes, it does. There’s a subsection titled “Engine for BB-4BG1-TRE ( ISUZU )” with its own parts index and contents page. That means when the fuel lift pump goes or you need the thermostat housing, you’re not flipping through generic diagrams. You go straight to the Isuzu engine section and pull the exact figure reference. No cross-referencing, no guessing. The catalog also covers the Engine as a whole within the main ENGINE & ELECTRICAL SYSTEM chapter. If you’re working on the TB1140, this is the only parts list you should trust.

9 Sections of Factory Diagrams

The manual is organized into nine clear sections. Starting with UNDERCARRIAGE, then TURNTABLE & CONTROL LEVER, ENGINE & ELECTRICAL SYSTEM, HYDRAULIC PIPNG & TANK (their spelling, not mine), COVER & CAB, HOE ATTACHMENT, DECAL & TOOL, HYDRAULIC DEVICE, and finally a PARTS INDEX. Every section uses the same Takeuchi part numbering system. Once you learn how to read the exploded views—the manual includes instructions on that—you can find any part on the machine fast. The PARTS INDEX at the back lets you look up a part number alphabetically if you already have a number and need to see where it lives.

Undercarriage: Identify Rollers and Sprockets Without Second-Guessing

The undercarriage on a machine this size takes a beating. Track chains, carrier rollers, sprockets, idlers—they all wear and need replacement. Section 1 shows every component with callout numbers. You can match the existing roller diameter or sprocket tooth count to the diagram without pulling a caliper. Just find your serial number range (this catalog covers S/N 51400005- and up) and look up the part. The catalog is serial-number-specific, which is critical for undercarriage components because Takeuchi changed designs over production runs.

OEM vs Aftermarket Parts Catalogs: Why Factory Specs Are Critical

Aftermarket parts catalogs are a gamble. I’ve watched guys order a hydraulic pump seal kit from a knockoff supplier only to find the O-ring grooves are off by 0.5 mm. You lose a day and the cost of the kit. This catalog comes from Takeuchi’s own files—Book No. BN0Z002. The part numbers in here are the same ones the dealer sees on his terminal. If you need to reference the Takeuchi TB1140 Workshop Manual for torque specs or service procedures, that’s a separate document. But for ordering parts, this catalog is the only source I’d trust. Takeuchi TB1140 Workshop Manual – Section: I . General covers safety and basic maintenance, but it doesn’t have the parts breakdown. Get both. While you’re at it, the Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual is available for that compact track loader if you have one in the shop.

The Electrical section inside ENGINE & ELECTRICAL SYSTEM lists every relay, fuse, harness, and connector. If you’re chasing a short and need to order a replacement connector housing, the diagram tells you the exact part. No more cutting up pigtails from a junkyard harness and hoping the pins match. That kind of guesswork causes more problems than it solves. The automotive industry Automotive Industry Overview shows how standardized parts numbering has become, but only the factory catalog gives you the correct supersession history.

Do I need the serial number to use this catalog?

Yes. This catalog is serial-number-specific from S/N 51400005-. Without the serial number you risk ordering parts from the wrong build phase. Write it down before you open the catalog.

How many pages?

479 pages of part diagrams and indexes.

What sections are included?

UNDERCARRIAGE, TURNTABLE & CONTROL LEVER, ENGINE & ELECTRICAL SYSTEM, HYDRAULIC PIPNG & TANK, COVER & CAB, HOE ATTACHMENT, DECAL & TOOL, HYDRAULIC DEVICE, and PARTS INDEX. The Engine subsection covers the Isuzu BB-4BG1-TRE with its own parts list. That’s everything from the track frame to the top cab structure. If it bolts onto the TB1140, it’s in here.

Is this the same as the service manual?

No. This is a parts catalog for ordering components. The workshop manual gives you removal, installation, and torque specs. You need both to work efficiently. The parts catalog does not include repair procedures or bolt torques.

If you’re serious about keeping that TB1140 running without downtime from wrong parts, stop cross-referencing mismatched aftermarket lists. Get the factory document that every Takeuchi dealer uses. Access the Factory Manual now and put the correct part numbers on your next order.
