When a control valve or travel motor on your TB135 needs a replacement spool or seal kit, this Takeuchi TB135 parts manual PDF (OEM ID BG4Z010, 659 pages) breaks the whole hydraulic excavator down into exploded views with factory part numbers, from the hydraulic device group to the undercarriage. Every assembly appears as a numbered exploded drawing keyed to a parts list, so you can identify a front idler, track adjuster, swing bearing, or boom cylinder component and read its exact part number instead of guessing from a photo. Coverage runs through three engine variants too, the 3TNE88 and both 3TNV88 builds, each with its own cylinder block, gear housing, and manifold breakdowns. Order the wrong bushing once and the machine sits while the right one ships. This parts catalog is a bookmarked, text-searchable PDF; buy it once and it stays with your TB135 for good.

Takeuchi TB135 Common Problems This Manual Covers
Takeuchi TB135 keeps throwing tracks, need part numbers for front idler, track rollers, and sprocket
Check the chassis parts diagram on page 4 and match each roller, idler, and sprocket to the parts number list on page 5. Measure remaining sprocket tooth height with calipers; if the undercarriage shows around 50 percent wear and tracks still drop, order the front idler and track adjuster together.
Manual Section: Undercarriage p. 4Which travel motor assembly fits my serial number, machine bogs down and stalls while tracking
The travel motor is broken out on pages 500-511 of the Hydraulic Device section, and the book splits it by serial number: pages 500-505 cover S/N 13510004-13516744 and pages 506-511 cover S/N 13516745-. Each range is drawn in three parts - reduction section, motor section and valve section - so check your machine's serial plate first, then take the reduction gear, motor and seal-kit callouts from the matching range only.
Manual Section: Hydraulic Device p. 500Three engine variants listed, not sure which cylinder head parts list matches my engine
Check the engine data plate and match the stamped model to the right section: 3TNE88 parts begin on page 526, 3TNV88-QTB and QTB1 on page 580, and 3TNV88-QTB2 on page 624. Measure your old head gasket bore in millimeters as a sanity check, then pull part numbers only from your engine's exploded view.
Manual Section: Engine 3TNE88-(E)TB(1) p. 526Bucket pins and bushings worn out, need correct part numbers and pin sizes for replacement
Check the boom and attachment parts diagram on page 322. Match each pin and bushing callout to the Hoe Attachment parts list, noting that boom, arm, and bucket pins carry different part numbers. Measure your old pin's diameter and length in millimeters with calipers, then confirm those dimensions against the listed part before ordering.
Manual Section: Hoe Attachment p. 322Need seal kit part numbers for pilot valve and control valve, levers feel sloppy and leak oil
The valve breakdowns sit early in the Hydraulic Device section: the control valve is on pages 432-433, the remote control valve on pages 468-469, and the pilot valve on pages 456-459, where the book splits it by serial number - pages 456-457 for S/N 13510004-13514050 and pages 458-459 for S/N 13514051-. Write down every seal and O-ring callout for the valve you are resealing from the range that matches your serial plate, and measure any unreadable O-ring's inside diameter in millimetres before ordering.
Manual Section: Hydraulic Device p. 432Frequently Asked Questions
What are the replacement specifications for track rollers on a Takeuchi TB135 excavator?
The track roller assembly (steel) is part number 0431311100, and the track roller assembly (rubber) is part number X04313-11000-2. There are 8 roller sub-assemblies required for the machine. p. 15
What are the replacement specifications for the front idler on a Takeuchi TB135?
The front idler assembly depends on the serial number. For serial numbers 13510004 to 13512646, use part number 0431410000. For serial numbers 13512647 and above, use part number 0371400000. p. 17
What is the cylinder head bolt torque specification for the Takeuchi TB135's Yanmar 3TNE88 engine?
The cylinder head studs are listed on page 527, in the 3TNE88 engine's CYLINDER BLOCK parts list: reference 27, part number Y129150-01200, quantity 14. The same stud appears again on page 581 for the 3TNV88-QTB/QTB1 engine and on page 625 for the 3TNV88-QTB2. The tightening torque itself is not printed in this parts catalog — it lists parts, not specifications, so take the torque value from the Yanmar engine service manual. p. 527
What is the part number for the air cleaner element for the 3TNE88 engine?
The air cleaner element for the 3TNE88 engine is part number Y12961212690. p. 99
Where does this manual list the fuel filter part number for a Takeuchi TB135?
The fuel filter is listed on page 427 as part number 1990197054 (Yanmar cross-reference Y129907-55800), together with the return filter 1551103300 and the engine oil filter 1990197055. Note where it sits: this entry is in the TOOL & ACCESSORIES (2/2) (for China) list, not in the engine sections — the 3TNE88, 3TNV88-QTB/QTB1 and 3TNV88-QTB2 parts lists in this catalog do not carry a fuel filter line of their own, so check the number against your machine before ordering. p. 427
