Every bolt, hose, and roller on your machine lives somewhere in this 429-page Takeuchi TL140 Parts Manual PDF (OEM #BT9Z009), the factory parts catalog for the TL140 Compact Track Loader. Exploded views carry factory part numbers for the whole machine: undercarriage (track rollers, front idler, track adjuster, travel device), main frame, engine and electrical, hydraulic piping and tank, cover and cab, attachment, decals and tools, plus the full hydraulic device group from control valve to travel motor and hydraulic pump. Serial-number breaks are called out, so a valve for 21400011-21405078 never gets confused with the 21405079-and-up version; Gehl and Mustang builds get their own breakdowns too. Order the 65A fusible link or the 14V, 1.4W bulb by exact number, not the parts counter's best guess. Wrong part means another week of downtime. Bookmarked with a full index; search any part number and jump straight to the page.

Takeuchi TL140 Common Problems This Manual Covers
Takeuchi TL140 track roller and front idler part numbers unclear, tracks worn and adjuster losing tension
Open the chassis parts diagram on page 16 and match each callout number to the parts number list on page 17. Track Roller A and Track Roller B carry different part numbers, so count rollers per side before ordering. Verify whether your serial falls in the 21400011-21401390 travel device range or 21402001 and up before buying the adjuster.
Manual Section: Undercarriage p. 16Lever lock relay and safety bar switch relay look identical, can't tell which part number to order
Trace each relay on the wiring diagram and note its circuit position before pulling a part number. Verify the fusible link feeding the lock circuit is rated 65A and the branch fuses at 10A, 20A, or 30A per page 105. Match connector pin count to the parts list callout so you don't grab the stop solenoid relay by mistake.
Manual Section: Engine & Electrical SystemFront work light burned out, unsure which bulb rating fits the housing
The work light bulb spec sits on page 115: the work light takes a 12V, 55W bulb. Do not confuse it with the 14V, 1.4W indicator bulb listed on page 91; the bases are different. Pull the lamp housing part number from the electrical parts list and order the lens gasket at the same time if it shows cracking.
Manual Section: Engine & Electrical System p. 115Hydraulic line filter and suction strainer part numbers vary by serial number, oil running noisy and dark
Work through the hydraulic parts diagram on page 124, then find your machine in the valve and accessories breakdowns: serial range 21400011-21405078 lists different part numbers than 21405079 and up, and high flow machines from 21403459 carry their own listing. Order the line filter, spin-on element, and suction strainer together; contaminated oil means replacing all three at once.
Manual Section: Hydraulic Pipng & Tank p. 124Need compressor and condenser part numbers for the cab air conditioner, system blows warm air
Check the air conditioner exploded views for the compressor, condenser, and unit assembly, then confirm the refrigerant charge listed as 100g of gas on page 273 and write it on the work order before ordering parts. Match hose routing and fittings against the cab and interior parts diagram to catch any superseded line part numbers.
