Every part on your Takeuchi TB260 mini excavator carries a factory number, and this 523-page parts catalog PDF (OEM #BQ0Z001-2) shows you where to find it. Exploded views with numbered callouts run the whole machine: undercarriage (track rollers, front idler, crawler belt), slewing device and turntable, the Yanmar 4TNV84T engine, hydraulic piping and tanks, cover and cab, boom, arm and bucket, down to the swivel joint, control valve, travel and slew motors, decals and tools. Match a callout to its part number and quantity before you call the dealer, so the seal kit or track roller you order is the right one the first time. Ordering the wrong part twice hurts more than the breakdown did. Bookmarked and text-indexed: type a part name, jump to the diagram, place your order.

Takeuchi TB260 Common Problems This Manual Covers
Takeuchi TB260 fuel filter and water separator part numbers unclear when ordering the 1000 hour service kit
Open the fuel tank and fuel piping breakdowns on page 250; the exploded views separate the fuel filter, water separator element, and supply pump connector hardware. Record the machine serial number from the frame plate first, then match it to the serial range printed beside each part number before ordering the filter set.
Manual Section: Fuel Tank & Fuel Piping p. 250Hydraulic hoses leaking at the fittings, can't match replacement hose part numbers to the circuit
Measure the removed hose end to end in millimeters and note both fitting thread sizes. Trace the line back to its circuit in the hydraulic piping diagrams beginning on page 185, then match your measurements against the hose callouts in the parts list. Order fresh O-rings for every fitting you crack open.
Manual Section: Hydraulic Piping & Tank p. 185Air cleaner outer and inner elements look different from aftermarket listings, unsure which one fits
Remove both elements and compare them against the air cleaner exploded view on page 76; the outer and inner elements carry separate part numbers and do not interchange. Verify element length and outer diameter in millimeters against the old parts, and confirm your serial number falls inside the listed range before buying aftermarket substitutes.
Manual Section: Engine & Accessories p. 76Boom cylinder weeping oil at the rod, seal kit part number not stamped on the cylinder
Pull up the boom and attachment parts diagram on page 331. Seal kits list as a single numbered item under each cylinder, so order the kit rather than chasing individual seals. Measure the rod diameter in millimeters and compare it to the parts list callout to confirm which cylinder you have before ordering pins or seals.
Manual Section: Hoe Attachment p. 331Hydraulic pump growling under load, need pump assembly and coupling part numbers to price the job
Work from the hydraulic device section on page 231 for the pump, coupling, and mounting hardware breakdowns; the pump lists as a complete assembly with the coupling element called out separately. Verify your serial number against the range shown beside the assembly number, then quote both the pump assembly and the coupling together.
