Swapping a track roller, front idler or travel motor on a TB15 or TB120 compact excavator starts with the right number, and this 282-page Takeuchi TB15 parts catalog PDF lays out both machines assembly by assembly. Exploded views run from the lower frame, crawler belt and track spring up through slewing device, turntable, operation levers, engine accessories, control box and electrical groups, each with its parts list. The hydraulic device section breaks out the swivel joint, control valves, C.B. and selector valves, boom, arm, bucket, blade and swing cylinders, travel and slew motors and hydraulic pump; the cab, canopy, heater and hoe piping get their own breakdowns. Confirm the collar size before you order: the blade cylinder collar is listed at t=1.6mm, the turntable bushing collar at 3.2mm. If your blade cylinder needs a new collar, quote part 00030-00067. Bookmarked by section and text-searchable, the PDF goes on a laptop or tablet to wherever the excavator is parked.

Takeuchi TB15, TB120 Common Problems This Manual Covers
Takeuchi TB15 swivel joint seal kit part number unclear, canopy and cabin listings show different kits
Check whether the machine is a canopy or cabin unit before ordering. Canopy machines use swivel joint assy 19040-05200 with seal kit 19040-05799 on page 135. Cabin machines use joint assy 19040-06200 with seal kit 19040-06299 on page 136. Verify the dust seal 19040-01695 and the O-ring quantities against the exploded view before you place the order.
Manual Section: Hydraulic Device p. 135Control valve assembly number changes by serial range, unsure which overload relief valve count applies
Read the serial plate first, then open the TB15 Control Valve 1 list on page 138. Serial 00543 to 03635 takes control valve assy 19010-21800 with two overload relief valves 19010-21322. Serial 03636 and later takes 19010-27500 with three. Confirm the main relief valve 19010-21321 and the O-ring quantities for your range on that same list.
Manual Section: Hydraulic Device p. 138Control valve 2 spool oil seal and seal holder quantities unclear when ordering a full set
Check the exploded view for TB15 Control Valve 2 on page 140. Oil seal 14329-00036 and seal holder 19010-09841 are each listed at a quantity of 18, along with spring holder 19010-04151 and spring 19010-21356. The TB120 uses its own Control Valve 2 list on page 141, so order from the page that matches your model plate.
Manual Section: Hydraulic Device p. 140Travel motor and reduction unit seal kits hard to tell apart, floating seal part number needed
Check the Travel Motor exploded view on page 168 and confirm your machine matches the version without parking brake. Motor assy 19031-04400 takes seal kit 19031-04499, which includes oil seal 19031-04404. The reduction unit 19120-02900 has its own seal kit 19120-02999, containing two floating seals 19120-02902. Bearing 19120-02903 is listed separately as item 6.
Manual Section: Hydraulic Device p. 168Cabin window washer and wiper motor part numbers change mid production, wrong part arrives
Check the serial number against Electrical 2 on page 64 for the TB15 cabin. Window washer 17119-10030 fits serial 00543 to 06394, and 17119-10100 fits 06395 and later. Wiper motor 17040-38012 covers serial 01186 to 01421, and 17040-42012 covers 01422 onward. Match the wiper arm the same way: 17041-11550 or 17041-11500.
Manual Section: Upper Machinery 2 p. 64Turntable bushing collar thickness unknown when ordering replacement collars for the upper structure
Check the Upper Machinery 1 parts list on page 33. The turntable bushing collar is listed as part 00030-30003 with a thickness of t=3.2mm, quantity as required (AR). Measure the old collar against 3.2mm so the stack goes back the way it came, and order enough collars to match what you pull out.
