Part of the Kubota Parts Manuals.
One mini excavator, one job across 299 pages: pin down the right part number before another dealer callback eats your afternoon. The catalog maps 146 numbered assemblies through exploded views. Engine work fills 48 pages, from crankcase and piston crankshaft to the injection pump and camshaft components. Hydraulics take another 60, covering the gear pump, hydraulic pump, each control valve spool section, and the full oil piping runs for boom, arm, bucket, and blade circuits. Smaller sub-assemblies get the same treatment: swivel bearing, bucket link, cabin wiper motor, and nozzle holder each carry their own diagram with individual part numbers called out. Cross-shopping the wrong SKU stops here. Everything is bookmarked by system, so you can search an assembly name and jump straight to its diagram.

Kubota KX101 Common Problems This Manual Covers
Kubota KX101 boom cylinder leaking at the rod seal, complete seal kit part numbers needed
Open the Boom Cylinder Component Parts diagram at page 215; it runs through page 216. Every numbered position in the exploded view ties to a line in the parts list beside it. Work through each O-ring, wiper seal, and piston seal by position number, then collect the matching part numbers for a full seal kit order.
Manual Section: 0105 Boom Cylinder Component Parts p. 215Arm and bucket linkage worn, excessive play at pivot joints, pin and bush part numbers unclear
Begin with the Arm section on page 231 and Bucket Link on page 233; the two cover the linkage pin and bush arrangement from page 231 to 234. Both exploded views label every pin, bush, and retaining fastener by item number. Combine the part numbers from each to assemble a full replacement set for the arm and bucket pivot points.
Manual Section: 0113 Arm p. 231Track slipping off or running loose, idler and track roller part numbers not identified in catalog
Pull together three undercarriage sections: Idler on page 241, Truck Roller on page 243, and Crawler on page 245, running from page 241 through 246. Each exploded view lists its wear components and hardware by part number. Confirm the serial number range noted in every parts list before you order, since undercarriage numbers can shift between production batches.
Manual Section: 0118 Idler p. 241Hydraulic oil running hot, need part numbers for oil tank filter elements and return line hardware
Head to the Oil Tank section on page 92, which carries through page 93 and lists the reservoir, filter elements, and fittings by part number. For the return-line parts between the control valve and tank, also turn to Oil Piping Return C V Tank on page 170. Match your existing numbers against both lists before you order replacements.
Manual Section: 0044 Oil Tank p. 92One track drives slower than the other, drive motor internal parts hard to identify from diagrams
Locate Drive Motor Component Parts beginning on page 84; it runs across two sections, pages 84-87. Read the 0040 and 0041 exploded views together for the full motor component list. Match each part by item number in both diagrams, then check the parts-list columns on those pages to confirm the right numbers before ordering.
Manual Section: 0040 Drive Motor Component Parts 1 p. 84Engine hard to start after sitting, fuel filter and injection component part numbers needed
Find fuel system parts across 2 sections: Fuel Piping on page 62 and Nozzle Holder Glow Plug on page 26. The Fuel Piping section (pages 62-63) covers the filter assembly, fuel lines, and line fittings by part number. For nozzle holders and glow plugs, the 2-page diagram starting at page 26 lists all injection-side components separately.
Manual Section: 0029 Fuel Piping p. 62Frequently Asked Questions
What are the replacement specifications for pins?
In the PISTON CRANKSHAFT group, the PISTON PIN carries part number 15521-21310 and weighs 0.156 kgf (0.3432 lb). The catalog lists it where you would order a replacement. p. 11
Does this manual help with a leaking boom cylinder rod seal on the KX101?
Yes. The Boom Cylinder Component Parts diagram on page 215 (running through page 216) shows an exploded view where every numbered position ties to a line in the parts list beside it. Work through each O-ring, wiper seal, and piston seal by position number to collect the matching part numbers for a full seal kit order (page 215). p. 215
How do I find undercarriage part numbers when the KX101 track keeps slipping off or running loose?
The manual splits the undercarriage across three sections: Idler on page 241, Truck Roller on page 243, and Crawler on page 245, running from page 241 through 246. Each exploded view lists its wear components and hardware by part number (page 241). Confirm the serial number range noted in every parts list before ordering, since undercarriage numbers can shift between production batches. p. 241
If one KX101 track drives slower than the other, can I identify the drive motor internal parts?
Yes. The Drive Motor Component Parts diagrams begin on page 84 and run across two sections, pages 84-87. Read the 0040 and 0041 exploded views together for the full motor component list, match each part by item number in both diagrams, then check the parts-list columns on those pages to confirm the right numbers before ordering (page 84). p. 84
Where are the hydraulic oil tank filter elements and return-line parts for the KX101?
The Oil Tank section starts on page 92 and carries through page 93, listing the reservoir, filter elements, and fittings by part number (page 92). For the return-line parts between the control valve and tank, turn to Oil Piping Return C V Tank on page 170. Match your existing numbers against both lists before ordering replacements. p. 92
