Kubota U27-4 HI Mini Excavator Parts Manual (BKIDA5125)

The Kubota U27-4 HI is a small rubber-track mini excavator, the kind you’d see on a landscape job or doing trenching where a full-size hoe won’t fit. The Kubota U27-4 HI parts manual is what you grab when you’re trying to figure out exactly which pin, bushing, seal kit, or bracket you’ve got before you start tearing in. I treat it the same way I use the book for my BX and my L3901: it’s my map when I’d rather order parts once and skip three trips to the dealer. If you’re trying to identify hard parts and plan a repair, this is the right type of book.

What this manual helps you do

• Identify the correct OEM part numbers for boom, arm, and bucket pins, bushings, and linkages before a pivot rebuild.
• Locate the exact hydraulic cylinder seal kits, hoses, and fittings used on the U27-4 HI’s boom, arm, and blade circuits.
• Look up undercarriage components like track rollers, idlers, sprockets, and rubber tracks so you can price out a full or partial undercarriage job.
• Cross-reference older Kubota part numbers to the current numbers shown in the diagrams and parts lists when ordering from a dealer.
• Verify the small stuff—clips, bolts, shims, covers, electrical connectors—so you’re not guessing at hardware or ordering the wrong little bits.

Who this is for

This parts manual is aimed at an independent mechanic, a farm or rental-yard owner running their own mini ex, or Kubota dealer parts staff who need accurate part numbers fast. If you’re after torque specs, step‑by‑step teardown procedures, or hydraulic testing instructions, you want the Workshop/Service Manual, not this parts catalog.
