Kubota LB400 Front Loader Parts Manual (BKIDA0087)

The Kubota LB400 is a front loader that hangs off the front of your tractor for moving manure, gravel, bales, and dirt. The Kubota LB400 parts manual is what parts counters, farm owners, and independent mechanics grab when they’re trying to ID pins, cylinders, hoses, and brackets before the loader comes apart. If you’re staring at a worn pivot, bent bucket linkage, or leaking cylinder and need the correct Kubota part number, this is the right kind of book. If you’re hoping for repair steps or torque specs, that’s a different manual.

What this manual helps you do

• Identify every component on the LB400 front loader using exploded diagrams, from bucket cutting edge and pins to lift and tilt cylinders.
• Locate the exact OEM Kubota part numbers so you can order the right pins, bushings, seal kits, hoses, and brackets the first time.
• Look up quantity-per-loader for hardware, seals, and small parts so you don’t come up short with the tractor sitting in the field during planting or harvest.
• Cross-reference older LB400 part numbers to newer superseded Kubota numbers when the dealer’s system shows a replacement.
• Verify that a used or aftermarket part actually matches the BKIDA0087 Kubota LB400 front loader parts breakdown before you bolt it on.

Who this is for

This parts manual is aimed at the independent ag mechanic, farm owner-operator, Kubota dealer parts staff, and anyone maintaining a loader fleet who needs fast, accurate part ID to cut downtime. If you need torque values, step‑by‑step repair procedures, or adjustment specs, you want the Kubota workshop/service manual, not this LB400 parts catalog.
