Kubota 629, 619B Backhoe Parts Manual

The Kubota 629, 619B Backhoe is an attachment backhoe you’ll see hanging off the back of compact and utility tractors on farms and small jobsites. The Kubota 629, 619B parts manual is what I’d reach for at the bench when a customer backs in with a leaking cylinder, a sloppy boom pin, or a busted bucket linkage and we need to see how it all stacks together. Most folks use this kind of book to identify the exact part number before ordering, or to see every bushing, seal, and fastener in an assembly before they tear it apart.

What this manual helps you do

• Identify every OEM Kubota part number on the 629 and 619B backhoe, from major castings down to pins, clips, seals, and hardware.
• Locate where a mystery part belongs by using exploded diagrams of the boom, dipper, bucket, swing frame, stabilizers, controls, and mounts.
• Look up the correct quantity of small parts (like o-rings, shims, and bolts) so you order everything once and don’t lose a day waiting on one missing piece.
• Cross-reference older Kubota part numbers to the newer superseded numbers your dealer’s computer actually recognizes.
• Verify that the parts you find used or from aftermarket suppliers match the original Kubota references before you spend money.

Who this is for

This suits an independent ag mechanic, farm owner-operator, small contractor, or anyone running or maintaining a Kubota 629 or 619B backhoe and wanting to save money by ordering parts smart. If you’re looking for torque specs, hydraulic test procedures, or step-by-step repair instructions, you need the Workshop/Service Manual, not this parts catalog.
