Kubota Mini Digger Engine Sump Repair – Split Sump Welded and Over-Plated

A gouged or split engine sump on a Kubota mini digger can usually be welded and repaired instead of replaced. Simply Welding repaired a gouged and split engine sump from a Kubota mini digger. We removed the damaged sump, seam welded the split, over-plated the area for extra strength and had the digger back at work the following day, saving the customer the cost and wait of a new sump.

Job Description

We carried out a quick, simple welding repair on a gouged and split engine sump from a Kubota mini digger.

Material Used

Consumables and a small amount of 2mm plate.

Repair Process

The sump was removed from the digger, the gouge was knocked out and the split was seam welded. The area was ground flat, then over-plated with 2mm plate, which was fully seam welded around its perimeter. The split had already been welded shut, so the over-plate was belt and braces, giving extra protection over the repair.

Final Prep

Once cooled, the welded perimeter was sealed with Sikaflex seam sealer, and the sump was painted and refitted.

Result

The sump was leak-free and the Kubota mini digger was back at work the following day.

Frequently Asked Questions

Can a damaged mini digger sump be welded?

Yes. A gouged or split steel sump can be removed, seam welded, ground flat and over-plated for extra strength, then sealed, painted and refitted, usually much quicker and cheaper than buying a new sump.

Why over-plate the sump after welding the split?

The split was already fully seam welded shut, so the over-plate was belt and braces. A 2mm plate, fully seam welded around its perimeter, gives extra protection over the repaired area where the sump was gouged.

How long does a sump repair take?

This was a quick, simple repair. The sump was removed, welded, over-plated, sealed, painted and refitted, and the Kubota mini digger was back at work the following day.
