Giuqa D722 Piston for Kubota Engine Aluminum

Description

Product Overview

The Giuqa D722 piston is engineered for Kubota D722 series engines, offering a precision‑machined aluminum construction with a +0.5 mm (0.02 inch) oversize. Standard piston diameter is 67 mm; this model measures 67.5 mm to provide a tighter clearance and enhanced wear resistance. Manufactured by Giuqa, the piston features a forged aluminum alloy body, high‑strength piston rings, and a design optimized for the D722, D722EBH, and D772B engine families. Compatibility details and part numbers are clearly listed to reduce ordering errors.

Usage

Designed for both professional workshops and home garages, this piston fits seamlessly into routine engine rebuilds, performance upgrades, and maintenance overhauls. It is ideal for agricultural equipment, small tractors, and utility engines where Kubota D722 power units are standard. Installers should verify engine model and consult the nameplate before ordering to ensure the correct oversize fit.

FAQ

Is this piston a direct replacement for the stock Kubota piston?

It is an oversize replacement. If your engine requires the standard 67 mm size, contact us for the appropriate part.

Can I use this piston in a D722EBH engine?

Yes, the piston is compatible with D722EBH and D772B variants, providing the same oversize benefit.

Do I need to replace the piston rings when installing this piston?

We recommend installing the included high‑quality rings to ensure optimal sealing and performance.

What information should I provide when ordering?

Please supply your exact engine model or a clear photo of the engine nameplate to confirm compatibility.

How does the oversize dimension affect engine performance?

The +0.5 mm increase reduces piston slap and improves compression, leading to smoother operation and potentially longer engine life.
