Product Details
Product Overview
This high-quality engine piston kit, identified by part number 1G770-2111 (also available as 1G770-21110 and 1G770-21111), is a direct replacement component for Kubota D1503, V1503, and V2003 series diesel engines. Designed as a complete kit, it includes the piston, piston pin, and retaining clips, providing everything needed for a reliable rebuild or replacement.
Machined to a standard bore size of 83.00mm and featuring a 25.00mm pin diameter, this kit is engineered for direct injection (DI) diesel engines commonly found in compact construction and agricultural machinery. It is a crucial component for maintaining engine compression, power output, and fuel efficiency in Kubota-powered equipment.
Key Features & Benefits
Complete Kit: Includes the piston, wrist pin, and clips, ensuring a hassle-free installation without sourcing individual parts.
Precision Engineering: Manufactured to exact OEM specifications with a standard 83.00mm bore size and 25.00mm pin diameter for a perfect fit in D1503, V1503, and V2003 engines.
Durable Material: Constructed from high-silicon aluminum alloy with a molybdenum disulfide (MoS2) coated skirt, offering excellent wear resistance, reduced friction, and improved thermal stability.
Enhanced Performance: The MoS2 coating on the skirt reduces piston slap and noise during cold starts while improving cylinder wall lubrication for longer engine life.
Application Versatility: Suitable for a wide range of equipment, including tractors, excavators, skid steer loaders, and forklifts powered by Kubota V2003-DI, V1503-DI, and D1503-DI engines.
Fit Confidence: Direct cross-reference to OEM part numbers 1G770-2111, 1G770-21110, and 1G770-21111 ensures compatibility with original Kubota specifications.

FAQ
Q1: Will this piston kit fit my Kubota V2003 engine if the engine code is slightly different? This kit is designed for Kubota D1503, V1503, and V2003 engines with direct injection (DI). To ensure a perfect fit, please verify your engine’s block casting number or existing piston part number. If your engine is a V2003 but uses a different piston code (e.g., 1G770-2112 for oversized), this standard 83mm kit will not fit. Always compare your old piston’s diameter and pin size before purchase.
Q2: Can I install this piston kit without replacing the cylinder liners? Yes, this is a standard size (STD) piston kit intended for engines with original or unworn cylinder bores. If your cylinder liners show signs of scoring, wear, or are out of round, they should be replaced or honed to specification before installing new pistons. For engines requiring oversized pistons, please look for our +0.25mm, +0.50mm, or +0.75mm variants.
Q3: What is the purpose of the MoS2 coating on the piston skirt? The molybdenum disulfide (MoS2) coating on the piston skirt reduces friction between the piston and cylinder wall during operation. This coating provides several benefits: it decreases engine wear during cold starts, reduces piston slap noise, improves fuel efficiency by lowering internal friction, and enhances the overall durability of the piston assembly in high-temperature diesel applications.
