For Kubota D1305 Diesel engine assembly 3000rpm 21.4KW Excavator Engine Parts

Specification

Product Details

Description

The Kubota D1305 diesel engine assembly is a core power component designed for small excavators. With a displacement of 1.26L and a rated power of 21.4KW/3000rpm, it adopts a 3-cylinder water-cooled naturally aspirated structure, compatible with the power systems of Kubota and supporting brand small excavators. This assembly integrates full accessories (such as generator, starter motor, cooling fan), and can directly replace the original engine as a power unit, serving as a key power part to ensure efficient excavator operation.

Advantage

High Compatibility:Custom-designed for small excavators, with interfaces and installation dimensions fully matching original models; the assembly design allows direct hoisting replacement without additional adaptation.
Efficient Power:Outputs stable 21.4KW power at 3000rpm, with high power density, suitable for heavy-duty working conditions (such as excavation and rotation) of excavators.
Durable & Reliable:Based on Kubota’s mature "05 series" technology, adopts spherical combustion chamber + micro injection system, resistant to high-frequency start-stop and harsh working conditions of construction machinery, with low failure rate.
Lightweight Design:The whole machine weighs only about 95kg, effectively reducing the overall weight of the excavator and improving operation flexibility.

Performance

Basic Parameters:3-cylinder water-cooled 4-stroke diesel engine, displacement 1.26L, cylinder bore × stroke 78mm × 88mm.
Power Output:Rated power 21.4KW/3000rpm, maximum torque about 80Nm/1700rpm.
Operating Parameters:Idle speed 1000-1100rpm, compression ratio 24:1.
Supporting Systems:Integrates 12V starting system, forced lubrication system, water-cooled heat dissipation system, compatible with excavator hydraulic system load.
