Brand: Komotashi

Kubota Cylinder Block (V2403 Engine)

✓ Product: Cylinder Block
✓ For Kubota V2403 Diesel Engine
✓ Widely used for mini excavators, wheel loaders, forklifts, agricultural tractors, small generator engine overhaul

Kubota V2403 cylinder block is the core load-bearing foundation component for V2403 four-cylinder industrial diesel engine. It is cast from high-strength wear-resistant alloy cast iron with integrated lubricating oil galleries and cooling water channels. It can withstand long-term alternating impact loads, continuous high temperature and pressure, serving as a critical OEM replacement part for overhauling agricultural machinery and compact construction equipment.

Overview

Product Details

Product Name: Cylinder BlockApplicable Engine: Kubota V2403Material: High-strength wear-resistant alloy cast ironMatching Equipment: Mini Excavators, Wheel Loaders, Forklifts, Agricultural Tractors, Small Generator Sets

Manufactured strictly following OEM dimensional tolerances for direct bolt-on replacement without modification. Main bearing saddles, cylinder bores and mounting joint surfaces are precisely bored and milled to ensure excellent coaxiality and flatness for accurate assembly. Optimized internal flow channel design delivers stable lubricant circulation and uniform heat dissipation. All cylinder blocks undergo non-destructive flaw detection and hydraulic pressure leakage testing before shipment. Bare cylinder blocks and cylinder blocks pre-installed with dry cylinder liners are both available for supply.

Product Advantages

High Rigidity Alloy Cast Iron Structure

Premium wear-resistant alloy cast iron material with superior structural rigidity, outstanding anti-deformation and anti-cracking performance, ideal for dusty farm and construction heavy-duty working environments
Integrally formed oil and cooling water passages eliminate joint leakage risks and effectively reduce oil seepage and coolant leakage faults during long-term service
Compact vertical four-cylinder layout supports prolonged continuous high-torque low-speed operation and extends overall engine service lifespan

Precision OEM Standard Machining

Fully machined to original factory drawing tolerance standards, zero dimensional deviation on all hole positions and mounting surfaces for seamless assembly
High-precision finishing of main bearing housings avoids eccentric crankshaft wear and prolongs service life of crankshaft and bearing shells
Ultra-fine machining on sealing surfaces thoroughly prevents oil, water and air leakage after installation, cutting one-time overhaul failure rates

Wide Matching & Stable Aftermarket Supply

Specially matched with Kubota V2403 naturally aspirated and turbocharged power units, compatible with a full range of small agricultural and construction machinery models
Mature aftermarket spare part with abundant stock and fast delivery turnaround
Flexible supply options: bulk customization of bare cylinder blocks or finished assemblies pre-fitted with cylinder liners
