Kubota D04 S4KT Cylinder Block

Demo Kubota Cylinder Block (D04 S4KT Engine)

✓ Product: Cylinder Block
✓ For Kubota D04 S4KT Diesel Engine
✓ Widely used for mini excavators, wheel loaders, forklifts, agricultural tractors, small generator engine overhaul

Kubota D04 S4KT cylinder block is the core load-bearing foundation component for D04 S4KT industrial diesel engine. It is manufactured from high-strength wear-resistant alloy cast iron with integrally cast lubricating oil passages and cooling water channels. Capable of enduring alternating impact loads, high temperature and high pressure under long-term operation, it serves as a key replacement part for engine overhaul of construction machinery and agricultural equipment.

Product Details

Product Name: Cylinder BlockApplicable Engine: Kubota D04 S4KTMaterial: High-strength wear-resistant alloy cast ironMatching Equipment: Mini Excavators, Wheel Loaders, Forklifts, Agricultural Tractors, Small Generator Sets

Manufactured strictly in accordance with OEM dimensional tolerances for direct replacement without modification. Main bearing housings, cylinder bores and mounting surfaces are precisely bored and milled to guarantee coaxiality and flatness for accurate assembly. Optimized internal flow channel design ensures smooth lubrication circulation and balanced heat dissipation. All cylinder blocks pass flaw detection and hydraulic pressure tightness testing before delivery. Bare cylinder blocks and cylinder blocks pre-fitted with cylinder liners are both available for supply.

Product Advantages

High Rigidity Alloy Cast Iron Structure

  • Premium wear-resistant alloy cast iron substrate with outstanding overall rigidity, excellent deformation and crack resistance, suitable for heavy-duty harsh working conditions such as dusty construction sites and farmlands
  • Integrally cast oil and cooling water passages eliminate splicing leakage risks and reduce oil and water failure rates in later service
  • Compact lightweight body structure supports long-duration continuous high-torque low-speed operation with extended service life

Precision OEM Standard Machining

  • Fully processed to the tolerance standards of original factory drawings with zero deviation in hole positions and mounting surfaces for perfect fitting during assembly
  • High-precision boring of main bearing housings prevents eccentric wear of crankshafts and extends the service life of crankshafts and bearings
  • Finely machined sealing surfaces eliminate oil, water and air leakage after installation, lowering failure rates for one-time overhaul assembly

Wide Matching & Stable Aftermarket Supply

  • Exclusively matched with Kubota D04 S4KT four-cylinder diesel power units for multiple models of small construction machinery
  • Mature aftermarket replacement spare parts with sufficient stock and fast delivery lead time
  • Flexible supply solutions: bulk customization of bare cylinder blocks or finished units pre-installed with dry cylinder liners
