2864028 Cylinder Head Fits Cummins Engine Top Assembly Replacement Spare Part

Product Overview

2864028X Cylinder Head (HEAD,CYLINDER) is one of the most critical assemblies of Cummins series diesel engines. Installed on top of cylinder block, it forms sealed combustion space together with piston and cylinder liner. It integrates intake & exhaust passages, cooling water channels, valve mounting seats and injector installation holes to realize air intake, exhaust and fuel injection.

This cylinder head solves major engine failures such as air leakage, water channel crack, oil channel seepage, insufficient power and white smoke caused by deformation, cracking and plane warping of old cylinder heads, which is essential for engine major overhaul.

Core Product Advantages

1. High-Strength Alloy Cast Integral Structure

   Special high tensile cast alloy casting, excellent thermal fatigue resistance, withstand alternating high temperature and pressure inside combustion chamber, resist crack and deformation.

2. Precision Machined Sealing Surface

   Strict flatness control on bottom mating surface, guarantee tight fit with cylinder gasket, effectively prevent gas leakage, coolant leakage and engine oil seepage.

3. Optimized Water & Oil Passage Layout

   Smooth internal cooling water galleries and lubricating oil passages, uniform heat dissipation, avoid local overheating, reduce thermal stress and prevent cylinder head cracking.

4. Precision Valve Seat & Injector Hole Machining

   Accurate valve seat bore and injector mounting holes, ensure stable valve sealing and normal fuel injection performance, maintain good combustion efficiency.

5. Wide Temperature Alternation Adaptability

   Stable structural performance under frequent cold and hot cycles, suitable for long-time heavy-load continuous operation of diesel engines.

6. Standard Matching Installation Specification

   Dimension 108cm41cm37cm, weight 115KG, perfectly match supporting Cummins engine cylinder block, direct overhaul replacement without large-scale machining.

7. Strict Multi-Process Factory Inspection

   All cylinder heads pass hydraulic pressure leakage test, flatness inspection, flaw detection and dimensional verification, stable batch quality for engine overhaul factories and large fleets bulk procurement.
