Product Overview
3070175 Valve Crosshead (CROSSHEAD,VALVE) is an important force transfer part inside Cummins series diesel engine valve chamber. Installed between rocker arm and engine valves, it transfers the thrust of rocker arm evenly to intake and exhaust valves, realizing stable opening and closing action of valves.
This valve crosshead effectively solves common faults such as crosshead surface wear, valve asynchronous movement, valve train abnormal knocking and power drop caused by abrasion, deformation and fatigue damage of old crossheads.
Core Product Advantages
High-Strength Alloy Precision Casting
Integrated casting and heat treatment process, high hardness and impact resistance, withstand frequent reciprocating impact load without cracking or deformation.
Precision Contact Surface Machining
Contact surface fine grinding, smooth matching with valve stem top, uniform stress distribution, reduce point abrasion and avoid valve stem damage.
Optimized Force Transmission Structure
Scientific structural design ensures balanced force output, keeps synchronous movement of multiple valves, prevents uneven valve clearance.
Wide Temperature Adaptability
Stable mechanical performance within -40℃ ~ +135℃, no thermal deformation under long-term high temperature inside valve chamber.
Anti-Oxidation Surface Treatment
Surface passivation treatment resists erosion of high-temperature engine oil and oil vapor, slow down surface oxidation and abrasion.
Standard Matching Specification
Dimension 8cm2cm2cm, weight 0.153KG, perfectly match Cummins engine valve train assembly, plug-and-play replacement without grinding modification.
Strict Factory Hardness & Dimension Inspection
All crossheads pass hardness test, dimensional tolerance detection and impact cycle test, stable batch quality for engine overhaul and fleet bulk procurement.
