4022824 / 3076046 Push Rod (ROD,PUSH) is an important transmission part of valve train for CUMMINS series diesel engines. It transmits the thrust from camshaft tappet to rocker arm, driving regular opening and closing of intake and exhaust valves to complete engine gas exchange.
This push rod solves common faults such as push rod bending, fracture, abnormal engine knocking and insufficient power caused by metal fatigue and impact load.
Core Product Advantages
High-Strength Precision Tube Material
High-quality alloy pipe raw material, integral processing, strong compression resistance, effectively avoid bending deformation under alternating impact load.
Hardened End Heads
Both ends undergo surface strengthening treatment, excellent wear resistance, reduce abrasion with tappet and rocker arm contact surfaces.
Strict Straightness Control
Precision straightening processing ensures excellent linearity, guarantees accurate valve timing and prevents valve clearance disorder.
Stable Performance Under High Temperature
Small thermal deformation inside engine, maintain stable transmission effect under long-term continuous operation.
Anti-Oxidation Surface Treatment
Anti-rust treatment slows surface corrosion during storage and operation.
Standard Matching Specification
Dimension 18cm3.7cm3.7cm, weight 0.2KG, perfectly match supporting CUMMINS engine valve assembly, direct replacement without modification.
Strict Factory Quality Inspection
All push rods pass straightness inspection, compression resistance test and appearance screening, stable batch quality for engine overhaul factories and engineering fleets bulk procurement.
