3069020X Rocker Lever (LEVER,ROCKER), also known as rocker arm, is a key transmission component of valve train for CUMMINS series diesel engines. It converts upward thrust from push rod into downward force to actuate intake and exhaust valves, coordinating the regular gas exchange cycle of the engine.
This rocker lever solves common failures including contact surface wear, abnormal knocking noise, disordered valve timing and insufficient power caused by long-term impact load and metal fatigue.
Core Product Advantages
High-Strength Alloy Casting Material
Premium alloy raw material with outstanding mechanical strength, resist alternating impact load, avoid fracture and deformation under continuous heavy-duty operation.
Precision Machined Contact Surfaces
Finer grinding treatment on friction contact positions, low wear rate, effectively reduce noise during operation and maintain stable valve clearance.
Good Thermal Stability
Small thermal deformation under high temperature environment inside cylinder head, guarantee accurate valve movement timing.
Surface Hardening Treatment
Enhanced wear resistance, extend service life under frequent reciprocating motion.
Standard Matching Specification
Dimension 17cm15cm13cm, weight 1.2KG, perfectly fit supporting CUMMINS engine cylinder head assembly, direct replacement without modification.
Strict Factory Quality Inspection
All rocker levers pass dimensional inspection, hardness testing and appearance screening, stable batch quality for engine overhaul factories and engineering fleets bulk procurement.
