X10012648 Eccentric Shaft is a precision offset rotary component installed inside JAC YND30TCIF diesel engine balance chamber. It works in paired rotation to generate counteracting inertia force and offset the inherent shaking force produced by piston reciprocating movement. This aftermarket eccentric shaft eliminates harsh engine vibration, abnormal rattling and accelerated accessory wear caused by journal scoring, bending deformation and unbalanced mass after long cycles of high-speed variable load. Stable vibration suppression enhances driving comfort and extends service life of peripheral components for JAC light commercial vehicles engaged in urban distribution and inter-town short haulage.
Product Advantages Manufactured from high-grade alloy steel with integral quenching treatment for superior rigidity and wear resistance. Eccentric cam profile is precision machined to guarantee accurate counterweight phase. Journals are finely finished to form stable oil film with bearing shells. Every eccentric shaft undergoes dynamic balance calibration and runout detection before packaging, OEM mounting hole layout and journal dimension for smooth balance system overhaul.

FAQ
Q1: What obvious phenomenon will occur if the eccentric shaft or its bearing wears severely?
A1: Obvious low-frequency vibration throughout the engine and rhythmic knocking sound from the crankcase side.
Q2: Why must we confirm timing marks during assembly of paired eccentric shafts?
A2: Misaligned phase cancels out the damping effect and may amplify vibration instead of reducing it.
Q3: What parts should be replaced together with this eccentric shaft?
A3: It is recommended to renew matching bearing shells, thrust washers and oil seals as a complete set.
Q4: What inspection item cannot be omitted after installation?
A4: Rotate the shaft manually to verify free rotation without binding and measure journal clearance.
