Product Description
1006011FB060PK Eccentric Shaft is a precision offset balance component installed inside the crankcase of JAC HFC4DB2-2E diesel engine. It rotates synchronously with crankshaft to generate reverse inertial force, offsetting the shaking force produced by reciprocating pistons and lowering overall engine vibration. This aftermarket replacement shaft resolves persistent rough shaking, rhythmic knocking and premature wear of oil seals and bearings caused by journal scoring, out-of-tolerance bending and lost dynamic balance after repeated variable load cycles. Stable vibration suppression protects engine internals and delivers smoother driving experience for JAC pickup and light commercial vehicles used in city delivery and suburban freight routes.
Product Advantages Forged from premium alloy steel with quenching and tempering treatment, offering excellent fatigue resistance and structural rigidity. The eccentric profile is precisely machined to guarantee accurate counterweight phase. Main journals receive surface hardening treatment to maintain stable oil film and reduce friction. Every eccentric shaft passes dynamic balance calibration and runout inspection before shipment, OEM journal size and mounting hole layout for trouble-free balance system overhaul.

FAQ
Q1: What obvious sign indicates that the eccentric balance shaft has worn journals?
A1: Noticeable low-frequency vibration that intensifies with engine speed, plus knocking noise from crankcase.
Q2: What will happen if the timing marks of paired eccentric shafts are mismatched?
A2: The counteracting force deviates, vibration cannot be reduced and may even become aggravated.
Q3: What supporting parts should be replaced together during overhaul?
A3: It is recommended to renew matching bearing shells, thrust washers and shaft oil seals as a set.
Q4: What check must be completed after installation?
A4: Rotate the shaft manually to confirm free rotation without binding and measure bearing clearance.
