Product Description
1006020FD020ZCPK Valve Rocker Arm is a pivotal lever component inside the valve train of JAC HFC4DB2-1D diesel engine. It transfers lifting force from camshaft and tappet to intake and exhaust valves, governing the opening timing and lift stroke to realize air exchange cycles. This aftermarket rocker arm resolves irregular valve action, noisy valve train and power decline caused by worn roller surface, fractured arm body and distorted pivot bore after enduring repeated impact load. Stable valve actuation maintains precise valve timing and helps light-duty vehicles keep steady performance during frequent stop-and-go urban delivery and suburban freight operations.
Product Advantages Forged from high-strength alloy steel with quenching treatment for outstanding rigidity and fatigue resistance. The integrated roller adopts wear-resistant bearing structure to lower sliding friction and cam abrasion. Precision machining on pivot hole and valve contact end ensures consistent force transmission. Each rocker arm undergoes dimensional inspection and roller rotation test before shipment, OEM mounting size and outline for direct valve train overhaul.
