| High Light | 8-97071673-0 OEM Fit Valve Push Rod ，4JH1 4JB1 4JG2 Engine Push Rod ，Hardened End Tips Valve Push Rod | ||
Valve Push Rod 8-97071673-0 / 8970716730 — a verified OEM-fit engine valve tappet rod for ISUZU NKR77, NPR, NKR55, NHR, NLR, NMR series trucks equipped with 4JH1, 4JB1, 4JG2, 4JA1, and 4JC1 diesel engines.
This push rod is a critical transmission element of the engine valvetrain, responsible for precisely transferring camshaft motion to the valve and controlling valve opening and closing timing.
The valve push rod is a rigid rod that connects the camshaft (via the tappet) to the rocker arm, or directly actuates the valve in the valvetrain. As the camshaft rotates, the cam lobe lift pushes the tappet, which in turn drives the push rod in reciprocating linear motion. The push rod then transmits this motion to the rocker arm, ultimately opening and closing the valve according to the valve timing requirements.
The push rod must possess both high axial stiffness (to prevent bending that would cause valve timing errors) and lightweight construction (to reduce reciprocating inertia forces). Both ends are typically hardened to resist high-frequency wear at the contact surfaces with the tappet and rocker arm.
The 4JH1 is a 3.0L inline-four diesel engine and the 4JB1 is a 2.8L inline-four diesel engine, both widely used in ISUZU NKR/NPR series trucks and extensively applied in Hitachi, JCB, Doosan and other construction equipment.
Replace the push rod when any of these symptoms appear:
