The 13801-11012 valve rocker arm is specifically designed for the 1GD/2GD engines of Toyota HILUX REVO, from the size specifications of the valve rocker arm to the precision of its fit with the camshaft and valve stem,
All are precision manufactured strictly in accordance with the original design standards of the engine. Both 1GD engines require high precision in gas distribution for daily urban commuting, in order to achieve smooth power transmission
Good fuel economy; The 2GD engine still faces severe tests on the reliability and durability of the valve rocker arm under complex working conditions such as off-road and heavy-duty transportation in the suburbs,
As long as it is a Toyota HILUX REVO equipped with 1GD/2GD engines, the valve rocker arm can achieve perfect adaptation. The installation process follows Toyota's original factory standard procedures, which are simple and fast,
Without the need for complex modifications to the engine valve system, it can be easily installed in place, ensuring seamless integration with the overall engine valve system, stable and collaborative work, and laying a solid foundation for the reliable operation of the engine.
The valve rocker arm adopts an optimized lever structure, and its arm length is precisely calculated and designed to efficiently transmit the force of the camshaft,
Drive valve opening and closing with minimal energy loss. When the engine is working, the rotation of the camshaft pushes one end of the valve rocker arm, and through the lever principle,
The other end of the rocker arm precisely transmits force to the valve stem, causing the valve to open and close according to the predetermined time and stroke. This optimized lever structure not only improves valve distribution efficiency,
It can also effectively reduce the impact and vibration during valve opening and closing, making the engine's valve timing process smoother and more stable. For example, when the engine is running at high speed,
The valve rocker arm can quickly respond to the movement of the camshaft, accurately control the opening time of the valve, ensure sufficient intake and smooth exhaust, and provide strong power support for the engine.
The pivot part of the valve rocker arm adopts high-precision machining technology, with extremely low surface roughness,
The clearance between the rocker arm seat is controlled within a very small range. This enables the valve rocker arm to maintain extremely high flexibility and stability during rotation,
Reduce energy loss and wear caused by friction and shaking. At the same time, the surface of the valve rocker arm in contact with the camshaft and valve stem has undergone special treatment,
The use of high hardness and wear-resistant material coating can effectively resist frequent impact and friction between the camshaft and valve stem, extending the service life of the valve rocker arm.
During the long-term operation of the engine, the high-precision pivot and contact surface can ensure that the valve rocker arm always works stably, ensuring the accuracy and reliability of the valve system.
