TIMING
ADVANCED SURFACE SUPERIOR STEEL
SPROCKETS
Tested for excellence
NAPA Sprockets are made from two different types of materials: steel or powder metal. Steel sprockets undergo a forging process that involves shaping the metal through intense heat and pressure. Conversely, powder metal sprockets are created using powder metallurgy, a method that compacts and sinters metal powders.
These sprockets undergo comprehensive testing, including checks for dimensions, hardness, profile, and flaw detection, ensuring the highest quality and reliability.
HARDNESS TESTED DIMENSION TESTED
VVT SPROCKETS
High-quality components
The main components of VVT (Variable Valve Timing) are constructed using highquality steel and aluminum. These components are manufactured with advanced CNC (Computer Numerical Control) machines and undergo rigorous performance testing to ensure their reliability and longevity.
These performance tests consist of evaluating critical parameters such as lifting pin pressure, friction torque, leakage, locking functionality, and locking pin clearance to guarantee the overall functionality and durability of the VVT components.
HIGH FRICTION TORQUE TESTED
STEEL AND ALUMINIUM HIGH GRADE PERFORMANCE LEAKAGE AND LOCKAGE
TENSIONERS & GUIDES
NAPA Tensioners are primarily crafted from sturdy steel and lightweight aluminium. They are meticulously manufactured using high-precision CNC machines and subjected to thorough 100% tightness tests on their critical components. During performance testing, the static oil pressure and dynamic damping force are
