| ?UNNATURAL VALVE MOTION |
| |
| ACCELERATION |
The Camshaft applies load on the Valve. |
| DECELERATION |
The load from the Valve Spring pushing the Valve up. |

?JUMP
When the cam lob passes the peak point of the lobe and the valve lifter then returns, there are time when the valve spring is not capable to keep up with the large cam lift design and causes the valve to crash into the cam. This can cause the valve to jump and or bounce repeatedly. Left unattended to can lead to terminal engine failure. |
 |
?BOUNCE
When the valve closes after contacting and not staying seated the shock can cause the valve to rebound repetitively causing damage. |
|
| |
| Due to the phenomenon of the Valves movement following the Camshaft the impact on the Cam and the Valve seat is great enough to cause damage to the Valve and there are times when the abnormal rebound can cause contact with the Piston. The phenomenon easily occurs when the motion of the Valves mass is great so attention to detail of the weight of the dynamic Valve Train is vital. |

| ?SURFACE TREATMENT |
|
| This surface treatment used on these retainers is the latest technology in surface treatment. This treatment to the material will change the materials surface to enhance its properties in scratch resistance, wear resistance, heat resistance and corrosion resistance. |
