The addition of a roller tip allows the rocker arm to "roll" across the top of the valve stem, thereby reducing friction by a substantial amount. Also, the roller tip cannot side-load the valve within the valve stem, thereby providing an additional reduction in frictional losses in the valve train.AT142 Rocker arm It Ifl 2141Y ±0---?t4 122 3. 0g#AT4 4- Vr:. 11):1 1/01 A-A Dreaweby: B
