The formula to calculate the Pushrod Length (PR) is:
\[ \text{PR} = \text{OL} - \frac{\text{BD}}{2} \]
Where:
The pushrod length is the distance from the center of the ball at one end of the pushrod to the center of the ball at the other end. It is a critical measurement in engine assembly and tuning.
Let's consider an example:
Using the formula to calculate the Pushrod Length:
\[ \text{PR} = 8 - \frac{1}{2} = 7.5 \, \text{inches} \]
This demonstrates that with an overall length of 8 inches and a ball diameter of 1 inch, the pushrod length would be 7.5 inches.
