Pushrod Length Calculator

Formula

The formula to calculate the Pushrod Length (PR) is:

\[ \text{PR} = \text{OL} - \frac{\text{BD}}{2} \]

Where:

\( \text{PR} \) is the Pushrod Length (inches)
\( \text{OL} \) is the Overall Length (inches)
\( \text{BD} \) is the Ball Diameter (inches)

Pushrod Length Definition

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.

Example Calculation

Let's consider an example:

Overall Length (OL): 8 inches
Ball Diameter (BD): 1 inch

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.
