A Pushrod calculation tool is useful for a mechanic or a DIY enthusiast. If you e]want to know the perfect optimal length of push rods for your engine. Simply enter overall length and ball diameter the calculator evaluate the required length in the result field.
In the engine valvetrain system, pushrod length is an important measurement. Pushrods are used in overhead valve engines to transfer the motion from the camshaft to the valve lifter or rocker arm and, therefore, to actuate the valves. Correct length results in proper valve timing and clearance,. Performance and efficiency are two very important considerations for good engine.
User Guide
| Input | Action |
|---|---|

Calculation Example 1
Here’s how to determine the pushrod length.
| Step | Calculation |
|---|---|
| Overall Length (OL) | 8.5 inches |
| Ball Diameter (BD) | 0.5 inches |
| Divide BD by 2 |
|
| Subtract from OL |
inches |
Answer: The pushrod length is 8.25 inches
