Are you tired of using makeshift tools to measure your pushrods? Do you want to ensure the precise measurement of your engine’s valve train? Look no further than the pushrod measuring tool. In this ultimate guide, we’ll cover everything you need to know about this essential tool.
What is a Pushrod Measuring Tool?
A pushrod measuring tool is a specialized device used to measure the length of an engine’s pushrods accurately. It is commonly used in high-performance and racing engines, where precise measurements are critical for optimal performance.
Why Use a Pushrod Measuring Tool?
Using a pushrod measuring tool eliminates the guesswork involved in determining the correct length of pushrods needed for an engine. A slight variation in pushrod length can significantly impact valve timing and performance.
How Does a Pushrod Measuring Tool Work?
The tool consists of two pieces – a base and an adjustable bridge. The base sits on top of the lifter bore, and the bridge slides over the pushrod. The adjustable bridge allows for precise measurements as it provides a reference point for determining the length of the pushrod required.
Types of Pushrod Measuring Tools
There are two types of pushrod measuring tools – manual and digital.
Manual Pushrod Measuring Tool
The manual pushrod measuring tool is the most common type and consists of a dial indicator that measures the distance between two points. This device is easy to use, affordable, and provides accurate measurements.
Digital Pushrod Measuring Tool
The digital pushrod measuring tool uses electronic sensors to measure distances digitally. It offers greater accuracy than manual tools but comes at a higher price point.
How to Use a Pushrod Measuring Tool
Using a pushrod measuring tool requires some knowledge and skill. Here’s how to do it:
Step 1: Remove the rocker arms from the cylinder head.
Step 2: Insert the pushrod through the lifter bore.
Step 3: Place the measuring base on top of the lifter bore and adjust the bridge to touch the pushrod’s end.
Step 4: Take the measurement using either a manual or digital dial indicator.
Step 5: Repeat this process for each pushrod, noting down the measurements for reference.
Tips for Using a Pushrod Measuring Tool
– Ensure that the engine is at room temperature before taking measurements.
– Clean all parts thoroughly before use to avoid any dirt or debris affecting your measurements.
– Measure both intake and exhaust valve pushrods separately as they may vary in length.
– Record all measurements accurately to ensure proper assembly of the engine.
Conclusion
A pushrod measuring tool is an essential tool for any engine builder or mechanic looking to optimize their engine’s performance. With its precise measurements, it eliminates guesswork and ensures that your engine’s valve train operates optimally. Whether you opt for a manual or digital pushrod measuring tool, be sure to follow our tips for accurate results.
