How to Properly and Effectively Check Camshaft Run Out

To determine the performance of car components, it can be seen from the run out (bending) of the component. If the run out of a component is too high, the performance of that component will decrease. This also applies to the camshaft component. So how do you properly and effectively check the run out of the camshaft to ensure optimal camshaft performance? For more details, please pay attention to the following review.

How to Properly Check Camshaft Run Out

The performance of the camshaft can be said to be maximal if the run out is not too high. If the run out of this component is too high, the timing function of the valve opening and closing will have problems. As a result, the air mixture that enters does not match the specified ratio. This also occurs during the emission gas discharge process. Therefore, you need to know how to properly check the run out. Here are the complete steps.

1. Install the camshaft on the V-Block

The first step you need to take is to install the camshaft you want to check on the V-block.

2. Use a dial indicator

Next, you need to check the camshaft run out with the help of a dial indicator. Measure at the center of the camshaft for accuracy.

3. Compare the measurement results

Next, you need to compare the measurement results from the dial indicator with the standard specification values of the camshaft. If the measurement results from the dial indicator are higher than the maximum limit of the standard specification values of the camshaft, then you need to replace the camshaft with a new component. This also applies if the run out measurement results in a value of 0.8 mm.

4. Also check the camshaft journal and cam lobe

The last step, you need to check other parts of the camshaft such as the camshaft journal and cam lobe. The purpose of checking these components is to improve the accuracy of the results.

How to Check the Camshaft Journal

The correct way to check the camshaft journal is as follows.

First, prepare measuring tools such as an outer micrometer that has been calibrated.
Then set the outer micrometer value before you use it. Make sure the value is at zero "0".
Next, measure the camshaft journal with the outer micrometer. Then compare the measurement results with the specification values of your car.

How to Check the Cam Lobe

The correct way to check the cam lobe is as follows.

Prepare an outer micrometer that matches the size of your car's cam lobe.
Before you use the outer micrometer, make sure to set it to zero "0".
Next, you need to measure the height of the cam lobe.
After you know the results of the cam lobe measurement, you need to compare those results with the standard specification values of your car. If the measurement value is below the minimum limit of the standard specification values of the car, then the camshaft needs to be replaced. When replacing the camshaft, make sure to replace it with an original product to avoid quick wear.

Thus, the method for checking the camshaft run out that you can follow. How easy is it, right?

If the run out value of your Daihatsu car's camshaft exceeds the maximum limit of your car's standard specification values, immediately replace the camshaft. If you are not confident in replacing the camshaft yourself, you can have the camshaft replaced by visiting a professional workshop like Daihatsu.

Why go to an official Daihatsu workshop? Because this workshop provides competent mechanics, capable and modern service equipment, and sells official spare parts just like Daihatsu's workshop.
