One of the key components of an excavator is its tracks, which allow the machine to move around on rough terrain. Steel excavator tracks are the most common type of track used in excavators. These tracks need to be adjusted periodically to ensure optimal performance and to prevent damage to the excavator.
In this blog post, we'll take a closer look at the steps involved in adjusting the length of steel excavator tracks. We'll start by discussing the reasons why track adjustment is necessary, followed by a step-by-step guide on how to adjust the length of steel excavator tracks.
Why Adjusting Excavator Tracks is Important?
There are several reasons why you may need to adjust the length of steel excavator tracks. Here are some of the most common ones:
Worn tracks: Over time, the tracks on an excavator can wear down due to constant use. This can cause the tracks to become loose and affect the machine's stability.
Uneven ground: When working on uneven ground, the tracks can become misaligned, which can cause problems with traction and steering.
Changes in temperature: Changes in temperature can cause the tracks to expand or contract, which can affect their tension and cause problems with the machine's operation.
Now that we've established why track adjustment is important, let's take a closer look at how to adjust the length of steel excavator tracks.
Step-by-Step Guide on How to Adjust the Length of Steel Excavator Tracks
Adjusting the length of steel excavator tracks requires some technical knowledge and experience. However, with the right tools and proper guidance, you can do it yourself. Here are the steps you need to follow:
Step 1: Prepare the Excavator
Before you start adjusting the tracks, you need to prepare the excavator. Make sure the machine is on a level surface and the engine is turned off. Park the excavator on blocks to raise the tracks off the ground. This will make it easier to adjust the tracks.
Step 2: Loosen the Track Adjuster Cylinder
The track adjuster cylinder is a component of the excavator that adjusts the tension on the tracks. You'll need to loosen this cylinder to adjust the tracks. Locate the cylinder and use a wrench to loosen the lock nut. Then, use another wrench to turn the cylinder counterclockwise to release the tension on the track.
Step 3: Remove the Master Pin
The master pin is a component that holds the track together. You'll need to remove this pin to separate the track so you can adjust its length. Use a hammer and a punch to remove the master pin.
Step 4: Adjust the Length of the Track
Once you've removed the master pin, you can adjust the length of the track. Use a measuring tape to measure the distance between the track rollers. This will give you an idea of how much you need to adjust the track. Move the idler wheel and the front idler to the desired position, making sure the track is taut.
Step 5: Reassemble the Track
Once you've adjusted the length of the track, you need to reassemble it. Insert the master pin back into the track and use a hammer and punch to secure it in place. Then, use the wrench to turn the track adjuster cylinder clockwise to tighten the tension on the track.
Step 6: Check the Tension
After reassembling the track, you need to check the tension. Use a tension gauge to measure the tension on the track. The tension should be between 1.5cm to 2 cm. If the tension is too loose or too tight, you'll need to adjust the tension.
