Knowing the main components of a rubber track is crucial when measuring it for replacement. The rubber track consists of several key parts, including the track itself, the lugs, the pitch, and the guide system. Each of these elements plays an important role in how the track fits and performs on your machine. If any of these measurements are off, it can lead to poor track performance, uneven wear, and potential damage to the undercarriage. Understanding the components helps ensure that you get an accurate measurement that will maintain the functionality and longevity of your equipment.
The width is the simplest of the measurements needed to replace a rubber track. This refers to the overall distance across the track. To measure, place the tape measure across the track at its widest point. It's essential to measure in a straight line and avoid areas with dirt, debris, or wear. If you prefer working in inches, remember that 1 inch equals 25.4 millimeters, so always convert correctly when necessary.
A small error in width measurement can cause stress on the undercarriage, leading to track misalignment and excessive wear. It's essential to double-check the measurement to ensure that it's accurate before ordering your replacement rubber track.
The pitch refers to the distance between the center of one drive lug to the next. This measurement is important for ensuring that the sprockets engage correctly with the rubber track. Incorrect pitch measurement can cause skipping, slipping, or uneven track wear.
To measure the pitch, place your tape measure at the center of one drive lug and measure to the center of the next. It's important to take several measurements across the track, as uneven wear can sometimes cause the pitch to vary across different points.
Repeat the measurement in several places along the track to ensure consistency. Incorrect pitch can lead to costly downtime and further damage if not measured accurately.
The links are the individual segments that connect to the sprocket and allow the track to move smoothly. Counting the number of links is an essential part of ensuring the track fits correctly.
To count the links, check the inner circumference of the track and count each lug carefully. A mistake here can lead to misalignment, which may affect the performance and lifespan of the track. Ensure that you count every lug, and don't forget to check for any missing or damaged links. Missing or damaged lugs should be replaced, as they will prevent the track from moving properly.
Once you've measured the pitch and counted the number of links, you can calculate the inner circumference of the rubber track. The formula for this calculation is:
Inner Circumference = Pitch (mm) × Number of Links
For example, if the pitch is 86 mm and there are 55 links, the inner circumference would be:
86 mm × 55 links = 4,730 mm inner circumference.
Calculating the inner circumference helps to confirm your measurements before purchasing the replacement track. This step is crucial for ensuring that the track will fit properly on your machine and that all of your other measurements are accurate.
The guide system of the rubber track helps to maintain its alignment and ensures that the track moves smoothly over the rollers. There are two primary types of guide systems: the Outside Guide (OG) and the Inside Guide (IG). Knowing which type of guide system your machine uses is essential for choosing the correct replacement track.
Outside Guide (OG): The rollers run along the outer edges of the track.
Inside Guide (IG): The rollers run between the pairs of links.
Understanding the type of guide system in your machine helps prevent purchasing the wrong track, which can result in misalignment and unnecessary wear on both the track and the undercarriage.
Once you know the type of guide system, you can proceed to measure the bottom of the guides.For OG systems, measure the distance between the outer bottoms of two opposing links. For IG systems, measure the distance between the inner bottoms of two opposing links. Even if two tracks have the same width and pitch, if the guide system is mismatched, the track will fail to fit properly, potentially causing derailment or uneven wear.
The guide height ensures the track stays properly aligned during operation.
OH (Outside Height): This is the distance from the outside trough to the bottom of the lug for OG systems.
IH (Inside Height): This is the distance from the inside trough to the bottom of the lug for IG systems.
Correct guide height is important to maintain smooth rolling and avoid track derailment, which could lead to costly repairs or extended downtime.
The rollers are the components that make contact with the track and are essential for the smooth movement of the track. Identifying the correct roller type for your machine is critical to ensuring proper operation. There are two main types of rollers:
Center Rollers: These rollers run between the track links and are commonly found on IG systems.
Flange Rollers: These rollers run along the exterior edges of the track and are common in OG systems.
Additionally, roller subtypes are indicated by letters such as W, X, Y, and Z. These indicate specific roller dimensions, which should be matched with the track's requirements to prevent any damage or wear. Using the wrong roller type can result in poor track performance and potential undercarriage damage.
Once you've measured all the components of the rubber track, you can combine the measurements to identify the correct size. Accurate sizing is important to ensure that the track fits properly and works smoothly with your machine.
Width: The distance across the track.
Pitch: The distance between the center of the lugs.
Link Count: The number of links connecting to the sprocket.
Guide System: Whether it’s an Outside Guide (OG) or Inside Guide (IG).
Roller Type: Center or flange rollers.
If you're replacing a track and want to confirm the size, look for the stamped measurements on the track. The width, pitch, and link count may be stamped on the inside or outside of the rubber track. However, these stamps may become worn over time, so always double-check with your measurements to confirm the size.
If there are no stamps or if you prefer to measure the track yourself, follow the steps outlined:
Measure the width.
Measure the pitch.
Count the links.
Calculate the inner circumference.
Verify the guide system and roller type.
Double-checking all measurements will help ensure you avoid costly mistakes when ordering the new rubber track.
Once you've measured your track and gathered all the details, compare your measurements against the manufacturer's specifications. Ensure that the guide system and roller type match, as even small variations can cause track skipping or undue stress on the undercarriage. Pay attention to the brand, model, and year of the machine, as compatibility is crucial for smooth operation.
To avoid unnecessary repairs and downtime, it's essential to keep track of the condition of your rubber tracks. Here are some signs that it might be time to replace them:
Worn or Damaged Sprockets: Poor engagement with the sprockets often indicates track wear.
Cracks, Drying, and Missing Lugs: Visible cracks or dry, brittle rubber can be a sign that the track needs to be replaced.
Loss of Tension: Over time, tracks can stretch, and while tightening may help temporarily, a replacement is usually the best option.
Timely replacement of rubber tracks is essential for keeping your equipment running smoothly. Regular inspection helps you catch any potential issues early, preventing further damage and costly repairs. By maintaining proper track tension and alignment, you can extend the life of your tracks and your machine.
For accurate measurements, use a tape measure or calipers, pitch gauges for precision, and tools to convert between metric and imperial measurements. Always remove any debris before measuring and ensure that measurements are taken at multiple points for consistency.
Carefully document all your measurements, including width, pitch, link count, guide system, and roller type. This documentation will help streamline the ordering process and reduce the likelihood of errors. Be sure to keep a copy of your measurements for future reference to ensure compatibility when it's time for a replacement.
