Measuring the rubber track is relatively simple if you know what to look for. Below you have our simplified guide that will allow you to identify the size of the track you have installed on your machinery. All you need is a measuring tape or a ruler. For our example we have selected a wide gauge 300x52,5x78 track.
STEP 1
Measuring the width
Place the measuring tape across the top of the track (as in the photo) and note the size. This measurement is always shown in mm (in our case 300mm).
STEP 2
Measuring the pitch
This is measured from the centre of one lug to the centre of the next lug (as in the photo). This measurement is always shown in mm (in our case 52,5mm).
STEP 3
Counting the links
These are measured on the inside of the track. Mark one link and then count each link around the total circumference of the track until returning back to the marked link (in our example, 78 links, 6 links shown in the photo).
STEP 4
Measuring the gauge
Measure between the lugs from the inside of one lug to the inside of the lug opposite. This measurement is always shown in mm (in our case 46mm, corresponding to a wide gauge track).
IMPORTANT - step 4 is only required for 300mm/ 350mm/ 400mm and 450mm wide tracks.
STEP 5
Checking the type of roller fitted
This step is only required on some 300mm and 400mm wide tracks, which can have an inner rail type roller style fitted (roller on the right) or an outer rail type roller style (roller on the left).
STEP 6
Look for any markings
If you are having trouble measuring the track, then you can look for any markings that will help you to identify the size. Most rubber tracks have the size stamped into the rubber. This is usually found on the inside of the track. The numbers represent the width (300) x the pitch (52,5), the gauge (W) x the number of links (78).
