Monoblock Shoe or Link

Note: in the TrackTreads system, Monoblock shoes are treated and named as links. This is because the TrackTreads system always requires a link to be present and uses the link to track the chains

Track Pad Pass – Depth Gauge 

UT Measurement/Depth Gauge 

1. Place the depth gauge across the top of the rail perpendicular the link rail

2. Push the depth gauge pin down to the mid-point of the pin. 

3. Measure the length of the pin using a ruler 

Track Pad Pass – Ultrasonic Tool 

1. UT Probe must be directly over the mid- point of the pin hole. Ensure probe is clear of dirt and debris. 

Track Pad Grouser Height

1. In order to measure the Grouser height, only use a Depth Gauge.  

2. Clean all dirt from between the grouser area to be measured.  

3. Take into account any metal deformation which can cause readings to differ.  

4. Place the depth gauge across the grousers and push the pin to the bottom to measure the distance x in the diagram below. 

Track Pad Cam A 

1. There is 1 measurement for the Drive lug in position A.  

2. Use a set of Callipers to measure at position B.  

3. Note in the comments, the wear on both the forward drive side of the lug as well as the reverse side of the drive lug. This will give a clear indication of the amount of propelling. 

Track Pad Cam B

1. There is 1 measurement for the Drive lug in position B.  

2. Use a set of Callipers to measure at position B.  

3. Note in the comments, the wear on both the forward drive side of the lug as well as the reverse side of the drive lug. This will give a clear indication of the amount of propelling. 

Track Pitch 

Track Pitch – Single Track Pad

1. This is the most important measurement for determining whether there is pin wear.  

2. The tape measure is the best method of accurately measuring this.  

3. Measure from the middle of the pin, or from the edge of the pin, but just ensure that both the beginning and the end points on the pin measurement point are the same. 

Track Pitch – Four Track Pads

9. This is the most important measurement for determining whether there is pin wear.  

10. When measuring, this can be tricky as the distance over 4 pins can be quite large.  

11. The tape measure is the best method of accurately measuring this.  

12. Measure from the middle of the pin, or from the edge of the pin, but just ensure that both the beginning and the end points on the pin measurement point are the same
