Sprocket

Sprocket Rim – Depth Gauge

1. Use a Depth Guage placed across the ridge in the middle of the Sprocket, between the teeth as shown above.  

2. Extend the pins until the reach the lowest points on the wear surface where link rail runs on the Idler surface. 

3.Then use a tape measure the measure the length of the pins

Sprocket Rim – Tape Measure

1. Use a tape measure to measure the diameter of the Sprocket Rim. 

2. This might be difficult in cases where the Sprocket is in the machine, and hence the Depth Gauge measurement might be easier. 

Sprocket Tooth – A – Caliper

1. Use a Calliper to measure the top dimension (A) of the tooth. 

2. Consider any metal deformation when taking this measurement. 

Sprocket Tooth – B – Caliper

1. Use a Calliper to measure the bottom dimension of the tooth (B).  

2. Consider any metal deformation when taking this measurement.
