Measuring with an Ultrasonic Tool

• Feel the bush with your hand to find the worst area of wear, whether it be the forward drive side, or the reverse side

• Place the ultrasonic probe on metal surface

• Twist the probe as necessary in order to ensure the good quality of the reading
• Measure the worst side at different points to get the worst point of wear.

Measuring the Bush with a Caliper

• Tighten Callipers to rest at the centre of the bush and the worn surface.

• Measure both forward and reverse wear surfaces

• Use the ruler to measure the callipers tip gap.

Measuring with the Calipers

• Facing the Carrier Roller, place the Calipers at the centre, making sure they are centralised both in height and width.

• Measure the distance between Calliper tips with a ruler
