The wheel position defines the required profile

Record the tooth in place

A detached tooth shows its body shape. A photograph on the cutter wheel also shows its orientation, holder, neighbouring teeth and the direction in which the cutting edge is presented. Keep both views when comparing a replacement.

Compare wear by position

Keep the wheel position with each inspection photograph. Edge chipping, loss of carbide, body erosion and seat movement are different observations. Comparing them by location is more useful than combining all removed teeth into a single wear judgement.

OEM fit is not specified for these models. Match the tooth to the actual cutter-wheel and holder drawing.
