"An inspection device with proximity switch monitoring should visibly indicate to the operator if one or two circlips are missing. When driving up, an inspection pin should not damage the piston pin bore in the piston. The application of finished Drylin® linear housings and iglidur® G bearings enable a clean and easy drive up of the centering pin. The excellent guidance additionally prevents the damaging of the piston pin bore. ”
