In general, a spring pin is a cylindrical pin with a spring feature that holds it in position or allows it to be retained by a mating part. Its exact role in any assembly must be checked against the catalog entry and the machine documentation.
Use part number 0273873 when ordering. Before ordering, check the recorded catalog associations and their listed serial number and configuration conditions against your machine, since a listing does not establish compatibility for every configuration.
