FLANGED MASTER TRACK PIN WITH RETAINING RING

Abstract:

A master link box for use with a link assembly of a work machine is disclosed. The master link box may include first and second master links with pin bores and lateral annular recesses disposed around the pin bores, a master link pin with a radial projection at a proximal end and a distal annular groove in the outer circumferential surface near the distal end, and a master retaining ring. The master link pin may be inserted through either master link until the radial projection of the master link pin abuts the lateral recess of one of the master links. The master retaining ring may be secured in the distal annular groove to prevent the master link pin from retracting through the master link box. The master retaining ring may be secured in the distal annular groove without press-fitting the master retaining ring.
