ABSTRACT:
An upper end portion of an excavation ripper shank is captively and removably retained in a ripper box using a specially designed flex pin connector longitudinally driven into generally aligned openings in the ripper box and shank. The connector includes first and second rigid pin members held in a spaced apart, parallel, laterally facing relationship by a plurality of elastomeric members bonded to facing side surfaces of the pin members. When the connector is driven into the aligned box and shank openings the elastomeric members are compressed, causing the first and second pin members to drive the shank and box into forcible abutment with one another to substantially eliminate relative side-to-side play therebetween. Additionally, as the connector passes through the first and second openings its first and second pin members are caused to pivot relative to one another about an axis parallel to the compression direction of the elastomeric members. When the connector reaches its installed position the first and second pin members return to their original pivotal orientation, and locking projections on their end portions releasably block longitudinal removal of the flex pin connector. A second connector, substantially identical to the first connector, is removably received in an additional opening formed in the ripper box and has outer side portions that resiliently bear against the received ripper shank portion and an interior side surface portion of the additional ripper box opening that faces such ripper shank portion.
