Abstract

The present invention provides for an assembly for locking a tooth or a lip shroud to an adaptor or bucket lip. The tooth or lip shroud has a slot in its lower surface of the end opposite to the point and a first opening in its upper surface extending into the slot.
The adaptor or bucket lip has a boss on its upper surface corresponding to the slot in the tooth or shroud so that when the tooth or shroud is slid onto the adaptor or bucket lip, the slot engages the boss. The assembly includes a pin and a pin carrier. The pin carrier is slidably receivable into the slot in the tooth or shroud. It has an opening for receiving the pin on its upper surface which aligns with the first opening in the tooth or shroud when the pin carrier is inserted into the slot.
The pin is inserted into the pin receiving opening of the tooth or shroud and received into the pin carrier. The pin engages the tooth or shroud and the pin carrier and locks the tooth or shroud onto the adaptor or bucket lip. The pin and pin carrier may also include magnets for holding the pin in position.
