ABSTRACT:
A wedge assembly (10) to cooperate with a wedge element (11) to secure a tooth (12) to the projection (13) of a bucket of an earth-moving machine or ripper. The assembly (10) includes a pair of wedge halves (22, 23) which have external wedge surfaces (24, 25) which converge towards an end (21) of the assembly (10). Located internally of the wedge halves (22, 23) is a wedge member (33) having external converging wedge surfaces (24, 25) which engage converging internal wedge surfaces (30, 31) of the wedge halves. The wedge member (23) has a threaded end (38) which can be engaged by a "puller" to aid in moving the wedge member (33) to release the pressure on the wedge halves (22, 23) to facilitate removal of the wedge assembly (10) from engagement with the wedge element (11).
