A wear assembly of an earth-moving machine's bucket comprises a male part and a female part both of which comprises a nose (male part) or cavity (female part) with an upper contact surface and a lower contact surface. The upper contact surface comprises an upper front contact portion that extends backward from the tip of the nose or the bottom of the cavity and the lower contact surface comprises a lower front contact portion that extends likewise, one of the upper and lower front contact portions being concave and the other being convex. Analogously, the upper contact surface comprises an upper back contact portion that extends forward from the base of the nose or the mouth of the cavity, and the lower contact surface comprises a lower back contact portion that extends likewise, one of the upper and lower back contact portions being concave and the other being convex.

A ground engaging tooth for a ground engaging machine is disclosed. The ground engaging tooth may comprise a non-ground-engaging end, a ground-engaging end, a body extending between the non-ground-engaging end, the ground-engaging end, a top surface, a bottom surface, a left surface and a right surface. Further, the ground engaging tooth may comprise a coupling side including a pocket configured to receive a retaining device. Moreover, the ground engaging tooth may comprise a wear side including an integral-wear-insert. The integral-wear-insert may longitudinally extend along the bottom surface towards the ground-engaging end and vertically extend towards the top surface at the ground-engaging end.

A rolled lip in which the form of attachment of the noses to the lip prevents the area of attachment to reach a maximum stress, thus reducing the risk of fractures in said area of attachment facilitating machining of the nose in which the lip has grooves projecting from the edge into the lip body; the noses have an area which forms a protrusion in which said protrusion is located in the rear half of the nose on the opposite side of the front; the attachment of the protrusion to the lip is welded all around it and forms one or two channels forming a weld filler area; the shape, quantity and distribution of the channels may vary independently using a channel on the lip or a channel under the lip or a channel on the lip and another under the lip simultaneously; the weld filler area may be above and/or below the lip; the protrusions of the noses fit in the grooves of the lip.

A female part, a retaining device and a pin system have the device, the female part and a male part, to assure the retention between the female part and a male part used in excavators and the like. The female part has a cavity and can be a wearing element, a tooth or an intermediate part (part between a point and a weld on or cast nose in a three part system) and the male part has a nose to be introduced into the cavity of the female part and this will usually be a tooth-holder, intermediate, cast nose, weld-on nose or an adapter.

A wear member for an earth-working implement including a body having front, rear, top, bottom, inner side and outer side portions. The wear member includes a front face defined on the front portion with a front cutout surface, a front lower surface, and a front upper surface. The wear member includes a rear face on the rear portion facing away from the front face. The wear member includes a front cutout on the front face defining the front cutout surface between the front lower surface and the front upper surface. The front cutout surface extends between the inner side portion and the outer side portion and offset from the front upper surface and the front lower surface toward the rear face. The front lower surface and the front upper surface are co-planar and parallel to the front cutout surface and the rear face.

A wear member for an earth-working implement including a body having front, rear, top, bottom, inner side and outer side portions. The wear member includes a front bottom edge, a front top edge, a front inner side edge, and a front outer side edge. The wear member includes a front face on the front portion between the front inner side edge, the front outer side edge, the front top edge, and the front bottom edge. The wear member includes a front lower cutout edge and a front cutout. The wear member includes a front lower surface and includes a front cutout surface defined by the front cutout between the front lower cutout edge and the front top edge. The body is configured to be mounted to a mounting edge of the earth-working implement such that the front face faces a direction away from the earth-working implement.

Extraction tongs with replaceable jaw tips include jaw tips with mating gripping projections. Each extraction tong includes a plurality of inward extending teeth. A thickness of the extraction tong is reduced at a bottom to form a jaw tip extension. A substantially triangular projection extends outward from opposing sides of the jaw tip extension. A plurality of holes are formed through the jaw tip extension. Each jaw tip includes a tong slot, which is sized to receive the thickness of the jaw tip extension. A substantially triangular slot is formed in opposing walls of the tong slot to receive the two substantially triangular projections. A plurality of counterbore holes are formed in opposing sides of the jaw tip. A first lengthwise projection is formed on a gripping surface of the first jaw tip. A pair of second lengthwise projections are formed on a gripping surface of the second jaw tip.

A holder block assembly for a drum-type cutting tool has a holder block and a sleeve that is removably held in the holder block to carry a cutter bit. The sleeve includes a shank received in a hole in a cutter block and a nut threaded on the shank. The nut is turned by a hand tool to extract the sleeve from the holder block.

An adapter includes a first leg, a second leg, and a throat portion that define a slot defining a direction of assembly onto a work implement assembly, a lateral direction that is perpendicular to the direction of assembly, and a vertical direction that is perpendicular to the direction of assembly and the lateral direction. The throat portion further includes a first throat side surface disposed along the lateral direction and a second throat side surface disposed on the opposite side of the throat portion along the lateral direction. The first throat side surface defines a first adapter cover receiving recess.

A ground engaging tool assembly includes a ground engaging tip, an adapter, and a wear cap. The ground engaging tip has a ground engaging portion and a coupling portion including an interior surface defining a coupler pocket with an adapter opening and first and second lug openings. The adapter includes a mounting nose with first and second retention lugs extending from sides of the mounting nose along oblique taper angles. The mounting nose is disposed within the coupler pocket of the ground engaging tip with the first and second retention lugs extending into the first and second lug openings, respectively. The base includes a shoulder surface and a retention surface that define a mounting groove therebetween. The wear cap includes a mounting rail that is disposed within the mounting groove of the adapter to mount the wear cap thereto.
