ADJUSTABLE SHIMABLE INDEXABLE SHEAR TIP
An adjustable shimable indexable shear tip for a distal end tang of a heavy duty demolition shear having a upper movable shear jaw with a shear side and a guide side pivotally connected to a lower shear jaw with a shear blade side, a guide side, a distal tie plate and a recess therebetween. The tang has side faces with apertures therethrough, a top seat, a rear seat and a bottom seat. The adjustable shimable shear tip has a two-sided shear tip section with a sidewall and a bottom wall that is adapted to be seated on one of the side tang faces, the top seat, the rear seat and the bottom seat. The bottom wall is formed with the sidewall at a shear edge and is adapted to be seated on the tang bottom seat with a leading shear punching edge. A side plate is adapted to be seated on the other tang side face, the top seat, the rear seat with another shear edge along the bottom wall. The side plate has apertures therethrough alignable with the sidewall apertures and the tang apertures to secure the sidewall, lower wall and access plate to the tang. A shim or shims with matching apertures to the sidewall and the side plate are adapted to be insertable inside the sidewall and the side plate against the tang faces either after the faces have become worn or otherwise if the shear tip needs dimensional adjustments to fit the tang. An extending boss maybe on the lower inside face of the side plate as to index and interlock with a matching indexing slot on the distal face of the bottom wall.
