ABSTRACT:
A metal demolition shear has a pivotal axle (4) with threading means (34, 35, 48, 42, 90, 92, 104) at opposite ends for adjusting linear positioning of thrust bearings (25, 26, 55, 56, 64) in order to adjust closeness of a pivotal jaw (1) to a stationary cutter jaw (2) of a demolition shear. A bolt-on replaceable cutter tip (14) is positional on a distal end of the pivotal jaw (1) in slidable contact with an adjustable wear surface (17) on a distal side of the stationary cutter jaw (2). Replaceable cutter blades and steady rest surfaces (17) are positional conveniently on the stationary cutter jaw in selective relationship to the bolt-on replaceable cutter tip (14). A steady rest bearing (19, 57) is extendable from the pivotal jaw and adjustably positional in slidable contact with a surface of the stationary cutter jaw. Roller bearings (25, 26, 64) are provided optionally for decreasing friction workload and for increasing use life.
