ABSTRACT:
A pin removal and placement tool (50) has a body member (52) made of plate steel having a contact surface (52b) and a rear edge (52c). Tool (50) also may have an anvil plate (54) mounted on a striking plate (56), a drive shaft (58), and a handle (70) projecting at a right angle from the body member (52). The striking plate (56) is fixedly mounted to the rear edge (52c) and anvil plate (54) is disposed at a selected angle to the drive shaft (58) to enhance the striking force of drive shaft (58) and to reduce the length of the tool (50) so as to facilitate its insertion between the teeth of buckets, etc. A shoe (62) may be mounted on tool (5) to adjust the clearance between contact surface (52b) and drive shaft (58). The handle (70) may be either removably or fixedly attached to the body member (52) and be dimensioned and mounted to selectively project from a selected side thereof, or from both sides thereof.
