Abstract

In the method, a joint pin (10) is fastened in a removable manner to a first structural member (100), such as a shovel or the supporting part of a shovel in loading, mucking or excavating equipment. The structural member is provided with a conical recess (102) and a threaded fastening hole (104) at the bottom of the recess. The joint pin is provided with a conical fixing piece (14) that matches the recess, and a hole (12) extending in the direction of the longitudinal axis of the joint pin. The fixing piece is fitted in the recess of the first structural member and is fastened in its place by a fastening screw (20), wherein the fixing piece is pressed tightly into the recess. The joint pin is provided with a pin part encircled by an annular bearing (30) placed in a bearing hole (202) in a second structural member (200). The hole of the joint pin has an inner threading for engaging an extraction tool. The largest diameter of the fastening part is larger than the diameter of the pin part, wherein the joint pin to be extracted will remove the bearing (30) fitted around the pin part from the bearing hole (202).
