The arrangement is applied to a compressor which comprises: a crankcase (40), carrying a cylinder (41) provided with a lateral slot (42) and in which is housed a piston (10) provided with two radial holes (11) and with an eccentric axial hole (12); a connecting rod (20) connected to a crankshaft (30) driven by an electric motor (50) and having a smaller eye (21) mounted in the piston (10); and a wrist pin (60) having a first end (61) turned to the bearing hub (43) of the crankcase (40), a second end (62) turned to the lateral slot (42) of the cylinder (41) and a diametrical hole (63), adjacent to the second end (62) in which is provided an engaging means (64), for the axial and rotational coupling of a tool (80) for mounting and indexing the wrist pin (60), in the interior of the piston (10), in a position in which the diametrical hole (63) is axially aligned with the eccentric axial hole (12), so as to allow an elastic pin (70) to be introduced in said diametrical hole (63) and in said eccentric axial hole (70). |
