Two maintenance employees were working together replacing a shaft pin, bushings, and spacers on a crimping machine. While they were attempting to lower the top half via a crane into the bottom half, the parts became misaligned. The first employee used his finger to feel inside the shaft hole and determine why it was not fitting together. The second employee, who was at the controls of the hoist, lifted the part, causing the very tip of the first employee's left index finger to become caught. The first employee suffered a fingertip amputation to the index finger on his left hand.
