## Narrative

Employees were assigned to change out a bad gearbox on the drive end of the 208-01-2 filter. The gearbox wouldn't move with the hammer. They used a ram hydraulic puller. One of the puller fingers sheared off the gearbox sending the puller fingers flying into the left shin of one of the workers. The employee was lacerated by the puller and was transported to the hospital.
