A cluster shaft is a rotating member/machine element, which is used to transmit power from one place to another. A cluster shaft is a shaft that runs parallel to the main shaft in a gearbox, and carries the pinion wheels. The failure of the second gear mounted on the cluster shaft occurred due to wear and tear. The objectives of the paper is to study the existing cluster gear shaft, and providing the proper solution so as to avoid the failure of cluster gear shaft. There are various reasons due to the gear may fail, few of them could be application error, design error, manufacturing error or application error. According to American gear manufacturing association, the failures of gear can be classified into four major categories namely surface fatigue, wear, plastic, and breakage. It has been observed that in most of the cases the failure starts from the bearing. After FEM analysis it is found that the maximum equivalent stress occurred on the second gear which is equal to 12.45 MPa. Keywords: gear failure, wear, lubrication, misalignment.
