It all began from a great idea of Mechanical Engineering students graduating batch '56. These men had a vision of forming an organization for the mechanical engineering majors to promote camaraderie and unity among the students. It would also serve as a medium for promoting academic excellence.

In 1955, the UP Gears & Pinions was founded. The organization served as a venue for social and co-curricular activities to balance the rigorous and difficult demands of the course.

Through the years, the organization has consistently undertaken projects which have benefited the members, the college and the community. Some of its recent activities and projects include the highlights of ME Days celebration: The Diliman Motorshow where car enthusiasts showcase their automobiles and their skills in car maintenance and upgrading; The Great Cover-UP where different organizations participate in the covering of worn out books from the engineering library; Machine Design Contest which aims to showcase the creativity of engineering students from different universities from all over Metro Manila; Technology Exhibit, Showbiz Bingo, and much more. These projects were initiated to diversify the capabilities beyond ordeals of academics, which proves that the members of the Gears and Pinios are, indeed, well-rounded individuals that will be versatile engineers of the future.
