Analysis, Design, Development, Implementation, and Evaluation of a Two-Leg Puller Set

The two-legged puller set can reach various component diameters, so this tool is more flexible and has an innovative application by using an electric, pneumatic impact tool as the driver. This research is a research and development (R&D) study using the ADDIE approach (Analysis, Design, Development, Implementation, and Evaluation). The stages or process of making a 2-leg puller set are preparation, fabrication, assembly, finishing, and testing the function of the puller set on the bearing or pully components and seeing whether the function of the puller set is correct. The design was carried out using Computer Aided Design (CAD) software, and simulations were also carried out. The product is produced by opening the air compressor lever with a pressure ranging from 40-45 psi connected to a hose and impact tool. If it is greater than 45 psi, it will damage the screw bolt threads and will not be centred. If it is lower than 40 psi, the timing is slow and not working.
