PROJECT :- 1 PROJECT OBJECTIVE: TO DESIGN A TOOL, TO DISASSEMBLE THE DRIVE SHAFT FROM THE 540 RPM PTO GEAR BOX. PROJECT DETAILS: basically swaraj produces two types of gear boxes for the tractors in this plant. The first one produces 1000 rpm at PTO shaft as a standard value and the other one produces 540 rpm at PTO shaft. The tractors use sliding mesh type of gearbox. The gear box consists of 8+2 gears. But to produce the higher torque at lower rpm, the 540 rpm PTO type gearbox uses an additional drive shaft, which is fitted inside by the manual hammering. But once it gets fitted inside the gearbox, it is difficult to remove it by any proper method. In case of a faulty gearbox, it is very complex to remove the drive shaft. And since it is mounted on the input shaft of the gearbox, the whole gearbox cannot be disassembled without taking it out of the gearbox. Since the start of the production of 540 rpm gearbox, the issue of removing the drive shaft is a headache in order to disassemble the gearbox. Still they remove
