A system for disassembling a drive pinion assembly of a starter motor is disclosed. The drive pinion assembly includes a drive gear and a pinion member coupled to the drive gear through a mounting hole defined in the drive gear. The system includes a base member for supporting the drive pinion assembly. The base member includes a through hole to align with the mounting hole of the drive gear. The system further includes a pin member slidably received in the through hole and an actuating member disposed around the base member. The actuating member is rotatable about a rotational axis defined by the base member. The actuating member includes a cam lobe for moving the pin member towards the mounting hole of the drive gear based on movement of the actuating member about the rotational axis to disassemble the pinion member from the drive gear.

1. A system for disassembling a drive pinion assembly of a starter motor, the drive pinion assembly comprising a drive gear and a pinion member coupled to the drive gear through a mounting hole defined in the drive gear, the system comprising: a base member configured to support the drive pinion assembly therein, the base member comprising a through hole configured to align with the mounting hole of the drive gear;a pin member configured to be slidably received in the through hole; andan actuating member disposed around the base member and rotatable about a rotational axis defined by the base member, the actuating member comprising a cam lobe configured to move the pin member towards the mounting hole of the drive gear based on movement of the actuating member about the rotational axis to disassemble the pinion member from the drive gear. 2. The system of claim 1, wherein the base member comprises: a hollow space defined within a first end thereof to receive the drive pinion assembly therein; anda support member coupled adjacent to a second end thereof for detachably supporting the base member on a work surface. 3. The system of claim 2, wherein the support member comprises an opening in communication with the hollow space of the base member to receive the pinion member to be disassembled from the drive gear. 4. The system of claim 2, wherein the actuating member comprises: a first member rotatably disposed on the support member; anda second member disposed on the first member, the second member comprising the cam lobe defined at an inner surface thereof to engage with the pin member;wherein the first and second members are configured to rotate about the rotational axis. 5. The system of claim 4 further comprising a third member coupled with the first and second members, wherein the first, second and third members are configured to rotate about the rotational axis. 6. The system of claim 1, wherein the pin member comprises a head portion and a shank portion extending from the head portion, the shank portion slidably received within the through hole. 7. The system of claim 6, wherein the cam lobe is configured to engage the head portion of the pin member to move the pin member along a lateral axis defined together by the through hole of the base member and the mounting hole of the drive gear to disassemble the pinion member from the drive gear. 8. The system of claim 1, wherein the pin member is resiliently disposed within the through hole via an elastic member. 9. The system of claim 1, wherein the cam lobe defines a lobe lift greater than or equal to a length of the mounting hole of the drive gear. 10. The system of claim 4 comprising a handle coupled to the actuating member to receive an input from an operator and to rotate the actuating member about the rotational axis. 11. The system of claim 10, wherein the handle comprises: a first handle member coupled to the first member of the actuating member; anda second handle member coupled to the first handle member, and configured to receive the input from the operator. 12. A method of disassembling a drive pinion assembly of a starter motor, the drive pinion assembly comprising a drive gear and a pinion member coupled to the drive gear through a mounting hole defined in the drive gear, the method comprising: supporting the drive pinion assembly on a base member, wherein an actuating member having a cam lobe is positioned around the base member;aligning the mounting hole of the drive gear with a through hole defined in the base member, the through hole having a pin member disposed therein;rotating the actuating member about a rotational axis defined by the base member, wherein the cam lobe moves the pin member towards the mounting hole to disassemble the pinion member from the drive gear. 13. The method of claim 12 further comprising supporting the base member, via a support member, on a work surface. 14. The method of claim 12, wherein the pin member comprises a head portion and a shank portion extending from the head portion, wherein the shank portion of the pin member is disposed within the through hole. 15. The method of claim 12, wherein the actuating member comprises: a first member rotatably disposed on the support member; anda second member disposed on the first member, the second member comprising the cam lobe defined at an inner surface thereof to engage with the pin member. 16. The method of claim 15, wherein the actuating member further comprises coupling the first and second members with a third member via fastening members. 17. The method of claim 12 further comprising moving the actuating member, via a handle, about the rotational axis. 18. The method of claim 12, wherein the cam lobe defines a lobe lift greater than or equal to a length of the mounting hole of the drive gear. 19. A system for disassembling a drive pinion assembly of a starter motor, the drive pinion assembly comprising a drive gear and a pinion member coupled to the drive gear through a mounting hole defined in the drive gear, the system comprising: a base member configured to support the drive pinion assembly therein, the base member comprising a through hole configured to align with the mounting hole of the drive gear;a pin member having a head portion and a shank portion extending from the head portion, the shank portion slidably received within the through hole; andan actuating member disposed around the base member and rotatable about a rotational axis defined by the base member, the actuating member comprising: a first member rotatably disposed around the base member; anda second member disposed on the first member, the second member comprising a cam lobe defined at an inner surface thereof to engage with the head portion of the pin member, wherein rotation of the actuating member causes rotation of the cam lobe to move the pin member toward the mounting hole of the drive gear to disassemble the pinion member from the drive gear; anda handle coupled to the actuating member to receive an input from an operator and to move the actuating member about the rotational axis. 20. The system of claim 19, wherein the cam lobe defines a lobe lift greater than or equal to a length of the mounting hole of the drive gear.
