Hello
Rohan,
The best thing I can point you to is
HobartCorp. website you will have to become a new member it is free. Once you have become a new member you will want to log into spec sheets, type the model number D300, at the bottom of the page that pops up it will show parts catalog this will give you a blowup of all the gears and how they go together. Putting one of these together is not easy you may need to find some one to help you.
I hope that this helps you in your venture and thank you for using
FixYa.
