Hi, I'm a beginner in mechanics so I need some help with a project I started. My project consists of a small kart-like car. The car will be Rear-Wheel-Drive and Rear-Engine too (RR layout). and I am willing to use a small 110cc moped engine. I have a trike Differential Gear for the rear shaft that I want to use. It has a prop shaft drive. I want to change that and convert it into a Chain Drive Differential. Is it possible by adding Sprockets to the ring gear (and opening the differential housing to pass the chain)? can I put the Sprocket outside the housing? or is there a better solution? My aim is to mount the chain directly between the engine and the Differential Gear.
