A chain driven transmission is a simple piece of modern machinery that is designed to be stronger and more resilient to ground conditions that spindle and belt drive systems, but without proper maintenance, even a solid steel chain and gear system will quickly fail.

This guide will not show you how to maintain your specific chain driven transmission, but it will give you guidelines that you should be able to apply to any chain driven mechanism.
