The CVT Unit is similar to the other gearboxes from RotaryCraft with the major difference being that the ratio can be set at any number between 0-32. It is identical to a Bedrock Shaft in that it has no speed or torque transmission limits.
The CVT Unit requires 31 belts to be place inside it, along with a bucket of lubricant in order to function (The bucket of lubricant is never used up). After this is done, the CVT is ready for use, and as mentioned above, can be set to any gear ratio between 0 and 32. It can also be set to 2 pre-configured ratios that can be switched between by the use of Redstone. (On is one setting, Off is the other).
