The basic PK Belt drive consists of a driver on the engine and a driven on the drive wheel or axle. The belt is tensioned either by moving the engine forward or by pushing a belt tensioner on the belt.

The belt tensioner system requires some durable tensioner pulleys. Those too can be purchased at a local hardware store. The belt tensioner is basically a pulley that is jammed into the face of the belt causing the belt clearance between the engine driver and the wheel pulley to lessen. This now tensioned belt grabs much better and causes the wheels to turn.

This is an important note about belt clutch systems. Always make the system deactivate by itself when no human input is being done. For example, the foot releases the pedal, the clutch automatically releases. The reason for this is if the engine is being started, the last thing you want is for it to be in gear. This will cause the go kart to lurch forward during start up. Again, it is important to have the clutch system deactivate automatically.

The tension side will always be tight, but the tensioner on the slack side encourages full belt wrap; and that is the key to the belt drive: at least 180 degrees or more of belt wrap around the engine pulley.

It is important to be on the slack side of the PK Belt when using a tensioner; otherwise you will be fighting the engine and constantly burning up belts. The way to look at a belt is to view it as a glorified rubber band. The belt stretches as it passes the engine pulley.
