DIY Go Kart Transmission

Acting as your kart’s automatic transmission is its torque converter, which being a type of hydraulic coupling, will let the spin of the engine happen separate from that of the transmission itself. In order to even approach building your own go-kart transmission you need to have a good comprehension of how engines work. At the times when the run on the engine is slow, say when it is avoiding going in a ditch, passing through the torque converter is only a little amount of torque. That way only so much effort is needed on the break pedal to keep from that ditch. If the go-kart is stationary and you have the gas pedal pressed down, you need more effort on the brakes to stop the wheels’ motion. This is because when the gas pedal is being stepped on the engine then gets faster and more fluid gets pumped into the torque converter. This means more torque gets to the wheels.

How Torque Converter Work

Once you understand the basic principles of torque converters and how they work you can get to building your own using re-cycled materials from things like old washing machines. So if you understand the above or already have knowledge of transmissions and how they work here is a four step guide to building your own go-kart transmission, using materials you have already recycled from elsewhere.

Step One – Bolting the converter housing

To the go-kart engine you need to bolt the housing for the torque converter. This is where whatever speed the engine is doing the turning of the torque occurs here.

Step Two – Put on the fins

You can see the pump that is fixed in the torque converter as like a centrifugal pump. As it turns the fluid is flung to the outer sections also much like a washing machine’s spin cycle. This action creates a vacuum that then pulls more fluid to the center which again gets flung to the sides and so on.

Step Three – Turbine connection

Once the fins are attached you need to connect together the turbine and the transmission. This will allow the fluid to enter the turbine’s blades and make it spin, and that will get you go-kart moving.

Step Four – Stator at the center

To the absolute center of the converter you should bolt the stator. This is an important step in building your own go-kart transmission as it takes the fluid that returns from the turbine and redirects it before it gets to the pump. This is how you keep the torque converter working efficiently. The stator has a vital feature in that its blade design is very aggressive and effective at driving the fluid backwards. Inside it is a one way clutch that then connects the stator to the transmission via a shaft inside it.
