How to Adjust a Go Kart Torque Converter
Adjusting the torque converter on your go-kart is a relatively simple process, but it must be done with care and precision.
Follow these steps to ensure that your torque converter is properly adjusted:
Remove the Nut, Cam, Snap Ring, and Spring
You will now have access to the spring, which you must modify. How to do it:
The snap ring and nut that are fastened to the fixed cam must first be removed. After removing the snap ring and nut, you can now proceed to remove the torque converter’s fixed cam and spring.
Leave everything else in its current state. That way, you may replace the torque converter without removing the chain or belt.
Adjust the Spring
You need to get access to the spring to modify your torque converter. The most difficult part will be removing the snap ring and the nut attached to the fixed cam.
After removing those, remove the fixed cam and spring from the torque converter. To increase preload, wind the spring clockwise until it is tight.
If you need to decrease preload, wind the spring counterclockwise. The amount of preload will determine how much power is transferred from the engine to the wheels.
Reassemble the Snap Ring, Nut, Cam, and Spring
After adjusting the spring to the desired preload, you can reassemble the component parts. The snap ring needs to be replaced first.
After that, you have to screw the nut on tight. There needs to be a reinstallation of the camera.
Preload the Spring and Assemble the Snap Ring and Nut
Now it’s time to preload the spring. First, put the snap ring through the hole in the torque converter body.
Next, take the flat end of a screwdriver and push down on the snap ring while you turn the nut clockwise. As you turn the nut, the snap ring will be pulled up and preloaded against the boss of the torque converter body.
Stop turning the nut when there is a gap of about 0.38 inches (or one centimeter) between the bottom of the torque converter body and the top of the snap ring. At this point, the snap ring is preloaded, and you may now continue to tighten the nut until it is snug.
How to Identify if Your Torque Converter Needs Adjusting
If your go-kart is experiencing any of the following symptoms, it’s a good indication that your torque converter needs to be adjusted:
The Engine Revs Up, but the Go-Kart Doesn’t Move
If your engine is revving up, but your go-kart isn’t moving, this is a sure sign that something is wrong with your torque converter. In this situation, it’s likely that the spring inside the torque converter has come loose and needs to be adjusted.
The Go-Kart Moves Forward Even When You Let Off the Gas
This is another symptom that points to an issue with the torque converter. If your go-kart moves forward even when you let off the gas, it means that the spring inside the torque converter is too tight and needs to be loosened.
The Go-Kart Doesn’t Move Forward Even When You Step on the Gas
Conversely, if your go-kart isn’t moving forward even when you step on the gas, it’s an indication that the spring inside the torque converter is too loose and needs to be tightened.
The Go-Kart Moves Forward but Then Stops Abruptly
If your go-kart moves forward but then stops abruptly, it’s a sign that the spring inside the torque converter is too loose.
In this case, you’ll need to tighten the spring.
The Go-Kart Jerks Forward or Stalls
If your go-kart jerks forward or stalls, it’s an indication that the spring inside the torque converter is too tight. You’ll need to loosen the spring in this case.
Factors that Affect Go-Kart Torque Converter Adjustment
Adjusting the torque converter in your go-kart may be complicated by a few different circumstances. Some of these are:
The Type of Engine You Have
Go-karts can be powered by a variety of motors, including two-stroke and four-stroke designs. Torque requirements for wheel rotation vary depending on the type of engine you have.
The Weight of the Go-Kart
The torque needed to spin the go-wheels karts is also affected by the vehicle’s mass. Torque is essential for go-karts of varying weights, with higher values needed for heavier vehicles.
The Type of Tires You Have
The amount of torque needed to spin the wheels of a go-kart might vary depending on the tires installed on the vehicle. More force is needed to turn softer tires than harder ones.
Off-road go-karts are distinguished from their street-legal counterparts by their more rugged tires.
The Surface You’re Driving On
The surface you’re driving on will also affect the amount of torque that is required to turn the wheels. Softer surfaces will require more torque than harder ones.
The roughness of the surface will also affect the amount of torque that is required. Rougher surfaces will require more torque than smoother ones.

Final Thoughts
Adjusting a go-kart torque converter is not difficult, but there are a few things you need to keep in mind. Make sure to preload the spring and then assemble the snap ring and nut.
Also, be aware of the signs that your torque converter needs adjusting, such as revving up but not moving, moving forward even when you let off the gas, or not moving forward even when you step on the gas.
