Help needed with torque convertor.

[Dimav09]

Hello everyone,

I just installed a torque converter on a Manco Interceptor and its a huge improvement in speed, torque, and fun. When I accelerate or take off everything runs great, top speed is completely smooth but when I left off the gas there is a horrible vibration. When I hit the gas again the vibration stops. If I'm braking the vibration is even worse. Do you have any idea what's going on. This is a Amazon Chinese 30 series torque convertor running on a 6Hp Subaru Robin engine. I never had vibration issues running this kart with a clutch so the issue has to be coming from the torque convertor.

From your other post your belt alignment looks good but the bolt holding on the drive clutch looks downright scary. I've never had one do what you are describing and I have 6 vehicles with torque converters. The Amazon and
E-bay units are the same as all the torque converters. They are all made in China. Go spend $1.50 on a grade 8 bolt of the correct length ( probably 2 1/2
inches ) , put some blue lock tight and torque it to 24 lb ft and see if that helps.
at the very least it won't fly off.

One other thing. Do you still have the Chineseum belt on the kart that the kit came with? If yes take the belt off and go climb Mount Everest and when you get to the top throw it off.
No, don’t do that it’s littering and against the law. But do take it off and throw it away properly. Then get the proper Genuine Comet belt to replace it. You also might want to get some spray on dry graphite and lube up the primary and secondary clutches. Also follow Pancho’s directions. He knows of which he speaks!
