Ndn. Yes that is a very popular torque converter. If you don't have any luck in your efforts to refurbish it, you can order a new one. Amazon probably has 10 different brands for sale. They are all from China and they all work very well. There isn't a bit of difference between brand A, B, or C. It is a 30 series torque converter. They are priced from about $60 to $70. You get everything in the kit.
The mounting plate that bolts to the engine, the drive clutch that goes on the crankshaft, the driven clutch, the shaft it rides on, two small sprockets for either pitch of chain, a belt guard and a cheap Chinese belt. It will eventually break and when that does happen you want to replace it with a Comet brand belt. It will outlast 4 or 5 of the cheaper belts. I own 3 big two seater karts and one mini bike equipped with units as described above and they work great.
Important: Verify that the crank on your engine is 3/4"
