I added a torque converter to my coleman ct200u and the shaft sizes are different so this converter was needed. It worked exactly as described.

This is a nice Trapped Key design. Great for some applications, however it will not work with drivers that have a built in key or use a fixed extended key. This sleeve would be nice for a Pulley, Pressure washer pump or some device that uses a separate key. The sleeve and key fit the 3/4" shaft well, and it is made out of durable materials. All of my clutch drivers has been engineered with the integrated key, across the full length of the Clutch Hub, this version left me high and dry. I probably could have opened the ends of the adapter sleeve in a pinch, that wasn't necessary as I had time on this project so I ordered the correct adapter with the full length keyway.

This piece was not true to size and did not fit. The part required. Even after extensive research and sizing. I would not recommend or order again.
