Do this:
Loosen the coupler and spin the stock shaft by hand and make a mental note on how freely it turns. Then after pulling the liner, try the same thing with the HD shaft.
Side note on HD shaft installing:
The coupler is longer and reduces the space between the coupler collet nut and the brass stuffing tube. Some have had to trim the tube when using a shaft saver collar.
I was able to get it to work by adjusting the motor mount forward and the motor up/down in the mount. Make sure the shaft lines up and slips easily in and out of the coupler with final adjustments.
