The entire “trick” to using a 3 ½ inch ID PVC coupler is getting the seal in straight, and that the coupler has a ridge inside of it to set the pipe insertion depth. You use this ridge by getting a couple of Allen head cap screws (you may need washers depending upon what the cap screw head diameter is) that will sit on that internal ridge when they are screwed into the crank flange. Using three of four cap screws, you use a cross pattern process to tighten the caps screws by hand to gently and correctly pull the seal into position. Not as elegant, or as quick, as the OEM tool; but definitely one Hell of a lot cheaper for a tool you may only use once or twice in your life, and it works.
