Hoping that I never have to do this, I nonetheless saved the doc. the 160Hz resonant tone from the plucked belt is much more useful than trying to figure out how to measure 330 - 380Nm tension in the belt! And I did not know about that app, that alone is really going to be fun to use (and annoying to my wife ;-)
Thanks David for the document and the cocktail ice tip. It had given me more ideas. Thanks also to Colin for the tips.?
I sprayed WD40 on the motor bolts and bought a 13mm extension socket and got them loose. I also completely backed out the grub screw. I tried to use a long board to wedge the motor up but I couldn't get it to budge. Any ideas what to do to get the motor to move up???
