501X belt tensioner
Just fix in the 3 adjustable belt tensioner and felt that there's a 'click click' feeling when I rotate the spur gear without motor being mounted. Should I adjust the belt bearings touching the belts or leave a 0.5mm gap? Also, the adjustable tensioners are so difficult to adjust especially the bottom one. Any suggestion and ideas? The bottom bearing is very tight with the belt and pulley as the set screw is going clockwise thus rotating the tensioner towards the belt. is it the normal?
