I hope I don't sound here like I pretend to know something about this, because - quite frankly - I don't. However this is what I know: * too loose and the belt will whip, too tight and it will whine * I have broken pretty good size journal, because I was tightening the belt drive by ear. There was really little difference between "pretty good" and "even better". This even better worked for three years and then shaft bore next to cogged wheel..... * One company recommeds hand thightening it and then further tightening of 0.4% of wheelbase. I.e 4mm per every metre of the centre of the shafts. This is on pretty high spec linear drive....rotary ones we use Trummeter. I found this one, where is some info on pages 22 on, but if you don't have this info then it is only mildly interesting..... http://www.mulco.net/content/en/download/res/34298-1.pdf PekkaNF |
