I am having trouble getting the belt to track on my new grinder. I am hoping that the collective wisdom of this forum can help.
I have a 2 x 48 set up with the 8 inch drive wheel attached to a 1.5 hp motor and a 4 inch small contact /tracking wheel attached via separate armature to a flange that in turn is attached to the motor face plate. It's kind of a big cousin to the delta set up that can be bolted on to a hard wheel bench grinder.
The problem is that the belts will not track true and run off to the right of the drive wheel and the contact/tracking wheel. The direction of belt travel is towards the operator and it tracks right, I cannot get it to track all the way to the left or centre it up. At it's best the belt hangs 9 mm over on the drive wheel and 13 mm over the contact wheel.
I've lined both wheels up carefully with a straight edge, but I figure I've still got to sort out either the toe out or the toe in, but I don't know where to start. It seems that the mounting flange may not be square to the spindle that the drive wheel is attached to. Anyway I figure that the flange is really the only thing that I can adjust and probably need to shim it either at the front or the back, but I don't know which or how much.
Any thoughts or suggestions would be really appreciated.
