Re: Just checking please - is this a tolerance fit? Small question im not a machinist
So does this mean I machine my block out too exactly 57mm and the FK20 comes smaller for a press or tight fit? Or do I machine in a clearance?
I wouldn't consider that a critical dimension, give the bore a bit of clearance. The forces acting on that block are axial. As far as alignment, making that a press fit will cause more grief than it solves. Just my 2 cents and worth all of that.
Anyone who says "It only goes together one way" has no imagination.
