Because it looks very nice if the flywheel runs without any wobbling, here is a very good method how you can rework a bad aligned axle: Drill a 4,5mm bore in a piece of plywood or in your workbench. Place the axle half the way into the fylwheels hub and clamp it with the screw. With a help of punch marks you can press the axle in the right direction to align it well. With a little practice this method works very well and you will get a really nice running flywheel, without any wobbling! The important point is, that the axle is clamped with the screw when you hit the punch marks. |Lock the flywheel that way, that the pivot screw No.53 of the D-crank arm is in 6 o’clock position. This is easy to do with the help of two normal pegs that you clamp to the flywheel. Connect crank arm and hinge block with the screw No.51. Place a washer No.57 between crank arm and ball bearing. Fasten the screw in a way that there is still a small axial clearance between these parts.
