NOTE: It does not matter if you are converting the cylinder from minus to plus or from plus ...To calculate the spherical equivalent, algebraically add 1/2 of the cylinder power to the sphere power. The cylinder power and axis are then deleted from the equa-tion. Thus, the spherical equivalent is the same whether we use the plus or minus cylinder format. Example 1: Find the spherical equivalent of -2.00 +3.50 x 095.

3 Piston-cylinder clearance. When you know the exact cylinder bore size, you can check what piston diameter you need. With all VHM pistons, a packing list is included in the box. The minimum piston to cylinder clearance is indicated on this list. For example: your cylinder bore is Ø54.02 mm and the minimum piston to cylinder clearance is 0.07 mm.
