HOW TO MEASURE LEAF SPRING
You can measure the lenght from the center line of eye following the curve of the main leaf as shown by A and B
You can measure the free arch as shown by C
You can measure the packing thickness as shown by D
You can measure the eye to eye free length as shown by E
HOW TO MEASURE BUSHING
A = Outside diameter
B = Lenght
C = Total lenght
D = Inside diameter
E = Leaf spring eye diameter
HOW TO MEASURE U BOLT
A = Diameter
B = Widht
C = Length
Round bend
Semi round bend
Square bend
HOW TO MEASURE WEIGHT
a(Length) x b(Widht) x h(Thickness) x Density of Iron (7,85) / 1.000.000
a,b and h should be in mm and the result will show you the weight in Kg
