•
Visually do a check of the crank and the bedplate for unwanted material.
•
Visually do a check of the edge for unusual colors.
5 Do Step 4 again for the other cranks.
6 For each crank calculate the vertical deviation d
vert
as follows:
6.1 Calculate the average value d
1’
for position 1 and 5 with the formula
d
1’
= [d

] / 2.
6.2 Calculate the vertical deviation d
vert
with the formula d
vert
= d
