tighten using the KM nut and, before measuring
with the micrometer thickness gauge, then undo
it again.)
10. Make a note of the dimension “A”. Fit one
washer and shims , and using the micrometer,
measure the thickness so that the total thick-
ness is 0.10 - 0.20 mm more than the noted
dimension “A”. This will result in a preloading of
the bearing of 0.10 - 0.20 mm. See foldout/pos. <2/63>, <2/61>
