NOTE:
●
When reassembling the lower unit with
the original gear case and inner parts,
shim selection is not required.
●
When replacing the gear case only, read
the numeral preceded by “F, R, P” and
adjust the shims according to the differ-
ence between numerals of the original
gear-case and the new gear-case.
●
If the bearing(s) and/or gear(s) are
replaced, carry out the shim selection.
