• As the clearance between the housing and sleeve is very
narrow, do not forcibly draw out the sleeve.
(When reassembling)
• When fitting the sleeve (9) and spool (11) assembly into the
housing (12), apply clean transmission oil to the assembly and
then insert it while turning it slowly, taking care so that the parts
are not inclined. Also, pay attention to the dowel pin so that it is
not caught in the housing grooves. If the pin is caught, adjust its
position with a fingertip.
