from intermediate ring for dowel pin
centered clutches - see page 30 - 18). Guide

(larger liner springs or longer hub) is between
pressure plate and intermediate ring (see
page 30 14).

arrow/black side) are offset 180" opposite
each other.

Make sure that central shaft I moves easily.
Then remove the clips from underneath
the pressure plate bolt heads. If applicable
