722.9: from transmission 2763720 from 30.04.2010 including 2675120 724.2: all
The ring has a slight step on both sides at the inner edge. This ring is easily to be mixed up with the former version which had no steps - all other dimensions and colour etc are exactly the same. If it is a problem if the older version is used instead of the the new design or vice-versa is not known to us. Both designs are still available from the transmission manufacturer. Therefore we suggest to use only the appropriate version.
