G'day all,
Bon_Scott, if you intend to remove the side cover from the crankcase, be aware that it's necessary to remove the oil seal first, as there's a bearing retainer circlip behind it! This prevents cover removal, if it's not removed first.
The shop manual method is to drill the face of the seal in two places on opposite sides, then screw a couple of short self-tapping pan head screws into the holes. Then use a pair of long nose pliers under the screwheads to pry the seal out - or a long flat blade screwdriver and spacer/fulcrum piece will work too.
