I spent a rare hour tidying up the workshop the other day and came across a pot of all the scrap bits I replaced which reminded me of a question I had during assembly. On the 400 manual it specifies the orientation of the shell bearings and requires the locating cutout to be facing forward. So why is this required and what is the significance should some one disregard the advice. Before anyone asks, no I haven’t, I just can’t see an obvious reason for the requirement and I’m curious.
Cheers,
Greg
