David,

I received this response from Saito today. I hope this helps with your customer.

About rear bearing for FA-72;
In the past, there was an incident that the retainer of the rear bearing was broken and the balls spread in the crankcase.
After that, we’ve chosen the shielded bearing for several engines.
The shield has appropriate clearance for lubrication so he doesn’t need to be worried.

Hello Saito Team,
A customer is requesting information on the FA-72. He is wondering why the rear bearing is shielded. He believes the rear shield prevents the bearing from being properly lubricated, any ideas?
