I have the answer now to my earlier question. When the 2 3/8 inch long M6 bolt ( original factory bolt ) is placed through the motor brake with a lock washer there is 1/2 inch threaded into the motor case. With the motor brake off the cart I threaded a new M6 bolt ( with a small O-ring placed on it as a marker of depth ) all the way into the hole on the motor case. It threaded in with ease a full 1 inch. If you can find an M6 bolt 2 5/8 inch long, ( add a lock washer ) there is still 1/2 inch of virgin threads down there to thread in to. Need to ( carefully ) run an M6 tap in there first to clean up any burred threads that might complicate the new bolt going in. Should tighten to recommended specs with no issue.
