When the retraction tank is made locally, finish it so that
the welding bead does not protrude on the inner surface
of the tank. The tank guide will hit the bead, causing
motor born-out. The gap between the tank and tank guid
is 1 mm. Also when installing the tank, orient the welding
bead so it faces the port or starboard direction.
