DISASSEMBLY(Cont’) SM-97 REASSEMBLY SM-97 NOTE: As machine is being driven in forward direction, a counterclockwise torque is applied to the internal gear, when looking at the open end. This gear is prevented from turning in reaction member by the latch (Pc. #34), which can be released by tripping release pawl (Pc #36) while applying a counterclockwise torque to internal gear, which is then free to continue rotation in that direction.
