SHIFT INTERLOCK MECHANISM

id051100669200

Purpose/Function

• The shift interlock mechanism provides reliable double-engagement prevention.

Construction

• During shifting, the shift rods, except for the one in operation, are locked in the neutral position by the interlock pins.

Operation

Neutral

• Because no shift rod is operated, the interlock pins are seated in the grooves.

1st/2nd shifting

• Movement of the 1st/2nd shift rod forces interlock pins A and C out of the 1st/2nd shift rod grooves, and the reverse shift rod and 3rd/4th shift rod are locked. In addition, interlock pin C forces interlock pin E out via interlock pin D, and the 5th/6th shift rod is locked.

3rd/4th shifting

• Movement of the 3rd/4th shift rod forces interlock pins C and E out of the 3rd/4th shift rod grooves, and the 1st/2nd shift rod and 5th/6th shift rod are locked. In addition, interlock pin C forces interlock pin A out via interlock pin B, and the reverse shift rod is locked.

5th/6th shifting

• Movement of the 5th/6th shift rod forces interlock pin E out of the 5th/6th shift rod grooves, and the 3rd/4th shift rod are locked. In addition, interlock pin E forces interlock pins A and C out via interlock pins B and D, and the 1st/2nd shift rod and reverse shift rod are locked.

Reverse shifting

• Movement of the reverse shift rod forces interlock pin A out of the reverse shift rod grooves, and the 1st/2nd shift rod are locked. In addition, interlock pin A forces interlock pins C and E out via interlock pins B and D, and the 3rd/4th shift rod and 5th/6th shift rod are locked.
