6. 2nd Gear. The transmission is shifted from 1st to 2nd gear by lifting upward on the gearshift lever. This causes the shifting pawl to move upward, turning the shift drum clockwise, looking at the left end of the drum. Gear 1 moves to the right, disengaging from gear J, and returning to its neutral position. Gear C then moves to the left, engaging gear B. The transmission is now in 2nd gear, as illustrated by Fig. 34. Gear C's opposing gear, H, is not locked to the layshaft, so it just turns freely. However, gear C has engaged into gear B, therefore, the power flows from C to B, and onto the layshaft through gear 1, which is locked to the shaft. The layshaft now turns gear F, which drives gear E, causing the sprocket to rotate. To calculate the ratio for 2nd gear, divide the number of teeth on gear 1 by the number on B. Divide the number of teeth on E by the number on F. Multiply the two resulting figures together, and the answer is the ratio of 2nd gear.
