Sectional view of the “Triple-silent, Syncro-mesh” transmission [Left Column] quadrants are graduated as a guide to the amount of movement. See Figs. 100 and 101. Moving these plates up or down shortens or lengthens the yoke travel. To adjust the yoke travel the pedal bracket must first be moved far enough from the transmission case to gain access to the yoke adjusting quadrants on the left side. [Right Column] The yoke travel is measured in the same manner as that on the series “A” cars, except that a separate measurement is taken for each yoke. The front yoke is measured for forward travel, and the rear yoke for rearward travel. The travel of each yoke should be 3/32 to 5/32 in. The two rear quadrants, one on each side of the case, are for adjusting the travel of the rear yoke which operates the intermediate speed drum. The front quadrants are for adjusting the travel of the front yoke which operates the high speed drum. To change the yoke travel, if the original adjustment has not been distributed, the yoke trunnion plates should be turned up or down. It is extremely important that the two plates for each yoke be moved equal distances and located in exactly the same position as indicated by the graduated scale on each plate, in order to keep the yoke pivots in accurate alignment. To adjust the rear yoke, turn the two rear quadrants up or down, a little at a time, to give the proper amount of yoke travel. Turning the quadrants up decreases the yoke travel and turning them down increases the travel. The two quadrants should be Fig. 96. Cut-away view of transmission showing helical gears | ||
