A. The slow speed bands may be tightened by loosening the lock nut at the right side of the transmission cover, and turning up the adjusting screw to the right. To tighten the brake and reverse bands, remove the transmission case cover door and turn the adjusting nuts on the shaft to the right. See that the bands do not drag on the drums when disengaged, as they exert a brake effect, and tend to overheat the motor. However, the foot brake should be adjusted so that a sudden pressure will stop the car immediately, or slide the rear wheels in case of emergency. The bands, when worn to such an extent that they will not take hold properly, should be relined, so that they will engage smoothly without causing a jerky movement of the car. The lining is inexpensive and may be had at any of the eight thousand Ford service stations at small cost.

Q. How are the bands removed?
A. Take off the door on top of transmission cover. Turn the reverse adjustment nut and the brake adjustment nut to the extreme ends of the pedal shafts, then remove the slow speed adjusting screw. Remove the bolts holding the transmission cover to the crank case and lift off the cover assembly. Slip the band nearest the flywheel over the first of the triple gears, then turn the band around so that the opening is downward. The band may now be removed by lifting upward. The operation is more easily accomplished if the three sets of triple gears are so placed that one set is about ten degrees to the right of center at top. Each band is removed by the same operation. It is necessary to shove each band forward on to the triple gears as at this point only is there sufficient clearance in the crank case to allow the ears of the transmission bands to be turned downward. By reversing this operation the bands may be installed. After being placed in their upright position on the drums pass a cord around the ears of the three bands, holding them in the center so that when putting the transmission cover in place no trouble will be experienced in getting the pedal shafts to rest in the notches in the band ears. The clutch release ring must be placed in the rear groove of the clutch shaft. With the cover in place remove the cord which held the bands in place while the cover was being installed.
Q. How is transmission assembled?
A. [Cut No. 150] shows the transmission parts in their relative assembling positions and grouped in their different operations of assembling.
The first operation is the assembling of group No. 2, which is as follows: Place the brake drum on table with the hub in a vertical position. Place the slow speed plate over the hub with the gear uppermost. Then place reverse plate over the slow speed plate so that the reverse gear surrounds the slow speed gear. Fit the two keys in the hub just above the slow speed gear. Put the driven gear in position with the teeth downward so that they will come next to the slow speed gear. Take the three triple gears and mesh them with the driven gear according to the punch marks on the teeth, the reverse gear or smallest of the triple gear assembly being downward. After making sure that the triple gears are properly meshed tie them in place by passing a cord around the outside of the three gears. Take the flywheel and place it on the table with the face downward and the transmission shaft in vertical position. Then invert the group which you have assembled over the transmission shaft, setting it in position so that the triple gear pins on the flywheel will pass through the triple gears. This will bring the brake drum on top in a position to hold the clutch plates, etc. The next step is to fit the clutch drum key in the transmission shaft. Press the clutch disc drum over the shaft and put the set screw in place to hold the drum. Put the large disc over the clutch drum, then the small disc, alternating with large and small discs until the entire set of discs are in position, ending up with a large disc on top. If a small disc is on top it is liable to fall over the clutch in changing the speed from high to low and as a result you would be unable to change the speed back into high. Next put the clutch push rings over the clutch drum, and on top of the discs, with the three pins projecting upward (see group No. 4, [cut No. 149]). You will note the remaining parts are placed as they will be assembled. Next bolt the driving plate in position so that the adjusting screws of the clutch fingers will bear against the clutch push ring pins. Before proceeding further it would be a good plan to test the transmission by moving the plates with the hands. If the transmission is properly assembled the flywheel will revolve freely while holding any of the drums stationary. The clutch parts may be assembled on the driving plate hub as follows: Slip the clutch shift over the hub so that the small end rests on the ends of the clutch fingers. Next put on the clutch spring, placing the clutch supports inside so that the flange will rest on the upper coil of the spring and press into place, inserting the pin in the driving plate hub through the holes in the side of the spring support. Then turn the clutch spring support until the pin fits into the lugs on the bottom of the support. The easiest method of compressing the spring sufficiently to insert the pin is to loosen the tension of the clutch finger by means of the adjusting screws. When tightening up the clutch again the spring should be compressed to within a space of two or two and one-sixteenth inches to insure against the clutch spring slipping. Care should be exercised to see that the screws in the fingers are adjusted so the spring is compressed evenly all around.
