Speedometer Drive and Driven Gears Two types of driven gears are listed for LaSalle 303 cars. The first type gears are for transmissions before unit 2-5781, and the second type gears are for transmissions after this unit number. Beginning with transmission unit 2-5781, the speedometer cable is smaller in diameter, so that a gear with a smaller hole is required. There is no 18-tooth gear of the first type listed in the table. If a car with the first type speedometer cable is to be equipped with a 4.07 to 1 axle, it will be necessary to order a second type gear, part number 876374, and drill out the hole to Ji-in. diameter. The gear can then be used with the first type cable. In changing to the 4.07 to 1 high gear ratio, it is necessary to change the driving gear, which is on the end of the transmission main shaft, as well as the driven gear. All driving gears have seventeeth but differ in lead and pitch. Driven gears with 18 and 22 teeth give slightly fast readings with 32 x 6.00 tires and slightly slow readings with 32x6.20 tires. 2. Installation of Cable Flange On 341-A and 303 cars the distance between the centers of the driving gear and driven gear is the same for all combinations. On 341-B and 328 cars, two different center distances are used, one for pinions with 16 to 19 teeth and one for pinions with 20 to 23 teeth. In order to make this possible, the end of the speedometer cable is eccentric. In one position, the cable gives the correct center distance for pinions with 16 to 19 teeth. When revolved 180° the cable gives the correct center distance for pinions with 20 to 23 teeth. The flange of the cable end has the figures "16-19" on one side and "20-23" on the other side. The cable should always be turned so that the figures corresponding to the number of teeth on the pinion are on top.
