| 436 NEW STUDEBAKER CHAMPION Transverse section of Champion engine and side view partly in section either Hayes or Schwitzer-Cummins make. Both the generator and starting motor are of Auto-Lite make. The battery is a Willard, of 90 amp-hr. capacity. It is located on the engine side of the dash, under the hood, and has its positive terminal grounded. Generator control is by a vibrating voltage-control unit. The maximum charging rate varies from 28 amperes with the generator hot, to 30 amperes with it cold, at 3200 and 3000 generator r.p.m. respectively. The battery cut-out closes at 9.1 m.p.h. and the maximum charging rate is reached at 32.5 m.p.h. The starting motor, which develops a stalling torque of 5.5 lb.ft., drives through a Bendix drive and flywheel gears, the latter having 9 and 124 teeth respectively, making the reduction ratio 13.77. The clutch is a Borg & Beck, with molded lining on the forward, and woven on the rear side of the driven disk. It is of 7 7/8 in. diameter and is provided with cushion springs and damping means. A Warner Gear three-speed transmission is standard equipment and gives the following ratios: Low forward, 2.665; intermediate, 1.564; high, direct drive; reverse, 3.554. A solenoid-controlled automatic overdrive is offered as an extra on all models, the over-drive ratio being 0.722. Final drive is through a tubular propeller shaft with prelubricated Spicer universal joints, and through hypoid gears with a ratio of 4.56 to the semi-floating type rear axle. Ad-justment of the rear-axle gears is effected by means of shims. At the front the car has the familiar Studebaker “Planar” type of independent suspension on a transverse semi-elliptic spring, which, however, has been improved over previous designs. The spring, which consists of 11 leaves of silico-manganese steel, with the second leaf of the “wrap-per” type, measures 47 1/2 by 2 1/2 in. It connects to the lower end of both steering heads, the connection being of the threaded-bolt type. At the center the spring is clamped to the box-section front cross member of the frame. Metal spring covers are standard equipment on deluxe models. The upper end of the steering head is held in position by modified wish-bone-type links connecting to the frame at widely-spaced points.
