Cadillac Models & History H 1908

TheMODEL H for 1908 was the same as the 1907 Model H except the coupe body was dropped from the line. Also the touring body was now similar to the Model G with continuous molding across the center of the doors.

The model H no longer supplied an engine speed governor or the interlock between brakes and clutch. Tire size increased to 34 x 4.

DRIVETRAIN OPTIONS

  • On the models M, S & T, different combinations of 9 or 10 tooth driving sprocket with 31, 34, 38, 41, or 45 tooth driven sprocket gave ten possible ratios from 3.1:1 to 5:1.
  • Driven Sprocket
    31 34 38 41 45
    9 tooth drive sprocket 3.44 3.78 4.22 4.56 5.00
    10 tooth drive sprocket 3.10 3.40 3.80 4.10 4.50
  • Lower ratios for runabout to be run on smooth, level roads to higher ratios for loaded Delivery to be run on rough, hilly roads.
  • Instructions for changing sprockets were available for owners, but the change involved disassembly of the transmission and rear axle — definitely not a “quick-change” set-up.
