THE SPLITTER gearbox option now being offered on Mercedes-Benz 1632 S tracthie units (CM road test June 22, 1979) provides an overdrive top gear ratio of 0.85 to 1 and an intermediate ratio between each of the remaining seven gears. A 5.22:1 rear axle ratio replaces the standard 4.64:1 to further improve the performance flexibility and keep the maximum geared speed within reasonable limits.
The splitter assembly used in the ZF GV91 gearbox is similar to that used in the GV 90 fitted to the I626S tractive unit and is located in front of the normal gearbox. -£990 is added to the basic chassis price if the option is specified. On all Mercedes truck chassis with range-change gearboxes, the "double H" range selection system is now used instead of a separate toggle switch. Range changing is effected by moving the gear lever across the neutral position. Separate detent springs in each half of the gate assist the location of gear positions.
