Figure 5
The first two letters (initials of ”MEDIUM DUTY”) and the first
number denote the series.
The second figure can be ”0” or “5”. If it is “5” the transmission
has higher gear ratios for the first, second and third gear.
The third figure corresponds to the number of available
forward gears.
Identification plate
The identification plate is located on the right-hand side of the transmission at the rear.

detail number
The fourth figure is different from “0” when the
transmission has relevant building changes compared to
the
basic
production
model.
For
example,
on
transmission MD 3066 the final figure “0” is replaced by
figure “6” because this type of transmission is fitted with
a clutch having a higher number of discs to be used on
Diesel engines with uprated power.
The letters refer to additional equipment, such as: power
takeoff prearrangement, retarder, transfer case.
