|Initial design initiated early 1950s.
Which is equivalent to a Ford model-A (just not as famous). The U-411 could be seen as the
Ford model-T. The 404 is a great truck, but light-duty drive components compared to the
406's / 416's.
|Initial design initiated mid 1960s.
A major rev in the transmission happened about 1967 with type-F being the earlier one and
type-G the more common newer one (same technology but different bearings, etc...)
|stock engine : gas 2.2l M180 (7:1
Same as in the 220S passenger car except lower compression ratio and single carb. Some
later and rare models had the 2.8l M130 engine from the 280S passenger car but with lower

(up to 120hp)
Same engine is being used throughout most of the Daimler-Benz medium duty trucks. It's the
