- Automatic transmission
The transmission is particularly smooth and the gear ratios are optimized. There are no shocks, resulting in an appreciable level of comfort for the operator. The traction force is optimum under all
working conditions. Doosan DL420A Wheel Loader Shop Manual
The combination of these characteristics enables the loader to maintain high speed under all conditions, enhances breakout forces, and thus optimizes bucket filling at each cycle.
Daewoo Doosan Dl420a Wheeled Loader Service Parts Catalogue Manual The transmission has three modes of operation:
• Manual
• Automatic (automatic shift for all gears)
• Semi-automatic (automatic with a “kick-down” for first gear)
Axles Improved internal oil flow greatly reduces the temperature difference between the hub and the differential, as well as prevents premature disc wear due to overheating of the internal hub components.
Limited-slip ZF differential
The front and rear axles are fitted with limited-slip differentials. This automatically ensures maximum tractive effort and easy driving over soft and muddy ground. It also reduces the risk of skidding and,
at the same time, prevents excessive tire wear.
The brake discs integrated into the planetary reduction gears in the hubs are metal reinforced, ensuring long hours of operation and reduced maintenance.
