New workshop video highlights the motor belt drive

In the new ‘Parts Specialists’ workshop video, Lars and Kevin from DT Spare Parts take a close look at their truck and have practical hints and tips up their sleeves, while also discussing the causes of the various error patterns.

The belt drive is driven by the crankshaft. The task of the belt drive is to transmit the rotary motion of the crankshaft to various auxiliary units such as the air conditioning compressor, the generator, the water pump or the fan. However, the function of the belt drive is no longer given in Lars’ and Kevin’s truck, as one of the two belts is broken.

As a result, the water cooler has already been damaged. To prevent further malfunctions, the duo checks other components in the belt drive. First of all, the belt tensioner must be loosened. An important tip from the Parts Specialists is to note the exact position of the old belt. This facilitates the correct installation of the new model later.

Making the daily work of other workshop colleagues easier is the declared aim of the Parts Specialists. For this reason, Lars and Kevin have prepared a wide variety of error patterns.

Among other things, the two show a pulley whose position has shifted. Possible reasons could be dirt, a defective vibration damper of the crankshaft or engine vibrations.

In addition, the Parts Specialists present a belt tensioner whose material abrasion indicates that the belt has not run properly, which can cause it to jump off or tear. Further error patterns, including potential malfunctions, can be seen in the video below.

In order for Lars and Kevin to get the truck running again, the complete belt tensioner set from DT Spare Part is installed after removing the corresponding parts. Due to grease leakage and play on the bearing, the fan bearing is also replaced.
