Is the belt twisted? It’s often difficult to tell. In our “Watch and Work” video, we show you what it is that reveals the correct directional positioning and why it plays an important role.
The multi V-belt with the PK profile is mainly used in 1.8 Audi and VW turbo engines – so it’s by no means a rarity! As its name suggests, it has a ribbed profile on both sides, which enables it to drive several units simultaneously.
Multi V-belts – try to remember these profile shapes:

Multi V-belts are only available with a few different cross-sections. The length and width of the belts vary depending on the usage scenario. The most important profile shapes: PK, DPK and PJ. |
The correct directional positioning of multi V-belts is vital!
Here’s a possible problem… when you take the multi V-belt out of its packaging, it can quickly become twisted. Then you can hardly tell what’s outside and what’s inside at first glance! However, if the belt is positioned the wrong way around, this can create several disadvantages. On the one hand, the outside of the belt is longer than the inside, so if it’s twisted, the belt may no longer lie taut; it will transmit less power – and wear out quickly. Apart from that, both sides of the DPK belt are made of special material to ensure optimal running. In our “Watch and Work” video we show you how to recognize the right directional positioning, so you won’t get stuck the next time you change the belt.
