Rubber tie rod for locking the new Dhollandia type control unit is used as a closing and tightening system for various Dhollandia hydraulic power unit covers. These include: Hydraulic power unit cover - Dhollandia plastic only code 51308D, Hydraulic power unit cover >2013 -EU- Dhollandia code 51309D, XW push-button control box - LM article 51310D. The rubber hooks or tie rods are fixed in the casings or control unit cassettes and once the cover is placed, it is pulled by stretching it, until it is placed inside a fork in the lower part of the cover. In this way, everything remains stable and the lid is guaranteed its natural position. Be careful to wait too long for any replacement, in case of damage. In fact, it could happen that if the cover is not held correctly, even while the vehicle is running, it could blow off and become dangerous for road traffic.
