This gas spring provides a controlled lifting force to assist in opening and holding the bodywork panel of the host tractor. It is installed between the panel and the chassis, acting as a counterbalance that reduces the manual effort required to raise the panel and then supports it in the open position. Over time, the internal gas charge can leak, causing the spring to lose its lifting capacity; a worn spring will no longer hold the panel fully open, allowing it to drift downward. The manufacturer specifies the force output to match the weight of the original panel assembly, ensuring the panel remains stable when raised. On replacement, ensure the spring is compressed to the correct installed length and that the mounting sockets are clean and free of debris.
