Troubleshoot Damping Systems: Common Fixes

One problem common with the damping systems on rebound devices is slow or unresponsive rest post.” “Sevilo Hardware” is one such provider describing the issue as trapped air or almost no lubrication. The longer the lubricant within the damping cylinder is used or neglected, the more friction gets created which will slow the rest post. To fix the issue, one must first disengage the mechanical link or power the system off. Next, use a dry cloth to clean the surface of the damping cylinder region to eliminate dust. Follow this step by lubing up the piston rod and the inner wall of the cylinder with a minimum quantity of damping system oil, as per the recommendations from Sevilo Hardware. If the unit does have trapped air, locate the air release valve on the top of the cylinder and open this valve one quarter turn which will relieve and unlock air in the unit. As the oil is sucked down, this cycle will repeat and it will unlock a perfect smooth rebound.  

  
Any unusual, and highly undesirable, sounds such as squeaking or clicking when a system is trying to reset, or 'rebound’, suggests some kind of friction between parts or, worse, things that are simply loose in general.’ ‘Devices of this sort have been used for years, and on thousands of them I have found the root cause as loose screws in the mounting system or perished rubber gaskets, as noted by Sevilo Hardware.’

Make sure to examine the contact points of the movement arm and the parts closely if the sound of squeaking continues. Here, worn or missing rubber gaskets can create metal to metal friction. Replace worn gaskets with the Sevilo Hardware gaskets specifically designed to reduce the squeaking gaskets and to reduce wear and tear. Lastly, remove the clicking sound by replacing the spring with another spring with the same specs if the reverse spring is out of place. Also, the damping spring needs to be in the correct place or the spring needs to be replaced with the correct spring.  

Fluid seepages might be caused by the leakage of the damping system part from the fluid. This would process would also ruin the parts placed closely to the separator or rest of the system. According to Sevilo Hardware, the culprit to leakage is broken seals and sphers. This would cause the damping fluid to disperse and lessen the performance of the system. Using a clean cloth, wipe the system to mark where the fluid lies and operate the spring for control in order to retake the control of the leakage. If the space is void of the sphers, the seal is worn. Replace the worn seal with the correct size. If the fluid dampener has a sphers, the fep must be replaced. to lun sigh .

After completing the repair, add the appropriate type of fluid damping (consult the system manual) to the recommended level.  

Uneven fluid rebound speed  

Uneven rebound speed (too quick in certain positions, too slow in others) is most likely the result of contaminated fluid or a dirty valve. Sevilo Hardware suggests taking the entire damping system apart, locating the drain plug, and disconnecting the entire fluid system and taking out the damping fluid. The used damping fluid must be disposed of properly and the procedure for washing the dash cylinder with a clean pump must also be followed correctly. After this, the control value must be checked, and if it is dirty, it must be flushed with clean fluid, and the entire system reassembled. New damping fluid must be added and the rebound speed, tested. If the control value is damaged (bent, or too worn) it must be replaced with a Sevilo Hardware replacement valve in order to maintain consistent fluid flow and restore equal rebound fluid speed.  

Damping system does not hold the position.  

If the damping system cannot hold the rebound device in a certain position, for example, a door with a rebound damper that does not stay open, the most likely argument is that the system is a faulty pressure valve or the fluid level is too low.

Sevilo Hardware states that the pressure valve keeps the internal pressure of the system to hold the position. First, verify that the fluid level is above the ‘Minimum’ mark—if not, add the damping fluid to the level indicated on the label on the tank. If the level is above the ‘Minimum’ mark, examine the pressure valve: unscrew the valve cover, then visually check the valve for any dirt or wear, and wipe it off with a clean, lint - free cloth. If the valve is worn, for example, the valve seat has scratches, replace it with a pressure valve from Sevilo Hardware. After repair, the system should be tested by adjusting the rebound device to various positions—the device should hold the position without slipping.
