H520 Gimbal Dampener Replacement

[GRFD8121]

Has anyone had to replace the little silicon filled black rubber gimbal dampeners which sit between the two gimbal places above the E90 camera? One of mine is leaking a bit of very fine silicon oil. I am also attempting to locate a repair manual with a schematic diagram of the H520.

They can be removed by using a small flat blade screwdriver. They’re fairly stout and robust and usually will only leak after a hard crash. Replacing them is easy as well. Each damper has what I call a fat end and a skinny end. The fat end goes into the mounting plate that is closer to the camera. The skinny end goes into the mounting plate that connects to the drone. The easiest way to install is by pinching the fat end of the damper and start working it into the mounting plate. Once it’s partially in there use your index finger and install the rest of the way. Do this for the other three as well. Once all four are installed, fit the other mounting plate over the dampers making sure that plate is flush with the other plate. Install these the same way you did the first round. As I said, these dampers shouldn’t leak, especially new ones. New ones will also have a small amount of oil on them. My belief is this is applied on them to keep them from becoming brittle and therefore being prone to leakage. The part number for these dampers is YUNE90101. Hope this helps.

I would not use a screwdriver or any other sharp tool near the dampers. To remove them, a gentle squeeze near the plate surface and then light pull with a bit of rotation, and it will come through.

The easiest way to mount the dampers onto the plates is to use the dental floss trick. Just form a loop of dental floss about 10-15cm with a knot, then from the opposite side push the loop through the plate hole, wrap the dental floss around the damper recess a few times, then gently pull it through...... works every time.
