Hydraulic roof system failed

[Dutchyankee]

Well our 2nd hydraulic cylinder failed as I expected it to. So the access door along with the funnel with silicone hose needed to be put to use. I need to fill it every day to keep it working and keep the roof down.
Now I have the part number of the cylinder (from the €2K bill from MB which was mostly labor cost) and will order it and replace it myself when we get home (currently in the Dolomites)
I made a “dam” in the rear to stop the fluid from running down the back of the bus and on the ground. I use a small handheld suction pump to collect the “still clean” fluid so not to make a chemical waste mess. Always have reserve fluid with me.
I’ll post an update when I’m done.

Hello! How did you remove the whole panel? I have the same problem in Italy :/(

Difficult but started from the rear ( where I found all the tools needed to change a flat) but you can just cut a hole around the hole were the manual pressure release valve is. I can send another picture if you need one.

Here are a couple of pictures. By the way. Be real careful not to drop the brass plug from the reservoir take. It’s a pressure seal. Always put a rag to stop it from falling to the bottomless pit below. The last time I didn’t and it’s gone so I had to “Mcgiver” one from some materials I had. The ducktape is a temporary fix till I get home.

we are at the Zoldo Valley Ski Area with the bus! The right cylinder is now leaking fluid every time we move the roof up & down but I can easily top it up so it closed completely.
I knew this would eventually fail for this 29 year old bus here is a picture of where I cut an ez access opening

Hello. This time happened to me… during a travel abroad. Roof got up a bit then stopped. Couldn’t close it for the night. Next day made a hole in the panel (see photo), bought some hidraulic fluid (whatever brand! It works with everything!). Pour fluid in and managed to close the roof. It may be a major leak because there’s oil in the roof side rail coming down the drivers door (LHD) and tail gate (I guess oil it will damage the door rubber seals…)

Eu não tenho essa chave. Mas descobri que há uma abertura no interior, no painel traseiro lado direito (ver diversas fotos neste post) que dá acesso a um parafuso que sendo desapertado abre a válvula que descomprime o óleo e faz baixar a capota. Eu fiz uma abertura maior a volta dessa abertura existente para permitir acesso ao reservatório do óleo e repor o nível pois estou no momento a tentar reparar ou substituir um dos cilindros que levantam a capota que partiu e fez perder todo o óleo

Hello… cause found! Left hydraulic cylinder broke. Now I need help to find another one because I guess is not easy repairable. Does anyone know what is the part number? There’s no information on the part.
