Please follow my advise to perform this procedure better than in this video. After sucking old oil out remove the return line from the pump- one nearest to rear of car. Fill the oil tank to normal level. With an assistant start the engine and cycle the roof up and down whilst catching the old fluid from the return line into an empty container and keeping the oil tank topped up. Once you have all old fluid out of the return line and the colour of return fluid is clean stop. Fit return line back onto pump and make sure oil tank level is between minimum and maximum. Using this procedure ensures you arent mixing any old fluid from the lines with new fluid in your tank.

Wrong fluid. Dont use the multi grade. Use the Mercedes hydraulic flyid p/n 0009899103. The additives in the multigrade fluid will immerse water and make the rest of the system fail sooner. Hydraulic ZH-M fluid makes the water drop to the bottom of the reservoir.

Has anyone tried putting Seafoam Trans-Tune in one of these roof systems? It works great to help condition and swell seals on hydraulic systems, wasn't sure if anyone tried it on an SL.

On your version of the pump, which line is the return line out of the two? I would like to disconnect the return line so that I can get out all of the older fluid in the system when replacing the tank with the new fluid. Many thanks for your videos

My hard top wont latch in the back even when I try to do it manually with the speciality tool from Mercedes on the red tabs in the trunk. What should I try if changing this fluid doesnt work?
@fupabox4 жыл бұрын
that's an odd one . Never seen one not latch manually . Possibly something jammed in the mechanism ? Have you tried to see if the rear is already in the down position and unlatching the locks first ?
@fupabox4 жыл бұрын
Also check that the latch pins on the bottom of the hardtop are aligned correctly on the holes . You can loosen them and adjust . If they are too far out of adjustment the manual latch may not grab them properly .. Just checked my manual and that seems to be the only other reason they wouldn't be able to lock
@flawandalason4 жыл бұрын
I put in new fluid and the reservoir was practically empty. The roll bar works amazingly. The hard top will lock in the back now but it wont sit down all the way. When I try to lock the hard top into place, it will but the roll bar will move up by half an inch then a thunk can be heard after it stops. The seals in the front are busted since whenever I try to use the roll bar or the hardtop controls it will leak. I'm gonna try to get help lifting the hardtop out of place since I don't feel comfortable doing it alone and get a direct look at the pins.

@@flawandalason you need to fix the front cylinder leaks first , The system relies on each area retaining its pressure or the other areas will gain and lose pressure in weird ways ..IE the roll bar moving and clunking .

Hi there, I've got a problem with my `95 A124 Mercedes, after replacing seals in the cylinders of the main hood lifters, the roof does not open. I had to let it replace, coz the left one was leaking badly (my mechanic replaced both sides just to be sure). The one that (un)locks the roof was replaced last year (received new seals too). Hydraulic fluid was topped up to maximum level (original one from MB). Now when I try to open the roof, the rear lock opens but the roof part where the glass window is lifts very very slow, and if finally rises so the front part can rise nothing happens. The button to open the roof blinks (I think even right from the moment on i pull it to open). Did you have such situation, do you know what the reason might be? Te engine runs when I operate the roof and I'm in P mode of course.
@fupabox6 жыл бұрын
a few things could be the culprit . start with the easiest .. window sync. Unhook negative battery terminal (key out of ignition while battery unhooking and rehooking it up ) after 10-15 seconds re attach the neg battery cable. start the car and push the window switches one at a time.. up, and hold 5 seconds after it reaches the top . lower window and hold 5 seconds once all the way down . Do this for all the window switches. The roof needs to verify the windows are down to allow the roof to open past 1/2 way. It verifies by counting the number of times the window motor has turned from full up to full down . if the roof still won't open . check the microswitch on the hard tonneau cover (they need to confirm the tonneau is open ) on the right tonneau hinge . The other microswitch on the top bow extension could also be not operating.

Hi mate, thank you for your reply, and sorry for my late. not easy finding a minute time when small kids at home. I let my mechanic change the seals in two side cylinders and from my observation nothing leaks now. I just topped up the hydraulic fluid and operated the roof while the fluid container was open. I thought it was a good way to bleed the mechanism. I guess I was successful as after that I had to top up again and the mechanism worked a bit faster. The lid that covers the roof when it's closed didn't popped up unfortunately and I think the cylinder that opens and closes it got stacked. The window opening/closing mechanism before /after opening / closing the roof never worked, but the right rear window can't open, since the slide mechanism is broken since a couple of months now. Perhaps this might be the reason why the lid wouldn't open to hide the roof. Just my assumption. Do you know by any chance how to bleed the mechanism? I think it might be full of air, as the fluid leaked previously. I also unhooked the battery as you suggested and tried to operate the windows as you told me, unfortunatly it didn't helped. Anyways if something pops up to your mind what the reason can be or where to look for a fault please let me know, my eMail is bartosz.chrzanowski@gmail.com I appreciate your support.
