Hydraulic Cylinder Roof Repair Kit Compatible With 04-11 Mercedes SLK 280 350 55 AMG R171

Afeter reading on the internet I thought this was going to be a major project.. Seen special tools for removing the plunger. WTF?I replaced the Oring in less than 15 min with a drill a pick and a pair of plyers to get the clip back on. No special tools..Drilled a small hole to access the clip.Popped the clip out..Pulled the plunger out..Removed the old seal..Streched the new oring onto the shaft over plunger where the old seal was located..Pushed the plunger back in with the new oring..Popped the clip back in place..Filled the pump up with fluid..Done..Works perfect..No leak..

When I first got the kit I said to my wife "I just paid $15 for an O-ring", but the directions were great and easy to follow. Note - the hydraulic pump is located between the 2 seat behind the flip down luggage holder. Mine was low on oil and needed filling. Need to remove hex head bolt on back of pump to add fluid. I had to remove 40ish bolts. Give yourself lots of time if you want to check or add fluid took long than replacing O-ring. I has to goggle You Tube videos to find and get to the pump, plus how to manually close the roof to make the system work after replacing the seal. If links to this type of data were added it would make the kit more complete.
