1999 500 SL Soft top issues (hydraulic fluid)

Hello all:

I was raising the soft top of the 99 500 SL,
it started up just fine, then reversed and returned back inside
it's compartment. When I got out of the vehicle, I noticed hydraulic fluid
on the ground in front of the drivers side rear tire.

Never owned a 500 SL before and not sure what this symptom indicates or
where to begin.

Thanks in advance for your suggestions.

All the best,

Joe

Please use the search feature on the forum. The is a massive thread regarding these issues. Your seal will be leaking from a lifting ram and most likely need to send all hydraulics for a overhaul

It happens to every owner of a SL R129 some time or the other. Seals in the hydraulic cylinders wear out.

Search this forum.

Might add that it happens eventually to every Mercedes with a hydraulic operated hard top or soft top.

Refer to this diagram from the TopHydraulics website to see the location of your vehicle's 11 hydraulic cylinders: https://www.tophydraulics.com/conten...benz-r129-info. You'll see that the left-side roof drive (main) and bow extension cylinders may be leaking.

If a cylinder is leaking you will see evidence of hydraulic oil at the point where the rod of the cylinder leaves the body of the cylinder.

At a minimum I would remove and rebuild the leaking cylinder and the cylinder like it from the other side of the car. For peace of mind you may wish to rebuild all of them at the risk of unnecessarily rebuilding a cylinder which has been serviced in recent years.
