Roof hinge leaking

[ivanchen1211]

Hi, have anyone experienced this?

I have relocated my roof pump

It was rusted, and after cleaning and add oil the roof started working.

That was like 2 monthes ago. But recently both side of the hinge cylinder started leaking.

I added power steering stop-leak but it seems not helping.

The roof still works perfectly as long as there is still enough hydraulic fluid in the pump resorvior.

The leaking speed is higher when the roof is down compare to when the roof is up.

Anyone has experienced this? And anyone tried other kind of stop-leak with successful story?

Are you sure it's the rams leaking? A lot of times it is the bottom pipe where it turns through 90 degrees to go into the hinge, especially if they've been sat in water: get weak and a pinhole opens.
So you either need to fit new pipes, or at worst case new hinges. Neither is too bad a job, just time consuming.
Pipes can be done in situ but to change the hinges needs the roof off.

You mean where I circled?

It was flooded with water but not that high

It there a O ring that seals the pipe that goes to the cylinder?

Yes that's where they fail.
No o-ring. The pipes 'kick' a little bit every time pressure goes through them. Once they get rusty they eventually fail right on the outside of that bend.

Thanks for advice!

I've used scope to look around the cylinder, seems not from the bottom, maybe from other pipe...?

I think the only way is to take all roof out and exam where is leaking before I order 2 rebuild hinge...
