I recently had all of my roof cylinders replaced.
no more leaks, but now the left roll bar pawl cylinder is not getting pressure to unlock.
It’s a single line so do I need to prime it in some way for fluid to get in?
The roof works fine when the bar is down, but i have to manual pull the lock spring to lower the bar if it’s up before opening the roof. That side also makes a ratcheting sound when the bar is going up because they lock is not being disengaged.

Any advice or suggestion is appreciated.
Check out a YouTube video by MrMarco6900. He had a similar issue. near the end of the video. Great video. may be of some help.
If this is the video, there are a lot of good tips. Unfortunately, before I can get to any adjustments, I need to troubleshoot why there is no pressure getting to that specific cylinder. The rest of them work fine. I removed both lock pawl rams and only one of them is moving when I press the roll bar buttons.
Strange part is I know that it was getting pressure before I changed it because that's where all of the fluid was shooting out. I guess it's possible that there's a clog in the line of the new unit. However, all of my units from Top Hydraulics have been great.
I even disconnected my consumer battery in case something in the circuit needed a reset. So close to having my roof back to 100%. For now, I'm leaving the roll bar down so that I can still use the top.

Yes thats the video
didnt he say that he had an issue with it working due to some kind of misalignment and how to fix it. I thought maybe the ratcheting were the teeth not engaging properly.
Yes, but his cylinder was working. In mine, I removed both lock pawl cylinders and pressed the button for the roll bar.
Only one side actually pushes out the piston rod, while the other one does not. I might try bleeding out air if I can find a syringe small enough to shoot some fluid into the line.
If you removed the whole line back to the pump, You might double check that the hose is in the correct port at the pump. You also might be able
to swap the left and right hoses at the pump to see if the problem follows.

I’ve been out of town but will have some time to troubleshoot in a couple days. Does anybody have a reference of all the line numbers (engraved on the pump) and which cylinders they go to?
My searches were unsuccessful. I want to start with swapping the left and right lines at the pump.
Pawl cylinders are 102 and 103. There is only one valve for the two pawl cylinders plus the roll bar cylinder, so if properly connected it should have pressure.
Thank you!
That is exactly what I needed. I swapped 102 and 103 which verified that both lines should be getting pressure. I might have been unlucky and received a defective rebuild. It's almost as if there is a clog in the line.
After all of the troubleshooting steps, it was determined that the rebuilt cylinder was not getting pressure through the line. A replacement was sent to me and it unlocks as expected.
Now, if the roll bar is raised, I have to reset the roll bar each time I want to lower it (Hold raise button until click, then lower it). This is preventing it from automatically going down when I try to open the roof.
Any ideas on this one?
Also, When raising the roll bar, if you hold the button, does the pump continue to run even when it's completely in the upright position? Mine does not stop so I'm wondering if the S83/10 limit switch is not detecting the up position.
All fixed!
I watched the above YouTube video again and tried the adjustments at the end of the video involving the two screws at the bottom of the other lock pawl. After three tries, all good now.
Thank you everyone!
It’s great to have all new cylinders and everything working properly.

My car behaves like this when operated manually...Is this normal?

I’m having the same exact issue but for the life of me can’t get the roll bar adjusted. I raise the roll bar, release pressure on the system, then unscrew the two bolts at the bottom, I can’t get any movement out of it. I’ve tried prying, tried with the roll bar up and down, tried releasing the little lock spring, no movement. Any tips on exactly how you did it? Thank you
