My top goes down but won't go up. I found a leaky hyd actuator or strut (couldn't find anything in the factory assembly manual or the chassis service manual I have, so don't know if that's what they are really called) It's leaking where the shaft comes out of the body of the unit.

I haven't seen rebuild kits so it looks like a new one is in order. It looked like I could unbolt the strut shaft from the top frame and then the single bolt at the top of the strut body but the single mounting bolt is in a position that doesn't allow a wrench to fit on the nut. If I remove the 2 other bolts that are there it looks like I have to take the main connection to top frame off as well as the end of the strut. With the top up I think it will colaps on me doing it this way.

Anyone been through this recently that can help and save me some time and frustration?

In my research through all the topics on the site I was able to find this on bleading power top hyd actuators.

<BLOCKQUOTE>quote:</font><HR>Originally posted by Jeff H:
AHH, nothing like bleeding the power top. I never had a problem with the circuit breaker, but when there was air in the lines, it wouldn't make it all the way up. Don't run the pump when it starts sucking air or you'll burn it out. You need to crack open the lines at the bottom of the cylinders as you try to put the top up. When it stops making progress going up, close the lines and pull the fill plug out of the pump and let it down slowly to let air back out through the pump. It's messy and takes a lot of up and down, but it's worth it when it works right!
<HR></BLOCKQUOTE>

Is the fill plug the rubber plug on the passanger side of the unit mounted behind the back seat? Is there an alternative bleeding method that can be done with the top up?

Thanks in advance!!

Dennis, the hydraulic rams, pistons, whatever should be taken off with the top up. The top will not come down on you. There is no room to take them out with it down. Just unbolt them. Make a note where the hinge bolts to the body to make sure you put them back in the same place. I did a bunch of posts when bleeding my top.

I just went through putting in new cylinders.

1-Put the top up.
2-Unbolt the top single bolt from the piston rod.
3-Loosen the two bolts that are on each side of the cylinder bolt(good point Kevin, mark where they were before you loosen them). After they are loose you can move the cylinder and it will move the outside bolt into a position where you can get a wrench on it.
4-Remove the inside cylinder bolt. This one is a PIA!!
5-The inside bolt even though loose sometimes cannot be removed because there isn't enough room to back it out. If this happens you'll have to monkey with it until you can pull the cylinder out.
6-Remove the hydraulic hose from the cylinder.

After I put in new cylinders I used ATF in the pump. All I did was fill the resovoir about 75% then put the top up and down(with the resovoir plug off) and refill the cylinder each time until everything was full of fluid and all of the air was out.

Kevin & Paul - thanks for all the info... I knew I had seen some of it in the past but all the key words I used when searching turned up 200 threads to look through and I didn't stumble on Kevins...

Ok, I have the bad one out! Big warning!!! Even after draining the fluid out of one of these don't, I repete DON'T try to push the rod back into the cylinder... (I know where they got the idea for the supersoaker!! ) Man that thing shot 20' at least and it was like a shotgun about 4 feet wide!!I just finished cleaning up the mess!! To think I was so carefull inside the car... LOL!!

Another big thanks guys, the new hyd ram (I even learned the proper name for the part ) is in and the guidance given made it a very easy job. To bleed and top off the system I I found a section of plastic tubing that fit in the fill hole and wrapped one end with elect tape until the dia was the same as the stopper. Stuck one end in a qt of brake fluid and the taped up end in the fill hole and seated it snugly. Top up, top down several times as recomended and finally top down and replaced the plug. Top works better than ever!!

I'm thinking about starting an archive for convertible information and moving threads I find into it. Archives are finished posts and I don't think they can be added to I'll get with Al maybe a ragtop forum is something he would consider as well.

Thanks again I have an interior to put back together and some tranny fluid lines to work on!!

Dennis,

Give Dave a call @ Camaro's and Classic's

Here's a URL to his site for the lift cylinders @ $129.00 which is cheaper than most in cost. Also I suggest that you call him for info on a rebuild kit rather than replacing to keep costs down!

Good luck,

Tom
