    Hi we have the inside of our camper torn apart... we can't seem to get the lift post out to get at the springs... was there a bolt or something holding it to the spring tube... how did you get it out...the instructions sound like it should come right out...not so....can you help us ?

    thanks.

    I have the spring new in and put back together. I put a new clutch assembly in but the cog and gear does not work. What keeps the shaft of the lift nut from just spinning on the inside of the gear? Am I missing something obvious here?

    Did you remove the press fit bushings? When you wind up the system with the crank, it screws the clutch nut on to the clutch shaft. The clutch will then press against the bearing, causing it to "sandwich" the ratchet gear between the bushings, and making the shaft, ratchet gear, and sprocket / clutch assembly turn, thereby turning the drive sprockets and moving the chains.

    There is also an e-clip in front of and behind the clutch nut. Make sure yours aren't missing. The one behind the nut is almost buried in the bushing, so it can be a PITA to get at.

    I hope this helps. Holler if you need help.

    Hi everyone, I'm new here and a first time owner of a pop up trailer. I recently bought a 1992 rockwood and the chain is broke. I am not too mechanically inclined so i had a buddy look at it. Turns out he knows just as much about it as i do. What he is not sure of is how the chain goes on. Does it go through the tubes. i have diagrams, but still can't figure it out. I can't get the chain through the tubes and can't take the tubes off, cause they are welded on. I'm soooo confused with this. Can anyone out there help me with a step by step on how to do this. i really appreciate it. Thanks

    thanks for the diagram..everything is back together, cranking up and down, but it won't stay up now.

    hi guys i have a 98 rockwood signature series pop the does not want to lift from the front. i have removed a lot of the cabinets and bathroom to have access to the gears, chains and springs. the chains appear to have been fixed with bicycle chains and one of the springs has a kink. i would like to replace the spring and buy the two new chains for the both of the springs so they are like they should. i did replace a sprocket once already but know it will not lift right. does any one here have any idea where to order the correct parts. thanks

    Do you hear a "clicking" sound as you raise the roof? I'm going to guess not. If not, you're ratchet pawl is out of place and possibly damaged. It is essential to holding everything up.

    ok i got a reply to order some parts. i do have another question. what is the best way to make sure that both fornt and back roof go up together. is there an alignment pin that i should look for? also i was looking at the picture above and see that the chain the turns the rod to lift the back part is tight all the way around on mine only the top part of the chain is tight and the bottom part is loose. should it be like that or should i try and tighten it up. thanks

    They are connected by a solid shaft, so as long as they are aligned to begin with, I can't see any way that they could get misaligned. You could always raise the roof and brace it, remove the chains to the connecting rod, level the roof, then reconnect the chains. It's a pain in the butt, but you would only have to do it once.

    It's hard to see, but the bottom is a little slack. The chain isn't long enough to allow enough slack to remove the chain. That may be why it looks tight.

    Hey Joe! I am really hoping you still get emails and will pay this site a visit, as I see you haven't been on here in a while (but you seem like the all around PRO). I am new to this blog and to my 1976 Rockwood. I stumbled across a (theoretical) gem of a camper recently, with the only issue lying THE LIFT SYSTEM. The previous owner attempted to lift the roof while it was still buckled down on one corner. Needless to say, it has issues. Our first attempt we were able to crank the roof up while manually lifting the the rear passenger side corner. We were able to crank (with great effort) the roof all of the way, however, we couldn't let go of the handle without it winding back uncontrollably. After the camper was moved and we attempted to lift it again, we couldn't get it past a couple of inches, with the back corner still no functioning whatsoever. First inspection inside (after removing the necessary materials to access the front corner/crank shaft access, we found a broken pull pin. But this is not our (only) issue. We replaced that, but there is still much resistance, some apparent "slipping" when cranked up, and a stopping point (the pull pin actually broke AGAIN when we attempted to lift the roof). Right now, we would just like to get the roof lifted so that we may have better/easier access to the lift system. But, alas, it won't even let us manually lift past a few inches before it hits that stopping point. PLEASE HELP. We are mechanically inclined and motivated. I just need some pointers, guidance and some moral support.

    Hi Sierra. Doesn't look like you got a response from anyone? I too have been hoping that some of these 2009 posters might still be active. I have a 92 Fleetwood cobra with nearly the identical chain/ spring lift system. Something broke and the front won't lift any more. I have it up on 2x4s and am going to start the repair soon. Did you ever get yours sorted? I'll keep your question in mind as I look over things. I have the schematics from Hanna RV which are more detailed then the camper manual. But this whole thing is a bit of a mystery to me.

    I'm hoping someone will see this, in this old resurrected thread. I have a 1992 Fleetwood 621. It has Fleetwood's chain/spring lift system. The back lifts fine, the clutch assemt works fine as it holds the rear in any position. But the front does not lift at all. While cranking, the "front" chain doesn't move, but there is tons of tension on the chain both top (upper tube) and bottom (lower tube). In the picture, the sprocket with the red arrow does not move. The sprocket with the green arrow moves like normal. In the manual, the part that doesn't move is listed as "#17 sprocket roll pin". I don't know much about sprockets, gears and roll pins, but I've read a few posts saying the roll pin broke. Is there just a roll pin pounded through the sprocket to keep it attached to the assembly? If so, it's likely the roll pin broke and the sprocket just sits there as the drive shaft is turned right?

    Hi everyone. I spent a great deal of time researching, looking over schematics and pondering this lift system and how it works. I was able to repair mine and am fairly confident in how the system operates now. If anyone else finds this thread down the road, please feel free to reach out. I took a bunch of pictures and made notes for future reference.

    @David Phillips so glad someone else has found this thread! I’ve been scouring the internet for anyone within the last few years still working on this problem. I just bought an 89 Rockwood XL and after an entire day of digging found that the drive shaft had completely snapped in half about 5” past the crank up front. I tried to patch it with a piece of pipe but it snapped the bolt in half (scary) and then with a stronger bold it snapped off the tip of the shaft that is connected to the sprocket. The back was stuck halfway up but I got it lowered with some vice grips and elbow grease. I’m guessing something is wrong that is making it so difficult for the back end to lift, but I have no idea where to begin with accessing the springs inside the metal housing. It appears the chain is on the sprockets. Any help you can offer would be greatly appreciated! C3495D91-1D05-4534-9426-0C4CEBABAFBE.jpeg 2B0BBF4B-BB45-4E8D-A412-C5888C5E9684.jpeg

    People of the world with chain lifts UNITE! Lol. Wow, I hate to say, that snapped drive shaft pic is a little awesome, in an unfortunate way. Two thoughts come to mind, first I wondered if your roof had a leak and has taken on excessive amounts of water? The foam in the roof holds water for extremely long periods of time and can get very heavy. Because the force of your cranking is directly related to the force needed to push the spring rods through the tubes and push up on the roof, maybe extra weight was to blame? But because you said you had to use vice grips to lower it, I suspect the problem is in the lifter tubes and the spring rods that are part of that system. Maybe even the rear chain. This system is extremely susceptible to corrosion, if water gets in around the lifter tubes, it just flows down into the push spring tubes and onto the chain. And I have no found an easy way to thoroughly lubricate the entire system. My guess is rusty or corroded parts in the rear part of this system is what's causing the issues.

    When you say you used vise grips to get the system down, how did you do this? Vice grips on rear drive shaft? If so, how much force did you need to do this and how did it "feel" going down?

    Thank goodness someone else is dealing with this stuff around the same time I am!
    So I did put the vice grips on the drive shaft and it was pretty difficult to lower it but it did get there.
    Today I dug back into it and with some serious will power I managed to replace the drive rod. It is holding up so far, however as it was going up I noticed some loud spring noises and when I looked at it the spring for the rear passenger side had completely doubled over and was stuck… this was after I had to cut some of the rotted flooring out and replace it because I realized that side was sagging and causing that post to slack.
    I have now ordered a new spring and tube that I found on pop up parts, but could be a bit before they come in.
    Now my issue is figuring out how to remove the posts and spring… any ideas?

    Rotten floors always seem to be connected with problems on these lifts, Newton's third law! As hard as you are pushing up on that roof, it's pushing down on the floor. And in those situations, that spring rods can bend in ways they shouldn't. And that might be the initial cause of all of your problems here. The only good thing is that you will have all new springs and tubes that you can maintain properly.
    I am sorry to say I don't have any advise on removal. Start by releasing tension on the chain at the rear end. Well... Start by removing all panels and fridges if your way... Then release tension on the chain system by pulling the tension bolts out of their bracket. Then start removing items as you can. Post pics and details for others as you go.

    As I understand it, the factory that produced these lifts burned to the ground along with all records of these lifts systems. After 30 years, the number of people who have knowledge of these systems are few and far between. So documenting and sharing everything you can is essential!

    Let me know what you find!

    Ok after a few more days of research (and body recovery... Man, that roof is heavy with the walls and crawling on the floor is hard on the back and knees.) I got confirmation that my new spring and tube are on the way and I'm ready to dig back in. When you say relieve the tension I'm not sure I have a full grasp on how that works. The bolts I believe you are talking about (red arrows in picture) weren't actually touching the plate when I opened up the cover so I don't know if someone has been in there already messing with it or what. There is also a metal flap (yellow arrow) that gives visual access to the spring where it transitions from the square pipe into the guide tube that appears to have been bent upward either by force or by a person. Should this be bent back down? See picture below. You can also see where the spring was completely doubled over. I was able to get it to retract using the crank though it was pretty hard to crank.
    Do I need to remove the lift post to access and replace the springs? I was initially thinking maybe I would but after further research I'm thinking maybe not...
