    It's a 2005 Coachman/Viking with the recalled lift system. It's not broken....I just want to know if there are places anywhere in the entire mechanism that need to be lubed like, the lift spring tubes. I noticed mine has a small hole right at the turn (on all 4 tubes) heading for the drive box that was the recall problem. Is the hole a grease port? Anybody have info on what the dealers do to lube/maintain the tube springs and the entire system...or maybe even where I can get a service manual? I have spent a ton of time trying to find some info about the above but come up empty. Any info/links etc would be appreciated.

    Mike,

    Here is some info that I received the other day. I have a 2005 Epic and "thought" I would have to lube the lift system, but when I emailed Goshen they said that my model didn't have the Zerk fittings. I then emailed Viking's main office and asked them about my lift system and if it needed to be lubed. They replied that my lift system did not need to be lubed. It is selfcontained. Good luck.
    Oh one thing to look for if your crank is located at the rear of the PUP...take a look at the small tube that goes from your bottom sprocket to the Master Tube. The tube is about 18 inches long. Anyways mine mushroomed on the end that fits the bottom sprocket.

    The Goshen Lift system The Goshen lift system is used by most of the pop up vehicle manufacturers. The cable is connected to a distribution block, enclosed in a tube running front to back under the vehicle frame. Within the tube is located a simple mechanism that utilizes one pulley to push four heavy duty springs through tubes routed to each corner of the trailer. As the springs are pushed through the tubes, the corners of the roof are pushed to the open position. The springs are maintained in a straight pushing position by square telescoping tubes that extend as the roof is raised to the full open position. MAINTENANCE: There are two grease fittings located on the main assembly tube: one is located on the bottom side, toward the hitch end of the vehicle, and the second is located on the top side toward the rear of the vehicle. At the beginning of each season use a grease gun and add grease to each end of the tube until grease appears around the cable (approximately 6-oz). There are four small tubes coming from the ends of the main assembly tube to each corner of the vehicle that encloses the lifting springs. Use a needle grease gun adapter and add a small amount of grease in the hole at the end that curves up to meet the bottom of the square telescoping tube assembly.

    Tom....Just read this post. I don't think we have the same one.You mentioned "grease around the cable". I don't have cables anywhere. I looked for zerk fittings and holes all over the place and the only holes I have are in the aluminum tubes just before the bends turning upward at each corner. The push/pull springs are in the tubes, right? Check your private messages for more.

    3rdtimer i have a 2005 coachman/viking clipper 1265 st the holes in the spring tubes or for puting grease in to grease the springs. you well need a neddle grease adapter for your grease gun. on the master tube there is no grease fittings. it is selfcontained. and my did have the recall done it to. i hpr this helps. and on the chain you can use a little oil.

    Big Dad....Aha! Just what I suspected. I didn't want to start shoving grease in there only to find out that's not what they are for. I appreciate your quick reply.<img src=../Images/icons/icon_smile_approve.gif border=0 align=middle alt="Approve">

    I have a Goshen system and when I emailed them about lubing it they made no mention of putting grease into the holes on the bends. I suspect those are to allow any water that gets into the system to drain out.

    Gary....You know,I still think that's what the holes are for. Big Dad's assesment of the holes makes sense too, when you think about it. Now I'm really confused. Maybe I can get a dealer's service department to tell me. If I find out I will post their answer here.Stay tuned.

    THIMC----I just got off the phone with Connie up at Viking(nice lady).She told me that when the lift system was originaly installed at the factory that they did grease the lift springs inside the tubes in question. However, the holes in each tube are not grease holes. She didn't say why they are there but then again, she did say that there are no grease fittings on that system. Me? I think they can be used as grease holes. If I were going to do this, I would put some grease in, raise the roof a little, put some grease in,raise the roof a little,and again and again until the roof was all the way up. Starting with the roof all the way up might jam grease into the lift box and really create problems......as if the IDT system didn't have enough problems already. BTW....in conversation she mentioned that the recall fix was to install an additional brake mechanism on the shaft from the crank position.I have heard it makes it harder to crank up and down. Oh well.

    Hi guys.
    I have been stuggling with this lift system since I got my trailer. I purchased it 2nd hand, from the origional owner who said he had the springs and master tube (they both come together) replaced by the service dept. where he got the trailer. He even produced the reciept, noting the warrentee work.
    Well I phoned Viking the other day, gave them the VIN and asked a few pointed questions. It seems that Viking has no record of this on file. Therefore I am back at square one .. but with a little more knowledge .. and who to stay away from when I need to take the trailer into service.
    Anyways ... I asked the reps at Viking to send me all they had on the lift system, and that they did. What I got was a nice little booklet outlining the complete rip-out and install of all the parts, including the mastertube and springs and some techniqual bulletins concerning the cranker in the back, to issues with the hole in the frame rubbing against the anxle in the mastertube, causing the mastertube to bend and fail ...with of course the fixes ..

    I can answer any questions with this document, if you wish .. and will check back later if any arise.

    D-mo.....Does your Coachman 1057 have the "waist high" crank system with the IDT lifting box? I am just trying to clarify that we have the same lift system. If you have drawings from Viking I sure would like to get a copy of everything you have! Are we both on the same page?

    D-Mo,

    Could you scan the info book Viking sent you and email it to the site here? I'm sure they would post it in the manual section. Then everyone would have access to it.

    D-mo,
    I just got off the phone with Viking (Paula) who told me they didn't have any info about the lift system they could send me. I just bought a 2005 Clipper Spirit 1007 from the original owner who told me the popping I hear when I crank it up is from the new brake they installed from the recall. Paula said they discontinued using this system because of the trouble they had with it and that there shouldn't be a popping noise or any binding in the crank. My roof lifts, but there is quite a bit of noise coming from just inside the wall of the camper at crank height. Is there anything in your literature about a bearing or crank noise?

    If you could scan that info and get it on the site that would be great.

    Wayne....If you are getting noises at the waist high crank, pull the white cover off and start cranking it up. Watch the chain and see if it is trying to "climb" over the sprocket either at the top or at the bottom. If it is, I'm betting the noise is one of the links slamming down into the "valley" in the sprocket between the teeth. Typically,chains under those conditions get so loaded up they pop like a rubber band being released after a maximum stretch. There isn't much to the chain drive mechanism so it should be easy to spot. If the chain is climbing, it is stretched. Replace it with #35 roller chain. As I recall, there isn't much in the way of bearings in there so I doubt that's what the noise is.
    Let us know what you think.

    Mike, you nailed it. I've looked at this thing several times and missed it. It's happening on the bottom sprocket. I'll pick up a new chain and see where it goes from there. Thanks again.

    Hey guys:
    Yep my clipper has the waist high cranking system. There are four issues with this system that I have noted from the info. that I have been sent.
    1. trailers made before a certain date do not have a extra support built into the bumper, close to the cranker, which causes flex in the bumper, which may cause problems.
    2. Viking had two retro fits to the cranker/chain bracket. The first one is a one piece unit, the secound is a two peice unit, that is expandable to adjust for chain streach, but not thick enough metal, and the third is the primo - and expandable thick metal chain/cranker bracket. Wayne perhaps you should look at this bracket and see which one you have.
    3. Extra support for the cranking system against the wall of the trailer. There are instuctions on how to install two more lag bolts to shore up the cranking bracket to the back of the trailer.
    Right now I have four, they are now calling for 6.
    4. As stated earlier in my 1st post ... the hole through the back frame, which is not big enough/or I think not precision drilled which causes the system to rub against it and warp the screw drive in the mastertube. Im thinking that is where my problem lies.

    I hope this helps .. I will try to get this stuff scanned (somehow) and post it up here in the next few days.

    D-mo,
    My pup was manufactured Nov 2004 so I'm guess its got the old bracket. There aren't any adjustments on it. I'm going to take a link out and add a half link to my chain to try to make it work. Do you know if there is a diagram of the primo bracket somewhere. I'd like to get one of those.

    Wayne....Glad I could help. Assuming the chain has the correct number of links, be sure to count the number of links in order to end up with the correct length. The overall condition of the sprockets,shafts and bearing surfaces should be confirmed as not contributing to the problem as well. If all those things are ok, a new chain should solve the problem. Facing the back of the camper, the "slack side" of the chain is on the right.If there is an uncomfortable amount of slack when cranking it up, consider installing an idler sprocket like I did. If you want to do that, post here and I can provide you with good info on how to fabricate and install one. It's not that hard.

    Let me know.

    Hello All,
    I had a slightly shorter link (that still fits the sprocket) put in place of another one and that seems to have done the trick (6 bucks). There's no more slack in the chain and no more popping.

    Mike, I'm sure this'll happen again at some point and it might help someone else too so you should go ahead and post your idler sprocket info. I'd like to know how to do it.

    Thanks everybody that contributed to this, you saved me a big headache.

    Wayne....It occured to me after that post that a 1/2 link might do the job, but you beat me to it. Glad to hear all is well. I will try to post the idler sprocket thing soon. Right now the dinner bell is ringing. Later.

    Gwwcpa: Sorry there is no diagram of the "primo" bracket .. just an explaination of the different brackets in the question/answer page of the papers that I was sent. Again tho .. this is expandable and retractable, I would be contacting Viking for a replacement part.
    Right now all this information is at my local RV shop so they can do a proper install of the new system. Once its returned, I will post it to your board ..
