Camping: Jurgens Classique
Good evening to all members,
This weekend I have given myself the job of fitting axle/chassis steel blocks to my older model Jurgens Classique in order to raise the van slightly. In order to do this I have to jack the van up high enough to be able to drop the axle down and slide the support blocks in on top of the axle support bracket. I have been looking at correct ways of jacking the van and have noticed that chassis jacking is not really an acceptable method. If I jack the van up on one side first under the axle until the wheels are clear of the floor, and then support the van on tressels under the chassis at front and back corners or rather about 600mm in from each end of the corners, and then do the opposite side in the same manner.....would this be acceptable without doing any damage to the chassis. Unfortunately I have to lift the van away from the axle to be able to access this point.
Any other alternative methods been done by someone who has done this job before.

Many thanks.

Steve.

As jy n pap wiel het ?? Wat maak jy dan.
Ek sou voorstel. Jack die van, sit die tressels in sit dan jou corner steadys in vir extra en doen dan die axle gedeelte.
Onthou om alles baie stadig te laat sak sodra jy klaar is. In reverse order.
Jack, steady's af, tressels uit en stadig laat sak tot wiele oppie grond is.

Steve, my view is jacking up the chassis only becomes a problem when jacking up the corners thereof because this cannot be done simultaneously and will result in twisting the chassis like koeksister. I suggest you remove the U-bolt on the one side and as close as possible to the axle, jack the chassis on this side up slightly, just enough to slip the spacer block in between the axle and the chassis. Drop the jack slowly to join the axle and the chassis with the spacer block in between and secure the new U-bolt. Therefore you do not need to lift the wheels off the floor. When jacked up, lower this side's corner steadies as a safety measure.

Do the same on the other side.

Steve, I hope I read you incorrectly: You are not intending using the steadies as jacks are you?  That is a quick way to do big damage.   As Oom Jeep mentioned, would the method used to replace wheels not be enough?  That is, first lower the front of the caravan as low as it can go.  Then crank out the back steadies to touch the ground.  Now lift up the front using the jockey wheel as high as it can do this.  Lower the front steadies.  If this is still not high enough, you can put something like planks of bricks under the jockey wheel and lift some more. Eventually the caravan should be standing on the four corner steadies, quite safe even without tressles.

Fred, if your procedure is followed, the wheels will be hanging in the air and how are you going to lower the heavy axle and two wheels and even more, how are you going to get it back ?  You will need two more people to assist in fitting the spacer and lifting the axcle with wheels.  I have fitted spacers to my son's Super Sport all by myself following the procedure as described in my comment above.

In addition, lifting a heavy caravan such as a Classique's full weight (not hinging on the axle as normal) with the jockey wheel is close to impossible.

Lennie, I would not argue with you on this.  I was able to lift my previous Supersport that way to work onderneath the van, but I accept it might not work with this much heavier caravan.  Perhaps you might do it by supporting the caravan on its steadies in the normal way and then removing the wheels by lifting them up with a jack. As far as the diffuculty of handling the heavy axeles go, a trolley jack might be of use.

Len met n hidroliese jack kan jy die as net genoeg laat sak om die spacers in te sit, vas te maak met nuwe boute en u-bolts en jy doen dit een vir een of as jy twee jacks het kan jy beide doen gelyk.
Ek wil net sê vir n ou wat nie baie handig is nie, is dit nogal n job en n half.
So-nie as jy nie kans sien nie, moet jy die joppie laat doen.

Johan toegegee, 'n trollie-jack sal die as kan laat sak en weer terug oplig, maar dan moet die karavan ook in die lug wees.  Dis mos nou baie makliker om die U-bolt los te maak terwyl die wiele nog op die grond staan, die karavaan op sy onderstel met 'n trollie-jack net 'n raps op te lig, die spacer in te skuif en die karavaan weer te laat sak met die trollie-jack, op die spacer en as.  Ek is so semi-handig en het dit 'n eenvoudige joppie met my seun se Super Sport gevind.

Stem saam. In my geval is my pens te groot om so laag te buk. Gevolglik lig ek die onderwerp hoër op om die oom te kan akkommodeer.
Jy sien hoe werk my kop. Hehehehe. Moet altyd dink hoe om myself te akkommodeer.

Steve based on what I'm reading you have no intention of lifting the caravan with the steadies.
I would suggest that it's better to place the tressels as close as possible to the axle pressing up against the main beam the axle is attached to, thereby minimising the reverse bending that the caravan chassis is subjected to. Probably also a good idea to lower the corner steadies to stop the caravan from titling.

Based on some of the above comment, loosening the ubolt first and the jacking the chassis as close as you can with a jack sounds like it will work.
Solving the weight issue of the axle? ...... Once you have the whole thing jacked up. Take of the wheel. Voilà 20kg lighter!

Chris, there is no axle weight issue to resolve, the wheels and axle stay on the floor untouched, it is only the chassis that must be lifted off the axle with a jack, ± 10cm depending on the size of the spacer.

What is the logic behind this?
I assume it will count as a modification so you will have to let your insurance company knows.
Technically there are too many challenges i.e. centre of gravity, bolts etc.

Have not done this so just a suggestion:
Chock the wheels both front and back on a hard level surface, maybe fit caravan to car to prevent turning and rolling off jack
Loosen off the u bolts on one side and place a jack on the spring as close to the axle as possible without getting in the way of spanners., new. u-bolts etc, and lift the spring off the axle and slide the spacer in, lower spring on to axle, fit new, longer u-bolts and tighten. repeat other side.
If the same as was done on cars, check the locating stud and hole on the new block/spacer are the correct size before trying to fit.

Hi to all the above members who responded to my enquiry on the above query I had regarding the lifting of my van.
Firstly thank you guys so very much for you input regarding the above...it really was appreciated.
The whole job was a total disaster due to me not noticing that the chassis was similar but not the same as my previous Sprite Super Sport, and I had based everything on my previous spacer block installation. The long and the short of this project is.....one can not install spacer blocks to a 1992 Jurgens Classique without doing modifications to the chassis drop plate that locates the axle!!!...well , i am assuming that all these models ( 1992 ) are the same and that my van is no different to other Classiques of that year. I will come back to everyone as to why this is the case when I have completed some drawings to indicate why. Also Lennie from Cape Town, would you be kind enough to supply me with your mobile or a contact number as I would like to chat to you....My contact number is: 0827098071.
Many thanks to all again, will chat again shortly.

Oh my goodness Steve !  -  then please ignore my recommendation.  I have done the spacer project on my son's 1992 Sprite Super Sport and that was really a simple job to do.  However, I would not fiddle with making changes to the chasis itself and would recommend that you rather obtain expert advice. (I am no expert in this regard).

Johan, lifting the chassis a few inches to a certain extent cures the problem of a rubber suspension zagging, it extends the life of the axle without having it replaced or reconditioned at a huge cost.

Barry, your recommendation agrees with mine, however, these caravans do not have springs but a rubber suspension.

Might it not be easier to fit aftermarket coil springs or airbags to either side to compensate for wear/sag?

Shu Lennie, somehow don't think so.....not sure how one could accomplish that without welding additional brackets to the axle and steel supports across the entire chassis to accommodate these coils...also the additional weight factor now creeps into play again!!....A bit of a catch 22 situation.

Steve, I would not attempt to go the coil spring route becauste then shocks also come into play.  I would prefer the spacer solution, however, alterations to the chassis should rather be done by Jurgens-agents.

If I remember correctly on how your caravan chassis looks like, it will not be possible to raise the caravan as you suggested and noted.  For this to be done is close to the redesign of that chassis as the whole of the caravan has to be raised of the chassis an not only a spacer between chassis and axle.  Due to the axle actually being part of the chasis.

I would look in the following aspects that may be a cause for your caravan riding low.

  • Rub-Axle is worn and needs replacement.
  • Weight of everything you packed inside the Van.

Please note that I only mention the weight due to own experience with the Penta's I had. They were always riding low comparred to my brothers Penta.  In the end I found it to be all the extra stuff I am packing. So it's just a point to concider.

I have recently added spacers to my Sprite Scenic. Just like oom Koos indicated I used a trolley jack to lower the axle just enough to fit the spacers with the wheels removed.

The one way I did not see mentioned was to use old style car ramps to support the chassis while working under it. The whole caravan was rock steady with the cross portion to the back of the axle resting on the car ramps. It was like having the axle on the chassis but only a bit further to the back.

I have to indicate a Sprite is much easier to get the longer bolts in than on a Gypsey. This is on the non modular or ladder chassis.

Google "Vastrap Karavaan Produkte". Hulle het basies wat jy soek vir jou dubbel as wa.
