Re: Very Basic Off-road Ball-Joint Beam rebuild

Post by Ol'fogasaurus »

Since this is supposed to be a basic off-road ball-joint beam build I am supposing that those looking at this for information has not done anything like this before (I being one of them) and those who look and snicker are planning on being helpful I decided to go into more detail on this part as I think the instructions are often kind of confusing.

On the last installment (good lord, it was only yesterday not weeks and month like before) I had cut a 2” section out of the middle of the upper torsion tube of the brutalized stock beam.

Image

Image

Image

These three photos are what the offensive section of the torsion tube looks like just in case anyone wonders. I found it fascinating in a destructive sort of way.

Image

This is what the adjuster looks like coming off the card. Pretty little thing that breaks down as follows:

Image

This is the outside portion of the adjuster exposed and…

Image

This is the center piece removed for some changes to be made.

Image

There are two threaded holes in the center section, one is filled with a threaded plug and the other one is where the adjuster threads into. Using a 6mm Allen Wrench you remove the plug from one hole and move it to the other hole. The top must be flush with the top of the center section so that the center section will slide into the body of the adjuster.

Image

In this picture you can see both holes. Inside of the U-shaped part of the housing there is a slot and in this slot the open hole of the center section should be seen. When reinstalling the parts, the adjuster block is placed over the hole with the pointed set screw w/nut is slid down the hole in the adjuster block and the adjuster screw is threaded into the center section (it is called the disc on the Bugpack instructions and the Sway-a-way calls it the adjuster.. I think). The Sway-A-Way does not seem to have the short plug so other than not using the wrong threaded hole in the center section, it probably may be eliminated; I left mine in place but before I go too far with the welding I will slide the spring pack into the adjuster to see if it causes a problem.

Image

When reassembled, the gap in the center section should be sitting like this if you are going to do a King and Link beam.

Image

This is the setting for a ball-joint beam.

Now comes the fun part: setting the adjuster itself before installing it in the beam.

Image

Image

In this shot you see part of the slot in the housing that allows a certain amount of movement of the block, hence the spring pack. First, let me say that the second line I was so worried about that I laid in on the last post, while its dimensions are important they are not fanatically important (see, after having done it once then the instructions are clearer now… isn’t that the way it usually is? I think that is why they say it should be done by an expert [an expert is someone who was a “pert” or “spert”, I am not sure of the name so I have given both, but has gone through therapy and is not one anymore]) as there is some finagling with the settings you can do. First of all, the second line is to be the centerline of the adjusting bolt and no, it is not easy to mark the line where you want it on the housing; it is not that critical.

You can set the adjuster to allow you to lift up the front of the car only or drop the front end of the car only or to do both; I have chosen to do both. In this picture, the adjuster is set to allow the car to be lowered (or vice-versa). At the full down setting I made two little tick marks at the front of the adjusting block on the housing.

Image

In this shot, I adjusted the block fully in the other direction and again, made two marks.

Image

To be able to raise and lower I moved the adjusting block halfway between them and locked the block down so it wouldn’t move using the set-screw and its locking nut.

Image

This shows it with the other lock in place.

Image

Then, believe it or not, I tacked the adjuster in place using more than enough tacks to keep thing solid when moving the beam around.

Edit: I did not mention that the adjusters are tacked in place only for right now as the torsion springs must be installed to check for alignment and proper location of the locking dimples for the trailing arms. I also failed to note that the locking screw that goes though the adjuster block and into the center section to lock the spring stack in place should only be into the center section far enough to hold the center section in place but not far enough to stop the spring stack from passing though.

If you don’t get the locking screw in deep enough to hold the center section in place you could push it out of the adjuster housing and then you are in deep doo-doo and will have to cut the whole thing apart (as far as I know which seems to me to be correct).

When sliding the spring stack though the center section you have to keep the leading ends of the splines together somehow. Methods I have heard used are both good and bad but you can’t very well tie or tape the leading end of the stack together as the fit is too tight through the center section. Super gluing the ends of the splines together, for a very short distance, sounds OK as long as that part of the stack is very clean so it will hold. Running a tack weld is probably not a good idea because of the heat but I have heard of it being done… I don’t recommend it.

Once everything is checked out then you should be able to finish weld the adjuster in place. If you leave the spring stack in place then remember not to get too much heat into the tube/adjuster block to ruin the individual splines.


Now on to the lower beam and it should be done unless someone has any other bright ideas.

This might receive some editing as I expect some comments. Thanks for reading this; I do expect to post pictures of the finished product.

shouldn't you completely weld it in place before you cut the lower tube? just a thought on my part....

:lol: I will. Ran out of time and back :roll: :wink: You have to put the springs in place to check for alignment before you go to all the work of welding it up.

Thanks Herb, I forgot to mention that.

Herb, I did an edit to reflect additions of information based on your question which showed how tired I was as covering the welding was intended to be in there. As I was building and taking pictures I was also covering what I wanted to say. Thanks for asking the question as it was very important to cover that part of the installation. I am sure that this subject post is not complete as I am hoping for some additional input/feedback in on this.

Lessons learned on adding the adjusters: when I decided to then built the jig, I had no idea of how thick the beam’s material was so it probably wasn’t necessary but, on the other hand, it did make it easier for some parts of the job including taking pictures. By doing one side then the other, each beam side does support the other side during the modification so one could easily do this without the jig but it did make some things easier at times (mostly not having to fight with the beam and it’s sliding around or positioning) and gives some piece of mind. I think if I was going to do more of these conversions (I have a king and link to do) I would make a holding jig but this time, I would align and make the legs to fit into the holes in the work bench. I have seen pictures of people building one a big floor vice but I think those may have been for beams without the mounts to the frame heads.

I had both the Bugpack and the Sway-a-way instructions to compare and go by but it wasn’t until I was just about done that some of the instructions started to make sense. They tried to cover too much in one set of instructions and I think they got lost at times (I know I sure did), that and the pictures had been reduced too much or were confusing as they tried to cover K&L and BJ in the same production illustration (PI). I have had to write instructions like this and it is so easy to miss information when writing them after the fact or… if you know the subject too well.

If the springs are slightly greasy, I had good luck using a rubber band to hold the pack together. Once it hits the adjuster, it slides off as the springs slide through.

Good idea. :)

Another way I heard is to pull one of the large center leaves back so that the rest will bunch down and enter the center section then, when through the hole, you push the center leave back into place. Never tried it but it sound like it should work... yea right with my luck! :roll: :wink:

P/R tube seal works real good as well.

Another trick to fit the springs onto the arm, and through the center unit; I tape them as tight as possible with three to 4 wraps of electrical tape. Then I hit the end of the pack edges with a 3m scotch bright pad in an angle grinder. Just enough to round off/ debur/ chamfer the ends. It helps a great deal.

I just used a zip tie to hold them together.

I gather that the zip-ties, tape, and other stuff just pushes back and stays there?

I meant to mention (if I hadn't already) that both the Sway-a-way and the Bugpack mentioned that you could install the adjuster on only one front beam tube. I am assuming that is a way to soften up the suspension on a buggy or a rail where there is less weight on the front end; set the adjuster to a different/higher setting than the other non-adjustable tube and allow the adjusted springs to come into full play at more travel than they would at a stock setting. This would mean that you don't have to cut, break or remove splines to soften up the ride on your buggy or rail. This could also be accomplished by having adjusters on both tubes and setting them differently.

I have used all these methods to hold the leaves together and they all seem to work. I have found at times it helps to keep one of the center leave back slightly to help on getting them through the center.
I adjust the top torsion leaves a couple turns more than the bottom one on our 9 car. I understand it helps keep the upper ball joints seated in the spindle.

Whatever you do, make sure the end dimples are facing the right way. Driver's side, up and towards the back, passenger's side, front and down. I just had to do mine twice for lack of paying attention to that little detail.
