Torsion Bar install - File Splines or Keyway?

Postby thebranded » September 28th, 2013, 11:13 am

So finally found a junkyard teg i could practice on and have worked out how to remove the torsion bars too a level im happy to do to my teg.

The issue i have now is should i file down the spline on the tbar or file the keyway on the tubes?

Is there a benefit on which option i take?

Tubes are keyed on both ends, if i file the tbar, how do i know which spline to grind down, is there a #1 spline i can count from that is lined up tot he other end #1?

I'm leaning to filing the tbars simple so i can have it all done prior to taking the old tbars out.

great thx Mike, when you filed the spline how did you know which spline onthe other end to grind down as well? did you grind both ends?

What i'm worried about is grinding spline #1 on the front end and spline #20 instead of #19 on the other end, this would mean i would have to re install the tbars with a bit of tension on then either + or - to get them in.

What I did was remove the keyway on the torsion tube. Then I removed a spline on the front of the torsion bar. That way you don't have to remove the front arm. It will only fit in the front arm one way but you will have adjustability in the torsion tube.

great idea! that sounds like the best best of both worlds. I think i'll go down the same path.

[edit]

ok so ground down the front of the tbars, first tried a dremel and it didnt get far, so just used an angle grinder.

How strong are the tbar tubes? Cause only tool i have that can get inside it is a dremel...

I filed the tbar tube out using a triangle file by hand - with the front spline left that in place and basically pushed the control arm up and then fitted the tbar tube on at the height that I wanted so no need to adjust the front.

I used a triangle file on the torsion tube as well. They're not too spendy. A dremel might work with the right attachment. Just try not to go too deep.

Wohoo, another aussie, looks like we have 4 active members now!

Triangle file sounds like the way to go, i got to find a file now, My tool box is finally gettign filled!

Also since im takeing my time doing this i'm trying to document each step. Below is how far i have grinded the front of the tbars.

Only one end necessary. Guess you already knew that. :)
If you have to "hammer" them into the tubes use something soft between the bar and the hammer like a board of wood or something made of rubber, I hammered straight on the bar and small cracks appeared :S

Yep, so although the stock bars are keyed on both ends, and i was originally going to file down both ends, but with the suggestions to grind one end of the bar (front) and the rear tubes instead i think that should be easier.

I dont expect to hammer them at all, when i removed the ones inthe junkyard teg (for practice) once all the tension was removed from the bars, they slide in and out with just a push from my fingers. But certianly if i need to persude them in i will use a wood block, thx.

Lube them up real good too. It'll ease installation and keep the bars from rusting.

ok so the day started good, all set to swap out the tbars. i didn't get far...

I've removed all tension on the bars but they are rusted in. How do i get rid of the rust?

Just hammer it till it breaks free? The front look ok, the grease is still wet, but the rear the grease is gone.

I've sprayed it with WD40 for now, and just letting it soak in.

Get some real penetrating oil like PBlaster or Kroil and let it soak. Then put a punch in the little indentation at the end of the bar and wail on it. Don't hit the bar itself with the hammer or it will mushroom.
If you know anyone with air tools an air hammer will knock it right out.

Really?? Bummer! You may want to ask some of the parts stores what they'd recommend as an alternative. I know Kano will ship Kroil. Just unsure if they'll ship it overseas cheaply.
If you don't plan on reusing the bars you might try heating it up a bit.

BTW, you did remove the snap ring underneath the torsion tube cap?

There are a few alternatives, but i figure if i can get the right stuff, i might as well wait for it. Plan to tackle this again not this weekend but the following.

I don’t plan to use them again, but at the same time I don’t want to compromise them.

That would be the front ring, I was not even able to get to them. below is my rusted in bars, In the pic the ring is still on, but I have removed the rear clip, which was also rusted in, but the bars are held tight to the tubes.

Do you have the radius arm unbolted from the lower arm? It will keep tension on the torsion bar if it isn't.
Other than that soak it in penetrating fluid, get a punch and a big hammer.

yep, radius arm unbolted and adjustment nut removed.

Was worried about just hammering it out as in mike's link, he poped the front arm out.

btw been taking lots of pics, since i wanted to complie all of them into a "guide" of sorts

An air hammer with a conical bit will pop it out in seconds.
