620 torsion bar questions (installation)

[motavated]

Seems like the torsion bars are unique to both the left and right side. What I need to know is how are they installed? I will try to post pics on later on what I am talking about. But pretty much it is stamped on the side of the torsion bar on which way it is supposed to flex. Not sure if the stamped side goes towards the control arm or the adjustment bar. Thanks!

 

tried looking for pics and answers. No solutions..

the claw of the torsion bar will face down an yowards centerline

^ what? I tried to read your message but i could not understand. I am going to take pics...

Stamped on the end if L or Right side. Can only fit one way so shouldn't be hard to figure which way it twists.

How to Reindex Torsion Bars

in front of the middle crossmember, you pull the boot forward to reviel the lock ring



Work a thin screwdriver into the edge of the ring. It will be tight. I had to work the angle back and forth while occasionally tapping the back of the handle with a hammer



Once you get under the ring, work it out slightly. Do not pull the screwdriver away or the ring will pop back on
 

After you have worked it off part way, use some pliers to pull the ring off the rest of the way. Be sure to still keep the screwdriver under the lock ring
 

Tap the rear arm of that holds the adjuster bolt out of the crossmember. Hang onto the torsion bar. It can slide out at either end. I was able to feel the splines in the end of the bar and I moved it two notches. edit:(but you only want to move it one notch!) The reindexed bar is on the right.



after the bar is reindexed, just hold the lock ring up and hit the back of the ring with a hammer. It pops on real easy. Put the dust boot back

just remove the anchor bolts then remove the nut on the A arm up front almost off then pound it out w/o hurting the threads
me and Icehouse did his 521 truck. We NEVER removed the c clip from the back
we just pulled the torsion bar from the front A arm and reindexed it there. Had to jack up the wheel to get it to reinstall. We never wanted to take the c clip out.

One of the rods was flipped around. Both rods where in the right side. Left was on left and right was on right. But the stamped part that is pictured was flipped.

My guess is the side that is stamped goes on the adjustment arm and the blank sides goes on the control arm. Can anyone verify?

[datzenmike]

I would say the top picture with the L and the arrow, would go on the left side LCA. In this position thecontrol arm flexes the torsion bar in the direction of thearrow. The blank end goes to the anchor in back. I'll check when I get home.
