 Posted: Mon Mar 30, 2015 11:49 am Post subject: Link Pin Front End Issues |
 |
|
I am restoring a 1958 Euro Ragtop and am having some issues with the front end. A little background; the car came with a 1960 front beam with 1960 trailing arms. Later I located a 58 beam and used the later trailing arms. I am in the process of installing the rebuilt spindles. On the passenger side I measured 8mm offset and shimmed accordingly, on the drivers side I measure 5mm which is out of spec. I see no damage to the trailing arms.
Is there any way to determine where the problem is? Any help would be awesome!
Thanks
Bruce

if you are sure its an early beam 5 mm is in spec

Actually using the later arms that take the dust shields the spec is 5.5mm minimum. I finally did solve the issue by removing the upper torsion bar assembly and turning it end for end. After re-installing the arms everything was in the 6mm to 6.5mm range.
Is there a left and right side for the torsion arms?

Arms can be swapped side to side.
Sometimes on in install such as yours it's simply a matter of the grub screws not seating properly. I have seen them where you slip the arm off and slip it back on and it's suddenly back in the range of the chart.
I'm not sure exactly when the change came to the trailing arms for the dust cap and O-Rings. My 60 still had flat faced arms. So if your 60 arms are flat faced as well, they should be the same as the 58's I think.

drscope: I believe you hit the nail on the head. By swapping the leaves end for end it slightly changed the geometry enough to bring things into spec. It could just be how the detents are drilled into the bars or how the grub screws set in. My trailing arms have the recess for the dust shields so they use the 8 shim stack instead of 10 shims.
Thanks for the help, I was really stuck on this for a while!

Those differences you found is the reason for the shims. They help square up the link pin carrier to the trailing arms regardless of the offset in the arm faces.

sorry to but in. but 'Im having the same problem. after reading this I realize I have the arms without the recess for the dust shields. So I believe I need to go with the 10 shim set up. I have an offset of 5.5 on one side and 6mm on the other. The problem I have is, I have the big book thats from 1961 to 1965, and it only shows the 8 shim chart with the dust covers.
does anybody have the chart for the older car? Or do I just shim to fill the gaps.
This is a pic of what I have now when I was trying it with the dust covers. There's a good size gap at the bottom. Thanks
