K member swap and upgrades. Bergman pins

If i have play on the LCA side, what do you suggest? I have seen folks run weld around here, but I left it until I got my pivots. Now that I have them (the pivots) I know they are a smidge longer and I have a little length to play with. I did make a mistake by welding on the LCA side previously and am a little shy to mess with it (LCA side) but I am open to suggestion. the driver side is tight.....the drinkers side has 1/32"+ of play...on the LCA side. Also, when welding the front side washer on there, how did you locate it to be center? I feel like putting the whole deal together and in the car with the torsion bar in place I could make sure it was easy in/out?

Thanks for the help.

EDIT: I see you have welded the LCA side in your pic. so front and back ....correct? wait, I re read the post....just on the back side. copy that. I wont change my post as it may add light to the situation.

When you inspect the pivot tube is there a place that is clearly worn or out of round? If there is then you can weld that area to add material. But you’ll have to either file it back to round (difficult to do accurately) or have it machined.

Your other option would be to replace the whole tube, but, you’d need a tube with the correct inner diameter which also might require machining to make it that way.

I’ve been fortunate not to have to do this repair yet, I wonder if @Jim Lusk has any other tricks or suggestions

When you get the weight of the car on them can you tighten them up further? Mine are at a point where they only tightened so much and the pins just spin in the Delrin.

You have to hold the pin from the backside to get them torqued properly, I honestly don’t think setting the car on its wheels will help the spinning situation since the bushings rotate on the pins when everything is assembled.

And I’m not sure you’re going to get the result you need anyway, if the shoulder of the pin is sitting flush against the pivot tube it’s not going to move any further to eliminate play. And you should be able to see that when you slide the pins in. Now, if there’s still a gap between the pivot shoulder and the tube it might tighten up a little more when the nut pulls the pin all the way forward

Don’t forget the the washer welded in is a great idea to fix an oblongs hole BUT it will affect caster. Sadly it is a great fix to save a worn out k frame.

It should not effect caster, the LCA bushing should still sit against the original pivot tube shoulder. The weld should go around the outside of the tube and not effect the mating surface.
