I have a 1964 C10 with a 3 on the tree column ****. The adjustment C clamp is maxed out in its slots but I still have too much gap between the lower shift arm and the shift Tee. What do I need to rebuild or replace to fix the issue? I have looked at posts showing how to tear the column down and put it back together, but I don’t know where my extra free play is coming from.
If proper adjustment cannot be made by adjusting the adjuster ring (lower bearing retainer) you may have to disassemble it to find the problem. Above the shift levers there is a spring and spacer, if I recall correctly the spacer is held in the proper position by tangs in the mast jacket. If that spacer is not in place it might make it impossible to adjust.
If the adjustment “C” shaped piece is maxed out, then perhaps the 3 small tangs in the mast jacket are missing or worn. If the tangs look ok, then adding a shim ABOVE the stop ring (above the large spring) will help. That would move the shift tube down a bit more.
Waylon, I looked over my pictures again. The shim(s) would actually go BELOW the big spring. The thin ring above the spring is merely a stop point for the spring. I’m not sure how I’d go about it. Perhaps making new tangs is a better idea. Please show us what solution you come up with.
If you look closely at this picture showing the bottom of the column, you can see a thin shim or two between the bearing and the lower shift arm. There’s a tiny piece of blue shop towel stuck to them. I think I might have put those shims in there. I vaguely remember working on it but it has been about 30 years. Maybe more shim there is what is needed. I think the shims are flattened out soda cans that were cut into split washers/shims. I either did it myself or someone told me that’s what I needed to do. I hate having a poor memory.
Adding a shim at #4 will push the lower bearing down and allow for additional adjustment. Adding a shim at 1, 2, or 3 will functionality draw the shift tube down inside the outer sleeve and also allow more lower bearing adjustment. You must decide if the problem is caused by worn or damaged sleeve tangs or other issues. Where to put the shim will become evident.
