'66 floor shift column reassembly

Need some help please.

We pulled the stock column thinking we would install an IDIDIT, but didn't. Next, we disassembled the upper part of the column, but I had purchased the wrong parts, and it sat for a month. I've now attempted to reassemble, and something is wrong. From reading the assembly manual, I thought it would be simple to use the "nipple" on the column support to position the column, add the lower housing with the wiring harness through, then the upper portion of the column, and screw everything together.
The upper cup ends up roughly 60 degrees counter clockwise to where I think it should be, based on the turn signal handle position. I've tried to turn things to fit, however when I do, the lower portion of the column with the "trough" no longer lines up with the support bracket.
Any advice?
Also, the upper portion of the column sits flush until i screw the turn signal switch in, and then it moves away from the lower portion by roughly 3/8", and I don't believe that is correct either?
Any thoughts appreciated.
Greg

Re: '66 floor shift column reassembly

Greg S,

Is your column a tilt or non-tilt column? I'm assuming "not." I don't know if it makes a difference for your problem, but my reply may help by just bumping your question up towards the top.

Re: '66 floor shift column reassembly

If the column position is correct, then I would think the cup position is wrong.
Doesn't the cup screw to the lower section?
It has been a couple years since mine was apart but I dont remember
having any issues. A closer picture in there may jog a memory...maybe.

Re: '66 floor shift column reassembly

No, the turn signal switch has three screws that go into the upper column, and that seems to hold everything together. Taking parts apart and seeing what is forcing the cup up has led me to believe its actually the lower part, F in the assembly manual, that is too high, not allowing both the upper cup and signal switch to go down toward the firewall far enough, and this forces everything else out of place.

Re: '66 floor shift column reassembly

I don't think you need to worry about where the trough sits in the column mount bracket. I just had a 67 column apart and it only went back together one way. Loosen the dash bracket, rotate the column to where it needs to be and see what you have there. I think you are close.

Re: '66 floor shift column reassembly

If I'm understanding your issue correctly, you could give this a try.

1. Install the lower mast jacket in the correct position.
2. Loosely assemble the upper bowl assembly w/ the 3 screws, springs, locking plate and, T/S switch.
3. Slide the upper bowl onto the mast jacket until the locking plate slips into the slots at the top.
4. Rotate the bowl until you have the T/S handle positioned at the 9 O'clock position. The locking plate will retain the bowl assembly to the top of the mast jacket.
5. Tighten the screws.

Thanks!
That worked great, except the top is together, and secure. The lower mast jacket is hanging 1/4" below the upper assembly, loose and swiveling.

Re: '66 floor shift column reassembly

Looking in your AIM,do you have all the correct parts for the column? I've rebuilt a couple of "66" floor shift columns and using the AIM have had no issues. I can tell you that the special washer and the rubber washer that goes against it are very important. The column only goes together one way correctly with all the parts shown in the AIM.

Thanks,
I had all the correct parts, however I didn't realize the lower metal washer, which apparently holds the lower outer mast "up", had come loose and fallen down the inner shaft, past the tang it should have pushed against. Reassembled everything without dropping anything down the shaft, and it worked like a charm!
