How to get the blinker switch assembly out of a
1966 Olds 98?
It's been a while, so bear with me. The main objective is to remove the steering wheel, to have access to the turn signal switch.
1.Negative battery cable disconnected
2.I believe you twist the horn button in the middle of the steering wheel, and pull up, to remove. The horn button should have a ring of thick rubber on the bottom, which keeps it in the steering wheel. The chrome piece under the horn button may come off with it, or it stays on the steering wheel. This is the part that is fuzzy to remember.
3.Remove the steering wheel nut, and lock washer.
4.If you do not have a steering wheel puller, go to your nearest auto parts store, and see if one is available to rent. The cost of this puller is relatively low, so you may just want to go ahead, and purchase one. While you're there you need to obtain another tool also. Steering Wheel Lock Plate Tool.
5.After the horn button is removed, and the steering wheel nut, you will see a flat metal area of the steering wheel. On each side of the threaded part of the steering column shaft, there are two small threaded holes, in this flat metal area.
The steering wheel puller, is a bar shaped piece of metal, that has a threaded hole in the middle. There is a threaded shaft that goes into this hole. On each end of the metal bar are slots. Threaded bolts go through these slots, and line up with the two threaded holes in the steering wheel. There is a pointed tip, that rotates on the threaded shaft, of the steering wheel puller. This pointed tip goes in the middle of the steering wheel shaft. (The shaft that you removed the nut from)
Find the two correct threaded bolts in the steering wheel puller kit, that matches the threads in the steering wheel holes. They HAVE to be the correct size, AND the correct thread. (Fine thread, or Coarse thread. They will be SAE thread, and not Metric) If the puller does not come with bolts, or the correct bolts, you'll have to purchase them separately.
Place the puller on top of the steering wheel shaft. Run the threaded shaft of the puller down, until at least 3 to 4 threads of the shaft, are showing on the steering wheel side. Now place a threaded bolt in the slot on the outside part of the bar.
Run the bolt down into the steering wheel threaded hole on one side. Make sure it goes in at least 1/2 inch. Do the same with the threaded bolt for the other side.
Adjust the length of the threaded shaft of the puller, so that the two outside bolts will go in as advised. Adjust the threaded shaft out, or in. Be SURE the two threaded bolts, are threaded down into the steering wheel the same depth, and the bolts are the same length!
Now turn the threaded shaft of the steering wheel puller in, with a ratchet and socket, to remove the steering wheel. (Turn the shaft to the Right)
6.Now remove the steering wheel lock ring. The steering wheel lock ring tool is now used.
There is a cylindrical shaped piece that has threads on the inside of it, and has a hole at the top, that a lock pin slides through, for the above tool. This cylindrical shaped piece is threaded down onto the steering wheel shaft.
The tool has a handle shaped like a screwdriver handle, and a shaft attached to the handle. The shaft goes down into the cylindrical shaped piece. Then the lock pin goes through the cylindrical shaped piece, and also a hole in the shaft of the tool. This lock pin locks the cylindrical shaped piece to the shaft of the tool.
BEFORE the cylindrical shaped piece is pinned to the shaft, you slide a U shaped piece up on the shaft. (Thought it would be better to explain it this way)
The opening of the U, goes down towards the steering wheel. It's U shaped to clear the steering wheel shaft.
As you turn the handle of the tool to the right, it pushes the U shaped piece down. The U shaped piece then depresses the steering wheel lock ring down.
(There is a Thick metal spring under the steering wheel lock ring)
You have to take a metal pick, and a small flat tip screwdriver, and remove the round snap ring. May take a little finesse, and a few tries. Use patience. Now back the steering wheel lock ring tool off. (Turn to the Left) The steering wheel lock ring will come up, so that you can take it off. Remove the spring. Remove the plastic horn contact assembly. Now you can see the screws to remove the turn signal switch.
