Re: Rag Joint

Up until 1976 the power steering gear input shaft was 13/16 inch diameter. All manual gears were 3/4 inch diameter. In 1977 the power gear input shaft was changed to 3/4 diameter.

So if you have a car with the old style power gear (one with the 13/16 input shaft) the 7828871 flexible coupling is the correct GM part number. I do not find that part number on the GMPartsDirect websight. So I don't think that GM dealers carry it any longer. But is seems to be available at http://www.oldmusclecars.com/

If the flange on the flexible coupling has a flat, it will only install one way on the gear.

However, if the flexible coupling does not have a flat, the flexible coupling will install on any of the 36 serrations on the gear input shaft. You will need to follow these instructions in order to install it correctly:

Set the gear exactly on the center of its pitman shaft sweep (count total revolutions of the input shaft - full lock to full lock; then come back from full lock exactly 1/2 the number of total revolutions.) Then with the gear exactly on center, you will need to install the flexible coupling with the stop pins at 6 and 12 o'clock. The head of the attaching pinch bolt should be pointing straight up, passing through the 9 o'clock quadrant.

Re: Rag Joint

The screen that is molded into the face of the flexible coupling disc is for electrical continuity. With just a plain rubber disc, the flexible coupling may cause the steering column to be electrically isolated from the rest of the car. If this happens, you will not be able to blow your horn. Early flexible couplings (up until the early 1970s) had a brass strip or a wire that was installed around the center of the flexible coupling. This was a ground strap or wire that enabled a ground path to exist from the steering column shaft down through the flexible coupling, then down through the steering gear into the frame.

Starting in the early 1970s the screen was introduced. It did not add any durability to the rubber disc. It was a more reliable ground path for you to be able to blow your horn.

I know Jim, we've went through this before, but I'm here to say, my rubber washer is as tough as a steel-belted tire tread!!

Jim, Thanks. I was just trying to figure out how to re-install the ground strap when I decided to come search the forum. My new rag joint does have the steel mesh, so I guess I'm good to go.

Re: Rag Joint

It does seem tough, but man those wires tear up your hands. It didn't exactly "slip" on the spline and trying to work it on it's hard to avoid the wires. Ouch.
