CPP power steering conversion questions

Sorry for more questions on this but I didn't see this covered in other threads and CPP tech is not available on weekends. I'm trying to finish this up on my 66 stepside.

I need to cut down the length of the double d shaft but there is no mention as to how far it should slide fit down into the intermediate shaft mounted to the rag joint/gear box. Also, I've never changed out power steering lines before. Do I need to use some type of thread sealer or loctite on the hose end fittings to the steering gearbox and the one to the pump?

Re: CPP power steering conversion questions

I just measured and cut my steering shaft so that it was seated as far as it could be. I measured five time, cut it too long on purpose, and test fit. That's just how I did it, not wrong or right.

For the power steering lines they should be good without anything. They are flared so they should seal when tight.

Re: CPP power steering conversion questions

I thought the double d shaft was only supposed to slide into the intermediate shaft a little bit (couple of inches? Not sure) so in the event of a crash it will slide forward to allow for a "collapsing" effect. My instructions from CPP don't address it and I'm pairing it with a new ididit tilt column.

Re: CPP power steering conversion questions

You can figure B on this link and get and idea of how far it's supposed to go into the joint.

Re: CPP power steering conversion questions

Thanks for the responses so far guys, I'm still trying to figure this out. Rocknrod has a link which shows the part which attaches the double d shaft to the steering column. I already have that part done. What I can't figure out is the other end of the double d shaft.

I don't know how to post pictures here but the other end of the double d shaft slip fits into a tube which attaches to the rag joint. They call that the intermediate shaft. The double d shaft part that attaches to the steering column is a borgeson universal which locks on with set screws. The other end of the double d shaft slips inside the intermediate shaft. There is no other retention there. It looks like it is designed that way to "collapse" or slide the double d shaft further into the intermediate shaft to let the whole steering column shove forward in a crash.

I'm sure there is some guideline as to how far the double d shaft is supposed to slide into the intermediate shaft to be safely connected, yet allow for forward movement in a crash situation. I have scoured you tube and Google but haven't found anything. They didn't have computers when I went to school so I'm not the most technologically savvy guy out there.

Re: CPP power steering conversion questions

Ok, here is a photo of what I am working with. The silver part on the right attaches to the steering column. The black rag joint on the left attaches to the steering box. If you look in the middle you will see where the black tube with the rubber over accepts the solid silver covered double d shaft. The double d shaft is a cut to fit piece that slides into the rubber cover and into the black tube.

Just how far it is supposed to slide into the tube, and still allow for motion in a crash is what I am trying to find out. I don't know how short to cut the silver double d shaft without knowing this.

Re: CPP power steering conversion questions

I would say the DD shaft should be about half way into the length of the tube. The black part.

Re: CPP power steering conversion questions

Thanks Captain, the official word from CPP today was about half way or far enough in to no longer have any lateral movement.
