Borgeson steering shaft installation

[BABIS]

Hello guys,

for those who have installed the borgeson splined steering shaft, do you have filed a flat section over the splines (where the locking screws will go) as stated by borgeson instructions?

I just hit the spot with a drill to give it a little counter sink.

You really should have a flat machined into the shaft so when you tighten that set screw you don't mess up the splines. It won't matter until you have to take it apart. Then you will have a hard time trying to slide the parts apart. In fact, you should also have a hole drilled into the shaft so that the set screw can actually go into the other shaft for a more secure lock. That way even if the set screw should loosen, it is still inside the shaft, holding things together. The put a second set screw int the hole above the first one to lock it into place. You really do not want the steering to ever come apart while you are driving. If you don't trust set screws (and you shouldn't in this application) you could just drill a hole right through and use a bolt and nut.

I did the same as Bitsyncmaster.

Do you have the splined shaft or the DD shaft?

I have the DD shaft.

[Drive Stainless]

I have splined.

I have splined.

Thanks, have you installed the joints mirror phased or with some degree of offset?

Mirror phased.

I'm not sure what you mean by mirror phased, but in general, universal joints should always be installed 90° apart. Unlike constant velocity joints, universal joints do not translate rotational motion at a constant velocity when the joint is at an angle. The greater the angle on the joint, the more the output shaft will speed up and slow down as the input shaft is rotated at a constant speed. This effect is greatly reduced by having 2 universal joints that are offset 90°, and completely eliminated if both joints are operating at the same angle (shaft angle).

If you do not put them 90° however, the effect can be even worse (meaning the rotation of your wheel will be inconsistent with the amount your tires turn, sometimes too much, sometimes too little).

This this 90° offset of universal joints is the inspiration between the double cardan CV joint.

Call Borgeson and let them know. :)

With the DD shaft, I'm unable to phase them in any way other than "mirrored."

Anybody else with a DD shaft report otherwise?

Not sure what you mean. Let them know what? That their diagram is correct? That diagram shows the two joints 90 degrees offset as they're supposed to be. Look at the joints as a whole, the one on the right is rotated 90 degrees from the one on the left.

EDIT: I suppose since the inner halves of the joints are in the same orientation, the term 'Mirrored Phase' does make sense.

About to go do mine. I have the borg steering shaft which I got by buying from Toby at Delorean parts NW. Do I have this guy put together correctly when it calls for it to be "Mirrored"? Looks like it, but i will be taking it apart and fitting it according to tobys procedure.

Forgot to include when I am done I am going to take her for a drive and see how vibration is. After I am going to serious zip tye some door gasket material I have lying around thats about the same size and used as a gasket on air and water tight doors onboard us navy ships. I want to see if i notice a difference in vibration and could be a budget vibration dampener, but i doubt ill keep it on permanently as I dont want to mask any steering problems if I have any in the future.

Looks correct to me. I have the vibration reducing joint and it was a big difference to me.
