Default Re: Adjustable Drag Link

This thread describes 2 designs for an adjustable drag link
(a) 18" tie rod stock (solid 11/16") with 2 tie rod ends
(b) Original drag link cut in half with 5/8" threaded adjusting sleeve in the middle.

With design (a) the springs on both ends are inboard of the balls. When the drag link is pushed forward by the pitman arm, the pressure between the balls is spring against spring. When the drag link is pulled back, the pressure is solid end cup against solid end cup. Design (b) maintains Fords original where there is aways one spring inboard and one spring outboard no matter if the drag link is pushed forward or pulled back by the pitman arm.

With a spare drag link or a couple of tie rod ends, the time and cost for making either is about the same and pretty small.

Any thoughts on (a) vs. (b) ?

If you have the two tooth steering box this will move the sector off center while driving straight ahead. You will now have play in the steering wheel.

Actually, an adjustable drag link is used to remove the play. Assuming the box is set up and adjusted correctly (no slop/no bind at dead center), a slight difference in the radius of a shortened pitman may result in the wheels not pointing straight ahead when the sector is centered on the worm. Adjusting the length of the drag link (it doesn't take much) will get the wheels lined up with the box and give you equal steering wheel left/right turns stop to stop.

Somewhere it was posted that the tie rod ends version can interfere with the steering arms, etc. Cutting and threading with rt. and left hand dies a used drag link and adding the center clamp may be better. The shortened pitman arm will not allow the steering gear and steering wheel to be at the center point for removing freeplay with wheels straight ahead as posted by others.

His wares are listed on eBay under the name "dav4564d". However, he doesn't have anything listed presently. As noted above he hasn't been on this site for a while, due being kicked off for who knows what reason.

I have one of his adjustable drag links, just waiting to install it when I get a round tuit.

OK, since I couldn't find an adjustable drag link to buy I measured my drag link at .629". So I ordered a 5/8"-18 left hand die nut (already had a right hand die). and a 5/8" adjusting sleeve. Was thinking about cutting out 1" or 1 1/2" and threading both ends. Anyone done this? Is this about right?

That is exactly what did a number of years ago. I seem to recall I removed 2" out of the middle but I'm not sure. Use the length of the sleeve as a guide for the length of the rod and how much thread. With the steering box set up correctly, the drag length adjustment needed should be very small and I wanted to leave as much of the rod as possible.

Sleeve is a MOOG #ES2032S

Have done the one using a Moog adjustable sleeve using the dies as posted on an old extra drag link. Cut enough threads but don't cut out too much of the drag to get the most support from the sleeve. Then fine tune trim the removed drag section as needed.

I bought one off Machine Girl a few years ago when I was unable to get full lock on both sides after fitting a shortened pitman arm. It worked a treat and was an excellent product.
