The yoke's hinge point on the mounting bracket should be 18" from the center of the ball socket according to the installation directions.

And then, generally, there should 5 links from the hangar bracket to the hook. That can be adjusted by tilting the ball.

I suspect you know all of this, but thought I'd lay it out anyway. BTW - beautiful workmanship on that kayak!

Jim,

18" is for the round bars. For trunnions, the instructions say 19 3/8"....and that's not enough with the new part numbers, as the OP and I have found out. They need to be about 20"! HOWEVER, I don't think that's why the bolts snapped. The stresses really don't change dependent on cam arm length...only by spring flex and some associated friction. I think the knowledgeable metalurgists above have the right answer. Now I gotta run out and get me some grade 8s. My AS is at the storage lot. Does anybody have the size and pitch we're looking for?

My bolts were put on by a air wrench set very low. Just enough to snug them.

dznf0g,

You're are looking at the new install instructions. It wasn't easy to find the pre-2010 directions, but check them out here on pg2, section 3:

http://www.airforums.com/forums/f464...tml#post980268

As far as snapping bolts are concerned, I'm going to have the brackets welded to the A-Frame.

Also, I know from experience that these bolts loosen and there may have been increased stresses do to this. Once the heads snapped off, one would never know.

That link isn't going anywhere.....but if the old one states 18" and the new one states 19 3/8" both for the trunnion style square bars, that does support a shorter assembly. But as catsandi and I found, that is still not enough.

Wait a minute. I have to rethink all the fiddling I did during my initial setup. I forgot some of it...thank goodness I took some pics so I can retrace my steps.

Initially, I had my yoke bracket set in the same direction as in post #3, with the bolt mount toward the rear of the trailer, mounted with the bolt head center 19 3/4" from ball center. After getting the proper WD setup, by adjusting head tilt and with 5 links under tension, there was not enough adjustment INWARD on the cam to get me to center of spring saddle. I ran out of thread, albeit, barely.

I then swapped sides with the yoke brackets, so that the bolt mount was toward the ball end of the tongue. I can't remember the distance from bolt to center of ball this way, but it extends the cam bar out too far. It's OK, I think but the threaded portion only just completely fills all the nut threads.....nothing sticking out. Operated fine for the 980 miles home.

Now I've got myself really confused on the differences between the new and old part number. It would be really nice to see the components laid out next to one another.

I checked out the bars and there is some chipping on the bars paint so it might have come in contact while I was slow maneuvering the trailer. After u had the new bolts installed I did several laps around the rv center with the mechanic watching and they didn't bind or make contact.

The picture attached is where the second bolt sheared off.

Given my uncertainy of the quality of the material used in the arm and cam assembly, I am giving up on Reese. I talked to the local Reese dealer this morning. They are going to accept my arms and brackets as a warranty return.

I am changing over the the Equalizer system.

Anyone want a Reese head and 1200lb bars cheap?

Not sure you will get any satisfaction from Cequent but here is their phone number. In the past they have replaced quite a few new parts because of poor quality in manufacturing. There parts are now made in Mexico and have ZERO quality control.

At least you can register your thoughts.

Thanks Howie,
I have already called them and registered my feeling on their products.
