Oh and if you go with the Dexter # 11 your minimum weight rating is 3800#, not a bad thing with the triple axle setup.

Steve.

I would suggest that you increase the axle rating to 4000 pounds, as that's what they are on later 34's.

The hub face to hub face is 80.75"

You can also now get them with self adjusting electric brakes, or if you wish, you could upgrade to disc brakes.

The basic difference is the cost of the actuator.

OK I have a L S Starrett 12" Vernier Caliper inbound. If I am lucky it will be here Saturday via Priority Mail.

I have a form made out I will publish on my gmail account with a link for all to reference and a blank form others are welcome to use when measuring their units to order axles.

I will measure all four hole locations C-C, I-I and O-O and figure a average.( I already know the hole sizes are different on the first set of holes).

I will also measure all hole sizes so we will have a range of hole sizes known for reference purposes at least for a 76 Sovereign 31'.

The place I am getting mine from will custom drill holes on locations you spec.

You don't need calipers to measure the distance CC on the holes. If the holes are round and the same size, just measure from edge to edge. Measure from the left edge of one hole to the left edge of the other hole for example.

My holes vary in size by like .035" ! ! ! ! if I remember correctly. As well the inside of the holes being stamped are shall we say chamfered. Personally I would prefer a rather precise reading as I have machine operations background and own my own lathe and mill and a caliper to me is the way to go as I know it will give much more precise measurement for the actual hole locations C-C.

Assuming the hole locations are identical on all the 31 Sovereigns then those of us that have them will know what to order for a more precise fit.
My data that I publish will need to be confirmed by several others of course.

I haven't forgotten the measurements. It is just this Gout has got me crippled now but getting better slowly. I cannot wear left shoe at all.

I did get in my Starrett Vernier and though it is old it is as if hardly ever used and checks out good. Soon as I can walk half way I will measure the sets of mounting holes.

This is template I fabricated that aligned the AS frame holes with the axle shaft so I knew exactly where to relieve the mounting plate to install the axle.

You're so close on the dimensions that I don't think it'd make a difference, but the factory specs are 86.43" hub face and 67.125" outside bracket dimension.

Thanks Greg. I got a PM that 2 of my measurements were off, but no indication of which two. It really did scare me because if it's done wrong, it's on me. Well, the Six Robblees Distributor has a 50% restocking fee. Which I think is generous knowing that if it's done wrong, it's pretty much scrap metal.

It's also pretty difficult to make the measurements by yourself with them on the trailer. I would take one off to measure it, but I have to cut one of the bolts to get it off. The spindle arm doesn't move out of the way.

You're right, the Hub face probably won't make a difference, and 1/16th on each side of the mounting plate won't be a deal killer. I'm just surprised that I was off by that much.

I haven't made the order yet, but I will this week. I might do my measurement with a neighbor since the wife is not really excited about being my helper.

Here is what the old (1976)factory 3200 lb axles looked like after having weight off them for three weeks up on jack stands and the new 5200 lb axle just installed.


This is bracket I made. One set of holes locates 8 Lug Hub face and the other a 6 Lug (Airstream) Hub face.


This shows how bracket is attached to hubs to measure the hub face on one side.



And this is the other side. This way you get a dead match for the axle you are removing and you can look at how your wheels locate in the wells and you can change this dimension. On mine the left side mounted closer in than right side so I increased the hub face dimension a tad to center the wheel a little better in the well.

Henschen always said, never increase the rating more than 15 percent, or there abouts.

Your's have increased over 60 percent.

Unless your Airstream is very heavily loaded, which the chassis cannot handle, watch for sheared rivets, and fatigue crack damages, to the shell and chassis.

Those are the warnings issued by Henschen many years ago.

Andy
