More Pie Weight Comparison

The white set (actually Ford light gray, but for the sake of simplicity)
is what I believe are commonly referred to as the heavy AG set.
Each pie segment weighs 42 lbs. Measurements in the pictures.

The other set is what I believe are commonly called the heavy
"industrial" style. Each segment weighs 38 lbs, so not the light set.
Measurements also in the pictures. The rusty set is one inch shorter
from the outside edge to the mounting hole, making the outside
diameter when assembled about 24 inches. The white set being
an inch longer measures 26 inches across when assembled.

I think the rusty set would work with PA rims. The white ones
would fit but not allow adjustment of the PA rims. Neither set
would work on a 24 inch rim unless the rims were adjusted all
the way in and the weights were allowed to sit outside the rim.
Sound right?
The rusty ones will be on their way to the sandblaster soon.

Royse, I think I have a set of the industrial 24 inch weights on my power adjust rims. I dont think I could adjust the width, but they do fit oriented as shown.

Those look similar to my "rusty" set michford.
I think if you pulled a weight to get at each of the clamps, you
could adjust the wheels. My "white" weights wouldn't allow the
rails to pass to adjust them even if you got the clamps off.
At least, that's my thinking. Others will correct me if not.
 
All weights would have to come off to adjust as each weight segment has a notch at the back and the notch is what allows the segment to fit over the clamp bolt.
 
I think I understand what you're saying.
Those bolts don't just come out either.
If you did pop them out and replace them with carriage bolts,
which I've had to do, they would clear with the bolts removed,
but then you'd have to deal with holding the carriage bolts in
while putting the clamps back on.
 
First off let me say I have never tried to spin the PA's out or in with the weights on. Once the weights go on they ain't gettin moved. I would think you
would have to take several weights off to access the clamps cause once you pop them I don't know if there's enough thread on the back side of the
carriage bolt to hang them loose and what would you do with your stop clamp. The pies would have to come out to access that so you could move your stop
clamp to another rail. Even with the light duty pies I don't think there's enough room as shown on my 640. Rust and CalC have taken there toll on most of
my Pa rims and I have fought with bowed rails for years just to get them in the right spot. I do have one set that work in and out like they were suppose.
That set will probably go on a tractor and used at a show for demonstration of it's use

Here's some info on wheel weights taken directly from the 600/800 Operator's Manual. Also, there was a special set of wheel weights made specifically for the Dearborn 19-35 Road Maintainer.

Early Ford PA rims can be adjusted with compatible pie weights installed by removing only 4 weights if the mounting disc is properly indexed.

Simply pop the clamp bolts out with a punch for clearance and adjust in quarter turn increments. Once adjusted, simply pop the clamp bolts back in. The OEM bolts are a semi-interference fit and will stay in place if not badly worn or badly corrosion damaged.

You will need to adjust in quarter turn increments, which is more than sufficient resolution for any task.

I never use tractor power to adjust PA rims. Rather I jack up the tractor and adjust manually. I count turns when adjusting.

If you desire to use the spacer clamp for power adjustment (who does?), you will need to use it on the inside or you may need to remove more weights.

Must be my lucky day. I managed to get the old weights off and
the newly sandblasted and painted weights on without chipping
or scratching the paint and without smashing a finger! :)
I like the profile being closer in than the other set was.

The centers are different between the two sets also. Not only the
thickness and weight, but the rusty ones are 1/4 wider in diameter
and the extender holes are flat, where the white set extender
holes are counter sunk.

Both the Elenco and Sherman Napco conversions were available for the 4 speed trans and 5 speed trans. There is a specific coupler used for each converion kit depending on the transmission.
 
I agree with Dean about the white disc probably used with light duty set. Ford use different foundries for there weights so the disc and weights could be
different. You will find this more when you start piecing sets together. In the weights I have had over the years I have seen 5 different styles of
mounting plates. They even made a 4 hole instead of 8 hole disc for the light duty weights. Also if you measure the thickness on the plate where the pie
mounts and the gap in the pie where it mounts there could also be a difference. I noticed this more between the Industrial and Ag models. Difference is
slight so mounting may not be affected. As I said more noticeable when piecing them together.
 
The Elenco was available with the SOS, but I have not seen anything about the Sherman Napco being available on an SOS. The Sherman Napco parts manual lists a drive sprocket for the 4 speed and a drive sprocket for the 5 speed, but does not list one for the SOS.
 
I once had a 4 hole pair of discs but sold them with a light set several years ago.
