pie weights ( new post)

I have a set of heavy 1200# weights fitting 28" wheels. I have a set of heavy 1200# weights fitting (24"wheels) or PARW. I just went out and interchanged one . They fit no problem. 10 1/2" weight mounting bolt diameter. Am wander how a smaller diameter disc will except the pie weights in the center, unless they are different weights

I just measured the odd very thick mounting disc that I have in the miscellaneous pile. It measures 18" OD, the same as all of the 28" mounting discs that I have.

This odd disc came with a few odd weights that I picked up at a scrapper a few years ago and I have never used it. I assumed that it was for 24" rims but am not certain. It is certainly considerably heavier than the commonly seen mounting disc for "heavy" sets.

Therefore, I have no smaller diameter mounting disc for 28" rims, as I thought I did, and either my odd disc is not for 24" rims or 24" rims use the same 18" diameter mounting disc as do 28" rims.

I bought a set of heavy 28" pie weights a few years ago. The plates were mismatched.
One was the standard type like you generally see on all the 28" weight sets. The other one was the extra heavy style like you mention.
The extra heavy plate did not fit up to the wheel properly. The extra cross hatching hit the 28" center and the lug nuts did not screw onto the stud nuts all the way. But they did work and the segments all bolted up fine.
It was when Kenny took his heavy 24" weights off of his 841 with 24" rims that I realized his plates were like my odd/heavy one. The extra cross hatching is curved to fit 24" centers but interferes with 28" centers.
I assumed the extra cross hatching/weight was because the 24" segments hang out so much farther.
I was going to chuck the heavy plate up in the lathe and face about 1/4" off the inside of it so it would fit my 28" center better but then found a pair of correct, 28" plates and sold the other pair.
To reiterate here; the diameter of the plates was the same and both sizes - 24/28" of segments bolted on no problem.
That is my experience. But I like many here know not to use the terms never or always when dealing with these Fords.

Different weights depending on which foundry they were made at. 24" industrial weigh on top right.

It seems like if the center was smaller and the weights were the
same, the sides of the weights would touch and they wouldn't
move in to bolt to the plate. Maybe a combination of both?

How about the outside diameter when they're all mounted.
That would have to change wouldn't it? Anyone have that measurement?
Kirk's photo seems to show a light gray 24" weight being much
further away from that 28 in rim than the others.

Here's some measurements I took of a segment I have here.
These are on an 18 inch plate with a 10 wide bolt pattern.

If there are 12 weights in each set, no matter what kind of set it is, then each pie segment would take up 1/12 of 360 degrees, or 30 degrees each (minus a little for the gap between the pie segments of course). The difference looks to be mostly how "thick" each weight is (how far they stick out from the wheel center) and the profile of the outer rim edge of the pie segment.

I think we're talking about the same thing.
Using rounded numbers here, a 28 inch diameter (I know it would be less to fit inside the rim) would have a circumference of 88 inches.
Divide that by 12 segments and each one would be ~7.3 inches wide at the outside. Excluding the gap of course.

Using a 24 inch diameter, circumference becomes 75.4 inches and 1/12 of that would be 6.3 inches wide. Again excluding gaps.

So it seems if only the plate were smaller diameter and you tried to move the wedges that were 7+ inches in to a smaller plate, they would hit before they moved in that far. No?

If you took that same weight segment and cut an inch off the outside end, it would be shorter in my second picture,
and narrower in my third picture. Sure wish I had them all here to compare.

I'm going to look at those weights tomorrow, even though the measurements match mine.
The outside diameter of mine assembled on a 28 inch rim is 24 inches. Obviously these would not fit inside a 24 inch rim.
If he'll let me attach two segments, I can measure the outside diameter of those too.

So it seems if only the plate were smaller diameter and you tried to move the wedges that were 7+ inches in to a smaller plate, they would hit before they moved in that far. No

I agree with that. Kirk's picture shows a full set of 12 weights on a single wheel and a single mounting plate with two of the weights being different styles from the rest. The only thing is that those two "odd" weights aren't bolted down, and it looks like the 24" industrial weight can't slide down far enough for its hole to line up with the hole in the plate, so I would say that the 24" weights wouldn't work with a 28" plate, but you could probably get a full set of 24" weights with a plate designed for a 24" wheel to bolt up to a 28" wheel.

Center lug nut bolt are the same for 24" or 28" rim so either plate could be mounted.

I took my weight, the rusty one in the picture with me when I went
to look at them. They are the same, although his are in better shape.
18 inch center, 10 inches straight across the weight mounting holes,
24 inches across the entire diameter with weights mounted.
So I believe that makes them the heavy 28 inch weights.
Same as the other two sets I have so I didn't buy them.
Still a good deal. They were missing one extender, otherwise all there.

What do with valve stem if it is on outside?

"What do with valve stem if it is on outside?"

Two of the pie pieces, one for each side, has a notch in it for the valve stem.
