I have a 68 1-ton "crummy", it's a old forrest service crew turck and I would like to put on a set of wheels froma 99 ford duely. The center hubs on the old spilt wheels are smaller than the newer wheels. Do any of you know where I can get, or if anyone makes a centering ring to center the wheels on the hubs? I know that the hubs on the newer trucks center the wheels and the older trucks it's the lug nuts.
Bertha66, i'm running 79 1 ton wheels, 6 3/4" front and 9 3/4" single rear on a 68 3/4 ton truck. On the rears the wheel center clears the hub by 1/16" all around. The load is on the studs and nuts. Carl.....o&o>..........
I have the 99 wheels on the 68, lug pattern is same, but the lug hole are not taippered to center the wheels on the studs. The local wheel shop is the ones who said that they, 99 wheels center to the hub.
Bertha66 is right. The newer Superduty trucks have wheels that center on the hub. I know at least the 8 lug wheels do. Very little slop on the lug holes and wheel studs. The lug nuts "clamp" down onto the wheel. I wonder if the older wheels will fit on the Superduty.
I know the old Fords are 8x6.5" bolt pattern and the new one have a metric bolt pattern (8x170mm, I believe). They may be close, but they are not the same. Did you have a hard time getting them on the lugs?
As for the centering, you think you could find a sleeve to tighten things up, but it might have to be custom made.
What's the gap between the rim bore and hub? What about machining a ring and Tig welding the ring in on the back side in short stitch without filler rod. Done right you won't burn the paint. Carl....o&o>......
The gap is about 3/16"' will have to pull the wheels and put a caliper on it to check. I was told yesterday that some late 80's f-350's had a adaptor plate from the factory that will fix this problem, will need to call local wrecking yard to see.
