Do any of you fellas have a hub off a model A cast wheel? I need a center to center measurement of the 6 bolt pattern. I can't get a really accurate measurement off of mine with them still bolted to the tractor. My uncle is scrapping a 4430 and he said I can have the outside set of tires and wheels for my model A (yay for me because my tires are shot! :lol: ). I'll just have to make a set of adapter plates to make the nine bolt wheels work. Heck, if any of you know what the spacing for a nine bolt wheel is it would save me a 25 mile trip to measure a set of wheels I have at my dads place. :lol:

Thanks guys.

Those are the hubs that I wish I had. :lol: Actually, now that I think of it, if you wouldn't mind, there are a couple more measurements off that hub that would be very helpful.
#1....bolt pattern
#2.....the diameter of the hub plate
#3.....on the other side of the hub, I believe there should be a raised circle that centers the hub in the wheel. The diameter of that would be a big help.

Thanks a bunch!

Try going to http://mcgrewtractorparts.com/ and tell them that you want some model A hubs. They have quite the supply of tractors that they are constantly selling off the individual parts.
I contacted them last week. Very nice people. They had a set for $300 plus shipping but its duck season so all of my spare money is spoken for. :lol: I already have the steel and access to the tools needed to make some adapter plates.

Bolt pattern measurements are 3 1/4 center to center on neighboring holes!



Bolt pattern measurements are 9 3/8 center to center opposite side!



raised circle is 7 3/4!


the other measurement your requesting i'm not entirely what your asking!

My guess he needs the od of the hub. How tall the raised area is. Distance from center for the 6 larger holes. Distance from center for the smaller 9 holes. Overall thickness of the hub (measure through splined area). Thickness of the flange where the 9 holes are. The outside diameter on the other side for the minimum diameter at the smallest of the taper. Then the largest od of the taper.

At least that is what I would need to know if I were to reproduce it in a machine shop.

Thanks 454! That will get me a good start on my project. I think the only other measurement I need off your hub is the diameter of the whole hub plate. By the looks of one of the pictures I'm thinking it will be 10.5 to 11 inches across.

Now all I need is the measurement of the six bolt pattern used on the hubs for cast wheels.

It would make you sick.....the tractor is beautiful. He just repainted it about six years ago and it gets parked in a barn. Here in California they have what is similar to the cash for clunkers, but its for tractors. The state will give him $28,000 twards a new tractor. All of his ground is in almonds now and the 4430 is just to big to work the orchards. He's going to get another one of those new little 100 horse John Deere orchard tractors.
