The 2 7/8" axle was used clear back to the model 50 through the 520 and 530. I believe some early 4030's also used this size axle. It may be possible to use the axle wedges from any of the older tractors in the hubs you may have. The taper angle of these hubs was changed at some point so compare the hub casting number with a wheel casting number, such as the common F1500R. Many of those wedges will work in the earlier dual hubs. The later hubs that may have the different taper angle would require a later (and harder to find) wheel wedge. It can be done and has been but you need to be a good student of the parts books. Mike [Reply]  [No Email]

They are the same. Yes, they are 2 7/8" axles. You might get about 8" of axle at the most if the wheels are rolled way in. A little more if you removed the push bolts. I suppose the whole effort would be easier with tires narrower than 15.5. I was thinking the same thing, but ended up with wide spaced clamp on duals, spaced for 30" rows. [Reply]  [No Email]
