Rollamatic hubs - which hubs are correct??

[mjb8279]

I purchased a rollamatic front with the intention of replacing the square wide front axle on a tractor that I own. I planned to swap the hubs from the square wide axle to the rollamatic since the rollamatic front did not come with hubs. However, the hubs from the square axle did not fit the rollmatic front. How do you tell which hubs will fit a rollamatic front?

The free parts manuals from jdparts.com should show all the info you need.

As a rule, the regular front hubs have very little sticking out past the wheel mounting surface. The cap will almost be touching the wheel. A ROM hub will have much more sticking out as the wheel mounting surface is nearly centered on the hub itself. The conventional hub has a greater offset. Hope this helps. Mike
