When I put the wheel back on, the drum's center section is thicker than stock and the wheel does not fit exactly like it did with the original. the entire thread of each lug nut is not engaged with the studs as it was with the original. Is this the wrong drum or is this not something I need to worry about? Brake works perfectly and well over half the threads are engaged. [Reply]   [No Email]

At first glance they look thicker, not realizing the original one were steel, I thought it was decent product, and for the most part for what you pay for they are. I did however really put them to the test, got stuck at the edge of an old field and marsh, one side lower than the other, but not dug in up to the axle or anything. I believe during the process of getting out, I had a bunch of short 2" diameter alder cut nearby, lined the hole and it got the tractor out, was going to rain heavily, not a good place to leave it so I really used those brakes hard, and I think under what I would call light abuse, one drum cracked in half. That was an extreme situation, cant really think of a time I ever used my brakes like that doing regular work, steel is better, my originals are in good shape but on the shelf.   [Reply]  [No Email]

It came from Turkey and was in excellent condition; it was even painted. I couldn't tell if steel or cast iron. Was the same thickness as the old one where the bolt holes are. Seems all those tractors of that size used pretty much the same shoes and drums. Actually I put a set of shoes for the 100 series tractors on my '65 3000 under this new drum. I didn't know old Ford drums were steel till I read it on here. Sure made a difference knowing that when it came time for me to pull it. Mark   [Reply]  [No Email]

I've seen this setup using an automated mig, and i've seen it done by hand with stick. long thankless process that makes buying a good used steel drum a nice prospect.. :)   [Reply]  [No Email]

The aftermarket brake drums are cast iron, thicker and prone to cracking. I suggest that you find a good used OEM brake drum. Dean   [Reply]  [No Email]

If I could have old drum cleaned up on lathe would it possibly work ok? Old shoes were completely shot, no lining left. Was it the condition of the shoes or drum that was mostly responsible for lack of braking on that side? Left side was like new, right was worn out.   [Reply]  [No Email]

Good, used OEM drums are readily available and modestly priced. From the available information, I would recommend replacing your worn drum with a good used OEM drum. Dean   [Reply]  [No Email]
