656 wheel/rim/clamp problem (pics)

I had a flat...because a wheel clamp rubbed a hole through the bump in the wheel that is supposed to stop the fore/aft slippage! My fault, I had noticed some shine on the wheel previously. Tires are 13.6x38.

After the tire was off I was able to determine I had play both side to side AND front to back between the clamps and the wheel. All bolts/nuts bottomed out; no room to tighten any of them further.

The"code" stamped on the wheel is [color=blue:47a2c3abf4]W2b 1238[/color:47a2c3abf4] (with a date code of 12/59?) Too early for a 656 unless IH just had warehouses full of this stuff? The wheel part # in the book looks like it s/b 392 415 R1. (The part # on the Rim is 363014 R5 F1.)

I removed quite an assortment of wheel clamps (only one of which looked like it might have had the proper spacing to secure the wheel from slipping front to back. When in Wisconsin last year I picked up a wheel clamp because I knew I was missing one (never put it on). The clamp I got there (part #380870R1) supposedly was off of a 656. That clamp is the one at the right in both of the pictures.

The book says:
381 728 R1 Clamp, Rear Wheel Rim Adjustable -12-
381 726 R1 Clamp, Rear Wheel Rim Fixed -4-

Does that mean I s/b using 6 adjustable clamps per wheel and 2 fixed clamps per wheel? (Is the clamp at the far left an example of an adjustable clamp because it has up/down play in the bolt hole?)

I'm going to flip the wheel around to run in the opposite direction and therefore use the unmolested wheel bumps with the new clamps and keep my spacing the same. Should I go with new IH clamps (if available) or is this a very unusual situation and the ones I'd get from a salvage yard would probably work great? The one from Wisconsin didn't seem to have any wear but that is my only experience.

(Also, what are the nuts with the hoops on the end for. I don't like them; hard to remove.) The other wheel/rim have the same mongrel setup so I can't reference it as an example. As always, thanks for your help.

I always run 'em with four each of the fixed and adjustable clamps alternating between the two.

The loops are to mount a set of clamp-on duals.

Little hard to follow, but if you have a 363014 R5 wheel on tractor, not counting the clamp in far right of picture the next 2 go at the rim stop location and ones like the next 5 on rest of wheel, not sure what last clamp is.

The far left one and the far right one are fixed clamps. Two per rim spaced 90 degrees apart on the rim driving lugs.

TX656: If the tractor was run any length of time with one clamp missing, the rim will be out of shape, and that alone would make it difficult to keep the wheel tight. Even though not all those clamps are 656 specific, if they are not excessively worn or cracked they should tighten and keep the wheel tight. A loose wheel is what caused your wear. You do have to have the proper clamps at the rim bumps.

TX656: What I should have said, is your wheel should tighten with the mix of clamps in the photo as long as you have the right clamps at the hold bump. The clamps must be in good condition, no wear or cracks.

You said 13.6 tires, could be your rim is not right for those hold clamps the others mentioned.

My 656 came from the factory with 14" or 15" wide rims and roughly that same mix of clamps.
