Farmall 50A, 60A, 70A Wheel Spacers

[klancf51]

I need to add wheel space for a Farmall 70A with 4WD. Case IH doesn't carry wheel spacers for these Farmall A utility tractors, so I will have to have them made, and accurate wheel dimensions are required. I measured the rear wheel pattern for the 14.9-28 R1 wheel plate: 8x203.2 mm bolt circle with 152 mm wheel center bore, M16x1.5 threaded studs. The fasteners are M16x1.5 flange wheel nuts. As it turns out, this ag wheel pattern (8x8" bolt circle, 6" bore) is not uncommon, so I am confident in the rear wheel dimensions.

The front wheel pattern is a bit more difficult because of the hub for the MFD. The fasteners are six M16x1.5x35 mm hex cap screws, Gr 8.8, full thread, Zinc Chromate finish; requiring flat washers (16.4mm ID x 28 mm OD x 3 mm Thickness, Gr 8.8, Zinc Chromate finish). That's about all I am certain of. Does anyone know, for certain, the front wheel pattern for the Farmall 50A, 60A, 70A models with the MFD front axle (9.5-24 R1 tire)? Or otherwise, front wheel spacer dimensions?

Thanks!

Good luck on finding ANY wheel spacers anywhere. Most places are on back order for 18 to 24 months.

Most of the spacers are made from 6061-T6 aluminum; durable, holds up well and resists corrosion.
