Oliver 880 Brakes

Last Thursday I replaced the brake discs in the 880 and set them so the pedal stopped in the center of travel. I went to move it Friday to get the lawnmowers out and it would barely move. I backed the adjusters off and tapped on the adjusting bolts to get them free and it was still dragging bad. Today I jacked up one wheel at a time, couldn’t turn the wheels at all. Took the brakes back apart and found that when I loosened the covers I could turn the wheel. I compared the new discs to the old ones and the new ones are thicker than the old ones and won’t fit with the cover on. I ended up putting one old one back in, having one new and one old disc in it and now I have brakes. I checked part numbers and the new ones from A&I are the correct part numbers. I never had this happen before.

Have not worked on 880 brakes, but on a 1750 there are shims to move the cover out till the brakes wear, then can remove shims as needed.
 
Yes, I have shims for the 1850, Agco parts page doesn't show any shims for the 880.
