Had what could be the same issue with mine - If you buy bearings from any Duc dealer now for your 851 or T8, either front or rear, there should also be a spacer which is placed into each side of the wheel before the bearing is pushed home. This as the bearings are now thinner.
The dealer up here didn't order up the spacer kits, which are just zinc plated steel rings, when I installed the 1st bearing I noted it was 3-4mm sub flush and would have caused the wheel to lock if I'd installed the other bearing and re-fitted the wheel. Dealer got me the spacer rings and a new bearing and the thing was right as rain.
If you can get hold of the old bearings get yourself down to the local bearing traders and they'll sort you out with the correct width bearing and it'll be a damned site cheaper than the Duc option.
