Sidecar wheel nut (cT only)

The Ural cT uses a special nut designed to bear directly onto the outboard wheel bearing's inner race. (Honestly this should be good for any 1WD sidecar wheel that uses ball bearings rather than the old tapered bearings.)

If you've inferred that one should not install a washer between this nut and the wheel, you are correct. Chad knows. But in Chad's defense, the first year of cT (2015) did not get this special nut. But... it should have. It changed in 2016.

(But you do put a washer between the sidecar wheel hub and the swingarm. In other words, install the flat washer onto the axle, then slide the wheel on, then install this nut. (And then a cotter pin to prevent the nut from vibrating off. Aaaand then the black plastic cap.)
