The right side bearing on the csr has to be installed first, then install the flanged collar/spacer thru the left/speedo side, then the left side bearing. On the csr that collar can only be installed thru the left side, so on your bike test fit the collar to verify which bearing should be done first. To deter corrosion I applied a thin coat of marine bearing grease to the axle & collar.
I think when the axle nut is tightened, the collar contacts the inner races.
To install the bearings apply a light coating of wheel bearing grease to the outer races & wheel so that they can be driven easier. I use a bona fide bearing driver. some guys improvise, instead of buying the tool.
well what's weird is if I get both bearings in, that collar will be touching the inner races of both bearings causing them to no want to spin.
