Into the NSR motor now, and all three main crank bearings have play, the 2 end ones not so much but the middle one about double what the end ones have. And the big end bearings on the con rods seem to have a bit.
Just wondering how much play is bad for a bearing and how to properly test them for play, pure radial movement of the races or axial or twisting or what.
Any info much appreciated.
