I have a couple of questions about these cranks .
The crank on the right came out of a series 1 Li150 of unknown age .It had a bronze small end bush.
The other crank on the left I have no idea of its age although it is obviously a narrow taper crank it has a different taper to the series 1 crank.
Can anyone tell me which series the left crank is ? if you look carefully you can see it has 2x additional oilway holes in the small end to lubricate a needle bearing type small end.
Could it be an SX150 crank ?

Final question.
Both cranks have identical measurements in all respects except The big end width. The series 1 crank has a 14mm big end width and has 0 .011" (.279mm) lateral movement on the journal wheras the other crank has a 13mm width bigend and has a huge 0.075" (1.84mm) of float on the journal.
Are these within tolerance ?
