I have what appears to be a firm and intact upper 2nd roller on my
M600 (it's the other one that's turning to goo)
I measured the roller to be:
O.D. (rubber) 26.6mm (~1.048")
hub O.D. (metal) ~13.9mm (~0.55")
I.D. (metal) ~6.4mm (fits 1/4 D-shaft)
width ~9.5 (0.375 - seems to be 3/8")
...in case it's possible to find a standard roller. The shaft
diameter and roller width are certainly common Imperial values.
