benny81 Posted August 19, 2011 Share Posted August 19, 2011 Hello, Does anyone know the size of the bearing on the top of the pinion gear on Shimano's Sienna 2500FB and/or Alivio 2500FA please? I am also thinking of replacing the main gear bushes with bearings, as they are a bit sloppy, though it is not practical at the manufacturer's RRP, any tips as to supply/size would be well appreciated. Thanks. Link to comment Share on other sites More sharing options...

slinkymalinky Posted March 3, 2012 Share Posted March 3, 2012 G'day Benny, Get yourself a set of digital calipers. I got a set from an auto shop for about $20. I use them all the time to measure bearings and drag washers... then you can order whatever bearings you need, whenever you need them.
