will a 40mm bearing exrtactor work for removing a 42 mm bearing?
depends which puller you have, got a link?
Removing it will ruin it, so make sure you have new ones ready. Put the axle in the freezer, then when it’s cold, press the new warm bearings on with a pipe that can only touch the inner race. A cold axle is a little smaller then a warm one.
yep agreed, that one will do either size.
