Yes,
. you need a sleeve/spacer to fit on the spindle that goes inbetween the bearings
. a hammer
. a bit of wood
.basically beat one of the bearing cups into the bottom bracket.
.slide the spindle with said spacer/sleeve on(cut to right size) negative space between cups
.beat the other bearing cup into position with spindle and sleeve insitu.
.add any washers to pack the spindle out allowing the crank arms to turn freely without hitting the chainstays.
.put arms and chainwheels on
.tighten up spindle bolts and pinch bolts
.jobs a good un.
ride and enjoy,
