TSO Tip
When rebuilding a CR125 crank, always double-check that your crank web alignment is spot-on after pressing. Take your time dialing in the side clearance on the big-end thrust washers to ensure proper oil film thickness, and always install a fresh set of main bearings and seals while you're in the cases to protect your new rotating assembly.
