Crankshaft Sanding and Polishing by Hand DIY You can do this!

Follow me on Instagram @JL335i In this video I go over the steps to bring those crank rod journals back to life with a polished finish perfect for new bearings to ride on. Rod bearings are very very soft so if you have any scuffs on your crank journals it will bite into the bearing causing debris...scoring...and premature bearing failure. #diy #crankshaft #mishimoto #cooledbymishimoto #teammishi #n54 #n54builds #n54addicts #n54single #jb4 #mhd #xhpstage3 #e92 #e92coupe #335i #335icoupe #335ination #bimmerlifetuning #bmw #linelock
