A day ago my tower terror clutch bell locked up, So it wouldint start or even move by pushing it. So i tried too take the clutch bell off, And when i finally got it off, The bearing inside there was nothing left, And small balls was siting in there so the bearing mustve shatterd, So right now i have it back togther and just have the outer bearing on, And it drives fine now but would like too get new bearings, And was wondering will these fit it? http://www.amazon.com/HPI-Racing-B02...7591043&sr=8-5

On tower hobbies they said 5x10mm will fit so i looked on amazon because they fast shipping, And found thoes but not sure what the 4mm on the end means?
