Comment: Answer to question #5 is incorrect. It states that bearings matched to the crankshaft should be oversized. This is incorrect. The bearings needed are undersized due to the inside diameter. The bearings now form a smaller diameter which makes them undersized. The bearing manufactures will identify this on the back of the bearing with a mark like this - 0.010us. The correct answer should be A
