Crankshaft identity
Numbers are cast or stamped on cranks
Crankshafts are well into their fatigue life and do crack and fail causing much damage
We recommend Minisplus crack test your crank before your rebuild your engine
Approx cost of cracktesting is $48.00 incl gst
We certainly believe wedging improves "life" of crankshafts
