X634 R7/M20.10.31. X634 X7010 X5010 BALANCING OF CRANK - 12/8 SCHEME OF BALANCE WEIGHTS. I cannot see any reason why it should not be easy to balance a crankshaft which has been machined all over, when one has added the two central and the two end ba,ance weights which naturally come in right postions and have been made of equal effective balance. Static balance should shew if the four half units at 30° are correct in weight distance from the centre. R.{Sir Henry Royce} | ||
