Reference Answer
(a) Checking of alignment
To check whether the alignment is acceptable, the crankshaft deflection readings are taken.
From that reading, the deflections in the vertical and horizontal planes are obtained by calculation.
The calculated figures are compared with the maximum allowable figures from the maker instruction book.
