Alignment of Engine
The chocks may compress 0.001 times the chock height when
the holding down bolts are tightened.
 per 10 mm of chock height align the engine 0.01 mm higher
...but maximum 0.05 mm
 Align close to the top of the allowed coupling tolerance
 Obtain satisfactory alignment and crankshaft deflections
 Check deflections after the job is finished when
temperatures have returned to ambient
