Such misalignment may make it difficult to manu-
ally turne the crankshaft. Verification can be done
by measuring deflection each end of crankshaft.
If deflection is found greater than specified toler-
ance, this indicates worn bearing(s), bent and/or
disaligned crankshaft. Proceed with the disassem-
bly of the engine.

the engine disassembled.
