CLEANING/INSPECTION - CONTINUED
Due to excessive weight, assistance will be needed to prevent personal injury when
lifting heavy parts.
Inspection of cylinder block must be performed on a flat surface to prevent distortion. Do
not leave on engine repair stand (page 2-11).
Decision to salvage or discard cylinder block due to crack size or location will be left up
to the repair facility.

If pits and scratches are more than
0.003 inch (0.08 mm) deep in the
area 1/18 to 3/32 inch (1.59 to 2.38
