INTRODUCTION
Scope
This appendix lists the repair specifications for the 6V53/6V53T Diesel Engines. Refer to Table 1.
Explanation of Columns for the Repair Specifications List
Column 1 - Point of Measurement - This column lists the area of the engine (e.g., CYLINDER BLOCK), then lists
the specific component (e.g., Main Bearing Bore), and finally describes the critical dimension (e.g., Inside
diameter).
Column 2 - New Minimum - This column lists the minimum acceptable dimension of the new part. All dimensions
are in inches unless stated differently.
Column 3 - New Maximum -This column lists the maximum acceptable dimension of the new part. All dimensions
are in inches unless stated differently.
Column 4 - Wear Limit - This column lists the maximum acceptable deviation for the used part. All dimensions are
in inches unless stated differently. An asterisk (*) in this column indicates the part must keep the same minimum
and maximum limit as the new part.
