Critical Inspection
National believes that the inspection phase is most critical in ensuring a quality rebuild. All machine components are inspected against the original print to verify form, fit, and function. National has invested in specialized inspection equipment.
Each drive train component undergoes:
-
A die-penetrant test for cracks
-
A multi-wave ultrasonic inspection to identify cracks or flaws
-
A hardness test to verify correct metallurgy/heat treat
Inspections results are documented and available for customer review.
