The surface accuracy after grinding should meet the standard value requirements.

Note: The thickness difference between the two front and rear Mitsubishi R16 diesel engine thrust plates does not exceed 0.25 mm.

5.7 Measure the runout of crankshaft of Mitsubishi R16 diesel engine

The front and rear journal seats of the Mitsubishi R16 diesel engine crankshaft were seated on a V-shaped iron block, and the runout of the central journal was measured. Refer to the standard value, and use the grinding method to correct the smaller runout. Larger runout is corrected with a pressure gauge. Replace the new Mitsubishi R16 diesel engine crankshaft when the limit is exceeded. When using abrasives or presses, perform magnetic inspections on all parts to confirm that there are no harmful cracks or damage.
