(12) Height of camshaft lobes. Typical example exhaust, intake, and injector lobes.To find lobe height, use the procedure that follows: a. Measure camshaft lobe height (12).b. Measure base circle (13).Exhaust ... 55.0 0.4 mm (2.17 .02 in)Intake ... 51.0 0.4 mm (2.01 .02 in)c. Subtract base circle (step b) from lobe height (step a). The difference is actual lobe lift (11).d. Specified camshaft lobe lift is:Exhaust lobe ... 9.550 mm (.3760 in)Intake lobe ... 11.371 mm (.4480 in)Injector lobe ... 11.205 mm (.4410 in)Minimum permissible difference between actual lobe lift (STEP C) and specified lobe lift (STEP D) is ... 0.13 mm (.005 in)
