  1. Check camshaft lobes and journals for wear or damage. Measure height of lobes with a micrometer. Replace camshaft if measurement is less than 1.432" (36.37 mm).
  2. Measure camshaft journals. Replace camshaft if journal diameter is less than 1.331" (33.83 mm) or if difference between largest and smallest journal (taper) is more than .002" (.05 mm).
  3. Place camshaft on "V" blocks and check runout at center journal. Replace camshaft if runout exceeds .004" (0.1 mm). A slight amount of runout can be corrected with a press. DO NOT  apply heat.
