Camshaft & Rocker Arm Assembly: Inspection

  1. Inspect camshaft lobes, journals and distributor drive gear for wear or damage. Measure height of camshaft lobes. Replace camshaft if measurement is less than 1.432" (36.37 mm).
  2. Measure camshaft journals. If journal diameter is less than 1.331" (33.83 mm) or if difference between largest and smallest journal is more than .002" (.05 mm), replace camshaft.
  3. Place camshaft on "V" blocks and check runout at center journal. If runout exceeds .004" (.10 mm), replace camshaft. A slight amount of runout can be corrected with a press. DO NOT  apply heat.
