Using outside caliper micrometer, measure and note outside diameter of each bearing journal (10).  Measurement must be 2.200-2.201 in.  (5.588-5.591 cm).  If bearing journal diameter is less than 2.199 in.  (5.585 cm), replace camshaft (7). 4. Using inside caliper micrometer, measure and note inside diameter of bearing bore (11). 5. Subtract measurement taken in step 4 from measurement taken in step 3.  Measurement must be 0.004-0.006 in. (0.102-0.152 mm).  If measurement is greater than 0.007 in.  (0.178 mm), replace camshaft (7). 6. Using  outside  caliper  micrometer,  measure  and note   outside   diameter   of   each   camshaft   lobe (12)   at   highest   and   lowest   points.      Subtract lowest measurement from highest measurement to   find   camshaft   lobe   height.      Camshaft   lobe height   must   be   0.266-0.286   in.      (6.756-7.264 mm).  If measurement is not within specification, replace camshaft (7). 5-49
