(58.801 ± 0.061 mm) Clearance  between  bearing  and  bearing  surface (journal)  (new) .002 to .006 in. (0.05 to 0.15 mm) Maximum permissible clearance between bearing and bearing surface  (journal)  (worn) .008 in. (0.20 mm) NOTE:  Make  reference  lo  CYLINDER  BLOCK  for  installation  dimen- sions. (5)  Height  of  camshaft  lobes To find lobs lift, use the procedure that follows: A. Measure camshaft lobe height (5). B. Measure base circle (6). C.  Subtract  base  circle  (STEP  B)  from  lobe  height  (STEP  A).  The difference is actual lobe lift (4). D. Specified camshaft lobe lift (4) is 3300 in. (8.382 mm) Maximum permissible difference between actual lobe lift (STEP C) and specified lobe lift (STEP D) is .010 in. (0.25 mm) (1) (2) (3) (4) Bore in bearing for shaft (new) .7263 ± .0005 in.
