Usage:
NOTE: Put a layer of 5P960 Grease or graphite grease on lobes of camshaft when installing.
(1) Width of groove in camshaft for thrust washer (new) ... .190 ± .002 in.(4.83 ± 0.05 mm)
Thickness of thrust washer (new) ... .183 ± .001 in.(4.65 ± 0.03 mm)
End play of the camshaft (new) ... .007 ± .003 in.(0.18 ± 0.08 mm)
Maximum permissible end play (worn) ... .025 in.(0.64 mm)
(2) Diameter of camshaft bearing surface (journal) (new) ... 2.3110 ± .0005 in.(58.699 ± 0.013 mm)
(3) Bore in bearing for camshaft (new) ... 2.3150 ± .0024 in.(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)
(5) Height of camshaft lobes.
To find lobe lift, use the following procedure:
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).
