Usage:
(1) Diameter of bearing surface (journal) of the camshaft ... 2.6195 ± .0005 in.(66.535 ± 0.013 mm)
(2) Get temperature of the gear to a maximum of 750°F (398°C) before installation on the camshaft.
Diameter of shaft for gear ... 2.6833 ± .0005 in.(68.156 ± 0.013 mm)
Bore in gear ... 2.6795 ± .0003 in.(68.059 ± 0.008 mm)
(3) Torque for nuts ... 75 ± 10 lb. ft.(100 ± 14 N·m)
(4) Diameter of seat for gear ... 4.748 ± .001 in.(120.60 ± 0.03 mm)
Bore in gear ... 4.750 to 4.751 in.(120.65 to 120.68 mm)
(5) End play for the camshaft ... .010 to .020 in.(0.25 to 0.51 mm)
Maximum permissible end play for the camshaft ... .035 in.(0.89 mm)
(6) Bore in bearings for camshaft ... 2.6235 ± .0015 in.(66.637 ± 0.038 mm)
(7) Bore in housing for bearings ... 2.874 to 2.875 in.(73.00 to 73.03 mm)
(8) Distance from bearing to face of housing ... .03 in.(0.8 mm)
(9) Distance from end of dowel to face of housing ... .19 in.(4.8 mm)
(10) Height of camshaft lobes.
To find lobe lift, use the following procedure:
A. Measure camshaft lobe height (11).
B. Measure base circle (12).
C. Subtract base circle (STEP B) from lobe height (STEP A). The difference is actual lobe lift (10).
D. Specified camshaft lobe lift (10) is ... .4030 in.(10.236 mm)
Maximum permissible difference between actual lobe lift (STEP C) and specified lobe lift (STEP D) is .010 in. (0.25 mm).
