Usage:
(2) Tight fit between the gear and camshaft ... .0025 to .0055 in.(0.064 to 0.140 mm)
(3) Diameter of the surfaces (journals) for the camshaft bearings. (new) ... 2.7500 ± .0005 in.(69.850 ± 0.013 mm)
Bore in front and rear bearings for the camshaft (new) ... 2.7547 ± .0019 in.(69.969 ±0.048 mm)
Bore in three inner bearings for the camshaft (new) ... 2.7552 ± .0024 in.(69.982 ±0.061 mm)
(4) Thickness of thrust plate used with:
6N6201 Camshaft Group ... .361 ± .002 in.(9.17 ± 0.05 mm)
4N963 Camshaft Group ... .183 ± .001 in.(4.65 ± 0.03 mm)
End play of the camshaft ... .004 to .010 in. (0.10 to 0.25 mm)
(5) Height of camshaft lobes.
To find lobe height, use the following procedure:
A. Measure camshaft lobe height (5).
B. Measure base circle (7).
C. Subtract base circle (STEP B) from lobe height (STEP A). The difference is actual lobe lift.
D. Specified camshaft lobe lift (6) is:
a. Exhaust lobe ... .3458 in.(8.783 mm)
b. Intake lobe ... .3189 in. (8.100 mm)
Maximum permissible difference between actual lobe lift (STEP C) and specified lobe lift (STEP D) is .005 in. (0.13 mm).
