Usage:
(1) Maximum permissible temperature of the gear for installation on the camshaft (do not use a torch) ... 315°C (600°F)
(2) Tight fit between the gear and camshaft ... 0.037 to 0.123 mm (.0015 to .0048 in)
(3) Diameter of the surfaces (journals) for the camshaft bearings (new) ... 69.850 ± 0.013 mm (2.7500 ± .0005 in)
Bore in front bearing for the camshaft (after assembly) ... 69.969 ± 0.048 mm (2.7547 ± .0019 in)
Bore in the other six bearings for the camshaft (after assembly) ... 69.982 ± 0.061 mm (2.7552 ± .0024 in)
(4) Thickness of thrust plate (new) ... 4.65 ± 0.03 mm (.183 ± .001 in)
End play of the camshaft ... 0.10 to 0.26 mm (.004 to .010 in)
(5) Height of camshaft lobes.
To find lobe height, use the procedure that follows:
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 (6).
D. Specified camshaft lobe lift (6) is:
a. Exhaust lobe ... 10.210 mm (.4020 in)
b. Intake lobe ... 10.212 mm (.4021 in)
Minimum permissible difference between actual lobe lift (STEP C) and specified lobe lift (STEP D) is 0.13 mm (.005 in)
