matching with the bearing width, and then place it on the journal in the axis direction.
(4) Fit the camshaft cover (See——Removal/Installation of Cylinder Head, Precautions to the
Installation of Camshaft).
Attention: Do not turn the camshaft while measuring the clearance.
(5) Disassemble the camshaft cover (See——Removal/Installation of Cylinder Head,
Precautions to the Disassembly of Camshaft).
(6) Measure the widest point of extruded part of clearance gauge of plastic line by use of the
scale on the clearance gauge of plastic line, resulting therefore in the journal clearance.
Replace the cylinder head and camshaft cover when necessary.
Standard journal clearance: 0.035～0.081mm{0.0014～0.0031in}
5. Fit the camshaft cover (See——Removal/Installation of Cylinder Head, Precautions to the
Disassembly of Camshaft).
6. As shown in the following Fig., fit the dial gauge, push forward/rearward the camshaft from
its back, measure the end gap of camshaft. Replace the cylinder head or camshaft when
necessary.
Caution
l Do not push the camshaft with the cam so to prevent damage of cam.
Standard end gap: 0.08～0.20mm{0.0031～0.0078in}
Max. end gap: 0.21mm {0.0082in}
Check of tappet
1. Measure the diameter of each tappet hole at two points of A and B shown in Fig,
respectively in the directions X and Y, replace the camshaft when necessary.
Standard diameter: 31.000～31.025mm{1.2205～1.2215in}
