4. Measure the journal diameter using the
micrometer. Measurement positions total four and
are in the X and Y directions, at two points (A and
B) as shown in the figure.
•
If it is less than the minimum specification,
replace the camshaft.
Standard camshaft journal diameter
24.96—24.98 mm {0.9827—0.9834 in}
Minimum camshaft journal diameter
24.93 mm {0.9815 in}
5. Measure the camshaft journal oil clearance using
the following procedure:
(1) Clean the camshaft journal and the journal receptacle part.
(2) Put the camshaft on the cylinder head with the rocker arm detached.
(3) Cut the plastigauge to the same length as the
journal width and position it parallel to the
camshaft.
(4) Install the camshaft caps. (See 01-10-59
CYLINDER HEAD ASSEMBLY (II).)
(5) Remove the camshaft caps. (See 01-10-14
CYLINDER HEAD DISASSEMBLY (I).)
(6) Measure the camshaft journal oil clearance.
•
If it exceeds the maximum specification,
replace the cylinder head.
Standard camshaft journal oil clearance
0.035—0.080 mm {0.0014—0.0031 in}
Maximum camshaft journal oil clearance
0.090 mm {0.0035 in}
6. Measure the camshaft end play using a dial
gauge.
•
If it exceeds the maximum specification,
replace the cylinder head or camshaft.
Standard camshaft end play
0.07—0.22 mm {0.003—0.008 in}
Maximum camshaft end play
0.23 mm {0.0091 in}
