CAMSHAFT INSPECTION
id011000501500
1. Set the No.1 and No.5 journals of the camshaft on V-blocks.
2. Measure the camshaft runout using the dial gauge.
-
• If it is not within the specification, replace the camshaft.
-
Maximum camshaft runout
-
0.03 mm {0.0012 in}
3. Measure the cam height using the micrometer as shown in the figure.
-
• If it is less than the minimum specification, replace the camshaft.

Standard
IN : 42.44 mm {1.671 in}
EX (MZR 2.0 DISI, MZR 2.0 DISI i-stop) : 41.08 mm {1.617 in}
EX (MZR 2.3 DISI Turbo) : 41.18 mm {1.622 in}
Minimum
IN: 42.34 mm {1.667 in}
EX (MZR 2.0 DISI, MZR 2.0 DISI i-stop) : 40.98 mm {1.613 in}
EX (MZR 2.3 DISI Turbo) : 41.08 mm {1.617 in}
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.
-
Camshaft journal diameter
-
Standard
24.96—24.98 mm {0.9827—0.9834 in}
Minimum
24.95 mm {0.982 in}
5. Measure the camshaft journal oil clearance using the plastigauge with the tappet removed.
-
• If it exceeds the maximum specification, replace the cylinder head.
-
Note
-
• Clean the camshaft journal and the journal receptacle part.
• Cut the plastigauge to the same length as the journal width and position it parallel to the camshaft.
-
Camshaft journal oil clearance
-
Standard
0.04—0.08 mm {0.002—0.003 in}
Maximum
0.09 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.
-
Camshaft end play
-
Standard
0.09—0.24 mm {0.0035—0.0094 in}
Maximum
0.25 mm {0.0099 in}
