Engine Mechanical: 1D-23
Camshaft Runout
Measure the runout using the dial gauge. Replace the
camshaft if the runout exceeds the limit.
Special tool
(A): 09900–20606 (Dial gauge (1/100 mm))
(B): 09900–20701 (Magnetic stand)
(C): 09900–21303 (V-block (75 mm))
Camshaft runout (IN & EX)
Service limit: 0.10 mm (0.004 in)
Camshaft Journal Wear
Inspect the camshaft journal wear in the following
procedures:
1) Determine whether or not each journal is worn down
to the limit by measuring the oil clearance with the
camshaft installed in place.
2) Use the plastigauge to read the clearance at the
widest portion, which is specified as follows.
Special tool
(A): 09900–22301 (Plastigauge (0.025 –
0.076 mm))
3) Install the camshaft journal holder. Refer to “Engine
Top Side Assembly (Page1D-18)”.
NOTE
Do not rotate the camshafts with the
plastigauge in place.
Tightening torque
Camshaft journal holder bolt: 10 N·m (1.0 kgf-
m, 7.0 lb-ft)
4) Remove the camshaft journal holder and measure
the width of the compressed plastigauge using the
envelope scale. This measurement should be taken
at the widest part of the compressed plastigauge.
