1D-30 Engine Mechanical:
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)
(B): 09900–22302 (Plastigauge)
3) Install the cylinder head cover.
4) Tighten the cylinder head cover bolts evenly and
diagonally to the specified torque. Refer to “Engine
Top Side Assembly (Page 1D-22)”.
NOTE
Do not rotate the camshafts with the
plastigauge in place.
Tightening torque
Cylinder head cover bolt: 10 N·m (1.0 kgf-m, 7.0
lbf-ft)
5) Remove the cylinder head cover and measure the
width of the compressed plastigauge using the
envelope scale.
6) This measurement should be taken at the widest
part of the compressed plastigauge.
Camshaft journal oil clearance
Service limit: 0.150 mm (0.0059 in)
7) If the camshaft journal oil clearance exceeds the
limit, measure the inside diameter of the camshaft
journal holder and the outside diameter of the
camshaft journal. Replace the camshaft or the
cylinder head depending upon which one exceeds
the specification.
Special tool

(D): 09900–22403 (Small bore gauge (18 –
35 mm))
