Diagnostic Procedure (Cont'd)
EC-1144

IDLER GEAR OIL CLEARANCE
+Measure the inner diameter (d1) of idler gear shaft hole.
Standard: 26.000 - 26.020 mm (1.0236 - 1.0244 in)
+Measure the outer diameter (d
2) of idler shaft.
Standard: 25.967 - 25.980 mm (1.0223 - 1.0228 in)
+Calculate gear clearance.
Clearance = d
1þd2Standard: 0.023 - 0.053 mm (0.0009 - 0.0021 in)
Installation
1. Install cylinder head gasket.
+Cylinder head gasket to be installed is selected by its thick-
ness through the following procedure.
When replacing gasket only
+Install gasket with same thickness as the one removed.
+Gasket thickness is identified by the number of notches
located on rear-left side.
GradeGasket thickness*
mm (in)No. of notches
1 0.65 (0.0256) 1
2 0.70 (0.0276) 2
*: Thickness of gasket tightened with head bolts
+The number of notches can be checked at the position
shown in the figure before cylinder head is removed. (It is
necessary to remove exhaust manifold.)
When repairing/replacing the following
+When the top of cylinder block or crankshaft pin/journal is
ground, or
+When cylinder block, piston, connecting rod, or crankshaft is
replaced
1) Move piston toward TDC.
2) Position dial indicator on cylinder block as shown in the
figure, and adjust the needle to ª0º.
3) Move dial indicator stand aside, and position the dial indica-
tor to the measuring point as shown in the figure.
4) Rotate crankshaft slowly, and read the value on dial indica-
tor at piston's maximum height.
5) Repeat above procedure at 2 positions of each cylinder (8
positions in total for 4 cylinders), and select the appropriate
gasket by comparing the maximum crown depression with
the table.
