HINT:
If the location of this area cannot be judged by visual inspection,
measure the outer diameter at the location shown in the illustra-
tion.

If the outer diameter is less than minimum, replace the connect-
ing rod and rod cap nut as a set.

− CYLINDER BLOCK
Check the piston pin fit at normal room temperature. Coat
the piston pin with engine oil, and push it into the connect-
ing rod with your thumb.
INSPECT CONNECTING ROD BOLTS
Install the cap nut to the connecting rod bolt. Check that
the rod cap nut can be turned easily by hand to the end
of the thread.
If the cap nut cannot be turned easily, measure the outer
diameter of the compressed thread with vernier calipers.
Standard outer diameter:
7.860 − 8.000 mm (0.3094 − 0.3150 in.)
Minimum outer diameter: 7.600 mm (0.2992 in.)
CYLINDER BORING
Bore all the 6 cylinders for the oversized piston outside di-
ameter.
Replace all the piston rings with ones to match the over-
sized pistons.
Keep the oversized pistons.
Oversized piston diameter:
O/S 0.50: 93.856 − 93.886 mm (3.6951 − 3.6963 in.)
Calculate amount to the bore cylinders.
(1) Using a micrometer, measure the piston diameter at
right angles to the piston pin center line, 26 mm
(1.02 in.) from the piston head.
