(6) Push the piston, connecting rod assembly, and upper bearing through the top of the
cylinder block.
HINT
• Keep the bearing, connecting rod, and cap together.
• Arrange the piston and connecting rod assemblies in the correct order.
(7) Repeat for the other 3 piston/connecting rod assemblies.
F. Remove the connecting rod bearings.
HINT
Arrange the removed parts in the correct order.
G. Inspect the cylinder bore for abnormal damage.
Visually check the cylinder bore for the presence of crosshatch.
• If the cylinder bore has visible crosshatch, the cylinder block is OK to re-use.
• Confirm that only light vertical marks are present, if any.
NOTE
• It is normal for an in-service block to have light markings present from carbon and
should NOT be interpreted as excessive cylinder wall scratches.
• ONLY replace the short block if multiple, severe scratches are present.
• Do NOT hone the cylinder walls.
H. Using a screwdriver, pry out the 2 piston pin
hole snap rings.

2AZ Engine Oil Consumption Repair Procedure
Repair Procedure (Continued)
I. Remove the piston.
(1) Gradually heat the piston to
approximately 176◦ to 194◦F
(80◦ to 90◦C).
Figure 17.
HINT
If necessary, sublet the following
specialized and precision operations
to a local engine machining shop.
(2) Using a plastic hammer and brass bar,
lightly tap out the piston pin and remove
the connecting rod.
Figure 18.
NOTICE
• The piston, pin and connecting
rod are a matched set.
• Arrange the pistons, pins, rings,
connecting rods, and bearings in
the correct order.

4. Inspect piston, pin, connecting rod and bearings to determine replacement part numbers and
measure to determine if parts are suitable for re-use.
NOTE
The following steps are required to determine the correct replacement part numbers.

(1) Using a micrometer, measure the piston
pin diameter.
Figure 20.
Standard Piston Pin Diameter: 21.997 to
22.006 mm (0.8660 to 0.8664 in.)
Ensure the connecting rod small end
bore diameter measurement is within
specification for the piston bore diameter
mark inspected previously. If the
diameter is NOT as specified, replace
the piston pin.

NOTE
Piston pin type is a matched set with
the piston and connecting rod. For
example: if the piston removed has a
"B" marking, the piston pin diameter
should be 22.001 - 22.003 mm

Using vernier calipers, measure the tension
portion diameter of the bolt.
Standard Diameter: 7.2 to 7.3 mm
(0.283 to 0.287 in.)
Minimum Diameter: 7.0 mm (0.276 in.)
If the diameter is less than the minimum,
replace the connecting rod bolt.
