Disassembling the piston-connecting rod assembly [Toyota Camry Vista-V40]

1. Check the fit of the piston-piston pin joint by trying to move the piston back and forth on the piston pin in a direction perpendicular to the axis of the piston pin. If there is noticeable play, replace the entire assembly.



2. Remove the piston rings.

a) Special tools (with an expander or a screwdriver) remove both compression rings.



b) Remove the oil scraper ring elements manually (scrapers and ring expander).

Note: Place the rings in the correct order.

3. Disconnect the connecting rod from the piston.

a) Using a screwdriver, remove the retaining rings.



b) Gradually heat the piston to a temperature of 80 - 90°C.

c) Using a plastic-headed hammer and a copper rod, knock out the piston pin and remove the connecting rod.

Note:

• If necessary, place marks on the piston and connecting rod to ensure correct assembly.
• Do not disassemble the piston and piston pin.
• Lay out the piston group parts in sets.
