Piston and Connecting Rod Disassemble (1.6L LLU)



1. Remove the piston with connection rod. Refer to Piston, Connecting Rod, and Bearing Removal .

2.
Note

Note installation position of the piston in respect of the connection rod.


Detach the piston from the connection rod.


• Remove the retainer (1) from the piston eye.

• Do not damage the bore.

• Press the piston pin out of the piston.

3. Remove the piston rings using piston ring pliers (1).

Remove oil carbon from the groove with a split piston ring, filed to a wedge-shape.


4. Measure the piston ring gap.


• Tension the piston ring in the cylinder and measure the gap with a feeler gauge.

• Permissible ring gap:

- Rectangular compression ring (1): 0.20-0.35 mm (0.007-0.014 in)

- Tapered compression ring (2): 0.35-0.50 mm (0.014-0.020 in)

- Oil scraper ring (3): 0.20-0.90 mm (0.007-0.036 in)

5. Check piston ring vertical play with a feeler gauge (1) in the piston ring groove.

Permissible vertical play:



• Rectangular compression ring (1): 0.015-0.070 mm (0.0006-0.0028 in)

• Tapered compression ring (2): 0.03-0.07 mm (0.001-0.002 in)

• Oil scraper ring (3): 0.04-0.12 mm (0.0016-0.0048 in).
