Installation
Engines А16А2, В16А4, В16А5, В16А6:
Note. Make sure you are using the correct number of guide bushings.
- Piston pin hole diameter: 21 mm
1. Install the piston pin as shown.
Guide sleeve
Other engines:
Installation is done in the same way.
Note. The arrow should point towards the engine drive belt and the connecting rod oil hole should point towards the rear of the engine.
- Piston pin hole diameter: 19 mm
Inspection
1. Measure the diameter of the piston pin.
Engines V16A2, V16A4, V16A5, V16A6:
Piston pin diameter:
- Nominal value: 20.994-21.000 mm
- Extended: 20.997-21.003 mm
Other engines:
Piston pin diameter:
- Nominal value: 18.994-19.000 mm
- Increased: 18,997-19,003
Note: All replacement piston pins are oversized.
2. The zero of the digital indicator of the bore gauge shows the nominal value of the piston pin diameter.
3. Measure the gap between the piston and piston pin.
Note: Check the piston for deformation or cracks.
If the piston pin clearance is greater than 0.024 mm, measure again using an oversize piston pin.
Clearance between piston and piston pin:
- Nominal value: 0.010-0.022mm
4. Check the difference between the piston pin diameter and the smaller connecting rod diameter.
Preload between connecting rod and piston pin:
Engines V16A2, V16A4, V16A5, V16A6:
- Nominal value: 0.013-0.032 mm
Other engines:
- Nominal value: 0.014-0.040 mm
