Part 2 of 2
Piston And Rings1. Clean piston
(1) Using a gasket scraper, remove the carbon from the piston top.
(2) Using a groove cleaning tool, clean the piston ring grooves.
(3) Using solvent and a brush, thoroughly clean the piston.
NOTE:
Do not use a wire brush.
2. The standard measurement of the piston outside diameter is taken 12mm (0.4724in.) from the bottom of the piston.
Standard diameter
95.96 - 95.99mm (3.7779 - 3.7791in.)
3. Calculate the difference between the cylinder bore diameter and the piston diameter.
Piston-to-cylinder clearance :
0.03 - 0.05mm (0.0012 - 0.0020in.)
4. Inspect the piston ring side clearance.
Using a feeler gauge, measure the clearance between new piston ring and the wall of the ring groove.
Piston ring side clearance
Standard
No.1 : 0.04 - 0.08mm (0.0016 - 0.0031in.)
No.2 : 0.04 - 0.08mm (0.0016 - 0.0031in.)
Oil ring : 0.02 - 0.065mm (0.0008 - 0.0026in.)
Limit
No.1 : 0.1mm (0.004in.)
No.2 : 0.1mm (0.004in.)
Oil ring : 0.2mm (0.008in.)
If the clearance is greater than maximum, replace the piston.
5. Inspect piston ring end gap.
To measure the piston ring end gap, insert a piston ring into the cylinder bore. Position the ring at right angles to the cylinder wall by gently pressing it down with a piston. Measure the gap with a feeler gauge. If the gap exceeds the service limit, replace the piston ring. If the gap is too large, recheck the cylinder bore diameter against the wear limits. If the bore is over the service limit, the cylinder block must be replaced.
Piston ring end gap
Standard
No.1 : 0.17 - 0.32mm (0.0067 - 0.0126in.)
No.2 : 0.32 - 0.047mm (0.0126 - 0.0185in.)
Oil ring : 0.2 - 0.5mm (0.0078 - 0.0196in.)
Limit
No.1 : 0.6mm (0.0236in.)
No.2 : 0.7mm (0.0275in.)
Oil ring : 0.8mm (0.0315in.)
Piston Pins
1. Measure the diameter of the piston pin.
Piston pin diameter :
21.097 - 22.000mm (0.8305 - 0.8661in.)
2. Measure the piston pin-to-piston clearance.
Piston pin-to-piston clearance :
0.004 - 0.013mm (0.00016 - 0.00051in.)
3. Check the difference between the piston pin diameter and the connecting rod small end diameter.
Piston pin-to-connecting rod interference :
0.005 - 0.019mm (0.0002 - 0.0007in.)
