244G6 – PISTONS CONNECTING RODS
Inspection
Piston rings
1. Check the clearance between the piston rings and the piston grooves.
If it exceeds the clearance limit value, replace the piston ring, or both
the piston ring and the piston.
Standard values :
No. 1 0.03 – 0.07 mm
No. 2 0.02 – 0.06 mm
Limit value : 0.1 mm
2. Insert the piston ring and the side rail of the oil ring into the cylinder
bore, and press in using the top surface of the piston. After reaching
a right-angle position, measure the opening gaps in the rings using a
thickness gauge.
Remark :
Press the openings of the piston ring and the oil ring side rail with the
piston in the position shown in the diagram, and measure the opening
gaps in this position.
Standard value
No. 1 0.20 – 0.30 mm
No. 2 0.35 – 0.45 mm
Oil ring 0.10 – 0.40 mm
Standard value
No. 1 0.8 mm
No. 2 0.8 mm
Oil ring 1.0 mm
