1. Apply compressed air to oil jet valve A and verify
that air passes through oil jet valve B.
• If not ventilation,replace the oil jet valve.
Air pressure:
216—274 kPa {2.2—2.7kgf•cm

PISTON INSPECTION
A6E242411010E01
Caution
•
••
• The piston, piston ring and connecting rod cannot be disassembled.
•
••
• When replacing the piston, piston pin, piston ring and connecting rod, replace them together as a
single unit.
1. Measure the outer diameter of each piston at right
angle 90° to the piston pin, 10.0 mm {0.40 in}
above the under of the piston.
• If the piston diameter is below the standard
diameter, replace the piston, piston pin, piston
ring and connecting rod as a single unit.
Piston diameter
L8:
82.965—82.995 mm {3.2664—3.2675 in}
LF, L3, L3 (with variable valve timing
mechanism):
87.465—87.495 mm {3.4435—3.4446 in}
2. Measure the piston-to-cylinder clearance.
• If not as specified, replace the piston, piston pin, piston ring and connecting rod as a single unit.
Standard clearance:
0.025—0.045 mm {0.0010—0.0017 in}
Maximum clearance:
0.11 mm {0.0043 in}
3. Measure the piston ring-to-ring groove clearance
around the entire circumference.
• If the piston ring-to-ring groove clearance
exceeds the maximum clearance, replace the
piston, piston pin, piston ring and connecting
rod as a single unit.
Standard clearance:
Top: 0.03—0.08 mm {0.0012—0.0031 in}
Second: 0.03—0.07 mm {0.0012—0.0027in}
Oil: 0.03—0.07 mm {0.0012—0.0027 in}
Maximum clearance:
Top: 0.17 mm {0.0067 in}
Second, Oil: 0.15 mm {0.0059 in}
