Villager V6-181 3.0L SOHC VIN 1 EFI (1997)
The piston pin hole diameter should be within 20.969-20.751 mm (0.8255-0.8258 inch).
Piston - Ring-to -Groove Clearance
Measure the piston ring-to-groove clearance around the entire circumference of the piston with a feeler gauge. The gauge should slide freely around the
entire circumference without binding Any wear that occurs will form a step at the inner portion of the lower ring land.
NOTE: If lower ring lands have high steps, the -piston should be replaced.
-
The standard clearance for the top piston ring is 0.040-0.073 mm (0.002-0.003 inch).
-
The standard clearance for the second piston ring is 0.030-0.063 mm (0.001-0.003 inch).
-
If the piston ring clearance exceeds 0.1 mm (0.004 inch) with a new piston ring replace the piston.
Piston Pin Fit
1. Use a telescoping gauge to measure each piston pin hole diameter as shown.
The piston pin hole diameter should be within 20.969-20.975 mm (0.8255-0.8258 inch).
