V70R AWD L5-2.3L Turbo VIN 52 B5234T6 (1998)
-
Lower compression ring: 1.75 mm
-
Oil scraper ring: 3.0 mm
6. Measure piston diameters:
-
Use micrometer tool No. 999 9704, or equivalent and sliding calipers.
-
A = Overall piston height.
-
B = Height from wrist pin center to crown.
-
C = Piston diameter must be measured at right-angles to wrist pin hole and at distance C from edge of skirt.
-
D = Diameter.
-
Dimensions A, B and C, see table.
Piston diameter: (D)
-
Standard
Piston marked C: 80.98-80.99 mm
Piston marked D: 80.99-81.00 mm
Piston marked E: 81.00-81.01 mm
Piston marked G: 81.017-81.032 mm
-
Oversize
OS1: 81.177-81.192 mm
OS2: 81.377-81.392 mm
NOTE: Max. difference in weight between pistons in same engine: 10 g
7. Calculate piston clearance:
-
Measured:
Cylinder diameter minus Piston diameter = Piston clearance.
Permissible piston clearance: 0.01-0.03 mm
NOTE: Measurement of cylinder bore as per steps 1 through 3 of Cylinder Block, Measurement. See: Service and Repair
