-

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: 82.98-82.99 mm 
Piston marked D: 82.99-83.00 mm 
Piston marked E: 83.00-83.01 mm 
Piston marked G: 83.017-83.032 mm 

-

Oversize

OS1: 83.177-83.192 mm  
OS2: 83.377-83.392 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
