Inspecting the small end

- Using a bore gauge, measure the connecting rod

small end diameter.

N.B.

IF THE CONNECTING ROD SMALL END DIAMETER EX-
CEEDS THE STANDARD DIAMETER, EXHIBITS WEAR OR
OVERHEATING, PROCEED TO REPLACE THE CRANK-
SHAFT AS DESCRIBED IN THE CRANKCASE AND
CRANKSHAFT CHAPTER.

Characteristic

Standard diameter:

22 + 0.025 +0.015 mm

Inspecting the wrist pin

- Check the pin outside diameter using a micrometer.

Characteristic

Standard diameter:

22 0 -0.004 mm

- Calculate the coupling clearance between pin

and connecting rod end.

Characteristic

Standard clearance:

0.015 ÷ 0.029 mm

Inspecting the piston

- Measure the diameter of the bearings on the pis-

ton.

Characteristic

Standard diameter:

22 + 0.006 + 0.001 mm

- Calculate the piston pin coupling clearance.
