to match the side faces of the connecting rod. Ensure
all sharp edges are removed, and loose chippings

sembly into the engine.

the connecting rod using a 4.6 mm (0.187 in) bit. Drill
through the existing oil hole, Fig. 3.

tion. Remove burrs, and chippings, before refitting.

nents with engine oil. Assemble the connecting rod,
and piston, with the letter or grade mark on the pis-
ton, aligned to the pip (1), Figure 4, on the connecting
rod. Install the piston pin and retainers.
