15. Install the compression rings so the letter on the
top surface of each ring faces the dome of the
piston. Rotate the rings until the ring end gaps are
no less than 90° from one another.
16. Install the connecting rod bearings into the
connecting rods; then using a ring compressor and
a soft dowel (wood or plastic), lubricate each
piston and cylinder thoroughly with engine oil and
slide each piston into the cylinder and over the
connecting rod journals. Make sure the arrow on
the top of the piston is facing toward the timing
chain end of the crankcase.

NOTE: To aid in guiding the connecting rod to
the journal on the crankshaft, install two pieces of
fuel hose (approximately 12 cm or 5 in.) to the
studs on the end of the connecting rod.

rod studs; then seat the connecting rods over the
connecting rod journals.

NOTE: Make sure the tabs and the oil holes in
the connecting rod bearings are aligned with the
notches and oil passages in the connecting rods.
Keep the connecting rods and connecting rod
caps in their appropriate pairs by aligning the
matching letters on the sides of the connecting
rod/connecting rod cap pairs.
18. Place a small piece (about the width of the
bearing) of Plastigauge onto the face of the
connecting rod journal for all three connecting
rods. Place the connecting rod bearings into
position.
„
NOTE: Make sure the identification numbers
stamped on the side of the connecting rod caps
and the “V” arrow on the top of the connecting rod
caps are facing the timing chain end of the crank-
case. The “V” arrow should be on the same side as
the oil squirter boss.
