2. RELEASE
3. INLET
4. PISTON RINGS. Replacement (see below). Measurement (see below).
5. PISTON. Examination (see below)
Note: Before removing the pistons, check to see if the top of the cylinder has a carbon ring. If necessary, remove soot.
6. CYLINDER BLOCK. Cylinder check (see below). Warping check (see below). Cylinder honing (see below)
7. Before removing the piston, check to see if an annular protrusion from soot has formed in the upper part of the cylinder. If necessary, remove soot.
8. CONNECTING ROD CAP NUT, 8x0.75 mm, 31 Nm (3.2 kgf/m). Apply engine oil to the nut threads.
Note: After tightening each bearing cap, turn the crankshaft to make sure it does not bind.
