Bolting Liners Down

IMPORTANT: Do not rotate crankshaft with cylinder
head removed unless liners are bolted
down. Bolt liners down before removing
piston.
Cap screws and washers must be
tightened to 68 N•m (50 lb-ft) to achieve
an accurate reading when checking
liner standout (height above block), as
detailed later in this group.
5. Use seven M16 x 2.0 x 55 mm (2.17 in.) long cap
screws (A) and 5/8 in. ID x 1-3/4 in. OD x 3.18 mm
(1/8 in.) thick washers (B) to bolt down cylinder liners
(C) in the seven locations as shown. Tighten cap
screws to specifications.

6. Before removing pistons, visually inspect condition of
cylinder liners with pistons at bottom dead center
“BDC”. Liners will require replacement if:
• The crosshatch honing pattern is not visible
immediately below the top ring turn-around area.
• Liners are pitted or contain deep vertical scratches
that can be detected by the fingernail.
No further inspection is required if any one of the
above conditions is found.
