Specifications

(10) Side bolts (M1-M2): Tighten M1 bolts to 30
N·m, then rotate them 85° (65). Tighten M2 bolts to
30 N·m, then rotate them 85° (65).
NOTE: If vehicle is equipped with A/C do not install
A/C lines to compressor and charge A/C till Phase 2
is complete.
(11) 2nd Phase: After 20 minutes of engine oper-
ation at operating temperature, allow engine to cool
down completely. Then retorque the head bolts as fol-
lows:
(12) Central bolts A-L: Completely back off bolts
one-by-one and then retighten to 30 N·m plus 130°
(65°). Then proceed in the same way, bolt by bolt,
following alphabetical order, as indicated.
(13) Side bolts M1-M2: Without slackening ,
torque bolts M1 then bolts M2 to 90 N·m (66 ft. lbs.).
(14) Torque intake nuts to 28 N·m (20 ft. lbs.) and
exhaust manifolds nuts to 32 N·m (24 ft. lbs.) after
completing the cylinder head torquing procedure.
(15) Install the oil feed lines for the rocker arm
assemblies. Torque oil feed lines to 13 N·m (115 in.
lbs.) (Fig. 69).
(16) Install the oil feed line support bracket at
rear of the cylinder head (Fig. 70). Torque bolt to 5.5
N·m (4 ft. lbs.).
(17) Install the push rods. (Fig. 71).
WARNING: During the installation of the rocker arm
assemblies it is possible to cause valve interfer-
ence between the piston and valve if the piston is
near Top Dead Center (TDC). This is due to the slow
bleed down rate of the tappets when adjusting the
rocker arm assemblies. Follow the procedure below
to ensure that engine damage does not occur.
• Install the rocker arm assemblies in the same
order as removed (Fig. 71).
• Bring piston#1toTopDead Center.
• At this point tighten the rocker arm nuts for cyl-
inder # 2–3–4–5. Torque nuts to 27 N·m (20 ft. lbs.).
• Slowly rotate the crankshaft 90° clockwise or
counterclockwise, then tighten the rocker arm nuts
for cylinder # 1. Torque nuts to 27 N·m (20 ft. lbs.).
(19) Install the cylinder head cover. Torque bolts to
15 N·m (133 in. lbs.) (Fig. 72).
(20) Connect the crankcase breather hose to front
of cylinder head cover.
(21) Connect the injector sensor wire and the glow
plug hot lead.
(22) Install the turbocharger oil feed line. Torque
banjo bolts to 27 N·m (20 ft. lbs).
(23) Install the turbocharger oil return line.
Torque bolts to 11 N·m (97 in. lbs.) .
(24) Install the water manifold. Torque bolts to 12
N·m (106 in. lbs.).
(25) Raise the vehicle on hoist.
(26) Install the exhaust pipe to turbocharger.
Torque bolts to 32 N·m (23 ft. lbs.).
