(4) Repeat the procedures for each remaining valve
spring to be removed.
(5) Install the push rods. Ensure the bottom end of
each rod is centered in the plunger cap seat of the
hydraulic valve tappet.
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.
• 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.).
