ASSEMBLY
NOTES
● If exhaust header was removed during service it must be
torqued with the engine rotated in the down position. It is
not possible to reach fasteners on the rear exhaust at the
head with engine rotated in the up position.
● Tighten header nuts gradually, alternating between studs
to insure that exhaust rings are flush with engine. Tighten
fasteners to 72-96 in-lbs (8.1-10.8 Nm).
● If any oil line fittings are found to be loose, or not oriented
in the proper position, those fittings must be removed
and thoroughly cleaned. After cleaning, apply LOCTITE
565 Sealant to the fitting and re-install to the correct ori-
entation. When tightening oil lines, always support the oil
line fitting with a wrench to maintain proper orientation
and prevent damage to the oil line fitting.
