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 verify that exhaust rings are flush with engine. Tighten
fasteners to 72-96 in-lbs (8.1-10.8 Nm).
1. When repairs have been completed, rotate engine back
up into frame.
NOTE
When installing and tightening isolator bolt it is important to
keep load off of isolator bolt for installation purposes. Alternate
between tightening isolator bolt and raising engine with scissors
jack.
