If fluid cover or manifold fasteners have been
loosened, it is important to torque them using the
following procedure to improve sealing.
NOTE:
NOTE:
NOTE: Fluid cover and manifold fasteners have a
thread-locking adhesive patch applied to the threads.
If this patch is excessively worn, the fasteners may
loosen during operation. Replace screws with new
ones or apply medium-strength (blue) Loctite or
equivalent to the threads.
NOTE:
NOTE:
NOTE: Always completely torque fluid covers before
torquing manifolds.
1.
Start all fluid cover screws a few turns. Then, turn
down each screw just until head contacts cover.
2.
Turn each screw by 1/2 turn or less working in a
crisscross pattern to specified torque.
3.
Repeat for manifolds.
