Torque Instructions
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.
If fluid cover or manifold fasteners have been
loosened, it is important to torque them using
the following procedure to improve sealing.
NOTE: Always completely torque fluid covers
before torquing manifolds.
Start all fluid cover screws a few turns. Then
turn down each screw just until head contacts
cover. Then turn each screw by 1/2 turn or less
working in a crisscross pattern until each
screw is torqued to 100 in-lb (11.3 N•m).
Repeat for manifolds. See FIG. 7.
Retorque the air valve fasteners (V) in a criss-
cross pattern to specified torque.
Plastic center sections: 55 in-lb (6.2 N•m)
Metal center sections: 80 in-lb (9.0 N•m)
