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 to specified torque. Repeat for manifolds.
Fluid cover and manifold fasteners:
90 in-lb (10.2 N•m)
Retorque the air valve fasteners (V) in a crisscross
pattern to specified torque.
Plastic center sections: 55 in-lb (6.2 N•m)
Metal center sections: 80 in-lb (9.0 N•m)
