NOTE:
Fluid cover and manifold fasteners have a
thread-locking adhesive patch applied to the threads. If
this patch is excessively worn, the screws 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 proce-
dure 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:
100 in-lb (11.3 N•m)
Retorque the air valve fasteners (V) in a crisscross pat-
tern to specified torque.
Air valve fasteners:
55 in-lb (6.2 N•m) for
plastic center sections
80 in-lb (9.0 N•m) for
metal center sections
