Torque Torque Instructions
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: Always completely torque fluid covers before
NOTE: NOTE:
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.

4. Retorque the air valve fasteners in a crisscross
pattern to the specified torque.
Air valve valve fasteners: fasteners: 45 to 55 in-lb (5 to 6 Nm)
