Torque Instructions

Maintenance

NOTE: All fasteners for the ﬂuid covers, center diaphragm joint, and manifolds 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, center diaphragm joint, or manifold fasteners have been loosened, it is important to torque them using the following procedure to improve sealing.

NOTE: Always completely torque the ﬂuid covers and center diaphragm joint before torquing the manifolds.

Start all ﬂuid cover or center diaphragm joint 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, center diaphragm joint, and manifold fasteners: 100 in-lb (11.3 N•m)

Lubricate air valve fasteners prior to reassembly to prevent galling. Retorque the air valve fasteners in a crisscross pattern to speciﬁed torque.

Air valve fasteners: 80 in-lb (9.0 N•m)
