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: 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 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.

Fluid cover and manifold fasteners: 190 to 220 in-lb (21 to 25 Nm)

4.Retorque the air valve fasteners in a crisscross pattern to the speciﬁed torque.

Air valve fasteners: 45 to 55 in-lb (5 to 6 Nm)

5.Retorque the pilot valves to the speciﬁed torque.

Do not overtorque.

Pilot valves: 20 to 25 in-lb (2 to 3 Nm)
