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: 190to220

in-lb (21 to 25 Nm)

4. Reto

rque the air valve fasteners in a crisscross

patt

ern to the speciﬁed torque.

Air valve fasteners: 45to55in-lb(5to6Nm)

5. Retorque the pilot valves to the speciﬁed torque.

Do not overtorque.

Pilot valves: 20to25in-lb(2to3Nm)
