Torque Instructions
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 N m)
5. Retorque the pilot valves to the specified torque.
Do not overtorque.
Pilot valves: 20 to 25 in-lb (2 to 3 Nm)
