Service Procedure
!
Caution: Disconnect electrical supply to the unit. Shut off
air supply and exhaust pressure trapped within the unit
before servicing.
Servicing Valve & Solenoid Assemblies:
Remove the four mounting screws to detach the solenoid cover
assembly from the solenoid conduit plate. Lift the solenoid cover off
from the conduit plate. Be careful not to lose the plunger return
spring or the thrust washer. The plate is removed from the valve
body assembly by removing 4 flat head screws. To remove the
spool, spool guides, and seals from the body, either remove the
remaining conduit plate (double solenoid) or remove the end plate
(single solenoid). The end plate is secured to the body with four flat
head screws (not shown in figure). Gently press or pull on the
spool’s “pin” until the spool slides out of the body. The spool guides
may be removed by pulling axially on the radial holes drilled in the
spool guide. Be careful not to scratch the sealing surfaces or cut the
seals.
Thoroughly clean the valve body bore and spool guides, and inspect
for possible nicks, scratches, and material imperfections. Lightly
lubricate the spool’s sealing surfaces using a non-detergent hydro-
carbon based oil or grease. Replace any o-rings or other seals if
they are damaged. See Service Kits & Parts Available section.
Assembly of unit is the reverse of disassembly. (It is best to position
the solenoid in its up-right position on the conduit plate and then
place the solenoid cover over the solenoid.) Apply from 1.1 to 1.4
Nm (10 to 12 in-lb) of torque to the flat head screws, and tighten the
pan head mounting screws from 1.7 to 2.0 Nm (15 to 18 in-lb) of
torque. If body is removed from base, torque mounting screws to
11.3 to 14.1 Nm (100-125 in-lb) of torque when reassembling.
If you have questions concerning how to service this unit, contact
your local authorized dealer or your customer service representative.

Maintenance & Trouble Shooting Hints
Noisy Solenoid:
1.
Check voltage and hertz ratings of main electrical source. This
must agree with the solenoid rating.
2.
Inspect solenoid plunger bar and mating frame laminations for
damaged contact surfaces, and dirt particle contamination.
3.
Check solenoid holddown spring for distortion, deterioration,
and excessive wear.
4.
Check spool for peened and/or flared condition.
5.
Check solenoid plate, and solenoid cover mounting screws for
looseness.
Air Leakage Through Exhaust Ports:
1.
Check for internal leakage in cylinder being operated by valve.
2.
Check spools’s center sealing surfaces for nicks, cracks, peeling
and/or delamination.
3.
Check for missing, damaged, swollen, or incorrectly assembled
o-rings and gaskets.
4.
Check spool guide and body bore for nicks, scratches, and dirt
particles.
5.
Check body to base gaskets for damage or improper assembly.
Replace worn or damaged parts. Reassemble and test unit.
