Reassemble the Module
See Figure 10.
1. Lubricate a new O-ring (5) with Parker Hi-Temp lubricant (P/N 900493) and install it in
the groove in the top of the module body.
CAUTION: Failure to screw the guide tube fully into the module body will result
in damage to the armature and seat due to lack of stroke clearance.
2. Lubricate the top threads of the guide tube (8) with high temp silicone. Carefully pass
the top threads through the O-ring by rotating it clockwise. Push the guide tube through
until the threads engage, and screw the guide tube fully into the module body.
3. Install the spring (9), armature (10), O-ring (11), and seat (12). Lubricate the O-ring
Parker Hi-Temp lubricant (P/N 900493).
4. Install the coil and housing assembly (2) on the module body, slipping it over the guide
tube. Note the location of the coil pins (4).
5. Install the retaining nut (1).
6. Lubricate and install the module body O-ring (7) with Parker Hi-Temp lubricant (P/N
900493). Replace the O-ring if the existing one is worn or damaged.
7. Ensure that the coil pin seal (3) is in place.
8. Install the module on the gun. Refer to Install a Module under Replacing a Module.
Replace the Coil Connector
Follow this procedure to replace the electrical connector (terminal block) for the module coil.
Refer to Parts for the coil connector kit part number.
1. De-energize the system and disable the gun. Refer to Safety.
2. Remove the module from the gun. Refer to Remove a Module under Replace a Module.

the connector will result.
4. Remove the manifold cover and gasket. If the gasket is broken, replace it.
5. Loosen the connector socket screws and remove the wires.
