Module Assembly Instructions for the PN 110840 Horizontal SB and PN 111074
Vertical SB UFD Modules
Demount the module from the service block, refer to the instructions in Chapter 5.6
Replacement of Standard Module on previous pages.
Use the component illustrations and parts lists in Chapter 7 as a reference with the
following instructions for the PN 110840 & 111074 SB UFD modules. ITW Dynatec has a
Module Rebuild Kit available (PN 110889) which contains the components necessary to
rebuild one module, including the valve cartridge assembly and O-rings.
1. Disassemble the UFD SB module. Discard the old valve cartridge and thoroughly
clean the remaining parts.
2. Lightly coat the O-rings on the new valve cartridge (included in the kit and shown
above) with a high-temperature lubricant, such as PN 001U002 Dow 112 or PN
001V078 Krytox GPL206.
Note: Take care to keep lubricant off of the air piston lip seals.
CAUTION
DO NOT SUBSTITUTE! Failure to use High Temp Lube (N07588) may result in
premature seal breakdown and leakage of glue from the Applicator!
3. Carefully install the new valve cartridge into the SB module body, pushing it in until it
is firmly seated.
4. Making sure that the air cylinder and piston lip seals are clean and dry, carefully install
the air cylinder over the piston and onto the valve cartridge.
5. Align the air cylinder’s external O-ring with the three external O-rings in the SB
module’s body.
6. Secure the air cylinder with the four M3 x 35mm long cap screws dis-assembled in
step 1.
7. Torque the cap screws cross-wise to 20 inch-lb. (2.3 NM).
8. Install new external o-rings (included in kit) on the SB module with a minimal coating
of high-temp lubricant.
The module is now ready for installation and service.
To disassemble, reverse above order.
