Divorced Section (10) from the bottom and push up
carefully through the U-cup seal (8).
7. Install the Seal Cup (12) into the Divorced Section
(10) over the Metering Rod (11) and slide the lubri-
cated Posipak Seal (13) over the Metering Rod
keeping the O-ring side of the Posipak facing down.
The ends of the Metering Rod (11) should be pro-
jecting from the upper and lower ends of the
Divorced Section.
8. Lubricate the dispense sleeve bore in the Main
Body (27). Insert the Dispense Sleeve (14) into the
Main Body (27). Check for threads that may be in
the inside of the sleeve due to tapping during
removal and make sure these are at the top.
