Needle Shaft Pack Reassembly
1. Install pusher seal, rear u-cup, rear spreader
seal, front u-cup seal, front spreader seal as shown.
Orient seals per Figures 41 and 43.
2. Install jam nut all the way on the shaft. Install
the carbide ball all the way down using two 74133
tools. Tighten the jam nut against the carbide ball.
Needle Shaft Rebuild
1. Prior to installing the needle shaft, partially fill
the internal bore of barrel with dielectric grease.
2. Fill the inner diameter of the packing tube with
dielectric grease.
3. Insert the needle shaft, rear section first, into
the packing tube. Rotate the needle shaft while
moving back and forth inside the packing tube
until fully inserted.
4. With your finger, wipe the excess grease from
both ends of the packing tube. Using the excess
grease, apply a thin film to the outer surface of
the packing tube and to the external o-ring on the
cartridge seal.
5. Apply a light film of dielectric grease to the seal
retainer o-ring and install it into the external groove.
Reinstall Needle Shaft/Barrel
1. Push needle shaft assembly straight into the
barrel. Apply LSCH0009-00.
† Be generous with the dielectric grease
when applying it to the packing tube and
needle shaft. This helps to remove air
voids from this chamber. DO NOT apply
so much grease that it creates an air lock
during assembly of the applicator.
