3. The one piston rod seal can be removed after first unscrewing the Packing nut (PAT-
LS-1006).
4. Before replacing the new seals ensure that the entire housing is clean. Lightly grease
the seal housing and packing nut thread section. Check also the rod bushing (PAT-LS-
1005) for wear and damage and replace as necessary.
5. The seals must be pushed into the housing evenly. A simple way by which the new
seals can be installed is by first placing one seal (Lip down) into the outlet body so that it
rests horizontal. Now the packing nut can be screwed down upon the seal by hand which
will progressively push the first seal down with an even parallel force. Once screwed by
hand as far as possible, unscrew the packing nut and repeat this exercise with the second
seal (lip down).
6. Finally back off and retighten the packing nut so that it just makes contact with the
seals which are now firmly in their housing bottom position.

7. Withdraw the piston assembly from the lower intake body and place aside taking care
not to drop or damage the high tolerance surfaces of the rod or larger piston diameter.
8. The piston seal (PAT-LS-1014) can be removed after lifting out the bush (PAT-LS -
1013).
9. Ensure the new seal is placed inside the lower intake body with the O ring lip seal
upper most as indicated. Also note the bush must be placed on top of the seal with the
wider edge down as indicated. Fit the O ring (0-E-035) over the bush before inserting the
piston and re assembling the upper outlet body.
