5. To rebuild, insert new seals (9) in the seal holder (8), taking care to insure they
are oriented in the same manner as the ones that were removed. Do not reuse
seals that have been removed from the pump. Replace the seal retainer gasket
(11) if it shows signs of deformation or damage.
6. Wrap tape or other material over the exposed piston rod threads to protect the
new seal lips from damage. Install the seal retainer gasket then slide the seal
holder over the protected threads and into the pump frame. Care must be taken
to insure the seal lips are not folded or cut when passing over the ends of the rod.
7. On L09 through L16 insure that the gasket (11) and seal holder (8) are in place,
install the seal retainer (10) and tighten until it bottoms out. Do not overtighten as
it can damage the seal retainer gasket. For L06 pumps, apply silicone gasket
compound to the rear face of the seal holder, slide over the rod as described
above, and press fit into the power frame (1) bore.
8. Remove the protective material that is covering the rod threads. Rebuild the
remainder of the pump as outlined in previous sections. Torque all fasteners as
outlined in the Fastener Torque Requirements, Section 11.0, of this manual.
