blocking the spring follower and allowing the seal face to unload. This caused a I

.i2#I i-l:1 l cradual loss of the closed cycle mal water inventory. The seal was replaced and l t i:1 I the retainer lubricated. The nunp returned to service on 5/28/81 at 2022 hours0.0234 days <br />0.562 hours <br />0.00334 weeks <br />7.69371e-4 months <br />.
