Repair procedure for an amplifier head leak
The Delrin thrust washer compresses the silicone Oring around the amplifier rod when the retaining nut is tightened by using the appropriate spanner wrench ( there are two spanner wrenches: one for tightening the Oring seal and one for clocking the rod). There is a chance that a water leak can be stopped by tightening the retaining nut, but it is more likely that a new thrust washer and/or silicone Oring need to be retrofitted.
Tightening the rod Oring compression without replacing the Delrin thrust washer/silicone Oring
- Remove key from LSS
2. Verify LCS water is not flowing
3. Insert spanner wrench designated for Orings into end of laser head and turn clockwise with low to medium pressure (do not over tighten). If the retaining ring does turn then there is a chance that tightening might be enough to stop leak.
4. Return to normal operation and test by first looking for any water seepage near end of rod that was tightened. If no, proceed to firing only the laser head that was tightened. Confirm that the head is either sealed or leaking by using the test optic technique described above in the "Not so obvious signs of a problem" section.
