When blanking plug 145 is fitted in third opening 110, the bore is axially aligned with and opens onto the second opening. A threaded fixing means is fitted through the second opening to engage in the bore, fixing the first and second casings. The blanking plug may also have recesses 143 engageable by a locking pin spanner. Blanking plug 145 may provide access to an oilway, electrical connection or core plug. |
