Ed,

Sure looks familar.......I spent the day = taking=20 a 89-91 core engine apart

to recover one good 9.7 to 1 rotor......Other rotor suffered apex = seal=20 failure

(stock 3 piece seals).......Rotor looks alot like = yours.......Rotor hsgs=20 are shot

.......End hsgs serviceable but should probably be = lapped.......It has=20 taken

two core engines to get two good 9.7 rotors.......Such is life = !!
