The seal, part # 63718-zy3-000 seal A, between the lower engine covers (lower cowls) and the top of the mid shaft housing has pulled out of place and broke. Does the mid section housing have to be removed to replace this seal? Thought I might be able to replace the seal by just removing the lower cowling but looking at a picture of the seal, it looks like a large "O" ring type of one continuous loop. I was hoping it was have a split in the loop where I could just insert into a grove by wrapping it around. I'd appreciate any thoughts.
