ome things belong together. Like the inner bearing retainer ring and the
bearing retainer shield on a Black Hawk’s main rotor swashplate.
But some people feel obliged to split them up. They take a screwdriver and pry
the shield from the ring. Don’t be like that. The two should stay in one piece. If
they get pried apart, the shield could get damaged. If it does, it won’t fit properly
on the ring. Then contamination can get into the bearing.
The greatest temptation seems to occur at the 500-hour swashplate lube in
Para 1-5.3 in TM 1-1520-237-23-1. Some think that once the 33 bolts are re-
moved from the inner bearing
ring to gain access to the bear-
ing seal, the next step is to re-
move the shield.
Don’t do it! The shield stays
put. You don’t need to remove
it to lubricate the swashplate
bearing.
Leave them together—forever.
