and make sure that bushing [31] is properly soaked with oil. Then place the friction plate, bushing,
ratchet disc (while the pawl [27] is rotated counterclockwise), and friction plate respectively on the

NEVER apply oil sin

ce the brake is a “dry system”. Thoroughly wipe out any oil

and dirt on the brake. The gear of the ratchet should point at the pawl. Otherwise, the hand wheel
cannot be assembled later.

In case the bushing does not have oil inside, soak it in turbine oil for a day. Install it without wiping the
oil. Make sure that the pawl meshes with the ratchet disc properly.
