Abstract
A power take-off unit includes a housing portion, an input mechanism mounted at least partially within the housing and configured for attachment to a source of rotational energy, and an output mechanism is configured for attachment to a driven accessory. The power take-off unit also includes a clutch assembly configured to selectively connect the output mechanism to the input mechanism. A pneumatic valve manifold is attached to the housing portion and is configured to provide pressurized air to the clutch assembly.
